It remains windy and chilly today in the wake of a secondary cold frontal passage on Thursday afternoon with gusts of 40+ mph on the table. A weak system will pass by tonight and it can produce a few rain and/or snow showers, but nothing too significant. Widespread warming across the middle of the nation will spread east next week and it’ll produce “spring-fever alert” type weather here next Tuesday, Wednesday, and Thursday with high temperatures in the 60’s. One final note, it is time this weekend to turn the clocks ahead an hour to switch back to Daylight Savings Time.

A strong cold front passed through the region last night and it has ushered in a noticeably cooler air mass to the Mid-Atlantic region. Winds will become very strong later today from a west-to-northwest direction as a secondary cold front crosses the region….gusts to 50 mph are possible by day’s end. A weak system will push into the area on Friday night with a few rain and/or snow showers possible and the weekend looks to be on the chilly side for early March.
Looking ahead, a big-time warmup is on the way for next week which can feature high temperatures near 70 degrees by Wednesday (not quite done with the cold shots though). One final note, this weekend is that time once again to push clocks forward an hour as we flip back to Daylight Savings Time.

Ingredients are in place for strong-to-severe thunderstorm activity later today into early tonight along the DC-to-Philly-to-NYC corridor which will include downpours and the possibility of damaging wind gusts. In addition, a few isolated tornadoes are on the table later today in the Mid-Atlantic region and an enhanced risk of tornadoes will take place farther to the south from southeastern Virginia into the Carolinas. Meanwhile, in the storm’s cold sector, there are blizzard conditions today across portions of Iowa, Minnesota and Wisconsin where 60+ mph winds can cause considerable blowing and drifting of snow.

Strong thunderstorms are possible later today into early tonight as a strong low pressure system heads to the Great Lakes. There will be occasional showers here today and afternoon/evening thunderstorms and some of the rain will be heavy at times. Any thunderstorm that forms from mid-day on through the evening hours can result in damaging wind gusts and hail. In addition, isolated tornadoes cannot be ruled out in the Mid-Atlantic; primarily, in areas to the south of the PA/MD border. It turns colder and remains windy on Thursday following the late night passage of a strong cold front and gusts can surpass 45 mph or so. Looking ahead, the weekend will be chilly, but a big warmup next week could bring temperatures to the 70 degree mark in the DC-to-Philly-to-NYC corridor.

Ingredients are in place for a severe weather outbreak today and tonight with its focus on the Lower Mississippi Valley and central Gulf coast. There is a high risk of damaging wind gusts in this scenario and tornadoes are certainly on the table with the possibility of a few strong ones. This threat shifts to the east coast on Wednesday where damaging wind gusts, heavy downpours, and even isolated tornadoes will be a possibility from the Mid-Atlantic to the Southeast US.

A spring-like storm is on the way for the Mid-Atlantic region with windy and warmer conditions on Wednesday, a soaking rainfall, and a possible strong thunderstorm. This same storm system will result in an enhanced risk of severe weather later today and tonight across the Lower and Middle Mississippi Valley regions. The main risk both today in the Mississippi Valley and tomorrow in the Mid-Atlantic will be for damaging wind gusts; however, isolated tornadoes are certainly on the table as well. It’ll turn cooler on Thursday and Friday behind the passage of a strong cold front and high pressure will build back into to the area.

The month of March is now underway and it certainly can feature multiple severe weather outbreaks as the air becomes increasingly warm and humid across the southern states at the same time colder-than-normal air masses continue to push south and east from Canada into the US. The ingredients are falling into place for severe weather during each of the next three days as indeed colder-than-normal air from the western states will push eastward into a warmer-than-normal air mass that today will be centered over the central states. The main threat zone for severe weather today is likely to extend from Texas-to-Oklahoma-to-Kansas and then an enhanced risk is likely on Tuesday centered over the Lower and Middle Mississippi Valley region. Spring-like storm conditions will reach the eastern states on Wednesday with windy, warmer weather, soaking rainfall, and the potential of strong-to-severe thunderstorm activity.

A spring-like storm is on the way for the middle of the week with soaking rainfall, windy and warmer conditions, and a possible strong thunderstorm as well. After a cold Monday and a milder Tuesday, temperatures will soar on Wednesday ahead of a strong cold front possibly reaching the mid-to-upper 50’s. It’ll turn windy and cooler behind the front on Thursday and Friday as high pressure returns to the region.

A cold front closes in on the area later today and it will produce some shower activity and perhaps even an isolated thunderstorm or two. Moderately chilly air will follow into the Mid-Atlantic region on Friday, but it then turns windy and milder on Saturday as a “clipper” system passes by well to the north of here. That system will drag a cold front through the region and it’ll turn quite cold once again for the early part of next week.

Today’s weather features above-normal temperatures across much of the nation and the next couple of days will remain on the mild side in the Mid-Atlantic region with high temperatures approaching 60 degrees in some areas. We are about to flip the calendar from February to March and it appears quite likely that there will be occasional cold air intrusions from Canada into the US during the next few weeks. Supporting evidence for additional cold air outbreaks during the month of March include the strong likelihood of a “disrupted” stratospheric polar vortex with significant warming near the North Pole by the middle of March and the movement of a tropical disturbance known as the Madden-Julian Oscillation (MJO). These occasional cold air outbreaks will contribute to an overall active weather pattern in the month of March and likely set the stage multiple severe weather outbreaks. In addition, the continuing cold air intrusions will certainly keep hope alive for snow lovers with multiple upcoming chances; especially, across interior higher elevation locations of the northern Mid-Atlantic and Northeast US.
