Sunday Afternoon Update
A Severe Thunderstorm Watch has been issued for most of Maryland west of the Chesapeake Bay and South Central Pennsylvania until 7 PM. This was anticipated with the approaching cold front. Multiple rounds of storms are expected, and they will arrive at different times across the region. It is important to note that not all will see the same intensity of storms, but there is potential for high elevated alerts.
In this report is a look at two computer model simulations and the live radar to compare.
Severe Thunderstorm Watch: NOAA
This means there is potential but not a promise. We have the ingredients for storms to form and turn severe. If any cells do reach the criteria, then a Warning will be issued and that storm will be tracked through specific towns and counties.
A storm is considered severe if it has:
- Winds over 58 mph
- Hail over 1 inch in diameter
- Isolated tornadoes or rotation
Any storm (even if not severe) may produce blinding downpours, flash flooding, and dangerous lightning.

I shared this map this morning. It matches the Watch Counties.

I added an extra hour before and after the slider above…
Please consider this product has recently been underplaying rain coverage and about 1 hour slower than verified.
HRRR Model: 2 PM to Midnight
This model keeps some spotty showers or storms around later into the evening for central Maryland, but much less intense for Southern Maryland and Delmarva.
I think a hybrid between this and the other model solution is likely to be what will verify.
