Wednesday June 10 2020
The local focus on storms may be two-fold: One round this evening, then another close to sunrise on Thursday. Then we will watch that front cross the Bay and impact Delmarva to the beaches during the day tomorrow.
High heat and humidity this afternoon and brought more awareness to the potential strong or severe storms that may form. At 4 PM the line of storms was well developed in western mountains, more so than the short range models have suggested. With temperatures reaching the 90s and heat index values within a few degrees of 100ºF, we must consider this to feed into storms that may be stronger and more widespread.
For a Storm to Severe is must have: Winds over 58 mph, hail over 1″ diameter, flash flooding, and possibly isolated tornadoes.
A Watch means it might happen. A Warning means it is happening now!

Conditions at 4 PM
I think the Westminster 97ºF is a flash reading. That station was own for maintenance, and may need more work.
Doppler Radar snapshot at 4:15 PM
The real view this afternoon is more active than the most aggressive short range model (NAM 3 Km shown below). This is the suggest that we may expect more storms to work with the heat and humidity to be more active tonight.

Morning rain and storms may cross metro Baltimore early. The the line will redevelop as it crosses Delmarva. The beach forecast for storms will be later in the evening.
