Thursday Late Morning Update
It still feels like summer outside. Many areas began the day in the 60s and 70s, aiming for another push into the 80s. This is well above ‘normal’ but not a record. Also, considering the snow/sleet mix last weekend and Frost Advisory on Monday morning, this big swing is actually pretty common. It does however come with a price. That is a return back to reality with likely storms.
Most of our region is in target for a quick line of thunderstorms this afternoon. There is a small chance that can turn severe, which NOAA has identified with the Severe Storm Outlook. While the higher level is painted over Northeastern Maryland and Eastern PA, there is still a marginal chance for central Maryland to get a storm to turn severe.
A severe storm by definition has one or more of the following:
- Winds over 58 mph
- Hail over 1 inch diameter (size of a quarter)
- Flash Flooding
- Isolated Tornados
Should the threat increase, one of two advisories will be issued:
Watch (Severe T’Storm or Tornado): This means it ‘MIGHT’ happen, but not promised. It’s a better chance and we are paying attention
Warning (Severe T’storm or Tornado): This means it IS HAPPENING NOW and BEING TRACKED. In this case specific counties and towns in the path will be listed.
Any thunderstorm can have:
Dangerous lightning
Timeline slider—> NAM 3 Km
This is guide not a promise.
I would allow a 1 hour buffer, so for example: 4 PM shows storm near Baltimore… Plan for that region any time between 3 PM and 5 PM.

*Disclaimer due to frequent questions:
I am aware there are some spelling and grammar typos. 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 at my second year at Cornell. I didn’t stop me from getting my meteorology degree, and being first to get the AMS CBM in the Baltimore/Washington region.
I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse.
All of the maps and information are accurate. The ‘wordy’ stuff can get sticky.
There is no editor that can check my work when I need it and have it ready to send out in a newsworthy timeline.
I accept this and perhaps proves what you read is really from me…
It’s part of my charm.
