After several days of mild weather in the Middle Atlantic region, a piece of the infamous Polar Vortex will move into the northeastern states during the next week. Although not as cold as the previous visits of the vortex, our temperatures will tumble this week and drop 10 to 15 degrees below seasonal averages. For example, daytime highs in late February should be in the mid to upper 40s, but highs later this week will only reach the mid 30s on average. Overnight lows may drop into the teens and lower 20s. Another shot of cold air may move into the region later in the weekend. Even though we are not expecting any record-breaking cold this week, we will feel its presence. The daytime sun is bright, but there will be a biting wind and sub-freezing temperatures for much of Wednesday, Thursday, and Friday in Maryland, Delaware, and Virginia.

Over the past week various weather forecast computer models have indicated the potential for snowy weather around February 26 and again around March 1. At times these models have shown a moderate snow event around the 26th and the potential for a more significant coastal storm around March 1. However, these models have progressively weakened both systems. On Wednesday the 26th, a weak area of low pressure may brush southeastern Virginia and coastal Maryland and Delaware with some light snow; however, areas to the west across Baltimore, Washington, and Richmond can expect snow showers or very light snow by Wednesday morning with little or no accumulation. The system around March 1st that computer models had aggressively developed now appears to be weakened and suppressed by the surge of cold air that will overspread the Middle Atlantic and New England states later this week. There is still time for this particular system to develop into something more significant, but right now it does not appear to be a threat for winter weather.
