Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 947 PM EDT Thu Apr 9 2020

SYNOPSIS. A cold front will exit to the east overnight while low pressure deepens near Maine. The strong low will remain nearly stationary through Friday, then high pressure will be able to build overhead Saturday. Low pressure will affect the area Sunday into Monday. High pressure builds back into our region through the middle parts of next week.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. As low pressure deepens and slows down near Maine, low level wind fields will remain strong through the night. Should be below advisory levels (except perhaps on the ridges), but elevated gusts will likely continue through the night. Vorticity rotating around a closed upper low to our north may result in a few showers across northern areas through this evening. Snow showers (and perhaps squalls) will be found along the Allegheny Front, although accumulations should generally remain below advisory criteria. Cold advection will result in lows in the 30s to lower 40s.

SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/. The low will remain nearly stationary near the Canadian Maritimes through Friday while high pressure attempts to build in from the west. This will keep a tight pressure gradient across our area, so winds should increase again after sunrise. Based on latest guidance, issued a wind advisory for northeastern quadrant of CWA, and it may need extension further southwest. Upslope snow showers will begin to diminish as the upper low pivots away. Otherwise expect a mix of clouds and sun with much cooler high temperatures in the 40s to mid 50s.

The gradient winds will continue to weaken Friday evening and into Saturday as the surface low continues to lift northeastward away from our region. As winds become light and cooler air moves into our region, radiational cooling within the already cold air mass will bring temps down to near freezing or below across many areas northwest of I-95, so have issued freeze watch. High pressure will be firmly in place over our region Saturday with winds becoming light. Temperatures will be continue to be cooler with daytime temps in the 50s and lower 60s. A warm front will lift north of our area late Saturday night. A lead vort max ahead of the next system may try to produce a shower or sprinkle across western areas, but most areas should remain dry. Temperatures will moderate a bit into the upper 30s to mid 40s.

LONG TERM /SUNDAY THROUGH THURSDAY/. Dry conditions are likely early Sunday with high pressure offshore. However a potent shortwave diving south out of the Texas Panhandle will generate a strong area of low pressure over the Gulf of Mexico. Rain will begin developing Sunday evening as the low tracks northeastward along the Appalachians. Guidance has been very consistent with this system in regards to the abundance of rainfall associated with it. PWAT anamolies based on ensemble guidance continues to remain 2 to 2.5 standard deviations above normal. Ample moisture coupled with strong jet dynamics signal periods of heavy rainfall through the day Monday. Overall, expect a general 1-2 inches of rainfall across the region. In terms of any possible severe weather poised for Monday, confidence remains low at this time given low CAPE values and weak mid-level lapse rates. However given the high shear profile, could be enough to cause locally damaging winds and perhaps a spin up. The best chance for this to occur would be late Sunday night through midday Monday as the low's associated cold front moves through the CWA. On a positive note, this is a quick moving system and most, if not all, precip will cease by Monday night.

Weak high pressure will move overhead for Tuesday, giving us a break in the action. However, the jet stream remains quite active as most of the continental US remains under a longwave trough. Model guidance begins to diverge after Tuesday in regards to another shortwave pulse that could generate another low over the Gulf of Mexico. The ECMWF develops it just to our southeast, which would set us up for a similar situation to Monday's system. However the GFS develops this low further offshore, which would keep our area drier. In any case, expect the long term pattern to remain unsettled, with cooler than normal temperatures developing after Monday through the end of next week.

AVIATION /02Z FRIDAY THROUGH TUESDAY/. VFR overnight, though while winds diminish some, some 20-30 kt gust will remain likely.

Strong westerly winds will continue into Friday with gusts of 25 to 40 knots possible. Winds are expected to slowly taper off Friday evening and into Saturday. No flight restrictions are expected Friday and Saturday.

VFR conditions are likely early Sunday before CIG/VSBY restrictions ensue by Sunday evening as rain develops across the region. IFR/LIFR conditions are likely Monday with periods of heavy rain and possible thunderstorms. Low-level wind shear is also of concern given a very strong wind field aloft. Gusty winds are also likely and even damaging winds cannot be ruled out at this time. Conditions are likely to improve by Monday evening as the low quickly moves away from the terminals.

MARINE. Generally SCA winds expected overnight, but will increase again after sunrise. Have issued new Gale for all waters during the day, then SCA through Friday night. Winds diminishing Saturday as high pressure builds overhead.

Low pressure will track northeastward Sunday evening into Monday. Gusty south to southeast winds are likely, with the strongest winds most likely Sunday night into Monday morning. Periods of heavy rain and perhaps even a couple thunderstorms are expected. Gusty to damaging winds are possible in any thunderstorms that develop. A brief waterspout is possible as well, given a very strong wind field aloft. Confidence for this to occur is low at this time.

FIRE WEATHER. Strong winds and low humidity are expected along and east of the I-95/US 29 corridor in Maryland and Virginia on Friday. Have issued SPS through 6 PM to highlight this fire danger threat.
