Heavy rain then light snow for Christmas Eve

Good Saturday and welcome to Christmas weekend. We have a ton of rain falling on the region today, and this is bringing the potential for local high water issues. Once this goes through, temps crash with the increasing threat for light snow on Christmas Eve.

Today’s rainfall will be heaviest through the early part of the afternoon. All tolled, most areas will have picked up 1″-3″ of rain before this ends. We will need to watch the creeks and streams, and poor drainage areas for high water issues:

Temps crash from northwest to southeast today, leading to the potential for some light snow to mix with the rain in the north by late this afternoon.

As temps go below freezing tonight, watch for a few slick spots to develop.

This brings us to our Christmas Eve system and the increasing threat for a light snowfall. The models continue to trend a little stronger with this system from late Sunday into Christmas Eve.

This action may begin as a mix before quickly going over to light snow:

The GFS continues to increase the light snow numbers, and now has several areas hitting 1″ or a little better:

The NAM also increases the swath of snow on each run. Here’s the future radar and Satellite:

Given the very wet ground,  we will likely see melting taking place Sunday afternoon, before getting in on sticking snow after sundown. Much of our region is likely to get in on a coating to 1″ of snow:

Some areas may do a little better than 1″, but I’m not ready to bite on that just yet.

Roads are likely to be wet through the daylight on Sunday, then may ice over after the sun goes down. Road crews won’t be able to pretreat because of all the rain falling today, so we will need to be on guard for slick travel developing Christmas Eve into Christmas morning.

Winds are very gusty during this time, with single digit wind chills showing up as Santa arrives:

Christmas morning flurries will then give way to a partly cloudy sky with a cold wind continuing to blow.

That wind may blow a batch of light snow and flurries back into the region Christmas night and Tuesday.

We continue to see the models showing a winter storm impacting our region and the eastern half of the country from Wednesday through Friday:

Make it a great Saturday and take care.
