Area Forecast Discussion National Weather Service Boston/Norton MA 1010 AM EDT Thu Oct 1 2020

SYNOPSIS. Dry weather today along with warmer than normal temperatures. Scattered showers are likely Friday, with showers most numerous northwest of Boston and Providence. Dry weather returns for this weekend. along with near normal temperatures. Coastal low pressure may bring widespread appreciable rainfall Sunday night and Monday. Dry weather likely returns Tuesday behind departing low. However, an active weather pattern may yield a chance of showers midweek.

NEAR TERM /UNTIL 6 PM THIS EVENING/. 1010 AM Update .

No major changes to the ongoing forecast this morning. Brought temperatures and winds back in line with observed trends. Still expecting abundant sunshine, with a few mid level clouds at times, particularly across NW MA. Gusty winds up to 25 mph develop towards the Cape and islands this afternoon, with lower gusts farther inland.

Previous discussion .

A positively tilted H5 trough runs from the Great Lakes into Missouri. This means that S New England remains in a predominant SW flow despite being in a post cold frontal air mass with the bulk of the cold air staying well west of us. In fact, near-term guidance indicates the milder and muggier air try to come back north so the Cape and South Coast could see dew points rise into the upper 50s to near 60. Further inland across interior MA, mixing up to 850mb should see afternoon dew points fall into the 40s. With 850mb temps around +7 to +9C, expect highs to be mainly in the low to mid 70s, which is about 5 degrees above climatological normal. Downslope flow could potentially lead to highs overperforming in Eastern MA and RI so used the MOS guidance to derive afternoon highs. Expect a steady SW winds with gusts up to 20 mph at times. Nonetheless, with plenty of sunshine and dew points in the 40s and 50s, it will be a very comfortable day for outdoor activities.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/. 420 AM Update .

Overnight Thursday into Friday .

The aforementioned H5 trough axis slowly approaches the Mid Atlantic states as it takes on a more neutral tilt. While the embedded vort max moves over Upstate NY into interior New England, a piece of energy associated with the trough will be sufficient to trigger a few autumn showers especially across interior MA beginning during the pre-dawn hours on Friday for the Western MA and reaching Eastern MA and RI by early to mid morning. The showers will bring about a reinforcing shot of cold air, with 850mb temperatures of +3C and 925 mb temperatures of +7C in the middle of the day! Locations in Western MA could remain in the mid 50s for much of Friday, while Eastern MA and RI could rise into the upper 60s or even low 70s before turning sharply cooler depending on the amount of sunshine and speed of the cold front.

There are some indications of an area of low pressure moving up the Atlantic seaboard that may help reinforce some of the showers for Eastern MA and RI but the main impact looks to be breezy conditions with gusts of 15 to 20 mph possible for locations near and along the coast. With winds turning to the south before the cold front passage, that could help boost highs along the MA/RI south coast to near 70.

Overall, rainfall amounts should be light with totals generally a quarter of an inch or less with the highest totals anticipated over western and central portions of the CWA.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/. 420 AM Update .

Highlights

* Seasonably cool weather this period

* Dry weather this weekend followed by rain likely Sun ngt/Mon with dry weather likely returning Tue, followed by a chance of showers mid week

Precipitation .

Dry weather returns Fri night behind departing short wave and associated weak coastal low. Weak short wave moves across the area Sat but column is too dry to yield any showers. Thus expecting dry weather Sat with just some extra diurnal clouds from the short wave. Short wave ridging develops over the area Sunday in response to upstream trough amplification across the Great Lakes. Therefore dry weather continues into Sunday but upstream trough sets the stage for rain chances Sun night into Monday. Euro continues to be the most amplified solution with closed low continuing to deepen as it tracks near or along the southern New England coast. Although the new 00z EC has backed off its previous deep solution. EC ensemble members are not as amplified as the 12z and previous operational runs including the 00z GFS/GEFS which are less amplified. However all model guidance including the UKMET/CMC and GFS are beginning to trend toward higher amplitude. This seems reasonable given the overall amplified long wave pattern with large western CONUS ridge and western Atlc ridge, supporting a high amplitude trough over the Great Lakes. However given the large model spread will continue to derive pops from a model blend. Dry weather should follow Tue behind departing system, however upper air pattern remains progressive but also somewhat amplified. Thus another chance of showers sometime midweek.

Temperatures .

Seasonable airmass overspreads the region this weekend, with highs in the mid to upper 60s, low 60s high terrain, with morning lows in the 40s and even a few mid to upper 30s Sunday morning. Temps Monday still a bit uncertain given different model solutions ranging from a soaking wind swept rain from a closed coastal low, to a more progressive/open wave-coastal low. Given uncertainty we will derive temps from a model blend here. Then seasonable temps Tue behind departing coastal low. WAA ahead of next short wave Wed should yield temps at or above normal.

AVIATION /14Z THURSDAY THROUGH MONDAY/. Forecaster Confidence Levels .

Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. Today: High confidence.

VFR conditions. SW winds at 5 to 10 kt with gusts up to 15 kt. Gusts up to 20 kt possible towards the Cape and islands.

Tonight: High confidence.

VFR with winds generally below 5 kt. There is a low risk for a late night rain shower west of the CT River.

Friday: High confidence.

Mainly VFR with periods of MVFR possible during showers. NW winds of 5 to 10 kt for western MA terminals and S winds of 10 kt with gusts 15 to 20 kt possible for southeast MA and Cape terminals.

KBOS Terminal . High confidence in TAF.

KBDL Terminal . High confidence in TAF. Outlook /Friday Night through Monday/ .

Friday Night: VFR. Breezy.

Saturday through Sunday: VFR.

Sunday Night: Mainly VFR, with areas MVFR possible. Chance RA.

Monday: Mainly MVFR, with areas VFR possible. Breezy. Chance RA.

MARINE. * Small Craft Advisories for outer waters today for rough seas.

Small Craft Advisories continue today for the outer waters thanks to remaining rough seas of up to 7 ft. Winds should remain below Small Craft criteria with a rather tranquil stretch of weather. There is a risk of showers on Friday with a cold front passage.

Outlook /Friday Night through Monday/ .

Friday Night: Winds less than 25 kt. Seas locally approaching 5 ft.

Saturday through Sunday: Winds less than 25 kt.
