Update Mon 03/20 @ 9:42 AM — Spring begins at 5:24 EDT today and we’ll be seeing milder temperatures (actually, much milder temperatures) beginning Tuesday.

With all the talk on the radio about how warm it will be later this week, there’s not as much being said about the expected significant increase in clouds and likelihood of rain, perhaps as early as Thursday.

Currently, most models are showing rain moving in during the day Thursday with possible periods of moderate rain Friday and especially Saturday.

Today’s 06z NAEFS – There’s been good run to run consistency with this ensemble forecast for Friday and Saturday. The ECMWF and GFS operational models also show this multi-centered series of low pressure systems moving into our area. (Click on image for a larger view.)
