Area Forecast Discussion National Weather Service Boston/Norton MA 1003 PM EDT Thu Apr 22 2021

SYNOPSIS.

Breezy and chilly weather expected tonight, followed by dry conditions and a warming trend Friday into Saturday. A coastal storm will bring periods of rain Sunday followed by blustery and drier conditions Monday. Dry and much warmer weather the rest of next week as high pressure builds into the region.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/.

10 PM Update .

No changes in the latest update. Have just brought things in line with the latest observations. Rest of the forecast is on track.

745 PM update .

Diurnal cloudiness had dissipated over most of the region this evening. West to west-northwest winds still were gusting to 20-30 mph. No changes to the current forecast.

Previous discussion .

Tonight .

Surface low pressure lingers over the Canadian Maritimes tonight. However at H500, center of cutoff low that was over our area today, moves northeast and away from our area tonight. While cyclonic flow persists tonight, expect to see decreasing cloud cover as high pressure nudges in from the south.

We continue to have a tight pressure gradient in place, so expecting gusty W/WNW winds to persist tonight, except diminishing after this evening in valleys and lower terrain away from the coastline.

Temperatures will remain cold with 850 hPa temperatures around -5 degrees Celsius at daybreak Friday. Lows tonight should range from the upper 20s to mid 30s across much of the area, with mid to upper 30s along the east coastal MA shoreline, Cape and Islands. Have overnight lows in the low 30s across northern CT, RI away from the Providence Metro area, and SE MA away from the coast. In those locales, Frost/Freeze Warning program began on 4/21. Thus issuing a Freeze Warning for tonight for those locales.

SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/.

Friday .

A dry day with mostly sunny skies expected, as the Canadian Maritime low moves further away from our area, high pressure builds in from the SW, and rising mid level heights. Model soundings show enough moisture below the subsidence inversion to allow for some diurnal stratocumulus. A tight pressure gradient lingers over our area, so gusts of 25 to 35 mph will likely occur once diurnal heating gets going.

Temperatures moderate as W to WNW flow aloft advects in warmer air. This will bring in +4 to +7 degree Celsius 925 hPa air. Given the flow provides a downslope component, that should allow for some added heating as well. High temperatures in the mid 50s to low 60s are forecast.

The gusts of 25-35 mph combined with dewpoints in the low to mid 20s bring the potential for elevated fire weather potential across southern New England once again. See the Fire Weather section below for more details.

Friday Night .

Dry weather will prevails with clearing skies. High pressure remains to our south, with westerly flow in place. Overnight lows a bit more mild, in the mid 30s to low 40s, except low to mid 40s Cape/Islands.

LONG TERM /SATURDAY THROUGH THURSDAY/. Highlights

* Cool with periods of rain late Saturday night into Sunday evening * Dry and blustery Monday * Dry Tue through Thu and much warmer . reaching the 80s Thu

Saturday .

Dry weather will prevail with high pres to the south and westerly flow in place. Lots of sunshine Sat although mid/high clouds ahead of next system will begin to move into the region in the afternoon. Nice warming trend on Sat with deep mixing up to 800 mb. Expect highs approaching 70 for many interior locations, but cooler along the immediate south coast and higher terrain.

Saturday night into Sunday night .

A progressive upper level trough moves from the Ohio Valley Saturday evening to off the Massachusetts coast Sunday evening. It surface low pressure reflection is forecast to move from the Mid- Atlantic coast northeastward to near or just south of Nantucket. There still remains some model differences, but all models spread rain from SW to NE across the region Saturday night, mainly after midnight. Rain should continue much of the day on Sunday, with the steadiest in the southeastern half of southern New England. Looks like 0.25 to 0.75 inches of rain is possible . with 1 inch not out of the question in southeast areas, closer to the low track. Clouds, precipitation, and onshore flow will keep high temperatures in the 50s.

Southeast winds at 925 mb may reach 50 kt, with gusts of 25-35 mph at the surface out ahead of the low Sunday afternoon, mainly along the southeast coastal areas. The system progresses off the coast by Sunday evening, with winds shifting to the north to north- northwest. Speeds diminish in the late afternoon and early evening, but increase again to 40-50 kt at 925 mb late Sunday night. This could mean northwest gusts to 20 to 30 mph continuing across much of the region overnight.

