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.
Upcoming Site Update Schedule Changes:
There will be NO morning updates on Monday 7/27. There may be an evening update, otherwise, normal updates resume on Tuesday morning, 7/28.
Sunny and seasonably warm today with highs in the low to mid 80s.
We really have a gorgeous weekend ahead. Bright sunny skies Saturday and Sunday. Average mid summer temps in the low to mid 80s. Low humidity all the way through Sunday. What more could you ask for?
I see excellent weather for any outdoor plans Saturday/Sunday, with a good chance this stretch will last into Monday.
Pleasant summer weather will continue across the region through the weekend as high pressure remains in control. Expect warm afternoons, cool and comfortable nights, and mainly dry conditions. Early next week, the weather pattern becomes more unsettled with increasing chances for precipitation on Tuesday and Wednesday, including periods of heavy downpours and thunderstorms. While confidence is high that wetter weather will return, the exact timing and track of the storm system remains uncertain. Seasonable temperatures are expected to continue through next week.

**What Has Changed**
Some valley fog developed this morning and will continue for another hour or two before lifting. No major changes were needed with this forecast update.
**Key Messages**
1. Pleasant weather continues through the weekend under high pressure.
2. Precipitation chances increase Tuesday and Wednesday, but conditions improve toward the second half of the week. Seasonable temperatures continue.
**Discussion**
**Key Message 1 Description**
A broad area of high pressure will settle directly over the region today through Saturday, bringing continued fair weather. Afternoon temperatures will reach the 80s while overnight lows fall into the 50s, providing comfortable sleeping weather. Sea breezes are expected to develop each afternoon along the coast and gradually move inland, helping keep coastal communities a little cooler. High pressure remains in control through Sunday before slowly shifting east of New England.
**Key Message 2 Description**
An upper level low pressure system moving across Hudson Bay will strengthen a trough, an elongated area of lower atmospheric pressure, over the Northeast early next week. In response, a surface low pressure system is expected to track across either New England or southern Quebec.
Since this system is still about five days away, forecast models continue to show different solutions. The GFS and GEFS (Global Ensemble Forecast System) generally track the system farther south, move it through more quickly, and keep it somewhat weaker. The ECMWF and EPS (European Centre for Medium Range Weather Forecasts Ensemble Prediction System) favor a farther north track with a somewhat stronger system. Because of these differences, the exact timing and location of the wettest weather remains uncertain.
For local impacts, the overall setup resembles the recent period of heavy rain and thunderstorms, although this event currently appears less extreme. Forecast confidence is high that atmospheric moisture will increase significantly, with precipitable water values reaching at least 1.5 inches and dew points climbing well into the 60s. This combination supports the potential for heavy downpours.
Forecasters also expect a pocket of cooler air higher in the atmosphere, often called a cold pool aloft, which can make the atmosphere more unstable when sunshine develops. As a result, several rounds of heavy showers and thunderstorms are possible Tuesday and Wednesday, especially during the afternoon when daytime heating produces the greatest instability.
Even with higher humidity, temperatures should remain close to normal for late July, or even a little cooler than average, because of increased cloud cover and cooler air aloft.
Weather Summaries and Full Area Forecast Discussions - South (Edited)
Summary - Southern New England - Massachusetts/Northern CT/Rhode Island
Summary:
A stretch of pleasant summer weather continues through the weekend with dry conditions, comfortable humidity, and seasonable temperatures. High pressure will keep skies mostly sunny through Saturday before a weak weather system approaches on Sunday, bringing the possibility of more clouds and a little patchy drizzle, mainly across eastern Massachusetts. A more unsettled weather pattern develops late Monday through the middle of next week with several opportunities for showers and thunderstorms. While it will not rain all the time, some storms could produce locally heavy rainfall and a few could become strong, especially Tuesday and Wednesday.
Key Messages:
- Mainly dry conditions expected through the weekend with seasonable temperatures.
- Periodic chances for showers and thunderstorms late Monday through mid week, potentially lingering into Thursday.
What has changed since the last Forecast Update?
No significant changes to the forecast.
What this means for you
If you have outdoor plans this weekend, the weather should cooperate with warm afternoons, cooler nights, and generally dry conditions. Those along the eastern Massachusetts coastline may notice cooler temperatures because of an onshore breeze, with increasing clouds possible on Sunday. Beginning late Monday, keep an eye on the forecast as several rounds of showers and thunderstorms are expected through midweek. Some storms may bring heavy precipitation and gusty winds, but there will also be dry periods between systems.

**What Has Changed**
No significant changes to the forecast.
**Key Messages**
* Mainly dry conditions expected through the weekend with seasonable temperatures.
* Periodic chances for showers and thunderstorms late Monday through mid week, potentially lingering into Thursday.
**Discussion**
**Key Message 1, Mainly dry conditions expected through the weekend with seasonable temperatures**
High pressure at the surface will continue building over southern New England today while winds several thousand feet above the ground become more west to east, a pattern meteorologists call zonal flow. High pressure overhead will keep winds light and variable, allowing local sea breezes to develop along the coast during the afternoon.
High temperatures today will reach the lower to middle 80s. Another clear night will allow heat to escape efficiently after sunset, a process known as radiational cooling, bringing overnight lows into the 50s to around 60 degrees.
On Saturday, the center of the high pressure system shifts offshore, causing winds to turn easterly. Dry weather and mostly sunny skies are expected to continue. Interior locations should warm into the lower to middle 80s, while communities along the eastern coastline remain cooler, generally in the middle to upper 70s because of the onshore wind.
By Sunday, an upper level trough, an elongated area of lower pressure in the atmosphere, approaches from the west. Forecast models also suggest a low pressure system may pass offshore. Some of the higher resolution forecast models are becoming more aggressive in bringing Atlantic moisture inland later Sunday, especially across Cape Cod and the Islands.
Forecast soundings, which are atmospheric profiles used by meteorologists, suggest shallow moisture near the ground with drier air higher up. This setup could produce low clouds and areas of patchy drizzle across parts of eastern Massachusetts during the day. Other forecast models show a weaker signal, so confidence remains somewhat lower. Forecast details should become clearer as newer, higher resolution model data becomes available.
**Key Message 2, Periodic chances for showers and thunderstorms late Monday through mid week, potentially lingering into Thursday**
Forecast guidance continues to show good agreement that an upper level trough will remain over the region through much of next week. Several smaller disturbances, known as shortwaves, are expected to move through the flow, creating periodic opportunities for showers and thunderstorms.
Winds become more southerly on Monday, allowing additional moisture to move into southern New England ahead of the first disturbance. By Tuesday, atmospheric moisture levels are expected to increase significantly, with precipitable water values reaching between 1.50 and 2.00 inches. This means the atmosphere will contain plenty of moisture to support heavier precipitation.
As a result, periods of showers and thunderstorms become increasingly likely from late Monday through the middle of next week. If the upper level trough moves more slowly than expected, the unsettled weather could continue into Thursday.
Current guidance suggests this will not be a complete washout. Instead, showers and thunderstorms are expected to develop mainly during the afternoon and evening hours as daytime heating helps fuel storm development.
Because of the unusually moist atmosphere, any thunderstorms that develop could produce localized heavy precipitation. There is also some indication that a few storms could become strong to severe on Tuesday and Wednesday. The National Severe Storms Laboratory (NSSL) machine learning probabilities are highlighting this potential because forecast conditions may support stronger thunderstorm development with increasing atmospheric instability and favorable wind shear. This is something to monitor over the coming days.
Temperatures through the first half of next week should remain close to normal or slightly below normal for late July.
