000 FXUS61 KBOX 010812 AFDBOX Area Forecast Discussion National Weather Service Boston/Norton MA 412 AM EDT Wed Apr 1 2020 .SYNOPSIS... Mainly dry and cool conditions today as northerly flow continues. A large ocean storm will track well southeast of New England tonight then stall into Friday. This storm will bring occasional rain to eastern and southeast New England, strong winds over the Cape/Islands and potential for minor coastal flooding along east coastal Massachusetts. 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 PM THIS EVENING/... Strong ocean storm moves east off the NC coast today with deep moisture remaining to the south. However, as the storm deepens the western extent of the deep moisture plume may back into the Cape/Islands with risk for some light rain here late in the day. Otherwise, dry weather. N/NE flow will result in increasing low level moisture which will back in across eastern New Eng. This will bring lots of clouds to eastern MA into RI with more sunshine further to the west, especially into the CT valley. Another chilly day with temps several degrees below normal, ranging from lower 40s across eastern MA to near 50 in the CT valley. Strengthening N/NE flow as storm deepens to the south with gusts 25-30 mph developing this afternoon over the Cape/Islands. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/... Tonight... Sub 980 mb low tracks well SE/E of the 40N/70W benchmark. However, large circulation with developing warm advection and deep moisture wrapping to the west will result in some light rain backing in across the Cape/Islands this evening and possibly into eastern MA overnight. Much of the rest of SNE expected to remain dry. Increasing N winds along the coast, with gusts 35-45 mph developing overnight outer Cape/ACK with 25-30 mph along the immediate coast. Thursday... Ocean storm expected to stall well east of the benchmark in response to strong downstream blocking over the north Atlantic. Deep moisture plume and a well defined TROWAL will rotate westward into New Eng. This will bring periods of rain to eastern MA which is expected to gradually push west through SNE in the afternoon. Low level temp profile warm enough to support rain in the higher elevations. Gusty northerly winds expected with gusts 35-45 mph Cape/Islands with a risk for 50 mph over ACK where wind advisories may be needed. 25-35 mph gusts expected elsewhere. Highs mostly in the 40s, to near 50 in the lower CT valley which will be dry into the afternoon. && .LONG TERM /THURSDAY NIGHT 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 /08Z WEDNESDAY THROUGH SUNDAY/... Forecaster Confidence Levels... Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. Through 12z... MVFR cigs Cape/Islands spreading inland across SE MA, otherwise mainly VFR.
