After a very wet day on Wednesday, high pressure will try to take control today and it’ll become quite warm with afternoon temperatures reaching the 70 degree mark despite plenty of clouds. Low pressure will pass to our west on Friday and it’ll bring a cold front our way generating showers from later tonight into Friday and there can be a thunderstorm or two mixed into the picture. Winds will become very strong as well ahead of the frontal system and can gust to 50 mph early Friday. Behind the front, temperatures will remain quite mild, but they’ll drop some five-to-ten degrees between tomorrow afternoon and Saturday afternoon. Another system is likely to bring us more showers on Sunday and then cooler air moves in early next week.

Last week, the first significant severe weather outbreak of the season so far took place in the Deep South/Tennessee Valley with more than 50 tornadoes recorded and tomorrow may bring a repeat performance in the same general region. On Thursday and Thursday night, there is the potential for an outbreak of severe thunderstorms across states like Mississippi, Alabama and Tennessee and the threat will include large hail, damaging wind gusts and several long-track strong tornadoes. Numerous ingredients will come together on Thursday to generate very strong upward motion in the atmosphere needed for a widespread severe weather outbreak. These ingredients will include a strong low-level jet streak, sharp surface temperature gradient, rapidly strengthening surface low pressure, and an influx of low-level very warm and humid air from the Gulf of Mexico into the Deep South/Tennessee Valley. The severe weather threat will shift into the Ohio Valley by late tomorrow night.

After a couple of dry, mild and quiet days in the Mid-Atlantic region, it’ll turn wet around here today with occasional rain likely as low pressure pushes to our west. After a mostly cloudy and very warm day on Thursday, a cold front will approach the region on Friday bringing with it another chance of showers as we close out the work week and maybe even a thunderstorm. Temperatures ahead of the cold front will surge well up into the 70's on both Thursday afternoon and on Friday, and then they’ll drop by about ten degrees or so for the upcoming weekend following the passage of the front. More rain is looking likely on Sunday in the Mid-Atlantic region.

Today will be another quiet, dry and mild day in the Mid-Atlantic region with plenty of sunshine and highs here well up in the 60’s during the afternoon. Patchy fog is possible late tonight and there can be a couple of showers towards morning and soaking rain is likely during the day on Wednesday as low pressure passes by to our west. After a mostly cloudy day and warm day on Thursday, a cold front will approach the region on Friday bringing with it another chance of showers as we close out the work week. Temperatures ahead of the cold front will surge to the 70's on both Thursday afternoon and on Friday, and they’ll drop by about ten degrees or so for the upcoming weekend following the passage of the front. More rain is looking likely in the Mid-Atlantic region for Sunday.

Today and tomorrow will generally be on the quiet, dry and mild side, but the weather gets a little more active at mid-week and for the late week. Patchy fog is possible late tonight and again late tomorrow night and then a few showers are possible on Wednesday. Late in the week, a cold front will approach the region and bring us another chance of showers as we end the work week.

Low pressure now off the Mid-Atlantic coastline pulled in colder air from the northwest during the overnight hours and the morning will start off with lingering clouds in the I-95 corridor. Drier air will bring some sunshine to the area later today, but it will remain quite windy and much colder-than-normal for this time of year. The weekend will start off on the chilly side, but it’ll turn milder on Sunday and next week looks noticeably warmer than this week.

The month of March has been unusually dry in the Mid-Atlantic region, but a soaking rain event will begin this morning as strong low pressure pushes into the Ohio Valley. This same storm system contributed to the first significant severe weather outbreak of the season on Wednesday and severe weather will be a threat today from Georgia to Virginia. The strong low pressure system will shift in its heretofore northeastward track and take a turn to the south and east later in the day as it runs into an impressive upper-level blocking pattern across southern Canada. At the same time, strong high pressure will build into southeastern Canada today and it will be anchoring quite a cold air mass for this time of year. As the storm pushes to the south and east tonight, the cold air mass will follow suit and rain will change to snow in a northwest-to-southeast fashion. By early tomorrow, low pressure will be situated off the Mid-Atlantic coastline and a mixing with or a changeover to snow is possible all the way down into the DC-to-Philly-to-NYC corridor. After this storm system pushes away later tomorrow, cold and dry air will dominate the scene right through the first half of the upcoming weekend, but it'll turn milder on Sunday.

A very active weather pattern for the eastern half of the nation during the next few days which will include the first significant severe weather outbreak of the season, the first soaking rain event in weeks across the Mid-Atlantic/Northeast US, and a changeover of rain-to-accumulating snow in many areas. Severe thunderstorms later today and tonight in the Deep South/Tennessee Valley will be capable of producing torrential rainfall, large hail, damaging wind gusts and tornadoes. A particularly dangerous situation is likely to develop later today in the Mississippi/Alabama region where numerous ingredients are coming together for high probabilities of severe weather. The severe weather threat will shift eastward to the Carolinas and Virginia on Thursday and continue into early Friday. The same storm system that will be contributing to the severe weather outbreak will result in a soaking rain event for the Mid-Atlantic/Northeast US on Thursday and Thursday night – the first significant rainfall in weeks in many of those locations. As colder air wraps into the low pressure system later tomorrow night, rain will change to snow in a northwest-to-southeast fashion and there can be snow all the way down into the DC-to-Philly-to-NYC corridor by early Friday.

The month of March has been unusually dry in the Mid-Atlantic region, but a soaking rain event will begin on Thursday and continue into early Friday. High pressure takes control again today we’ll have a bit of a warm up compared to the chill of the past couple of days. A strong low pressure system will then push into the Ohio Valley on Thursday and ultimately, to a position off the Mid-Atlantic coastline by early Friday. As a result, rain should push into the area early Thursday and continue off and on into early Friday. As colder air filters in from the northwest, there is a good chance that the rain mixes with or changes to snow by early Friday before the precipitation event winds down in the I-95 corridor. A cold start to the weekend will follow as Canadian high pressure builds back into the northeastern quadrant of the nation. Looking ahead, warmer weather returns early next week with highs back up in the 60's.

It has been an unusually dry month of March so far in the Mid-Atlantic region with zero precipitation reported in DC, Philly and NYC. The impact of the dry spell has actually been made worse with an extremely dry air mass in recent days featuring abnormally low dew point temperatures of below zero – indicative of very low moisture content in the atmosphere. Strong low pressure will bring this dry stretch to an abrupt end later in the week with significant precipitation from Thursday into Friday. The rain that falls on Thursday and Thursday night in the Mid-Atlantic region can be moderate-to-heavy at times and there is a chance that it changes briefly to snow on Friday as colder air wraps into the system.
