Area Forecast Discussion National Weather Service Boston/Norton MA 743 PM EDT Tue Mar 31 2020

SYNOPSIS. Closed upper low pressure lingers over New England through midweek, but should see mainly dry conditions. An ocean storm will pass well south of the region late this week, bringing gusty and cool northeast winds especially along east coastal areas. An area of rain will move onshore across the region Wednesday night into Friday morning, with wet snow possible especially across the high terrain. High pressure will bring dry but continued cool conditions Saturday. Another weak, fast moving system will bring unsettled weather on Sunday, then dry conditions return early next week.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. Main changes this evening were to adjust sky cover per latest satellite data. Mainly clear across southern New England, with some clouds lingering just east of Cape Cod and Nantucket, as well as towards the Berkshires.These clouds were moving from NE to SW. Above these, were some higher clouds generally moving from W to E. Expecting the higher clouds to arrive first, with the lower clouds filling back in after midnight as the lower level humidity increases. Not thinking there is enough moisture for showers, but cannot entirely dismiss the idea of a few sprinkles towards the Cape and islands.

Minor tweaks to temperatures to bring them back in line with observed trends.

Previous Discussion .

Cool high pressure nosing southward into New England providing dry but chilly weather. Few low top showers trying to pop over the high terrain of western MA but as diurnal heating wanes this isolated activity will diminish. Otherwise decreasing clouds over Cape Cod and the Islands this evening. Clouds likely lift but persist somewhat over western CT/MA this evening and overnight.

As for temps sided with the cooler MOS guidance as winds decouple away from the coast and with dew pts in the 20s temps will get chilly overnight. After 06z winds shift more to the NE and increase. This may result in low clouds coming back onshore along with some light spotty rain/showers into southeast MA. Temps will likely level off or even rise a few degs late given increasing clouds and NE winds especially over southeast MA.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/. Tomorrow will be watching mid level low emerging out of the TN Valley this afternoon as it tracks ENE off the Mid Atlc coast Wed morning. Dry weather prevails across our region but clouds may dominate the day across eastern MA given NE onshore flow and perhaps some light rain late in the day over Cape Cod and Islands. However farther inland across RI/CT and western-central MA expecting dry weather to prevail with at least partial sunshine. Despite the partial sunshine inland temps will remain chilly given same airmass in place. Expecting highs in the mid to upper 40s inland and upper 30s to lower 40s across eastern MA. Thus another cooler than normal day and gusty NE winds up to 25-30 mph across Cape Cod and Islands will add to the chilly conditions.

Wednesday night .

Low tracking well southeast of New England and deepens to about 980 mb by 12z Thu as it enters southeast Georges Bank. While most of our area will remain dry given this distant storm track, the mid level circulation is very large and wraps warm air aloft (TROWAL) back into New England. This will support a risk of rain entering eastern MA. Per model soundings column is cold enough to support some light snow per wet bulb temps but precip may not be heavy enough for wet bulb temps to be realized. Thus, expecting mainly light rain now but will have to watch if heavier precip rotates westward.

LONG TERM /THURSDAY THROUGH TUESDAY/. Highlights .

* Near to below normal temperatures through Saturday night, the near to above normal temperatures into early next week

* Periods of showers developing sometime late Wednesday night into Friday

* Dry Saturday, then spotty showers with another weak disturbance Sunday

* Mainly dry conditions Saturday through Tuesday, expect for some scattered showers possible with a cold front passage Sunday into Sunday night

Details .

Mid level flow not expected to evolve too much through the end of this week. Still thinking southern New England will be under the influence of a persistent cutoff meandering between the Great Lakes and the North Atlantic. This pocket of colder air aloft will maintain some instability where showers will result at times. This cutoff should finally move far enough away from our region towards Saturday. Expecting the weather pattern to be more progressive as we head into early next week.

At the surface, expecting an offshore low pressure to retrograde back to the west Thursday night into Friday. While this low should remain over the North Atlantic, it should get close enough to produce a period of showers, especially across eastern MA. Depending upon the exact timing, which is not yet known, there is a risk for some wet snowflakes across the higher terrain of central and western MA Thursday night.

With a high pressure farther to the north, the pressure gradient increases. Could be quite gusty towards the coasts during this time, too.

As this low pressure moves farther away Friday into Saturday, looking at a drying trend. Winds will diminish Friday night, but will remain onshore so could see a few isolated showers lingering across Cape Cod and the islands. High pressure then passes by Saturday, with another cold front sweeping across our region Sunday. We should return to the influence of a high pressure early next week.

AVIATION /00Z WEDNESDAY THROUGH SUNDAY/. Forecaster Confidence Levels .

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

Tonight . High confidence in trends. Lower confidence on exacting timing.

Mainly VFR this evening. MVFR conditions more likely after 01/06Z across the Cape and islands. Eventually, expecting MVFR conditions to develop along the east coast, including KBOS. Likely in place for the morning push.

Wednesday . Moderate confidence. Some uncertainty how far inland MVFR cigs will track.

MVFR cigs over southeast MA, including Cape Cod and Islands. VFR elsewhere. N wind gusts 25-30 kt developing in the afternoon over Cape/Islands.

Wednesday night . Moderate confidence. Some uncertainty how far inland MVFR cigs and showers will track.

MVFR likely along eastern MA coast with possible light rain/snow showers. VFR cigs likely farther inland with dry weather.

KBOS Terminal . High confidence in TAF through most of tonight. Uncertainty on arrival time and duration of MVFR conditions during the morning.

KBDL Terminal . High confidence in trends, but lower confidence on exact timing.

Outlook /Thursday through Sunday/ .

Thursday: MVFR/IFR conditions possible. Windy with gusts up to 30 kt. Chance SHRA.

Thursday Night: Mainly MVFR, with areas IFR possible. Windy with gusts up to 35 kt. Chance SHRA, patchy FG.

Friday: MVFR/IFR conditions possible. Windy with gusts up to 35 kt. Slight chance SHRA.

Saturday: Mainly VFR, with areas MVFR possible. Breezy.

Saturday Night: VFR.

Sunday: Mainly VFR, with local MVFR possible. Chance SHRA.

MARINE. Tonight . Modest NNE wind 10-15 kt with gusts up to 20 kt. Seas 5-8 ft across the outer waters given long NE fetch. Mainly dry weather and good vsby.

Wednesday . Low pres emerges off the NC coast and moves ENE well south of New England. However NE winds increase to 20-25 kt late in the day. Seas build as well along with some light spotty rain.

Wednesday night . Low pres intensifies as it tracks well southeast of 40N/70W then into southeast Georges Bank. NNE winds increase 20-30 kt along with vsby reduced in rain.

Outlook /Thursday through Sunday/ .

Thursday: Low risk for gale force winds with gusts up to 35 kt. Rough seas up to 12 ft. Rain showers likely, patchy fog. Local visibility 1 nm or less.
