One more day of spring-like temperatures here at mid-week in the Mid-Atlantic region and some record highs may be set in spots as clouds increase ahead of a strong cold front. That strong cold front and a pre-frontal trough can produce showers for the mid-day and early afternoon and then strong-to-severe thunderstorms will be possible later today and early tonight. Much colder air will arrive on Thursday leading to quite a dramatic drop off in temperatures as compared with today’s potential record-breaking warmth. The chilly air will stick around on Friday and the weekend will start off on the cool side with dry conditions likely on both Friday and Saturday. Another strong cold front heads our way for the late Sunday night/Monday time frame with additional showers and thunderstorms possible. A widespread colder-than-normal air mass will then spread into the eastern states by Tuesday of next week on the heels of that next strong cold frontal system.
One final note, it looks like record high temperatures were set yesterday in D.C., Philly and New York City with DCA at 84 degrees, IAD at 85 degrees, BWI at 85 degrees, PHL at 83 degrees, and in Central Park (NYC), it was a record-breaker at 80 degrees and the earliest 80-degrees ever recorded.

A significant severe weather threat exists for later today and tonight in the region from the southern Plains to the Upper Midwest and this risk which includes possible tornadoes will shift east later tomorrow to an area that extends from the Lower Mississippi Valley to the Mid-Atlantic region. Numerous ingredients are coming together for this severe weather threat including a powerful surface cold front, warm and humid air in place, waves of energy aloft in both the northern and southern jet streams, and an incoming colder-than-normal air mass. After possible record-breaking warmth during the next two days in the Mid-Atlantic region, it’ll turn much cooler for Thursday and Friday following the passage of the strong cold front, and a widespread colder-than-normal air mass will push into the eastern states early next week.

Spring-like warmth will continue in the Mid-Atlantic region during the next couple of days and there can be record-breaking high temperatures in some spots. A strong cold front will pass through the region from later tomorrow night into Thursday, and it’ll likely be accompanied by occasional rain and a strong thunderstorm is possible as well. Much cooler air pushes in for Thursday and Friday on the heels of the cold frontal passage and it stays on the cool side to begin the weekend. Another strong cold front heads this way for the Sunday night time frame likely with additional showers and possible thunderstorms.

It took awhile, but the chilly, ocean air that infiltrated our area last week finally retreated this weekend and the next few days will feature much warmer-than-normal weather. The 60’s will be commonplace today for afternoon highs and then the 70’s are likely on Tuesday and Wednesday with a few records possible. The chance of showers and thunderstorms will increase from late Wednesday into Thursday as a strong cold frontal system crosses the region and it turns much cooler for Thursday and Friday.

An east-to-northeast flow of chilly ocean air will persist into tomorrow keeping a lid on temperatures and resulting in some patchy fog around the area and occasional rain or drizzle. The ocean flow should weaken by later tomorrow and this should allow temperatures to climb to the 50’s on Saturday afternoon and into the 60’s on Sunday…very mild weather early next week.

The overall weather pattern remains quite active across the continental US, and it is the time of year for thunderstorm activity to become more prevalent compared to recent weeks. In fact, there can be some thunderstorm activity in the Mid-Atlantic region later tonight as a strong upper-level disturbance passes through the area and heavy downpours are on the table. On Friday, there is an enhanced risk of severe weather across the nation’s mid-section including the threat of tornadoes as a strong upper-level trough ejects northeastward from the southwestern states along with its associated powerful jet streak.

An easterly flow of air has developed around here following the passage of a backdoor cold front which will push off any big-time warmup until this weekend or the early part of next week. Temperatures should hold at normal to slightly below-normal levels during the next couple of days with the development of an oceanic flow of air from the still-chilly waters of the western Atlantic. It remains quite damp as well during the next 48 hours with occasional rain and patchy fog around. On Saturday, the oceanic air mass should retreat to the north and - if this indeed takes place - then temperatures could climb to 60 degrees. It should then be very mild during the early part of next week and a strong front can bring a soaking rainfall to the Mid-Atlantic region during the latter part of next week.

The cold air mass that pushed into the northeastern states earlier this week will retreat to the north today and it turns somewhat milder, but it’ll be damp as well with occasional rain and some patchy fog around. It stays unsettled tonight and tomorrow with additional rain likely and the patchy fog will stick around in some areas. A backdoor cold front pushes through the region by tomorrow night and the end of the week will turn out to be quite chilly with a low-level ocean flow of air. A big-time warmup is then likely to take place here this weekend into early next week and temperatures could soar through the 60’s. There will continue to be a threat of showers from time-to-time this weekend and perhaps a thunderstorm or two mixed into the picture.

Moisture pushes northward this morning into the area and it’ll be cold enough for freezing rain during the morning hours possibly mixed with sleet and/or snow at times…small accumulations of ice and/or snow are possible…watch out for AM slick spots. Temperatures should climb safely above the freezing mark this afternoon resulting in plain rain...afternoon highs likely near the 40-degree mark. It turns much milder for the second half of the week and the upcoming weekend, but the warmup will be plagued by multiple rounds of showers. There is the chance that the warmup gets interrupted on Friday if a backdoor cold front drops through the area from northeast-to-southwest. If indeed this cool down takes place and a low-level ocean flow develops, it would be just a temporary setback to the warmup, and temperatures should soar again this weekend and during the early part of next week.

After a very mild day on Saturday, a strong cold front passed through the Mid-Atlantic region on Sunday and ushered in a much colder-than-normal air mass for the early part of the new work week. The cold front has dropped just to the south of the area and low pressure will ride along the boundary zone today and snow is likely in the DC metro region this afternoon with some accumulations. By tonight, the dominant precipitation type in the DC metro region will be freezing rain and this could last into the early morning hours on Tuesday. Farther north, precipitation is likely to hold off in the Philly metro region until around daybreak on Tuesday and freezing rain will likely be the dominate precipitation through the morning hours. Watch for slick spots in both metro regions before a changeover to plain rain and above-freezing temperatures.
