Discussion

After a quiet start to the week, our recent active weather pattern will return with a significant storm system to deal with on Wednesday and Thursday and then yet another low pressure area this weekend. High pressure will be in control today and temperatures will climb way up to near 60 degrees. In fact, today will likely turn out to be the warmest day of the week. Weak low pressure located over the Great Lakes this morning will swing a cold front through the region in the overnight hours paving the way for a chillier day on Tuesday. Canadian high pressure will then build into the region by Tuesday night and it will set up anchor in southeastern Canada by the middle of the week. This cold high pressure system will play a key role in the mid-week time frame as a cold air damming situation will develop sending cold, low-level air down the I-95 corridor. At the same time this high sets up shop in southeastern Canada, a moisture-rich storm will pull out of the Rockies and head towards the Great Lakes. This storm will then grind to a halt and gradually weaken as a secondary system tries to develop along the Mid-Atlantic coastal region by Thursday. This complex combination of the cold, strong high pressure system to the north and the double-barrel low pressure system will set the stage for a long-duration event from Wednesday into Thursday with significant snow and/or ice likely across northeastern PA, NW NJ, Lower Hudson Valley, NY and southern New England. While odds favor rain around here in the DC metro region during this mid-week event, some ice cannot be ruled out in the far northern and western suburbs. Stay tuned.
