January 13 Mild Ahead Of Arctic Front That Will Bring Rain To Snow Later Wednesday
Tuesday January 13
We are once again back to mild afternoons with sunshine, but that is about to change. The next cold front will usher in a series of arctic air masses, returning us to the cold winter we experienced at the beginning.
With the cold front on Wednesday, rain will change to a brief period of snow overnight. The snow may last for an hour or two in most areas. This may drop a coating of snow or more, then end before sunrise on Thursday.
A little more snow may fall north of Baltimore and also on Delmarva. But the sun and wind on Thursday will dismiss that quickly.

Morning Surface Weather
For Baltimore and the Mid-Atlantic: Mild conditions continue today as we sit on the warm side of the front. Enjoy it while it lasts — big changes are coming!
- Snow/Rain Mix: A low-pressure system over the Upper Midwest is producing a snow and rain mix from Minnesota through Wisconsin and Michigan.
- Arctic Air On The Way: The main story — a surge of arctic air is diving south from Canada. This cold air will arrive Wednesday night into Thursday, dropping temperatures significantly.

Rain to snow for an hour or two. This may drop a coating of snow with closer to 1 inch near and north of the PA line.

A brief period of snow on Delmarva may also drop a coating of snow.

This is the most I see possible and will be ending before sunrise on Thursday.

Storm Forecast Thursday to Saturday
As the cold air crosses the Eastern US, the snow will be prevalent across the Great Lakes. After the Wednesday night front, all I see are snow showers or flurries at times, but no major events on the horizon.

Jet Stream: Thursday Snapshot
This new push of arctic air will work all the way into the Deep South and Gulf Coast. We all transition to the colder air on Thursday.

Jet Stream Forecast Jan 15 to Next Tue Jan 20
Reinforcing cold air over the next week, and it is likely more will follow.
While we may see some snow showers or flurries, I do not see any storms at this time.

The second push of arctic air may be colder for our region.

RESTATING MY MESSAGE ABOUT DYSLEXIA
I am aware there are some spelling and grammar typos and occasional other glitches. I take responsibility for my mistakes and even the computer glitches I may miss. I have made a few public statements over the years, but if you are new here, you may have missed it: I have dyslexia and found out during my second year at Cornell University. It didn’t stop me from getting my meteorology degree and being the first to get the AMS CBM in the Baltimore/Washington region. One of my professors told me that I had made it that far without knowing and to not let it be a crutch going forward. That was Mark Wysocki, and he was absolutely correct! I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. I can also make mistakes in forecasting. No one is perfect at predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky. There has been no editor who can check my work while writing and to have it ready to send out in a newsworthy timeline. Barbara Werner is a member of the web team that helps me maintain this site. She has taken it upon herself to edit typos when she is available. That could be AFTER you read this. I accept this and perhaps proves what you read is really from me… It’s part of my charm. #FITF
