000 FXUS61 KBOX 231135 AFDBOX Area Forecast Discussion National Weather Service Boston/Norton MA 635 AM EST Thu Jan 23 2020 .SYNOPSIS... High pressure will remain in control through Friday with dry and mild days and a cold night tonight. A storm is expected to impact the region Saturday into Saturday night with mostly rain and gusty coastal winds, but some snow is possible over the higher elevations in northern MA. Mainly dry and seasonable conditions return Sunday lasting into the middle of next week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... 630 AM update... No major changes with this morning's update. Mesoanalysis shows the high pressure moving overhead, with a few high clouds visible on IR satellite. Overall a very nice day to spend outside, with sunny skies, mild temperatures, and light southwest winds. Previous Discussion... Mid level ridge SE of New Eng with anticyclonic flow and very dry air in the column will continue to support mostly sunny skies today. Pronounced low level warming today although subsidence inversion will limit mixing depth. However, sunshine and SW flow with 950 mb temps 3-5C support highs in the mid/upper 40s. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/... Tonight... A weak mid level shortwave approaching from the SW will bring some increase in high clouds. Still decent radiational cooling with light winds yielding lows in the teens in the colder locations and mostly 20s elsewhere. Weak frontal boundary will slip south across SNE after midnight with a wind shift to light north. Friday... Frontal boundary south of New Eng with high pres building to the north will result in low level easterly winds developing. Cross sections show increasing low level moisture from the north with lower clouds developing in the afternoon across northern MA. Otherwise, partly sunny skies. Temps will be a bit cooler due to E/NE winds with highs upper 30s to mid 40s. && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... Highlights... * Dry weather Friday night with above normal temperatures. * Coastal storm this weekend initially bringing a cold rain for much of southern New England. Best opportunity for snowfall is across the highest elevations of the interior where things begin as a wintry mix before transitioning to rain. * Scattered snow showers across the region late on Sunday into early Monday, then dry through mid week. * Slightly cooler temperatures after the weekend. Details... Friday night into Saturday morning... Large surface high remains overhead though on its way out, with a mid level ridge axis crossing New England during this period. This keeps things dry and about 10-15 degrees above normal overnight on S/SE flow in the low levels (+2 to 3 C at 850 mb). Most locations dip into the mid/upper 30s or upper 20s (inland). Average low temps for late Jan are in the teens and low 20s. Winds are light but high clouds should keep us from radiating too well. Saturday and Sunday... Again with the trend, unfortunate for snow lovers, toward the north and west with the track of this weekend's storm system. Signs point more and more to a cold rain for the majority of southern New England on Saturday. Confidence is very high that a soaking storm system arrives over the weekend, while chances of snow outside of the highest elevations are decreasing. A 500 mb trough and surface low will dig into the mid Atlantic on Saturday. A secondary low along the frontal boundary strengthens as it crosses over southern New England (or even potentially northern New England if some of the newest guidance has anything to say about it). Further up at 700 mb where yesterday the low center looked to cross directly over southern New England it now has trended northward, crossing northern New England. As a result, the bulk of the cold air we would need to see more snow is too far north. At the moment the most likely solution on the front end of the event looks to be a cold rain for most, with a rain/snow mix in interior lower elevations, and snow in the highest elevations of the Berkshires and Worcester Hills. Things will then change to rain as the low pulls in warmer low level air and this will continue into the overnight hours. By early overnight hours the dry slot moves into the region and erodes the heaviest rain from the west through the overnight hours so by sunrise most of the precip will have fallen. There is potential for a significant rainfall (QPF values from 1 PM Sat to 7 am Sunday approach 1.25 or 1.5 inches in spots). A few inches of snow in the highest elevations of the Berkshires is possible but totals continue to be lowered. Sunday the low lifts into the Gulf of Maine and colder air will wrap back around the low, but the bulk of the moisture is gone by then so most will stay dry. Some scattered light snow showers are possible; best chance will be the orographically favored western MA/CT. No real accumulation is expected except up to an inch in the Berkshires perhaps. Winds with this system will be gusty, picking up on Saturday afternoon/evening with gusts 25 to 30 mph possible, closer to 40 mph along the southeast coast. Gale headlines may be necessary over the waters where gusts will be even greater. Monday through Wednesday... Drying out Monday and into midweek. The low is slow it exit thanks in part to an area of high pressure off the coast of eastern Canada. However, it eventually moves off and is replaced by high pressure with drier air moving in. We're looking at partly sunny skies for the first half of the work week with cooler temperatures, but still warmer than normal. Monday is the warmest in the low 40s before highs cool a few degrees Tues/Wed. && .AVIATION /12Z THURSDAY THROUGH MONDAY/... Forecaster Confidence Levels... Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. Short Term /through Friday/...High confidence. Through tonight... VFR. SW wind 10 kt or less today becoming light N after midnight. Friday... VFR, but areas of MVFR cigs developing across northern MA in the afternoon. NE wind 10 kt or less. KBOS Terminal...High confidence in TAF. KBDL Terminal...High confidence in TAF. Outlook /Friday Night through Monday/ ... Friday Night: Mainly VFR, with local IFR possible. Breezy. Slight chance FZRA. Saturday: Mainly VFR, with areas IFR possible. Windy with local gusts up to 30 kt. RA, chance SN, slight chance FZRA. Saturday Night: Mainly VFR, with areas IFR possible. Windy with gusts up to 35 kt. Chance RA, chance FZRA. Sunday: Mainly VFR, with local MVFR possible. Breezy. Chance SN, slight chance RA. Sunday Night: Mainly VFR, with local MVFR possible. Breezy. Slight chance SN.
