Rich's Weather Discussion
At this moment: 6/16 - 6:14 PM
A note from Rich:
After delivering daily weather forecasts for the last six months without a break, I realize that even I can get tired of the weather.
So I am going to take a break. Since this is a one-man operation, that means the site will go without updating during this time.
The schedule: On Thursday night, June 19th, I will deliver the final update, going out in the daily forecast section as far as I can, seven days.
I will be shutting down my weather instrument feeds, and give those drives a break. So weather readings above and on the weather readings page will not be updated during this time. Radar feeds will also not be updated during this period.
When will updates resume? The normal update schedule and all of the weather feeds will resume the morning of June 28th.
This is the longest break I have taken in many years. Thank you for coming back on the 28th.
That was a delightful late spring day!
Clouds will be on the increase tonight with cooler temperatures, clouds, and a chance of showers on Tuesday into Wednesday morning.
Temps will bounce back on Wednesday and peak on Thursday. Then a cold front arrives sometime Thursday afternoon/evening.
That cold front may produce severe storms on Thursday. Stay tuned.
Did you know that June is, on average, the third busiest month for tornadoes in the U.S.? Not only that: The area with the of tornadoes actually moves north in June as the jet stream retreats toward Canada, covering a swath of the north central U.S. that reaches all the way up into southern Minnesota. And true to form, this week we have a pattern locking in that's going to bring severe thunderstorm danger to tens of millions of people across parts of the Plains, Midwest and Great Lakes where we often see higher severe risks this time of year.
The History Section has a lot of history to share, and I will be sharing video on this page from time to time.

Area Forecast Discussion
National Weather Service Gray ME
309 PM EDT Mon Jun 16 2025
Synopsis
Areas of fog along with some drizzle will make a repeat appearance tonight, especially near the coast. Tuesday will be cooler and cloudier with occasional drizzle or light showers. Some improvement arrives Wednesday as winds shift more southerly. Expect warmer temperatures and a chance of late-day showers and thunderstorms. A stronger cold front moves in on Thursday, bringing a higher chance of showers and thunderstorms. Friday and the weekend should be mostly dry, though a few showers or storms cannot be ruled out.
Near Term through Tonight
Tonight stays on the cool and damp side with an easterly breeze wrapping around high pressure offshore. This will help fog and drizzle redevelop again, mostly along the coastal plain. Overnight lows will be mostly in the 50s.
Short Term Tuesday through Tuesday Night
A low-level onshore wind pattern and rising warmer air in the mid and upper atmosphere, referred to as "warm air advection" or WAA, continues Tuesday. This setup will lead to a rather gloomy day with lots of clouds, drizzle, and occasional light showers. High temperatures will be lowered by about 5 to 10 degrees across southern and eastern areas due to the persistent cloud cover and easterly wind. As the WAA pattern strengthens Tuesday night, expect more showers and perhaps a few rumbles of thunder.
Long Term Wednesday through Monday
Wednesday
The day starts out mostly cloudy with areas of fog, drizzle, and a few light showers. The fog will lift by mid-morning, although it may linger longer along the coast. As the day goes on, some sunshine breaks through. A weak front left behind by low pressure to our north could help kick off a few scattered afternoon showers or thunderstorms, especially in the mountains. These fade by evening. Southerly winds continue overnight, likely leading to more fog and low clouds into Thursday morning.
Thursday
A stronger cold front approaches. After fog and clouds clear out in the morning, inland areas will heat up quickly. Highs are expected to reach the mid 80s to low 90s, and possibly mid 90s in southern New Hampshire. This front brings a good chance of showers and thunderstorms, especially in western and northern areas. Some of these storms could be strong to severe, depending on how fast the front moves in. Areas along and east of Interstate 95 may see fewer storms due to cooler, more stable marine air moving in from the sea breeze.
Thursday Night into Friday
The front moves through quickly overnight, followed by breezy conditions developing either late Thursday night or Friday morning. Winds could be gusty, possibly topping 40 to 50 mph at times, based on forecast soundings that measure how winds behave with height in the atmosphere. Highs on Friday will drop into the 70s to low 80s, still feeling warm but less oppressive than Thursday.
Saturday and Sunday
A high-pressure system at about 18,000 feet (called a 500 millibar high) settles over the southeastern United States, with a ridge extending into the Great Lakes and eventually the Northeast. This ridge generally supports dry weather, but since we're on the eastern edge of it, small weather disturbances could sneak through. One such feature is hinted at by both the American (GFS) and European (ECMWF) models, possibly bringing a thunderstorm complex into the region at some point over the weekend. The details remain uncertain.
Early Next Week
Global models show increasing signals for a strong ridge of high pressure expanding over the eastern United States. If it pushes far enough north into New England, it could block storm systems from reaching our area and bring in hot conditions. With projected temperatures at around 5,000 feet (known as 850 millibar temperatures), highs on Monday could be in the 80s to low 90s, with even hotter conditions possible just beyond the forecast period.
