What is the 'Regular’ Schedule.
Weekdays: Morning updates each day before 8AM, Evening Updates before 7PM.
On Weekends: Perhaps a bit later. I like to sleep in.
Every Thursday morning I post the daily forecast through the weekend.
We have had bouts of heavy rain off and on all day. We are in a lull at the moment, but a check of the radar shows us more rain is on the way. Expect more bouts of rain tonight as the wind picks up and the front approaches. Still a chance of thunderstorms and heavy downpours. Tornado Watch down in NJ.
Heavy rain and gusty winds are the primary concerns through tonight as a potent weather system moves through the region. Most areas will see a significant soaking with one to two inches of rain, though some spots could see up to three inches. While there is a brief lull in the action this afternoon, activity will ramp up again late today with the potential for embedded thunderstorms, especially near the coast and the Kennebec River Valley. Strong wind gusts between 40 and 50 mph are expected overnight, which could lead to isolated power outages. After the rain exits Tuesday morning, much colder air arrives for the middle of the week, bringing a biting chill before temperatures recover toward the weekend.
If you are commuting this evening, expect heavy downpours and reduced visibility, along with a risk of hydroplaning on wet roads. Secure any loose outdoor items like trash cans or patio furniture, as wind gusts tonight will be strong enough to toss them around. While widespread river flooding is not expected, smaller streams and urban areas with poor drainage could see some water buildup due to the combination of heavy rain and melting snow. Prepare for a much colder day Tuesday and a very sharp chill Wednesday morning, where extra layers will be necessary to combat wind chills falling into the single digits.
We saw a dizzying array of differing types of intense weather happening simultaneously around the country over the weekend. From blizzard conditions up north, wildfires in the Plains, a heat dome out west, a dangerous haboob in Texas, a rare 'Kona low' soaking Hawaii with over 40 inches of rain, and severe weather moving through the South and Midwest, it kind of felt like everything was happening all at once.
The current severe setup, which started developing yesterday in the Midwest, will threaten much of the East Coast today. The National Weather Service has issued a rare 4 out of 5 threat level for a swath of the Mid-Atlantic that includes Washington, D.C., Richmond, Virginia, and Raleigh, North Carolina. Dangerous winds and strong tornadoes are both possible as two rounds of fast-moving storms move through.

Summary:
Heavy rain and gusty winds are the primary concerns through tonight as a potent weather system moves through the region. Most areas will see a significant soaking with one to two inches of rain, though some spots could see up to three inches. While there is a brief lull in the action this afternoon, activity will ramp up again late today with the potential for embedded thunderstorms, especially near the coast and the Kennebec River Valley. Strong wind gusts between 40 and 50 mph are expected overnight, which could lead to isolated power outages. After the rain exits Tuesday morning, much colder air arrives for the middle of the week, bringing a biting chill before temperatures recover toward the weekend.
Key Messages:
- A potent low pressure system will continue to bring multiple waves of rain to nearly all of New Hampshire and western Maine through Tuesday morning. The heaviest rain will mainly fall late this afternoon and into the overnight hours. Some localized flooding is possible as a result of significant runoff and snowmelt. The risk of flooding as a result of ice jams remains low, but non, zero as some ice does remain in the mountains and northern basins.
- This system will also lead to strong winds this evening and overnight as a cold front approaches and moves through the region. The strongest wind gusts will mainly be in the 40 to 50 mph range over southern New Hampshire, coastal areas, the Interior of Maine, and the southern Kennebec River Valley. Any convection in the vicinity could lead to some higher gusts.
- Colder air briefly returns midweek with quieter weather before temperatures trend back toward normal for the second half of the week.
What has changed since the last Forecast Update?
The forecast generally remains on track with only minor changes to the big picture. While many areas are seeing a lull in precipitation early this afternoon, periods of widespread moderate to heavy rain are still expected later this afternoon and into the overnight hours before tapering off early Tuesday.
What this means for you:

Key Message 1 Description
The well advertised low continues to approach early this afternoon. Now that the initial slug of warm air advection rain, which is rain caused by warm air riding up and over cooler air, has generally pushed through, we are seeing some scattered showers in its wake. The expectation is that the radar will fill in through the rest of the afternoon as the better forcing for ascent, or the upward atmospheric shove needed to create rain, arrives. This is already starting to be observed over southern and central New Hampshire.
The heaviest rain is still anticipated late this afternoon through late tonight. Rain will then gradually taper off from west to east early on Tuesday. Storm total 1 to 2 inch values with some locally higher amounts to 3 inches still seem reasonable. For more details on the flooding potential, please see the Hydrology section below.
