Back on the regular schedule
Good - Bye September! Hello October! It will feel like summer, then fall returns by the weekend.
A warmer and mostly dry Thursday will lead into an unusually warm Friday, with some locations possibly reaching 80 degrees. A series of fronts will then bring a more typical fall pattern for the weekend and early next week, with occasional showers, cooler temperatures, and breezy conditions. Frost is possible in the foothills Saturday night, while Tuesday could be quite cool, with highs staying in the 50s.
Thursday and Friday will feel more like late summer than early October, with temperatures well above normal and mostly dry weather. The weekend turns cooler and more fall-like as fronts move through, bringing chances for showers and periods of breezy weather. Saturday night could be cold enough for some frost in the foothills, while Tuesday may remain in the 50s despite mostly sunny skies.
Hurricane Polo made landfall on Mexico's Baja peninsula early Tuesday as a Category 2 with 110 mph winds, and what's left of it arrives in the U.S. today.
Flash flood watches stretch from Phoenix to Des Moines, putting more than 30 million people at risk. Roads in southern New Mexico were already underwater Tuesday.
Texas gets the worst of it next. Dallas-Fort Worth is looking at 1 to 4 inches starting today and running through Thursday.
Polo peaked at 180 mph over the weekend, tied for the third-strongest storm ever recorded in the eastern Pacific. It went from 45 mph to 150 mph in a single day, a jump forecasters called "truly remarkable."
Tropical Storm Fay has dissipated.
Tropical Storm Hanna has dissipated.

**What has Changed**
Temperatures have been lowered for the rest of today based on recent trends in cloud cover.
**Key Messages**
1. Warmer temperatures are expected Thursday with mostly dry conditions continuing.
2. Through the weekend will be more of a typical fall pattern. A series of fronts cross the region with chances of showers followed by cool and breezy conditions.
**Discussion**
**Thursday**
Although recent forecast guidance has not handled the situation particularly well, the lower atmosphere is expected to become drier this afternoon. This should eventually allow the stubborn layer of low clouds to lift and thin out. Until then, areas of drizzle are possible for the next couple of hours, mainly across southwestern Maine where cloud bases are currently lower.
The chances of seeing much sunshine this afternoon are already fairly low and will decrease further as high clouds move in from the west. These clouds should continue to increase and thicken this evening and tonight as a disturbance several miles above the surface approaches.
Afternoon high temperatures have therefore been lowered by a couple of degrees. However, the increasing clouds should limit overnight cooling and keep temperatures mostly in the lower 50s tonight. Patchy fog is expected across much of the area tonight into Thursday morning. Forecast guidance from the High-Resolution Ensemble Forecast system, or HREF, is particularly highlighting fog along and east of the Interstate 95 corridor in western Maine, although the amount of fog remains uncertain because of the cloud cover.
High pressure will remain in control Thursday, keeping conditions mostly dry. Forecast data shows some drying behind the disturbance moving through tonight, which should allow for more sunshine, especially during the first part of Thursday. Clouds will then increase from west to east during the afternoon, particularly across New Hampshire, where a few sprinkles are possible as moisture increases ahead of a frontal boundary.
Temperatures several thousand feet above the surface are expected to be around 50 to 54 degrees, supporting afternoon highs in the mid to upper 70s. That would be roughly 10 degrees above normal for the first day of October.
**Thursday Night**
Clouds will continue to increase Thursday night, with a light south to southwest breeze. The breeze and clouds should limit fog development somewhat while also keeping overnight temperatures unusually mild, mainly in the 50s and 60s. A few showers are possible in the mountains, but most areas should remain dry.
**Friday through Early Next Week**
Friday will be another very warm day as warm air continues moving into the region ahead of the next approaching front. Forecast guidance points to temperatures 10 to 15 degrees above normal across the area. Some locations could approach 80 degrees. While very warm for early October, temperatures are expected to remain at least 5 degrees below record levels for this time of year.
The National Blend of Models, or NBM, may also be running slightly warm as the region begins transitioning from the warm season toward the colder season.
Rain along the front should be mainly in the form of showers, with relatively weak weather systems along the boundary. Some areas could miss the rainfall entirely, while other locations may receive only a small amount.
The first front will bring temperatures back toward normal for the weekend. Saturday night is expected to be clear and calm, making it the coldest night of the weekend. Some frost is possible in the foothills, although those areas are no longer included in the frost and freeze program.
A stronger disturbance is forecast to cross the region late Sunday into Monday. Confidence is lower regarding rainfall with this system. Less than half of forecast ensemble members indicate measurable rainfall across the forecast area, especially farther south. There is greater confidence that cooler-than-normal air will follow behind the system.
