May 3 Warm and Humid With Severe Storm Risk Later And More Rain To Follow
Saturday, May 3, 2025
This first weekend of May will start off warm and a tad more humid. The anticipation of rain is now mixed with the risk for severe storms, and the timing is still uncertain.
I can see the potential for storms to turn severe in this pattern, but I have doubts with the high-resolution models… I still show them here in my report, but with the reminder that they are a SUGGESTION.
What will see is a line of strong thunderstorms develop in the mountains this afternoon and spread east across Central Maryland and Southern Pennsylvania this evening and tonight.
Our afternoon may end up drier, but pop-up showers are possible ahead of the main event.
NOAA Severe Thunderstorms Risk
This ‘Slight Risk’ means that any thunderstorm may grow but is not promised to produce damaging winds, large hail, and an isolated tornado.
This zone includes much of Central Maryland and Southern Pennsylvania.
Alert Reminder:
Watch: Are issued for POTENTIAL, NOT a Promise. This will cover a large area for up to 6 hours.
Warning: Gets issued when a storm has formed and is being tracked. This will usually last 45 minutes and include towns in the path.
Drought Reminder
Rainfall Deficit at BWI

Tracking the build-up of strong to severe thunderstorms along with a band of heavy rain….
This will push eastward, and the “suggestion” is just that: A SUGGESTION…
Storms in the mountains form during the afternoon, then move east into Central Maryland this evening and tonight.

SUNDAY
This will be a cooler day with more rain in the morning.
Morning Low Temps
Radar Simulation: 6 AM to 8 PM
Morning rain followed by a break with scattered showers and a few thunderstorms. Again, I do not trust the specifics here, so consider a shower or thunderstorm for your plans.
Afternoon High Temperatures
LOOKING AHEAD
The pattern will be wet for four days, but not a steady rain for the entire time. Monday will be more unsettled, and then the pattern will keep us with off-and-on showers that may build more activity each afternoon with the heat of the day.
Surface Weather: Sunday to Wednesday
Snapshots:
Monday Afternoon
Rain is more likely.
Tuesday Afternoon
Mostly Cloudy with showers on and off… more in the afternoon.
Wednesday Afternoon
Partly to mostly sunny with scattered showers… again more building in the afternoon.
Jet Stream: Monday to Friday
The large upper-level Low in the Midwest will spin itself out…. This is what will be responsible for our unsettled pattern. Then, by Friday, a new impulse of cooler air will drop south from New England.
7 Day Forecast
It looks wet almost every day. This weekend may turn soggy Saturday afternoon into Sunday…
Next week will keep the showers around, with afternoon thunderstorms building in the heat of the day and settling at night.

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 also can 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