Finally, most of the high resolution computer models suggest the potential for at least isolated thunderstorms with this activity later this afternoon and into the evening. Forecast soundings, which are vertical snapshots of the atmosphere, are advertising around 100 to 300 Joules per kilogram of Most Unstable Convective Available Potential Energy, or MUCAPE, through the afternoon into the early evening. This MUCAPE represents the amount of fuel or energy available for storms to grow.
While the best chances for some thunder look to be along coastal areas, the Interior of Maine and up into the southern Kennebec Valley, some rumbles cannot be ruled out elsewhere given the strong atmospheric forcing and fairly steep mid, level lapse rates, which refers to how quickly the temperature drops as you go higher in the sky.
We also cannot rule out a strong to marginally severe storm given the strong wind fields right off the surface.
Key Message 2 Description
As suggested in the previous section, this system will also likely bring strong winds to much of the forecast area this evening and overnight. Forecast soundings continue to show a highly unusual low level jet, a fast moving ribbon of air a few thousand feet up, in the 70 to 90 plus knot range ahead of the approaching cold front. The strength of surface wind gusts will greatly depend on how much momentum can mix down to the ground, which is uncertain given a strong temperature inversion, a layer where air warms with height instead of cooling, in the lower levels.
This inversion acts like a lid that can prevent high winds from reaching us. Even with this lid, widespread 40 to 50 mph gusts seem reasonable, especially over coastal areas, the Interior of Maine, and the southern Kennebec River Valley. If any deeper storms move overhead, they could punch through that layer and bring stronger winds down, so it will be something to watch closely.
For now, the Wind Advisory continues to be in good shape but a short fused High Wind Warning or convective warnings for severe storms could be needed this evening depending on how the system evolves.
After the cold front moves through late tonight, winds will shift to out of the west and remain fairly gusty through the day on Tuesday. While winds will not be as strong as this evening and tonight, we will likely see widespread gusts up to 35 mph through the afternoon.
Afternoon temperatures will also only be in the upper 20s to upper 30s Fahrenheit, so it will be a raw blustery day with wind chills in the lower teens north, to the upper 20s and lower 30s Fahrenheit south.
Key Message 3 Description
A period of more tranquil but cold weather is still expected after the departure of the early week system. While specific DESI cluster language is not explicitly detailed here, these ensemble groupings generally show high agreement that northwesterly winds and very cold temperatures will allow for a bitterly cold morning on Wednesday.
Wind chills are expected to be in the single digits below zero in the mountains, with single digits above zero elsewhere.
High pressure continues through the rest of the week, with temperatures gradually warming as the mid level trough, an elongated area of low pressure, makes a slight realignment to the west.
The next chance for precipitation looks to be next weekend, though models remain very uncertain on timing and storm track.
Summary:
Southern New England is currently navigating a significant storm system that will bring heavy rain and the threat of damaging winds through early Tuesday morning. While we are experiencing a temporary break in the intensity this afternoon, a powerful resurgence of weather is expected tonight. Widespread rainfall totals of two to three inches are likely, with some areas potentially seeing up to four inches, creating a risk for river and urban flooding. The most critical window for wind arrives between midnight and 4:00 AM, where gusts could reach 60 to 70 mph in southeastern Massachusetts and Rhode Island. Conditions will dry out and turn much colder starting Tuesday, with a very chilly midweek period ahead.
Key Messages:
- Periods of heavy rain with embedded thunderstorms today, especially tonight, may lead to river and small stream flooding. Poor drainage in urban areas could flood as well.
- A period of strong to damaging winds across southern New England tonight.
- Mainly dry and trending colder Tuesday into Wednesday.
- After a cold start early Thursday morning temperatures begin moderating especially by Friday. Mainly dry weather over this time.
- Unsettled weather at times Friday night into early next week, but timing remains uncertain. Temperatures tricky this weekend depending on the location of a boundary in the vicinity of southern New England. Temperatures trending colder than normal early next week.
What has changed since the last Forecast Update?
High Wind Watches have been upgraded to High Wind Warnings across eastern Massachusetts and Rhode Island.
What this means for you
Plan for a difficult and potentially dangerous overnight period. If you live in southeastern Massachusetts or Rhode Island, be prepared for possible power outages and downed tree limbs as damaging wind gusts peak after midnight. Heavy rain will make travel difficult tonight, with a high risk of ponding on roads and flooding in low lying areas. If you are near small streams or rivers, keep a close watch on water levels. By Tuesday morning, you will notice a sharp drop in temperature, so you will need much heavier coats compared to the mild air seen today. Wednesday will be the coldest day of the week, with morning temperatures starting in the teens for many.

