It rained here in the Monadnocks until about 4AM. Quiet at the moment. Chance of showers today and isolated thunderstorms, but the heavy rain should be done. I will record and post the rainfall on the stats page tomorrow. We had over four inches the past couple of days. The weekend looks dry until Sunday afternoon. More on that in tonight's every Thursday Weekend Outlook e-mail. Not getting this e-mail? Sign up at the bottom of any page.
Periods of rain will continue across New Hampshire and Maine today as a strong storm system slowly moves through the region. While the risk of widespread flash flooding is decreasing, localized heavy rainfall is still possible, especially during the morning hours. Conditions gradually improve tonight, with a brief stretch of quieter weather Friday and Saturday before another round of unsettled weather arrives late Sunday into Monday.
From the Weather Channel:
Firefighters in Spain and France are in a race against the clock, scrambling to contain deadly wildfires before a new heat wave arrives. Yesterday, Spanish authorities described the first days of this week as a "crucial" window, one that could determine if crews can beat back the flames before conditions sharply deteriorate.
While we've been talking about wildfires in Oregon and Canada a lot lately, there's a crucial difference that makes these European fires particularly dangerous: Some of them are burning within miles of major population centers, including Bordeaux in France and Madrid and Valencia in Spain, meaning millions of people are potentially in harm's way. In France, the Gironde blaze grew into the country's worst forest fire since World War II, forcing over 38,000 local residents and tourists to evacuate their homes and campsites. In total, more than 300,000 people across both countries have been forced to evacuate or shelter in place.
Why is it so bad? Months of relentless heat waves, combined with a severe lack of rainfall, have left vegetation tinder-dry across the region, creating conditions ripe for fast-moving, hard-to-control blazes. And the situation may be about to get worse. A new heat wave is forecast to sweep across western Europe this week, with temperatures expected to hit 104 degrees or higher in some areas by midweek. It would be the continent's fourth bout of extreme heat since May, and forecasters warn it could spark dangerous new fires just as crews are fighting to contain the ones already burning.

Weather Summaries and Full Area Forecast Discussions - North (Edited)
Summary - Northern New England - New Hampshire and Maine
Summary:
Periods of rain will continue across New Hampshire and Maine today as a strong storm system slowly moves through the region. While the risk of widespread flash flooding is decreasing, localized heavy rainfall is still possible, especially during the morning hours. Conditions gradually improve tonight, with a brief stretch of quieter weather Friday and Saturday before another round of unsettled weather arrives late Sunday into Monday.
Key Messages:
- Slow moving low pressure will continue to bring rain to the area through this afternoon. Localized heavy rainfall remains possible, though the flash flood threat is diminishing.
- A quick break in the weather is expected to start the weekend, with a return to unsettled weather late Sunday into Monday.
What has changed since the last Forecast Update?
Heavy rain and the potential for flash flooding are becoming more localized through the morning hours.
What this means for you:
If you have outdoor plans today, expect periods of rain with the possibility of locally heavy downpours that could cause isolated flooding in poor drainage and low lying areas. While the overall flood threat is lower than it was earlier, some locations could still receive several inches of rain in a short period of time. Friday and Saturday offer a break with warmer conditions, although a few afternoon showers or thunderstorms remain possible. Another slow moving weather system is expected to bring increasing chances for rain and thunderstorms late Sunday into Monday.

**What Has Changed**
Heavy rain and the potential for flash flooding are becoming more localized through the morning hours.
**Key Messages**
1. Slow moving low pressure will continue to bring rain to the area through this afternoon. Localized heavy rainfall remains possible, though the flash flood threat is diminishing.
2. A quick break in the weather is expected to start the weekend, with a return to unsettled weather late Sunday into Monday.
**Discussion**
**Key Message 1 Description**
An unusually strong large scale weather system, known in meteorology as a synoptic system, continues to move across the Northeast today. A deep upper level trough, an elongated area of lower pressure in the atmosphere, and a strong surface low pressure system for this time of year will move through the Gulf of Maine this evening before slowly drifting east. This will keep the region at risk for periods of heavy rain and isolated flooding.
The latest high resolution forecast models, known as CAM guidance, continue to show differences in exactly where the heaviest rain will fall, but they generally agree on the timing. Most guidance indicates showers and thunderstorms will become more active between 2 AM and 8 AM. Some locations could receive more than 2 inches of rainfall during that period. Current trends suggest southwestern Maine may have the greatest chance for the heaviest rain, but radar has not yet confirmed that shift. Because of that uncertainty, the Flood Watch remains in place since the heavier rain could still develop over New Hampshire.
During the afternoon, the greatest chance for rainfall will shift toward the coast. Forecast models indicate the rain will become more convective, meaning it will occur in scattered heavier downpours and thunderstorms rather than widespread steady rain. As the low pressure system moves farther east and daytime heating fades this evening, showers and thunderstorms will quickly decrease.
**Key Message 2 Description**
By Friday, conditions will improve, although the region will remain under a cooler pocket of air aloft associated with the departing weather system. This will generally allow for more sunshine during the morning, followed by increasing clouds and the chance for scattered afternoon showers and thunderstorms. A similar pattern is expected on Saturday, although any showers will be fewer and more isolated.
By Sunday, the next upper level trough will approach from the west. Winds in the upper atmosphere will become southwesterly and will run nearly parallel to an approaching cold front. This setup is expected to slow the movement of the front, allowing rain chances to continue through Sunday and into Monday. Forecast guidance suggests this event may unfold in two phases. The first round could produce showers and thunderstorms across western areas on Sunday before weakening. A second round may develop farther east on Monday before moving out of the region later in the day.
Weather Summaries and Full Area Forecast Discussions - South (Edited)
Summary - Southern New England - Massachusetts/Northern CT/Rhode Island
Summary:
Periods of showers will continue across southern New England today, although the rain will be lighter and less widespread than Wednesday. Conditions gradually improve Friday with fewer showers, increasing sunshine, and warmer temperatures returning to the upper 70s to lower 80s. The weekend looks pleasant overall with a mix of clouds and sunshine, seasonable temperatures, and a bit more humidity. Another cold front is expected to bring the next chance of showers and thunderstorms late Sunday into Sunday night, with a few showers possibly lingering into Monday along the southeast coast.
Key Messages:
- Showers linger across southern New England today. Friday will still see some showers, though more scattered and accompanied by increasing breaks of sun.
- Mix of clouds and sun with seasonable temperatures and some humidity this weekend. Next chance for showers and thunderstorms returns with a frontal boundary moving in late Sunday into Sunday evening, possibly lingering into Monday along the southeast coast.
What has changed since the last Forecast Update?
No significant changes.
What this means for you
Today will still be damp with occasional showers, but the threat of widespread heavy rain has eased. Friday brings improving conditions with more sunshine and warmer weather. The weekend is shaping up well for most outdoor plans, although it will feel a little more humid. If you have plans late Sunday or Sunday evening, keep an eye on the forecast as another round of rain and thunderstorms may move through. While heavy rainfall is not expected to be widespread, a few locations that have already received significant rain could see localized flooding if heavier showers develop.

