Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 930 PM EDT Sun Sep 19 2021

SYNOPSIS. High pressure over northern New England will maintain a surface ridge into the area through Tuesday morning. A strong cold front will pass through the area later Wednesday into Thursday and Canadian high pressure will build overhead late next week.

NEAR TERM /THROUGH MONDAY/. High pressure at the surface is currently centered over northern New England, while an upper level ridge is located overhead. As a result, quiet weather conditions are expected overnight. Some high clouds are starting to stream in from the west, and some low clouds and/or fog may form later tonight, especially across southwestern portions of the forecast area. Lows tonight will be in the upper 50s to middle 60s for most.

SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/. Areas of stratus and/or fog along with some light rain or drizzle will be possible each morning due to onshore/easterly flow on the south side of high pressure system offshore the New England coast. By Tue night, flow strengthens and becomes more southerly with warm moist air advection into the region ahead of deepening trof over the mid MS Valley. Latest model trends indicate a much slower progression of upper trof and associated sfc front across the area mid week. Expect bulk of the rainfall to occur late Wed night and Thu.

LONG TERM /WEDNESDAY THROUGH SUNDAY/. Large upper level trough will continue to migrate towards the region late Tuesday night in Wednesday with an associated cold front being the main feature of concern for our area. Guidance has begun to agree on a slightly slower solution to the frontal passage for a late Wednesday into Thursday timeframe. Initial cloud cover and showers are expected to start sometime later Tuesday ahead of the front and may bring some moisture for the western portions of the CWA that evening. With this feature ahead of it bringing in some cloudier skies along with keeping dewpoints in the upper 60s should continue for now to alleviate the convective potential for this system. Bulk shear values continue to be fairly high across the area (40-45 kts) but CAPE continues to persist as being low for the time period (100-200 j/kg). May see a hydro threat with some probs of >2.0" PWATs for Wednesday afternoon into Thursday in place across the I-95 corridor. Still a number of days out so will need to continue to monitor this system as we get closer to the event.

Most models have most of the moisture out of the area overnight Thursday with only a few lingering showers across the I-95 corridor. This trough and frontal passage will bring a large area of cooler weather with highs dropping into the low to mid 70s on Friday and on through the weekend with high pressure building in from the SW. Large upper low may sag down far enough late in the weekend to bring some showers across portions of the area late Saturday into Sunday but no hazardous weather expected at this time.

AVIATION /01Z MONDAY THROUGH FRIDAY/. VFR conditions are expected tonight through tomorrow, although some low clouds or fog can't be ruled out at CHO tonight. VFR conditions will continue tomorrow. Conditions may drop to sub- VFR in association with low clouds both tomorrow night and Tuesday night.

Sub-VFR condtions expected Wednesday and Thursday with a strong cold front passing through much of the day on Wednesday and well into Thursday. VFR conditions should return from west to east starting around midday on Thursday as the cold front pushes through with MRB/CHO most likely clearing out first.

MARINE. Winds have diminished for the time being, but are forecast to strengthen again Mon afternoon and remain gusty through mid week. New SCAs have been issued for Mon afternoon and night.

Marine hazards expected for Wednesday and Thursday as a strong cold front impacts the waters with the possibility for Gale Warning criteria to be met.

TIDES/COASTAL FLOODING. Water levels begin to rise again Monday as onshore flow strengthens around high pressure system offshore of the New England coast. Minor coastal flooding will be possible beginning Monday and continuing through mid week.
