...UPDATED National Weather Service Baltimore MD/Washington DC
1023am EDT Thu Mar 30 2023

High pressure returns to the area today. An area of low pressure will impact portions of the Mid-Atlantic Friday into Saturday, bringing widespread rainfall and high winds. Behind it, high pressure builds back in for the end of the weekend and into early next week.

Near Term - Through Tonight
Fair weather today under high pressure. Winds are on the downward trend since last night. Temperatures will be about 5 degs cooler than yesterday, generally in the mid 50s. Increasing cloud cover overnight may hinder frost formation. Will reevaluate frost potential later.

Short Term - Friday Through Saturday Night
By Friday, a warm front is expected to lift northward as an associated low pressure system continues to move further east from the northern plains and Great Lakes region. Shower chances likely begin to increase late Friday morning and into the early afternoon before a low-level jet pushes into the region. Temperatures as a result of warm air advection will climb into the upper 60s to near 70F closer to the I-95 corridor, with 50s across the higher elevations. Quantitative Precipitation Forecast looks to be remain fairly low for the day, as the main moisture plume will be off to the north and west closer to the center of low pressure. Winds will likely pick up later in the afternoon and early evening on Friday, with some areas out west gusting to 25 to 35 mph. These winds will continue to pick up into the start of the weekend.

By Saturday, precipitation will likely continue to stick around through a portion of the day as the low pressure center continues to move further north and east. A strong, potent cold front will approach the region. A very tight pressure gradient as a result of the low pressure system and cold front passage will bring the opportunity for damaging wind gusts on Saturday. Wind gusts across the higher elevations out west may gust to over 60-65 mph later Saturday. A High Wind Watch is in effect for portions of the Allegheny Front Saturday morning through Saturday night. There is a non-zero chance for a strong thunderstorm Saturday afternoon given increased instability and very strong shear parameters. Highs for the day will soar into the mid to upper 70s closer to the I-95 corridor, with 50s and 60s across the higher elevations.

Long Term - Sunday Through Wednesday
High pressure will build into the region Sunday. Northwest winds will continue to diminish through the day and allow for drier air to push into the region Sunday through Monday with some sunshine each day. Temperatures will be about 20 degrees cooler on Sunday than on Saturday, but should still be rather average for early April with highs in the middle 50s. A cool night in store Sunday night with lows reaching the middle 30s in most places.

High pressure will move east on Monday to allow for a return flow to develop and bring in warmer air from the south once again. Highs on Monday will reach the lower 70s with milder nighttime temperatures expected Monday night with lows in the lower 50s. There is a chance for a few rain showers late Monday into Monday night, mainly along the Mason-Dixon region and in the mountains as a front is not too far away from this region.

A low pressure system could scoot by to our south on Tuesday or perhaps hug the Mason-Dixon region Tuesday night into Wednesday. Additional rain showers possible. Temperatures will once again reach the 70s and perhaps 80s. However, if the front adjacent to our northern zones falls a little farther south then we could have a decent gradient of temperatures with highs in the 60s in our north and 80s in our south.

Sub-SCA (Small Craft Advisory) conditions return today as high pressure builds over the region.

A strong area of low pressure approaches the area on Friday, and a warm front lifts north through the waters Friday morning. SCA (Small Craft Advisory) conditions in SW flow may begin as early as late tonight but then become more likely by Friday and Friday night. While gusts could begin approaching gale force Friday night, low level stability caused by occasional rain and very warm air over the cooler waters may limit gusts through this time.

A Gale Watch is in effect for Friday night through Saturday evening. Southwest winds 20 to 25 knots with gusts up to 40 knots are expected.

Small craft advisories likely Sunday with Gales still possible in the central Chesapeake Bay mainly Sunday morning. Otherwise, no marine hazards Sunday night and Monday morning. Small craft advisories possible once again Monday afternoon and evening, mainly over the northern Chesapeake Bay and near the Tidal Potomac portion of the Chesapeake Bay. Winds northwest 10 to 20 knots gusts 25 knots Sunday, possibly higher in the central Chesapeake Bay. winds diminishing and becoming northeast then southeast 5 to 10 knots Sunday night and Monday morning. Winds becoming south to southwest 10 to 15 knots gusts up to 20 knots Monday afternoon and evening.

Fire Weather
Winds will be lighter today as high pressure moves in, generally sustained at 10 mph or less except on the ridges. However, a very dry airmass will result in RH values between 15 and 30 percent.

The next chance for wetting rain arrives late Friday afternoon into Saturday. Winds will increase markedly, but so will humidity.
