Brian's exclusive forecast for Baltimore, Annapolis, and northern Delmarva:
Today: Clouds and sun, breezy and chilly, few snow flurries or rain drops. High 43.
Tonight: Becoming mostly clear with a low in the upper 20s.
Wednesday: Mostly sunny and cold with a high around 35.
Wednesday Night: Mostly clear with a low in the mid 20s.
Thursday: Mostly sunny with a high around 40.
The extended outlook calls for mostly sunny conditions on Friday and Saturday with lows around 30 and highs around 45. Mostly cloudy on Sunday with a low around 35 and a high around 50.
Temperatures this morning only feel cold because of the 70 and 80-degree readings from just two days ago. Current temperatures are in the mid to upper 30s around the region, but the mercury will not be rising all that much today with highs only expected to reach the lower 40s. The wind will be gusty at times from the northwest, making it feel even colder. An upper-air disturbance moving through the northeast today may produce a few renegade snow flurries or rain drops, but otherwise clouds and sun will be the main weather feature. The weather this week, despite the downturn in the thermometer, will be rather pleasant and tranquil for late December as high pressure builds overhead. From Christmas Day through the end of the week, temperatures will moderate from the 30s into the 40s and then near 50 by Sunday. Meanwhile, a pattern shift in the atmosphere is setting the stage for significantly colder air to overspread the northeast states during the first two weeks of January. Two factors include the shifting of the Polar Vortex to the south and stratospheric warming. The result will place the Middle Atlantic and New England states in a deep freeze for a period as we enter the new year. At the same time, the storm track will become more favorable for snow and ice. More information on this pattern shift will be posted as new information becomes available. Until then, we can enjoy a nice week of weather with plenty of sunshine and seasonable temperatures.
