May 22 2022
This mini heat wave will be ending today. We still have one more hot day that will contain a cold front bringing in late day storms. There is a low chance to turn severe, but enough to mention. What follows will be a much more comfortable week ahead.
First, let’s recap the high temperatures yesterday. Baltimore’s BWI was one of the hottest reporting stations (typical) but just missed the 1934 record by one degree.
That 99ºF reading in Westminster seems to continue to show that instrument needs to be examined for possible recalibration.

Temperatures At 7 AM
Comfortable and not too humid…

RECORD HIGH: 98ºF in 1941
Most of our region is in the Level 1 of 5 – Marginal Risk. That is low, but still a chance that some of the storm cells could turn severe. The Primary threat would be damaging wind gusts over 60 mph.
There is a higher chance across the Poconos into central New York and Northern New England.

The HRRR and NAM show slight variations…
- The HRRR has one line of storms for meter areas, then lingering heavy rain south through midnight.
- The NAM 3 Km has two bands of rain, with the first falling apart near metro areas earlier at 5 PM, then a second broken line later around 10 PM.
One line of storms for metro Baltimore between 7 and 8 PM
This today suggests a storm line passing Baltimore between 7 and 8 PM, then the line regenerates to the south.
Animation: 4 PM to 11 PM
NAM 3 Km
Two separate lines breaking up around metro areas…
5 PM- First line west of the cities, but breaking up…
7 PM- The first line fades as it reaches the Bay, then a second stronger line approaches from the mountains.
10 PM – The cold front still not showing a solid line, with breaks and dry pockets.

Cooler winds from the ocean will keep us in the lower 70s with additional clouds for a few days. Warmer air and more active weather will return by the end of the work week.

*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.