We are still monitoring the potential for some minor coastal flooding. However, at this time, the southeast flow will not have had time to build up very much by the late Sunday morning high tide, which is the lower of the two high tides that day. A 1.0 to 1.5 ft storm surge would bring the possibility of some splashover to a few southeastern-exposed areas. By the Sunday night high tides, the winds will have shifted to the north or north-northwest. Thus, the area of concern will mainly be in the inner portion of Cape Cod Bay. Models are showing the potential for 1.0 to 1.5 ft of storm surge, which could lead to a possibility of low-end minor coastal flooding . i.e., a few coastal roads with water on them. A change in strength, track, or timing of the low, still could impact this forecast.

Monday .

Still blustery but dry and cool on Monday behind the storm system, with highs mainly around 60 but cooler at the coast.

Tuesday through Thursday .

An upper level ridge of high pressure builds into the area through the midweek period, with dry weather. This will bring a pronounced warming trend with highs Tuesday approaching 70, high Wednesday 75 to 80 . and highs Thursday in the lower 80s!

AVIATION /02Z FRIDAY THROUGH TUESDAY/.

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

2345Z Update .

MARINE.

10 PM Update .

Have converted the Gale Warnings for Boston Harbor and Narragansett Bay to Small Craft Advisories as winds will continue to gust between 25-30 overnight into Friday morning. The gusty winds will gradually diminish Friday afternoon.

745 PM update .

* Gale Warnings continue into tonight.

No changes to the current forecast. Boston Harbor buoy 44013 was still gusting to 34 kt (gale force) early this evening.

Tonight . High confidence

West winds 20-25 kts overnight, with gusts to around 35 kts. The Gale force gusts gradually diminish across most of the waters, however on the eastern outer coastal waters gusts to 35 kts continue into Friday morning. Seas 5 to 8 feet.

Friday . High confidence

Westerly winds at 15-25 kts with gusts to 30 kts. On eastern outer waters, gusts to 35 kts early, thus Gale Warnings continue into Friday morning there, then winds diminishing to 30 kts by midday. Seas 5-8 feet. On the northern waters, seas gradually diminishing to 3 to 5 feet.

Friday night . High confidence.

SCA headlines may be needed for the southern waters, due to seas 3 to 5 feet and west winds gusting to 25 kts. For northern waters, seas 2 to 4 feet with west winds gusting to 20 kts.

Outlook /Saturday through Tuesday/ .

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

Saturday Night: Winds less than 25 kt. Chance of rain showers.

Sunday: Moderate risk for Small Craft Advisory winds with gusts up to 25 kt. Local rough seas. Rain showers.

Sunday Night: High risk for Small Craft Advisory winds with gusts up to 30 kt. Areas of rough seas. Chance of rain showers.

Monday: Moderate risk for Small Craft Advisory winds with areas of gusts up to 30 kt. Areas of rough seas.

Monday Night: Winds less than 25 kt. Local rough seas.

Tuesday: Winds less than 25 kt.

FIRE WEATHER.

* Elevated Fire Weather Potential across much of southern New England again on Friday.

As highlighted above in the short term section, Friday will feature gusty westerly winds and deep boundary layer mixing. The vast majority of areas did not receive 0.5 inches of precipitation from the storms on Wednesday. Given this coupled with the strong winds and low relatively humidities, have gone with a Special Weather Statement to highlight the Elevated Fire Weather Potential per coordination with fire weather partners. Should see minimum relative humidities fall to 25 to 35 percent with gusts of 25 to 35 mph.

BOX WATCHES/WARNINGS/ADVISORIES. CT . Freeze Warning until 8 AM EDT Friday for CTZ002>004. MA . Freeze Warning until 8 AM EDT Friday for MAZ013-017-018. RI . Freeze Warning until 8 AM EDT Friday for RIZ001-003-006. MARINE . Gale Warning until 2 AM EDT Friday for ANZ231>235-237-255-256. Small Craft Advisory until 8 PM EDT Friday for ANZ230-236.
