Wednesday morning report

We’re having a very busy weather day as this strong storm develops across our region. It is already raining and will be heavy at times. Winds will shift throughout the day, resulting in dropping temperatures this afternoon and this evening.

The rain will end up as snow for a few hours inland. Temperatures will remain above freezing for many, but a slushy layer is possible this evening. Temperatures continue to fall below freezing in these inland areas (which were blanketed last week) and may become freezing overnight.

I want to do something different this morning. First, the warnings. Then the simulations for radar and winds, followed by snapshots of important time frames.

Weather warnings today

• Dense fog advisory for the Baltimore metropolitan areas
• East Coast Wind Warning: Gusts up to 50 miles per hour
• Winter weather warning for snow levels of 2 to 4 inches in the high mountains

Wind forecast: 7:00 a.m. to 10:00 p.m

Below are key snapshots of the time frame

Radar simulation: 7:00 a.m. to 10:00 p.m

Below are key snapshots of the time frame

Heavy rain will end with snow breaking out inland and snow accumulating in the mountains.

Local morning temperatures

Morning surface weather

The storm is developing and getting stronger. Very fast jet stream level winds, up to 150 miles per hour, will prepare for the event.

Surface warming this morning in the 60s with heavy rain will transition to colder winds this afternoon.

Snow is expected to accumulate in the mountains.

The strong winds are due to the strengthening storm and cold air will move in for a few days.

Snapshot key times

Please note that the NAM 3Km model error often causes precipitation to arrive and depart an hour or two later than indicated. The cold/icy air may arrive an hour or two later than indicated.

The possible domestic icing could become a problem here.

Total Rainfall POTENTIAL

Even if we get 1 to 2 inches of rain, it’s a small dent in the larger drought, which is just over an 8-inch deficit.

REPEATING MY MESSAGE ON THE TOPIC OF LEGEND

I understand that there are some spelling and grammatical errors, as well as occasional other errors. I take responsibility for my mistakes and even the computer errors I may miss. I’ve made a few public statements over the years, but if you’re new here you may have missed it: I have dyslexia and found out about it in my sophomore year at Cornell University. However, that didn’t stop me from getting my degree in meteorology and being the first to receive the AMS CBM in the Baltimore/Washington region.

One of my professors told me that I had made it this far without knowing it and that I shouldn’t let it be a crutch for the future. That was Mark Wysocki, and he was absolutely right! I miss my proofreading mistakes. The automatic spell checker on my computer sometimes misses the mark and makes the problem worse. I can also make mistakes in forecasting. Nobody is perfect at predicting the future. All maps and information are correct. The “wordy” stuff can get sticky.

There was no editor to review my work when writing and have it ready to ship in a newsworthy time frame. Barbara Werner is a member of the web team that helps me maintain this website. She has made it her mission to correct typos when available. That could be AFTER you read this. I accept that and perhaps prove that what you read is really mine… It’s part of my charm. #FITF