**What Has Changed**
No significant changes.
**Key Messages**
* Showers linger across southern New England today. Friday will still see some showers, though more scattered and accompanied by increasing breaks of sun.
* Mix of clouds and sun with seasonable temperatures and some humidity this weekend. Next chance for showers and thunderstorms returns with a frontal boundary moving in late Sunday into Sunday evening, possibly lingering into Monday along the southeast coast.
**Discussion**
**Key Message 1, Showers linger across southern New England today. Friday will still see some showers, though more scattered and accompanied by increasing breaks of sun.**
A more manageable amount of rain is expected today compared to Wednesday as an upper level low pressure system continues to spin over the region. The surface low will shift east over the Gulf of Maine, causing lower level winds to turn north. This will reduce the added rainfall that typically develops over higher terrain, a process known as **orographic enhancement**. At the same time, the **low level jet**, a narrow corridor of stronger winds a few thousand feet above the ground, will also move away from southern New England.
Even with these changes, colder air aloft, around **10 to 14 degrees Fahrenheit** at the middle levels of the atmosphere, combined with **Positive Vorticity Advection (PVA)**, a process that encourages air to rise, abundant atmospheric moisture, and a fully saturated atmosphere, will continue to support low clouds and periods of light to moderate rain showers.
By Friday, the upper level trough will move into the Canadian Maritimes, allowing higher pressure aloft to build into southern New England. This is a sign of improving weather and will allow drier air to move into the region. As a result, shower coverage will decrease while sunshine becomes more common. The building ridge of high pressure will also bring a warmer air mass into the area, allowing afternoon temperatures to reach the upper 70s to lower 80s for the first time in several days.
**Key Message 2, Mix of clouds and sun with seasonable temperatures and some humidity this weekend. Next chance for showers and thunderstorms returns with a frontal boundary moving in late Sunday into Sunday evening, possibly lingering into Monday along the southeast coast.**
The weekend looks favorable overall. High pressure to the south will bring a mix of clouds and sunshine, seasonable temperatures in the low to mid 80s, and a modest increase in humidity.
Weather conditions become more unsettled late Sunday into Sunday evening, with some forecast guidance suggesting showers could linger into part of Monday. Another fairly strong upper level trough moving across Ontario and Quebec will push a slow moving cold front into the Northeast.
This front will tap into deeper moisture, with atmospheric moisture values increasing to between 1.5 and 1.7 inches, above normal for early August. This will provide the next opportunity for showers and thunderstorms, with most forecast guidance favoring late Sunday afternoon through Sunday night.
Artificial intelligence based severe weather guidance continues to indicate only a limited chance of severe thunderstorms. That is supported by relatively weak winds higher in the atmosphere and the evening arrival of the front, which limits the amount of daytime heating available to fuel stronger storms.
Although this system is not expected to produce the prolonged rainfall seen earlier this week, it could still bring locally moderate rainfall. Guidance from the **European Ensemble Prediction System (EPS)** and the **Global Ensemble Forecast System (GEFS)** indicates a 40 to 70 percent chance of at least one half inch of precipitation over a 24 hour period, while the chance of more than one inch remains below 30 percent.
Some parts of interior southern New England have already received substantial rainfall during the past 24 to 48 hours. Those areas should continue to be monitored for localized flooding if heavier showers develop, although the overall flood risk remains low.
There remains some uncertainty regarding whether a disturbance rotating around the southern side of the upper level trough will develop into a closed area of low pressure over the lower Ohio Valley. If that occurs, most of southern New England should still begin clearing by early Monday, although lingering clouds and a few showers could remain near the southern coastal waters and parts of southeastern New England. Future forecast updates will determine whether that scenario becomes more likely.