Discussion
Key Message 1
We are in the thick of a wet and windy storm system that will continue to impact the region through sunrise on Tuesday. After a bout of heavy and widespread rainfall this morning, we are in a relative lull this afternoon as the warm front has lifted into northern New England. This has placed us into a warm and moist airmass with temperatures as warm as the low 60s Fahrenheit while dewpoints have risen well into the 50s Fahrenheit. A very strong low level jet, a fast ribbon of air about 2,500 feet up traveling at 80 to 90 knots, will act on very anomalous moisture. Precipitable Water values, or PWATs, which measure the total amount of water vapor available in a column of air, are near 1.5 inches. This is 3 to 4 standard deviations higher than normal, meaning the atmosphere is exceptionally primed to squeeze out copious amounts of rainfall over the next 12 to 15 hours.
Following this lull in intensity, we will see a resurgence of heavy rainfall this evening and overnight ahead of the cold front. Rainfall amounts will also be juiced by any convection, or thunderstorm activity, that occurs given the environment with 400 to 600 Joules per kilogram of elevated CAPE. CAPE stands for Convective Available Potential Energy and represents the fuel available for storms. The best chance for thunder is Connecticut, Rhode Island, and central Massachusetts. When all is said and done, we are still expecting widespread 2 to 3 inches of rain with 3 to 4 inches possible in those locations that experience a thunderstorm. River Flood Warnings have been issued for some area rivers, given recent snowmelt combined with a decent rainfall will lead to minor flooding. Additionally, some localized poor drainage flooding is possible, especially under any storms.
Key Message 2
The other threat from this system is a period of strong, potentially damaging winds. As was mentioned previously, the jet dynamics with this system are very strong. This means we will have an impressive low level jet screaming overhead just above a temperature inversion, which is a layer where the air gets warmer with height, acting like a cap. Model soundings show an impressive inversion to near 950 millibars, which is typical this time of year with southerly wind events. The question is always just how much of that jet can be tapped into to pull down to the surface. The best way to tap into these winds is typically by warming the surface, as warmer temperatures allow for better mixing, and by winds being pulled down by heavy downpours.
The best shot for this event will be a fine line of storms accompanying the cold front after midnight tonight. While winds will be increasingly gusty today, gusting 35 to 45 mph by the evening, the real chance for damaging winds will be in a 3 to 4 hour window from roughly midnight to 4:00 AM. Wind gusts as high as 65 mph are possible in the southeast Massachusetts and Rhode Island area. We cannot even rule out a gust to 70 mph in the Providence to Plymouth corridor.
Key Message 3
The cold front exits east offshore well before sunrise on Tuesday, ushering in a cooler and drier airmass through Wednesday. Expect mostly sunny skies mixed with some diurnal cumulus, or fair weather clouds, thanks to the cold pool of air that moves in aloft. Temperatures at the 925 millibar level drop from 55 degrees Fahrenheit on Monday to 27 degrees Fahrenheit on Tuesday, so we can expect a significant cooldown. Highs will drop 10 to 15 degrees from Monday to Tuesday and even more so on Wednesday. Highs Tuesday will be in the low to mid 40s Fahrenheit, while Wednesday will be in the 30s Fahrenheit.
Key Message 4
Large high pressure shifts east of the region Wednesday night and Thursday. Conditions will still be favorable for a good night of radiational cooling Wednesday night, which occurs when the ground loses heat quickly under clear skies and calm winds. Expect low temperatures mainly in the teens and 20s Fahrenheit. Return southerly flow and plenty of March sunshine should allow highs on Thursday to recover back into the low to mid 40s Fahrenheit by afternoon. A warm front crosses the region late Thursday night into early Friday morning with perhaps a brief passing rain or snow shower or two. Otherwise, expect a further moderation in temperatures with highs on Friday potentially 50 degrees Fahrenheit or higher.
Key Message 5
A couple pieces of northern stream shortwave energy, which are smaller disturbances in the upper atmosphere, will result in unsettled weather at times Friday night into early next week. Specific timing is uncertain, but it appears one potential for showers will be Friday night or early Saturday. While we are not seeing specific DESI cluster language in this text, the long range ensembles, which are groups of model forecasts used to see patterns, indicate an amplifying upper trough or dip in the atmosphere over New England. This suggests temperatures will likely trend colder early next week.
A boundary in the vicinity of southern New England makes the temperature forecast tricky this weekend. Highs may be in the upper 30s and 40s Fahrenheit north of the boundary and between 55 and 65 Fahrenheit to the south.
