It turns slightly milder today with increasing clouds as a warm front approaches the area from our southwest and there can be a late day shower or two. Showers are likely tonight as the warm front pushes through the region and temperatures will surge on Saturday to near 80 degrees for afternoon highs. There should be some sunshine to go along with the warmth on Saturday and a stiff breeze as well from a west-to-southwest direction. This surge in temperatures in the Mid-Atlantic region will become somewhat muted on Sunday as clouds will dominate the skies and help to knock temperatures down some from tomorrow’s high levels and there will be an increasing chance of showers later in the weekend. Looking ahead, a strong storm will pass by to the northwest of the Mid-Atlantic’s I-95 corridor region on Monday and it’ll drag a strong cold front through the area with additional shower activity and perhaps a strong thunderstorm. This frontal passage will end the warm spell leading to much colder conditions by Tuesday and its stays on the chilly side next Wednesday as well.

Any long-time weather forecaster in the northeastern part of the nation knows quite well to be fearful of the “back door” cool front this time of year as it can make a forecast of summer-like temperatures look rather foolish with winter-like reality instead. Indeed, the “back door” cool front is rather common in the northeastern part of the US during the months of March and April, and it can mean the difference of 30-40 degrees over a short distance, and the difference between summer and winter weather conditions over a short period of time.
In fact, there can be winter-like temperatures this Saturday in Boston, Massachusetts while a summer-like feel is as close by as Harford, Connecticut, and summer-like temperatures in New York City on Saturday can drop significantly by Sunday after the passage of a “back door” cool front from northeast-to-southwest. The key factor in the potential dramatic impact of the passage of a “back door” cool front this time of year is that the western Atlantic Ocean is still quite cold so a switch of low-level flow of air from a warmer continental direction to an ocean flow can result in substantial temperature swings.

It becomes breezy today and stays on the cool side despite plenty of sunshine with afternoon high temperatures in the low-to-mid 50’s. It turns slightly milder on Friday with increasing clouds and then a warm front pushes through on Friday night likely accompanied by some shower activity. Following the passage of the warm front, temperatures should surge on Saturday to well up in the 70’s and there should be some sunshine and a stiff breeze. This surge in temperatures in the Mid-Atlantic region will be muted somewhat on Sunday as clouds will become dominate and help to knock temperatures down some from Saturday’s warmth and there will be an increasing chance of showers later in the weekend. Looking ahead, a strong storm will pass by to the northwest of the Mid-Atlantic’s I-95 corridor region on Monday and it’ll drag a strong cold front through the area with additional shower activity. This frontal passage will end the warm spell in a hurry leading to much colder-than-normal conditions by Tuesday, April 1st, and it stays on the cool side for next Wednesday as well.

The “boys of summer” are back in town...big-league baseball gets underway on Thursday with home openers in New York City (Yankees vs. Brewers) and Washington, D.C. (Nationals vs Phillies) where there should be loads of sunshine and dry, cool conditions. High pressure will be in control of the weather in the Mid-Atlantic region on Thursday resulting in the dry, cool conditions with highs likely in the lower 50’s across New York City and the upper 50’s in the D.C. metro. After a warm frontal passage on Friday night, a major-league warmup is coming on Saturday with 80 degrees on the table in at least parts of the Mid-Atlantic region.

A cold frontal system will push through the region this morning and there can be a rain and/or snow shower associated with it followed by some clearing skies during the afternoon. It’ll be on the breezy and cool side both today and tomorrow with temperatures below-normal for this time of year. A warm front arrives on Friday night with some shower activity likely and its passage will usher in a much warmer air mass for the upcoming weekend. Temperatures on Saturday could soar well up into the 70’s and should remain quite mild on Sunday and Monday as well with a late weekend chance of showers.

High pressure takes control of the weather today on the back side of a departing cold frontal system and it should result in some sunshine and a breezy, milder afternoon. A weak disturbance slides to our south early tomorrow and then high pressure returns for later tomorrow and Thursday. It’ll be on the cool side on both Wednesday and Thursday and then milder weather returns for the end of the week and upcoming weekend; however, it’ll become more unsettled as well with an increasing chance of showers.

The week starts off unsettled as a cold frontal system slowly works its way through the area producing occasional showers right through early afternoon. High pressure will take control on Tuesday, but only for a brief time as another system can produce some shower activity around here on Tuesday night and Wednesday morning. The weather returns to generally dry and cool conditions for later Wednesday and Thursday as another high pressure system builds into the region.

Winds will be quite strong today from a northwesterly direction and can gust to 40 mph or so on the back side of a cold frontal system. High pressure takes control providing us with some sunshine to go along with the windy and chilly conditions as we close out the work week. A weak cold front can produce a shower or two on Saturday and it’ll turn somewhat cooler and breezy on Sunday ahead of the next cold front which can produce showers around here on Sunday night and Monday.

An on-going stratospheric warming event that began in late February increases the chance for additional cold air outbreaks as we wind down the month of March from the Great Lakes/Midwest to the Mid-Atlantic/Northeast US. In fact, the typical lag time between a stratospheric warming event over the polar region and its impact on US temperature patterns suggests there may very well be cold air outbreaks to deal with in this part of the country at least until the middle of April. As it turns out, big-league baseball gets underway in earnest in one week’s time on Thursday, March 27th, and the early part of the season may feature plenty of cold weather games thanks in large part to the on-going big-league stratospheric warming event. In addition, the influx of colder-than-normal air masses in coming weeks keeps hope alive across the northern states for those wishing for more snow...yes, even though spring season is now officially underway.

A strong cold front will head this way today from the Ohio Valley and it’ll help to spawn the formation of low pressure near the Mid-Atlantic coastline by later tonight. The combination of the low pressure system and cold front will bring rain to the region from late today into tonight and winds will kick up as well. In fact, those winds can gust to 40 mph or so by late tonight and through the day on Friday which will be a cooler day compared to today. A weak front can bring some clouds to the area on Saturday and perhaps a shower or two, and then it turns cooler on its heels to close out the upcoming weekend. Another cold frontal system can bring more rain to the area by the early part of next week.
