Morning Report

The precipitation began early this morning within reason of the expectation, just a little sooner.  There has been a wide range of slushy snow, sleet, and chilly rain. The complicated part is that this is NOT the same for everyone. Also, there was some evaporative cooling at the start, so a change to snow after it begins, then back to rain gradually.

WINTER WEATHER ADVISORY

This goes through 1 PM.

Reminder the Western parts of Howard and Montgomery Counties in Maryland were added in the expansion.

HOWEVER, the NWS WILL CANCEL Counties as temperatures warm across the region.

SCHOOL DELAYS

The districts that made a call last night were extra cautious AND have parents who complain when last-minute decisions are made. The ‘night before’ calls are for parents to have time to adjust their plans or care for the kids.

Frederick County, MD, CLOSED because they had a 1/2 day scheduled anyway… So the delay was not possible.

HEADLINES

• The intensity and variation of hills and valleys inland also make for a wide variety of places where it may stick and accumulate.
• There has been a lot more SLEET in the northern zones of Maryland.
• In metro areas closer to Baltimore, the roads are still expected to be wet.
• Traveling North into Central Pennsylvania (north of Harrisburg) and the Poconos. This region will have 3 to 6 inches of snow.
• Doppler Radar WINTER INTERPRETATION is NOT PERFECT. So, depending on your source, it may show different results. I’ve seen that in my office this morning.
• Temps will warm and turn this to rain during the morning, which will be heavy at times.
• This will end this afternoon with rain and wet roads.
• Temperatures tonight will drop below freezing, but roads should dry before any icing.
• Friday brings a chance for snow or a mix to the region.

My View North of Baltimore

Temp was 32°F, which dropped from 33°F when the snow began. Some stickage on elevated surfaces.

Doppler Radar AND Observations Snapshot at 6 AM

A lot of the MIXING has been with SLEET. This can still be slippery, where it can lay and stay. Mostly Elevated Surfaces.

UPDATE at 7:15 AM

Morning Surface Weather

This plot of the storm has had trouble identifying the snow, mix, and chilly rain.

Forecast 7 AM to 7 PM: HRRR Model

Noon Set Up

Low Pressure off the coast will bring heavy rain across Southern Maryland and Delmarva.

More cold air will be flowing into the Eastern US.

There will be one impulse on Friday before the next surge that may produce snow or an icy mix.

Friday Morning Surface Weather

This setup does show High Pressure to our North making it cold enough to help hold that cold as Low Pressure organizes to our South.

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
