One of the more frigid March mornings in the history of weather records occurred this morning in the Middle Atlantic states. With a clear sky, fresh snow cover, and near calm winds, the mercury dipped into the single digits in Philadelphia, Baltimore, and Washington. Baltimore set an all-time record low for the month of March with 4 degrees (the previous record was 5 degrees set 141 years ago.) Despite bright late-winter sunshine, readings this afternoon will struggle to reach the mid and upper 20s, which is nearly 25 degrees below average for this time of year. During the overnight hours we can expect temperatures to tumble back down through the 20s and into the 10s by Wednesday morning, with a few isolated spots in the single digits (mainly to the north and west of the cities.) Suffice to say, this morning will be the coldest morning until next winter.
As we look ahead to the rest of the week, the question is whether a moderation in temperatures can be expected. The answer is a resounding "yes". However, two more chilly days can be expected with highs in the 30s on Wednesday and Thursday before eclipsing the 40-degree mark on Friday and Saturday. In fact, as we move into later this weekend and early next week, the temperature is expected to climb into the low mid 50s at some locations. Now, there is a risk of some light snow or snow showers on Thursday night and Friday, but at the moment this area of low pressure should remain far enough out to sea to prevent another accumulating snow.
The long-range outlook indicates that after the warm-up this weekend, which will only take temperatures to more seasonal levels, another shot of cold air may impact the Middle Atlantic region later next week. I'll post more information in the coming days on this potential for another wave of cold. In the meantime, here are some links with more specific forecasts for your location:
