Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 358 AM EST Mon Mar 8 2021

SYNOPSIS. High pressure will continue to build overhead today, before shifting offshore during the middle of the week. A cold front will approach from the north and then pass through the area toward the end of the week.

NEAR TERM /THROUGH TONIGHT/. As of 3 AM, temperatures have dropped back into the upper teens to 20s across the area, with mostly clear skies and calm winds in place. Current satellite imagery shows some high clouds across West Virginia. These high clouds should progress eastward over the next several hours. As a result, there may be some high clouds present around sunrise. These high clouds should quickly press off to the east, giving way to mostly sunny skies as high pressure builds directly overhead. Temperatures should rebound quickly beneath mostly sunny skies after a chilly start to the morning. High temperatures today should reach into the 50s for most, with some lower 60s possible across central Virginia.

High pressure will settle to our south and east tonight, leading to another night with mostly clear skies and light winds. Lows overnight will be warmer than preceding nights, with most locations bottoming out in the 30s (around 40 in downtown DC and Baltimore).

SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/. Our stretch of quiet weather conditions will continue through mid- week. High pressure will shift offshore and flow aloft will become zonal in nature. A weak disturbance embedded in zonal flow will pass through Tuesday Night, but won't produce anything more than some high clouds. Otherwise, mostly sunny skies are forecast for both Tuesday and Wednesday. A notable warming trend will occur as warmer air advects into the region on the back side of the high. High temperatures will make it well into the 60s across the area on Tuesday, and could even make a run at 70 across the southeastern half of the forecast area. Temperatures should be even a few degrees warmer on Wednesday, with highs in the upper 60s and lower 70s for most. With relatively dry air in place, and mainly clear skies, temperatures will still be able to drop back into the 30s and lower 40s Tuesday night. Wednesday night will be a bit warmer, with lows in the 40s.

LONG TERM /WEDNESDAY THROUGH SUNDAY/. High pressure will be offshore Thursday, with low pressure near the Canadian Maritimes and a trailing cold front across the Great Lakes. As the jet stream shifts southward, some additional mid and high level cloudiness can be expected, but gusty southwesterly surface winds will help much of the area reach well into the 60s to mid 70s . around 20 degrees above normal.

The front will slowly settle toward the area Thursday night into Friday. With the primary upper level forcing departing well to the northeast and a westerly/downsloping component to the low level winds, precipitation could be difficult to come by east of the mountains. Cold advection likely will hold off through the day as well, so most areas will reach the 60s and 70s again.

The front will stall near or just south of the area Friday night into Saturday. A wave of low pressure may track along the front Saturday, which could bring a better chance of rain, though the exact placement is still in question. Temperatures will be a little cooler, though they should remain above normal.

The front may push south by Sunday as strong high pressure builds over the Great Lakes. This would result in a dry day with near normal temperatures. However, ensembles show the front could still linger nearby, so some small chances of rain remain in the forecast.

AVIATION /09Z MONDAY THROUGH FRIDAY/. VFR conditions and light winds are expected at the terminals through Wednesday. Winds will be predominantly out of the west today into tomorrow, before turning more southerly on Wednesday.

VFR conditions expected Thursday and Friday. Southwest winds could gust above 20kt at times Thursday. A cold front will approach Friday, but precipitation chances are limited.

MARINE. Predominantly sub-SCA level winds are expected over the waters through Wednesday. Winds will be westerly today into tomorrow, before turning southerly on Wednesday. Winds may also be southerly for a brief time tonight. Channeling could lead to marginal SCA conditions on the Bay by Wednesday night.

Southwesterly flow continues Thursday. Marginal SCA conditions are possible, though very warm air over the colder waters will likely inhibit efficient mixing of stronger winds aloft. A cold front will approach Friday, and winds should lessen a bit as high pressure moves farther away.

FIRE WEATHER. A dry airmass will remain in place through the middle of the week. Relative humidity values could reach the 20s and 30s (and possibly teens this afternoon) over portions of the area each day through Wednesday, but winds will generally be less than 15 mph. While critical fire weather conditions are unlikely, the continued sunshine, low humidity, increasing temperatures, and daily breezes will help fuels continue to dry out. Winds may be a little stronger Thursday, though humidity will also be increasing.
