Friday Afternoon, February 16

The expectation for colder temperatures to maximize snow accumulation is now being validated by The National Weather Service. The Winter Storm Warning now includes all of Central Maryland, including Baltimore. This is for the expectation of 4 to 6 inches of snowfall overnight.

Snowfall rates will be 1 to 2 inches per hour overnight as temperatures drop below freezing.

A Winter Storm Warning remains in place for Frederick County, Maryland, and westward for the highest totals to likely exceed 6 inches.

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 up the totals higher.

Snow will exit the coast, but the upper-level energy may keep snow showers and flurries inland for a few extra hours.

11 AM

Snow should be coming to an end.

Afternoon Temperatures

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
