SYNOPSIS
A dry cold front moves offshore tonight, ushering in the coldest airmass of the season today into Wednesday. Temperatures moderate late week into the weekend with the next chance for rain arriving Friday and again Sunday into Monday.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/
As of 300 PM EST Tuesday...

A dry cold front is crossing the Mid-Atlantic this afternoon, bringing gusty winds and drier air. Behind it, high pressure builds in from the W. Aloft, A strong trough is situated over the East Coast with its axis cutting through the local area. Latest obs show temps in the low 40s in northern counties and mid-upper 40s in the S of I-64. The western edge of counties (behind the front) have dewpoints that have dropped into the single digits. Elsewhere, dewpoints are in the teens. Winds are gusting 25-30mph. As such, wind chills are in the 30s to around 40. Latest satellite shows scattered to broken cloud cover E of I-95 ahead of the front. There are some light echos on radar over the Eastern Shore. Cannot rule out a couple of flurries making it to the surface, but should not be significant.

The cold front will push offshore this evening and cold, dry air will fill in behind it. Skies will clear out and winds will diminish as the high builds in. The CAA combined with decent radiative conditions will allow for the coldest night of the season so far.
Lows will be in the teens for much of the area, especially W of I- 95. Along the immediate coast, winds should remain elevated enough (~10mph) to keep temps in the mid-upper 20s. The record lows for tonight have been included in the Climate Section below, though it is unlikely the records will be challenged at RIC and SBY.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/
As of 300 PM EST Tuesday...

Winds become SW ~10 mph Wednesday with gusts to 15-20 mph and highs in the mid 40s most places. This will once again keep wind chills cold all day with afternoon wind chills in the upper 30s to around 40F. Lows Wednesday night/Thursday morning will be warmer compared to the previous night but still cold in the mid- upper 20s inland and upper 20s/lower 30s in urban areas and along the coast. High pressure remains in control of our weather pattern (centered just south of the local area) during the day on Thursday. Temperatures moderate Thursday afternoon into the mid to upper 50s for much of the area due to southwest flow at the surface and ridging developing aloft. Partly-mostly sunny with just some high clouds. Partly cloudy, with increasing clouds Thu night and lows in the low-mid 30s for most, around 40 near the coast.

The center of high pressure will be well offshore by Friday morning. Meanwhile, low pressure will be tracking ENE from the the mid MS Valley into the midwest by aftn. Rain chances increase from west to east during the day on Friday with the highest chances area wide likely during the afternoon/evening hours. The trough aloft looks to dampen with time as it reaches the Appalachians later Friday, so even with a period of likely PoPs Fri aftn into Fri evening, QPF amounts are not expected to be a lot, generally around 0.10". It will be mild Friday with highs ranging from the lower 50s NW to the low 60s SE.

LONG TERM /FRIDAY NIGHT THROUGH MONDAY/
As of 300 PM EST Tuesday...

A cold front moves through the region Friday night, bringing an end to any remaining precipitation for most of the region, though the trend is for the front to stall just S of the CWA on Saturday. Past Friday night, uncertainty increases as global models disagree whether or not a secondary low pressure forms and if it will pass over the area or offshore. Either way, the pattern does look unsettled with multiple chances for rain through Monday. For now, sticking close to the blended guidance.
Saturday morning will likely be dry, then Schc-chc PoPs stick around Saturday evening through Monday afternoon. Highs on Saturday-Monday will range from the low-mid 60s in the SE to the mid-upper 50s in the NW. Lows will be in the 40s for most and low 50s in the far SE.



AVIATION /20Z TUESDAY THROUGH SUNDAY/
As of 1255 PM EST Tuesday...

VFR conditions are expected through the 18z/28 TAF period.

SCT-BKN cloud cover will clear out through the evening as a cold front crossing the region pushes offshore. Behind the front, winds are turning to the NW and gusting 25-30kt. These will diminish overnight as high pressure builds in, though gustiness will linger near the coast through the first part of tonight.
Winds turn to the SW early tomorrow morning, starting out light, then increasing to 5-10kt in the afternoon.

Outlook: High pressure becomes centered S of the region Wed through Thursday, bringing dry WX and VFR conditions. Winds shift around to the SW and will average around 10 kt both days.
The next chance for rain (and flight restrictions) will be Friday, then drying out Saturday.

MARINE
As of 300 PM EST Tuesday...

A vigorous upper trough is pushing off the coast this aftn with strong cold/dry advection in its wake. The wind is generally WNW 20-25kt with gusts up to 30kt, and 25-30kt with gusts to 35kt offshore N of Parramore Is. Seas are mainly 4-5ft offshore with waves in the Bay of 3-4ft. High pressure builds in from the NW late this aftn and evening behind the upper trough, and then settles immediately inland of the Southeast and southern Mid-Atlantic coasts by early Wednesday morning. The wind will maintain its current intensity through the evening, before diminishing overnight as the pressure gradient slackens. Gale warnings remain in effect through 1 AM N of Parramore Is., with SCAs for the upper rivers, Currituck Sound and ocean S of the VA/NC border through 1 AM, and SCAs for the Bay, lower James, and ocean from the VA/NC border through Parramore Is. through 4 AM.

High pressure slides across the coast Wednesday morning, and then settles off the coast by Wednesday aftn and Wednesday night. A SW wind is expected to increase to 15-20kt with gusts to 25kt across the Bay/northern ocean by Wednesday evening, with SW 10-15kt with gusts up to 20kt elsewhere. SCAs are possible for the Bay during this time period. High pressure lingers near the coast Thursday into early Friday, then a weak low pressure system slides across the coast later Friday into Saturday. Sub-SCA conditions are expected during this time period.
