Saturday December 23

This is a quick update for the purpose of sharing the radar simulation timeline this evening. Moderate rain is moving through as I write this just before 5 PM. Whether you are heading to The Ravens game or a holiday party, I want to help you plan ahead. The rain will be briefly intense and then end,  but the temps will drop.  The next round of rain will arrive Sunday evening that may impact anyone going to church or last minute traveling. We still have a chance for snow to close out this event. Here’s a look below.

This model is not perfect, so compare the 4:55 PM Doppler at the top of this post to the first image here for any adjustment in speed and location.

Mild evening will end chilly as the temps will tank behind the rain. This might have the biggest impact on the Ravens game.



Christmas Eve

Morning Temps will drop close to freezing inland. There could be some icy spots early

Christmas Eve

Rain returns in the evening. There could be some new or sleet mixed well north and west, but the temps should be warm enough for it to melt.


Will It Snow?

This is where I think the computer models are still struggling for our region. I see the decent chance for this to end with flakes for a few hours, especially north and west of Baltimore. Look out the window after midnight and you may see the snow flying by.  Stickage, that might be limited as I see it now. But s coating on the ground in northern, western Maryland and southern Pennsylvania is possible. 



Christmas Morning

The ‘stuff’ from the end of the storm will have moved away by sunrise. The temperatures will be down below freezing west of the Chesapeake Bay. Then we progress to an much colder pattern all week long.

Temperature Outlook

Notice the days that are projected to only reach the 20s

I will have my next update on Sunday morning. This will included the potential for a larger storm next week.