By Tuesday, temperatures may struggle to get out of the 50s under mostly sunny skies, with breezy west winds.
Weather Summaries and Full Area Forecast Discussions - South (Edited)
Summary - Southern New England - Massachusetts/Northern CT/Rhode Island
Summary:
A pleasant and warming trend is underway across the region, bringing mild temperatures and clear skies through Friday. A cold front will then arrive on Friday evening bringing scattered showers, followed swiftly by a much cooler and crisp autumn airmass that will establish itself across Southern New England early next week, bringing potential frost to interior locations.
Key Messages:
- Warm and pleasant stretch of weather arrives later this afternoon through Friday evening.
- Next chance for showers arrives Friday evening along and ahead of a rather strong cold front.
- Dry and seasonable this weekend, but with more clouds on Sunday.
- Much cooler autumn airmass settles over Southern New England early to middle of next week.
What has changed since the last Forecast Update?
No significant changes.
What this means for you
You can look forward to pleasant, warmer weather through the end of the work week, making it a great window for outdoor activities before cooler fall temperatures arrive. If you have sensitive plants outdoors, you will want to monitor the forecast closely for potential frost by early next week as significantly colder air moves into the region.

Discussion
Warm and pleasant stretch of weather arrives later this afternoon through Friday evening.
Confidence remains high that weather conditions will improve this afternoon through Friday as an upper level high pressure ridge builds over the region. Currently, low clouds and light drizzle linger across eastern Massachusetts and Rhode Island. High resolution computer models show this stubborn cloud layer mixing out over the next several hours to give way to clearing skies. Patchy fog may form overnight inland due to abundant moisture and light winds as the lower atmosphere decouples. Temperatures this afternoon will be noticeably warmer than recent days, with highs reaching the upper 60s to lower 70s today, and climbing into the mid 70s to near 80 degrees on Thursday and Friday.
Next chance for showers arrives Friday evening along and ahead of a rather strong cold front.
The next round of showers arrives after sunset on Friday as a low pressure system moves across Ontario and Quebec, pushing a cold front toward the region. Computer guidance trends later and weaker with precipitation, with the highest rain probabilities of 30 to 50 percent occurring after sunset Friday. Rainfall amounts will be light, with less than a quarter inch of precipitation expected. Most guidance indicates the front will stall just south of local coastal waters.
Once the low moves through Quebec, a strong continental high pressure system will build over Ontario, pushing airmass temperatures equivalent to 39 to 43 degrees Fahrenheit at about 5000 feet down into New England and sharply lowering surface temperatures through the weekend. Overnight lows will drop into the upper 30s to lower 40s, while daytime highs reach the mid 60s.
Dry and seasonable this weekend, but with more clouds on Sunday.
The weekend forecast looks more favorable than it did 24 hours ago. Recent computer guidance cycles indicate that the strong high pressure system building on Saturday will stay strong enough through Sunday to block rain showers from moving northward from the southern waters. Sunday will remain mostly cloudy, but dry weather will prevail, even as a strong upper level disturbance in the northern jet stream tracks eastward along the United States and Canada border Sunday night, pushing a dry cold front southward into the Sunday night to early Monday time frame.
Saturday will likely be the best day of the weekend with mostly sunny skies and highs in the mid to upper 60s, though temperatures will stay in the lower 60s along the eastern and southeastern coast due to northeast onshore breezes. Highs on Sunday should be a couple of degrees cooler due to increased cloud cover.
Much cooler autumn airmass settles over Southern New England early to middle of next week.
Model guidance remains consistent regarding a dry, blustery, and much cooler autumn air mass for early to mid next week. This happens as a strong upper level trough develops over the Northeast, with a strong surface high pressure system of 1030 millibars originating over the Great Lakes and settling over New England by Tuesday night. Strong cold air advection begins Monday afternoon, with temperatures at the 5000-foot level dropping as low as 28 degrees Fahrenheit by 8 AM Tuesday.
Expect full sunshine and dry weather on Monday, though it will be breezy with a tight northwest pressure gradient. Highs will reach the lower to mid 60s with overnight lows in the upper 30s to mid 40s. Even colder weather arrives by Tuesday, with highs only reaching the mid 50s. Depending on how quickly winds die down Tuesday night, some areas could experience their first frost since last spring, with interior lows dropping into the lower to mid 30s, cities seeing upper 30s to mid 40s, and coastal areas near the eastern and southeastern shores staying in the lower to mid 40s.
