Morning Report

This morning brought a round of snow showers as expected, with temperatures above freezing. This is important as we have another system on the way that may bring more snow with marginal temperatures.

Before we get to that, today we are on the edge of a storm that brought record snow to the Midwest. We will get a push of warmer air and rain this afternoon that may affect travel to end the holiday weekend.

The next event on Tuesday is getting into better focus. The European Model I have highlighted is leading the GFS with the colder solution. This means a track farther south AND the chance for snow to accumulate in parts of Central Maryland and Southern PA. This now has support to include Baltimore City.

Colder air and maybe more snow or a mix is expected to end the work week as well.

Let’s take a look….

The snow that was seen on radar also fell with temperatures above freezing.

Morning Surface Weather

Light snow and flurries in our region ahead of a warm-up. The next wave will be rain this afternoon.

Record Snow has fallen in the Midwest and Great Lakes.

Chicago got 8.4” total. This helped boost their all-time snowfall record for November.

Looking Ahead To Tuesday

These traditional 3 Models still are not in full agreement, but here is what I see:

BEFORE SUNRISE: Start with Snow or Slushy Mix in Central Maryland, including Baltimore.

The European ECMWF Model is farthest south and coldest. This supports more snow and seems to be the way to go.

Surface temperatures shown below are from the National Blend of Models. This is the wild card with what can stick. There will be areas that get snowfall where temperatures are above freezing.

PROBABILITY OF 1” Snow Or More: ECMWF Model Ensemble

• This has INCREASED to nearly 100% for inland suburbs.
• Baltimore is now at 60%.
• I am still cautious that not all that falls may stick.

National Weather Service Forecast

• This now includes 1 inch for Baltimore
• Northwest suburbs in the 1 to 3 inch range

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
