Discussion
The core of the coldest air associated with the current Arctic outbreak moves into the Mid-Atlantic region today and temperatures here will struggle reach the upper 20’s (normal high is 44 degrees at DCA). In addition, winds will be quite stiff from a northwesterly direction bringing wind chill values to below-zero from time-to-time. Temperatures later tonight could plunge to the middle teens and then they’ll likely reach the upper 30’s by tomorrow afternoon. There will be a temporary modification in temperatures on Thursday and then another Arctic air mass will push in for the upcoming weekend.
By Friday night and Saturday, moisture will start gathering across the south-central states. As this moisture shield then heads to the north and east, it will encounter a very cold air mass having its origins in the Arctic region. As such, frozen precipitation will break out with significant - and potentially crippling - icing possible this weekend across many southern states. As the moisture field pushes farther to the north and east, snow will break out, and significant accumulations are on the table in the region from the Middle Mississippi Valley to the Tennessee Valley to the Mid-Atlantic region...buckle up, the next couple of weeks will feature the worst that winter has to offer.