Weather Summaries and Full Area Forecast Discussions - South (Edited)
Summary - Southern New England - Massachusetts/Northern CT/Rhode Island
A stretch of cloudy and unsettled weather continues into midweek, with patchy fog and scattered showers through Wednesday. Conditions turn hotter and more humid Thursday, with a risk of strong to severe thunderstorms as a cold front pushes through. Drier and more seasonable weather returns Friday and Saturday, but significant heat looks likely early next week, possibly the hottest of the season.
Area Forecast Discussion
National Weather Service Boston/Norton MA
343 PM EDT Mon Jun 16 2025
Synopsis
A couple of weak disturbances will bring scattered showers at times late tonight into Wednesday, with a few thunderstorms possible Wednesday. Cooler than normal temperatures Tuesday will be followed by a warming trend and hot, humid conditions on Thursday. The heat and humidity will come with a chance of thunderstorms late Thursday and into Thursday evening, some of which could be strong to severe, ahead of a cold front. More typical and drier weather is expected Friday and Saturday. Looking ahead to early next week, significant heat may impact southern New England.
Near Term (Until 6 AM Tuesday Morning)
Key Messages:
- Stratus clouds and patchy fog will redevelop
- Scattered showers possible late tonight
A weak ridge in the middle levels of the atmosphere will sit over New England tonight, along with some broad sinking air that will keep things mostly quiet for a while. However, moisture is increasing from the west ahead of a weak disturbance in the upper atmosphere, and that may lead to some scattered showers late tonight from west to east.
At the surface, high pressure will stretch westward across southern New England, and a southeast wind will keep drawing in low-level moisture. This means stratus clouds and areas of fog will redevelop and spread tonight. Low temperatures will fall into the 55 to 60 degree range.
Short Term (6 AM Tuesday Through Tuesday Night)
Key Messages:
- Mostly cloudy with scattered showers Tuesday and Tuesday night
- Cooler than normal Tuesday, but becoming more humid
An unsettled setup continues Tuesday into Tuesday night, as a couple of weak upper-level disturbances move through the region. A deep layer of moisture will settle over southern New England, with unusually high precipitable water values (PWATs) of around 1.75 to 2 inches. Although there will only be weak upward motion in the atmosphere, that amount of moisture should be enough to trigger scattered showers. These will be on and off throughout the day and night, but we are not expecting a widespread washout. Thunderstorms are unlikely, though a few convective (showery and possibly heavier) areas could pop up due to decreasing stability.
Skies will stay gloomy, with widespread low clouds. The southeast wind and thick cloud cover will keep Tuesday’s high temperatures in the upper 60s to lower 70s, which is below normal for this time of year. Dewpoints will climb into the lower to middle 60s, making the air feel a bit more humid. Tuesday night will also be milder, with lows in the lower 60s.
Long Term (Wednesday Through Monday)
Key Messages:
- Heat builds into Thursday, then cooler again by the weekend
- Risk for severe thunderstorms Thursday, mainly damaging winds
- Dry Friday and Saturday, but some showers possible during the weekend
Wednesday and Thursday
Summer warmth returns on Wednesday as high pressure offshore and a storm system moving through the Great Lakes combine to bring warm, moist southwest flow over southern New England. Temperatures a few thousand feet above the surface (around 925 millibars) will climb to about 68 degrees Fahrenheit Wednesday and close to 77 degrees on Thursday. This should translate to high temperatures in the 80s Wednesday and near 90 degrees or higher Thursday.
Dewpoints will also rise, reaching the upper 60s Wednesday and possibly the low 70s Thursday, making it feel quite humid. This increase in heat and humidity will make the atmosphere unstable, especially Thursday. Forecast models are suggesting a few thousand joules per kilogram (J/kg) of mid-level instability, or MUCAPE. This, combined with lapse rates near 7 Celsius per kilometer and winds of 30 to 40 knots in the lowest 6 kilometers of the atmosphere, points to a good chance for severe thunderstorms on Thursday. The SREF model shows a 40 to 50 percent chance of CAPE greater than 1000 J/kg and shear greater than 30 knots, with the best chances over western and central parts of southern New England.
Timing and intensity will depend on how quickly the cold front moves through. The European model (ECMWF) suggests an earlier arrival during peak afternoon heating, while the American model (GFS) is slower and brings it through after sunset. Stay tuned for updates.
Friday Through Early Next Week
By Friday and into the weekend, the region will be under a drier west to northwest flow. A weak upper-level disturbance may swing through late Saturday or early Sunday, which could bring a few showers, but confidence is low on that at this point.
What is more likely is a shift to a hotter pattern next week. Both the European (EPS) and American (GEFS) ensemble models show a strong signal for high pressure building in and bringing significant heat. There is already a 70 percent or greater chance of temperatures reaching 90 degrees or more on Monday, and even higher odds by Tuesday. This could be the hottest stretch of the year so far.
