SYNOPSIS
A cold front moves through late tonight through Wednesday. High pressure builds in again Thursday into Friday. A warm front moves through over the weekend.

NEAR TERM /THROUGH TONIGHT/
A cold front approaches from the west tonight. Southerly flow and increasing clouds ahead of this front will keep low temps well into the upper 40s to low 50s. A few showers are possible with the frontal passage, mainly prior to sunrise Wednesday morning.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/
Showers continue over the Alleghenies through Wednesday morning with upslope flow, and more showers develop along central Maryland and along the Chesapeake Bay as the front advances eastward. A few rumbles of thunder can't be ruled out in the afternoon. Showers exit by the evening. Patchy frost could develop Wednesday night depending on how much clearing occurs behind the cold front, but we'll continue to evaluate.

Dry conditions return Thursday with high pressure building into the region.

Temperatures on Wednesday will depend on the timing of the cold frontal passage as temps drop behind it, but could see above normal temps in the low 70s east of the Blue Ridge before the front passes in the afternoon. Thursday will be cooler with highs in 50s and 60s.

LONG TERM /FRIDAY THROUGH TUESDAY/
The long term period will start out dry as upper level ridging shifts over the area throughout the day on Friday. At the surface, high pressure shifts southeast over the Atlantic throughout the period. High temperatures on Friday will get into the 60s for most with highest ridgetops staying in the 50s. Overnight lows will dip into the 40s areawide. Starting Friday night into Saturday, precipitation chances increase west of the Blue Ridge as a low pressure system moves over the Great Lakes region. Dry air aloft will keep rain chances less than 50% with conditions drying out overnight Saturday into Sunday. Isolated to scattered rain showers cannot be ruled out Monday afternoon as a frontal system approaches the area.

As upper level ridging builds overhead and return flow ushers in warm air, temperatures noticeably warm on Sunday. High temperatures on will be in the mid 70s to 80s for most with higher elevations staying in the upper 60s. For Monday, high temperatures rise into the upper 70s to 80s areawide. Overnight low temperatures will be in the upper 50s to mid 60s both nights.

AVIATION /01Z WEDNESDAY THROUGH SUNDAY/
VFR conditions are expected through the TAF period. Some isolated to scattered showers could bring brief reductions tonight into Wednesday. Have introduced some showers into the TAFs early in the morning given recent trends in guidance.

Winds will diminish this evening, however, a decent LLJ develops around NE MD overnight. Keeping LLWS in the BWI and MTN TAFs as a result.

Winds pick up out of the northwest on Wednesday with gusts around 20-25 kt possible. Northeasterly flow and dry conditions arrive Thursday.

VFR conditions are expected Friday at all terminals with high pressure overhead. On Saturday, a frontal system passing to our west will bring low end rain chances to MRB with the rest of the terminals staying dry. Southeast winds on Friday shift to southerly on Sunday, blowing around 10 knots and gusting 15-20 knots each afternoon.

MARINE
Small Craft Advisories remain in effect for all waters through Wednesday morning. After that, winds may experience a bit of a lull in the afternoon. Winds pick up again as they turn northerly and channel down the Chesapeake Bay.

SCA criteria winds could continue into Wednesday afternoon.
Winds over the waters diminish and turn out of the northeast on Thursday.

Southeast winds on Friday shift to southerly on Saturday with dry conditions expected over the waters both days. Winds will be right below SCA criteria on Friday before diminishing overnight into Saturday morning. Winds pick up again on Saturday and will likely reach SCA criteria in the afternoon.

FIRE WEATHER
RHs recover tonight to 60-70% with some reduction in winds.
Winds turn out of the northwest behind a cold front and will be stronger, sustained around 15-20 mph and gusts 20-25 mph and possibly higher along the ridges. RHs could drop into the upper 20s and low 30s on Wednesday afternoon. Will continue to monitor conditions going into Wednesday, especially with regards to any rainfall that may occur tonight.

TIDES/COASTAL FLOODING
Tidal anomalies continue to increase under southerly flow. Minor coastal flooding is expected for Annapolis for Wednesday morning's high tide, and a Coastal Flood Advisory has been issued. Minor flooding is also possible at Straits Point and Havre De Grace.
Otherwise only Action stage is anticipated for the remaining tidal sites. Winds turn out of the northwest on Wednesday resulting in lowering tidal anomalies.
