Monday December 27
We may end up with one of the warmest Decembers on record, but winter is trying to fight its way in. Just cold enough for a mix of slushy snow and sleet this morning, but surface temps are marginal at best.
Below is a round up of temps this morning and through the day, travel issues will be north in Central PA to the Poconos.
Most of the week will be mild with rain showers, starting with the afternoon.
This narrow band of wintry weather is in the process of developing. So the precipitation will be enhancing and it spreads east.
At first, it may show on radar then dry up on the way to the ground… This will actually cool the atmosphere through evaporation and sublimation.
The result, if you begin with rain, it should mix with sleet and snow. But the warm air will win, and turn it back to rain after a couple of hours.
Note: We can expect central Maryland to central PA to begin to see this between 8 AM and 10 AM
7 AM to 7 PM
The HRRR Model shows the anticipated radar. A barrow band of snow and sleet may last 1 to 3 hours.
There will likely be more coverage than shown here. This product has a flaw to under-represent. That is why I include metro Baltimore and more of central Maryland.
Metro areas may begin with rain, then mix with sleet and snow, then back to rain by noon.
Normal Low in Baltimore: 26ºF
Record 5ºF in 1914
Normal High in Baltimore: 43ºF
Record 69ºF 2015
Monday Afternoon to Thursday Afternoon
An active pattern with mild air will keep the risk of rain showers with us most of the week. After a break on. Tuesday, showers return Tuesday night. The bulk of the rain is expected Wednesday night into Thursday morning.
The driest day of the week will be Friday, New Year’s Eve. Rain and chilly temps expected New Year’s Day
