A powerful low pressure system will form in the central Plains on Friday and take a northeastward track towards the western Great Lakes region. There will be strong support in the upper-atmosphere for this system and a second strong upper-level low will slide eastward across the southern states on Saturday morning and then turn northeast to the Tennessee Valley. This southern system will combine with multiple jet streaks to help destabilize the atmosphere from late Friday night through Saturday evening. As a result, showers and thunderstorms are likely here from late Friday night into Saturday night and some of the thunderstorms can reach severe levels with damaging wind gusts and strong tornadoes on the table.

An ocean flow of air will continue to keep it on the cool side around here and there will be plenty of low clouds around limiting any potential heating during the day. There is a total lunar eclipse later tonight, but these same low clouds can have a negative impact on overall viewing conditions. If it is indeed visible, the “totality” phase of the lunar eclipse will last for about an hour from around 2:30-3:30 AM.
Temperatures will climb a bit on Friday with the possible return of some sunshine, and then they’ll surge this weekend to very mild levels on both Saturday and Sunday. The weekend will become quite wet, however, with the chance of showers later Saturday and Saturday night and then occasional rainfall on Sunday. The rain on Sunday can become heavy at times as a strong cold front slides eastward towards the coast and there can be a strong thunderstorm included as well. It turns cooler on Monday in the Mid-Atlantic region following the passage of the cold frontal system, but the cool down will be brief and we’ll get very mild again by the middle of next week.

The winter of 1992-1993 was not bad at all in the Mid-Atlantic region in terms of cold and snow, but one storm at the end of the season will put that particular winter in the history books forever. One of the most intense storms ever observed in the eastern US took place from March 12-14, 1993 and it will be forever known as the “Storm of the Century”. This intense storm generated tremendous snowfall totals from Alabama through Maine, high winds all along the east coast, extreme coastal flooding along the Florida west coast and incredibly low barometric pressures across the Southeast and Mid-Atlantic regions. The aftermath of the “Storm of the Century” was unseasonably cold and broke records in many spots for the middle of March. To this day, the storm also known as the “Superstorm of 1993” ranks among the deadliest and most costly weather events in US history.

The passage of a “back door” cold front will bring cooler conditions to the region for both today and tomorrow as low-level winds have shifted from a southwesterly direction to north-northeast. (I refer to this kind of cold front as a “back door” since it “sneaks in” from our northeast instead of the more conventional approach of a cold front from our west). Temperatures will begin to rebound on Friday and it’ll be quite mild this weekend. The weekend becomes quite wet, however, with occasional rainfall likely from later Saturday through Sunday. Some of the rain can be heavy at times later this weekend and a strong thunderstorm is possible. It turns cooler on Monday following the passage of a more conventional “west-to-east-moving” cold frontal system.

It remains quite mild for another couple of days with temperatures climbing to well up in the 60’s on each of the next two afternoons. It turns much cooler on Friday following the passage of a cold front and there can be rain and/or snow showers and strong winds to close out the week.

The combination of an intense upper-level low, powerful jet streaks at multiple levels of the atmosphere, strong southerly low-level flow of warm, moist air, and a deepening surface low pressure system will likely lead to a severe weather outbreak from later Friday into Friday night. Indeed, this threat of severe weather may continue right through the upcoming weekend as it shifts slowly to the east reaching the Atlantic seaboard by the latter part of the weekend. The deepening surface low pressure system may reach central pressures not often seen in this part of the nation which will result in a very strong pressure gradient potentially leading to widespread damaging winds. In addition, this unfolding atmospheric setup can lead to some strong tornado activity from later Friday into Saturday across portions of the central and eastern US.

Today will be a nice day throughout the Mid-Atlantic region with plenty of sunshine and afternoon high temperatures well above normal for this time of year. A “back door” cold front will bring cooler air back to the region for tomorrow as low-level winds switch to a north-northeast direction. (I refer to this kind of cold front as a “back door” since it “sneaks in” from our northeast instead of the more conventional approach from the west). Temperatures will surge to milder levels at the end of the week and it’ll stay quite mild through the upcoming weekend. The weekend becomes wet, however, with showers possible from late Saturday through the day on Sunday and some of that rain can be heavy at times.
