June 26, 2023
Monday Morning Update
The weather set up today supports an eruption of severe storms. With the humidity in place, higher temperatures, wind direction, wind shear, and colder air aloft all combine into what may be a widespread outbreak of extreme weather.
NOAA has expanded the Enhanced Risk for severe storms. That is level 3 out of 5 and I have more details and a potential timeline below. We can compare the forecast radar simulation to the live radar. While there could be a morning shower, the main activity will build after 2 PM.
Alerts Expected Today
Watch: This will be issued for a larger time window when there is POTENTIAL NOT A PROMISE for storm conditions to develop.
Warning: This is issued when storm conditions are OCCURRING NOW! This may be for flash flooding, damaging wind, large hail, or tornadoes.
Any storm can produce dangerous lightning.
The good news is that while we have storms through tomorrow, we may get the quiet weather to return on Wednesday and Thursday.
Sunday Storm Reports
Looking back at yesterday, the Storm Prediction Center accounted for
- 4 Tornado Reports
- 376 Wind Damage Reports
- 187 Hail Damage Reports
NOAA Severe Storm Risk Today
The Enhanced Risk bullseye includes most of eastern Virginia, Maryland, all of Delaware, into Southern New Jersey. The Slight Risk does reach up I-95 to metro New York.
The risk includes:
- Flash Flooding
- Dangerous Lightning
- Wind Gusts over 60 mph
- Large Hail 1 to 2+ inches in diameter
- A few tornadoes. This may include energy to build over EF-2
Morning Surface Weather
A Warm and Humid air mass is in place and the heat will crank up today through tomorrow.
A large cold core Low located over Minnesota is the reason for very active storms along that boundary. While a few pop-up showers will develop this afternoon. The severe storm risk will reach us today. This is a slow moving pattern, so it may stay with us for a few days.
Live Radar
This will get more active after Noon
Severe Storm Risk: Closer View
Where this line is located is based on the timing of the storm line forming. It is negotiable and not important if you are close to the edge. Just consider the risk for a busy afternoon.
- The Slight Risk (yellow) is farther west and lower due to the timing of the formation of the storm line.
- The Enhanced Risk (orange) includes Washington, Annapolis, Baltimore, to Philadelphia, Southern Maryland and Delmarva.
Note: As I wrote in last night’s report: The conditions are favorable for widespread severe storms.
- Winds FROM the Southeast are most favorable for metro Baltimore
- Surface CAPE= Over 2,200 J/Kg supports a volatile environment for severe storms and supercells.
- Temperatures will approach the lower 90s with a higher heat index!
Afternoon Temperatures
These are the expected peak temps before the storms roll in. Notice the drop into the 70s and 60s where the storms have passed.
Radar Simulation
NAM 3Km Noon to Midnight
I need to emphasize that this product is a good guide, but has limitations. It often is slower and less active than we end up seeing.
Timeline Suggestion From The National Weather Service
Compare to timeline slider below
Timeline Slider —> 3 PM to 10 PM
Reminder: We may verify storms up to 1 hour earlier and they could be more active than shown here.

It will be muggy, and there may be some thick fog to start the day.
Afternoon
Not as warm, but still unstable. More showers and storms will help to keep temps in check.
Rain Forecast Tuesday Morning To Thursday Afternoon
The continue ‘pulsing’ of storms each afternoon and evening will persist Tuesday and Wednesday. This is expected to settle back to scattered showers and more dry days towards the end of the week.
Tuesday: Widespread showers and thunderstorms again with potential for severe conditions. This can include flash flooding, damaging winds, large hail, and isolated tornados.
Wednesday and Thursday: We may turn quiet earlier than expected…
7 Day Forecast
The latest suggestion is for the worst storms today, however tomorrow may be quite busy as well. Then we lower the storm chance on Wednesday, with Thursday and Friday turning quiet.
This holiday weekend will bring back more summer storms.

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 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 predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky. There has been no editor that can check my work when I needed it and 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 able. 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.
