A cold front pushed through the region last night and its passage has unleashed another colder-than-normal air mass to the Mid-Atlantic region. Temperatures today will be confined to the upper 40’s for afternoon highs and then fall into the upper 20’s for overnight lows. After a chilly day on Friday, rain should develop late tomorrow night and continue into Saturday…some of it can be heavy at times. The culprit of this early weekend soaking rain event will be strong low pressure that moves to a position just off the Mid-Atlantic coastline by early Saturday. Following the storm, another chilly air mass will arrive in the Mid-Atlantic region on Sunday and there will again be a stiff flow of air out of the northwest.

An outbreak of colder-than-normal air in the Mid-Atlantic region earlier this week will be followed up by a second shot that arrives on Wednesday night following the passage of a strong cold frontal system. The approaching strong cold front will produce some rain shower activity in the southern Mid-Atlantic region and it is likely to be just cold enough for snow showers and perhaps even heavier snow squalls across upstate Pennsylvania and interior New York State. Following the passage of the front, temperatures will drop into the 20’s late Wednesday night and again late Thursday night…even in the immediate I-95 corridor region.
The cold air mass sticks around into the day on Friday and then attention will turn to a developing low pressure system that is likely to intensify as it pushes to a position just off the Mid-Atlantic coastline by early Saturday morning. As a result, a heavy rain event is likely from late Friday night into Saturday from the I-95 corridor region to the coast. In fact, there is the possibility for as much as 2-4 inches of rain during the early part of the weekend in the DC-to-Philly-to-NYC corridor…watch out for localized flooding. Farther north, the early weekend storm system can bring substantial snowfall of a foot or more to ski country including upstate New York and much of northern New England. On the back side of the storm, winds can become very strong out of the N-NW with gusts possible up to the 40-50 mph range from late Saturday into Sunday and chilly air will push into the northeastern part of the nation.

It becomes quite windy and much milder today ahead of the next cold front and there can be a couple of late day or early evening showers as this system arrives. The passage of the cold front will usher in another colder-than-normal air mass to the Mid-Atlantic region for Thursday and Friday. After that, attention will turn to a strong low pressure system that is likely to push to the Mid-Atlantic coastline by the early part of the weekend and generate some rain around here from late Friday night into Saturday…some of the rain can be heavy. Another colder-than-normal air mass will follow that storm system for the second half of the weekend and the early part of next week.

Colder air pushed into the Mid-Atlantic region on Sunday night following the passage of a cold front and temperatures will remain at slightly below-normal levels around here today. It does turn milder on Wednesday ahead of the next cold front and there can be a couple of late day or early evening showers as it arrives. The passage of that next front will usher in another colder-than-normal air mass for Thursday and Friday and then attention will turn to a possible strong low pressure system that can push to the Mid-Atlantic coastline by the early part of the weekend. One final note, spring officially gets underway later tonight at 11:06 PM.

A cold front passed through the region on Sunday and has ushered in colder air to the Mid-Atlantic region and it’ll stick around through much of the week. Temperatures will generally be confined to the lower or middle 50’s for afternoon highs during the week and can drop to or slightly below the freezing mark in some spots for overnight lows. Strong low pressure may push towards the Mid-Atlantic coastline by the early part of the weekend…something to be monitored over the next few days.
One final note, spring officially gets underway on Tuesday, March 19th at 11:06 PM.

Low pressure will pass by to our north today and drag a frontal system through the region likely generating scattered showers, maybe even an isolated PM thunderstorm. It turns slightly cooler for the weekend, but still warmer-than-normal for the middle of March and there will be plenty of sunshine on both days. Sunday will feature quite a breeze as well ahead of the next front. A noticeably colder air mass pushes into the region by early next week and it will limit daily highs to the 40’s from Monday through Wednesday and overnight low temperatures can drop to below freezing.

Today will be another great weather day in the Mid-Atlantic region with plenty of sunshine, dry and warm conditions, and afternoon high temperatures around here in the mid-to-upper 70’s. It stays very mild on Friday, but there will be the chance of showers and maybe even an afternoon or evening thunderstorm as a cool front pushes through the region. Following the passage of the front, the weekend will turn slightly cooler, but still above normal for the middle of March. A colder-than-normal air mass pushes in for the first half of next week and high temperatures on Monday, Tuesday and Wednesday are likely to peak at 50 degrees or slightly below as compared with the mid-to-upper 70’s expected later today.

From a climatological point of view, March is a favorable time of year for accumulating snow in the Rocky Mountain States and it looks like “climatology” will come through this year. March is also quite an active month on average in terms of severe weather and indeed, an outbreak is possible later tomorrow and tomorrow night across the Mississippi Valley. Meanwhile, the Mid-Atlantic region will enjoy back-to-back-to-back unseasonably warm days featuring temperatures in the 70’s in many spots and spring fever may spread rapidly.

High pressure edged eastward on Tuesday afternoon, and it will slide off the coast today opening the door for unseasonably warm air to our west to move into the Mid-Atlantic region. Temperatures will surge today to near 75 degrees and likely into the middle or upper 70’s on Thursday afternoon. It stays very mild at the end of the work week; however, the pattern becomes more unsettled with a chance of showers on Friday, maybe a thunderstorm. It cools down some this weekend in the Mid-Atlantic region, but still mild for this time of year, and then a colder-than-normal air mass reaches the area for the first half of next week.

After a cold and windy day to start the week, there are big temperature changes on the way for the Mid-Atlantic region beginning today with afternoon highs around here likely in the upper 60’s. The surge in temperatures will continue during the next couple of days with 70 degrees on the table for Wednesday and the middle 70’s on Thursday. It stays quite mild into the late week and weekend, but it'll become more unsettled with the threat of showers on a couple of occasions.
