Winter Storm Warning And Advisories Expanded Through Maryland

Friday Late Morning Update February 16

Now as we get closer to the event, some of the ‘watch’ areas have been updated based on the snowfall expectations. Not all are in the same category.

A Winter Storm Warning has been issued for Frederick County, Maryland, and westward for the highest totals to likely exceed 6 inches. 

A Winter Weather Advisory has been expanded to cover the rest of the north-central Maryland counties. The inland suburbs west and north of Baltimore will still see a moderate snowfall and have the potential for bursts to exceed 6 inches. But many areas may remain just under that threshold. 

Here is the summary, then, compare My Call For Snowfall to the NWS Maps. Below are the model maps as well.

Note: Snow may fall at the rate of 1 to 2 inches per hour. Colder temperatures in the higher elevations will allow for a ‘dry flake’ and fluff of the totals higher.

The daylight will help with melting on the roads.. but as it stays near freezing inland, expect icy spots in the shade and a quick refreeze in the evening.

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 also can 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 when I need it and 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
