A Soaking Rain on the Way...Then a Pattern Change...

A broad southerly flow has boosted temperatures into the 60s over the area today. We've got another very mild day tomorrow, with afternoon highs closing in on 70. However, it won't last all that long, as a cold front will slide into the area by Thursday morning. Temperatures will be lowering through the 40s on Thursday, as a developing area of low pressure across the Gulf Coast states heads northeast. That will bring us periods of rain, which could be heavy at times. Model guidance is showing the potential for a couple of inches of rain on through Thursday night. As the storm departs early Friday morning, it's even possible a few places could end as a brief period of wet snow if the moisture lingers long enough.

A pattern change on the way...

The pattern we've been in for several weeks now that has produced below "normal" temperatures on average is probably about to come to an end. Our longer range guidance shows a broad, rather flat ridge building over the Southeast next week. That will mean milder days for us. Beyond that, the ridge may strengthen Christmas week, leading to temperatures well above average for the Southeast and Mid-Atlantic, meaning a warm Christmas could be ours this year.
