Sunday Afternoon July 12 2020

We have ourselves a more comfortable day with respect to humidity, but it’s still hot. Plenty of stations reported 90ºF temperatures. Add in a cold front and there is enough energy to produce widespread showers and thunderstorms.

Radar Update (see below): As of this post at 3 PmM some showers developed on the west side of Baltimore. In PG County there is a cell that may reach Annapolis close to 4 PM. A larger cluster near Hagerstown and down I-81. The peak activity will be between 4 and 7 PM, but the chance for rain and lightning will continue through 11 PM.

I wanted to give you the tools to make your judgment call for your plans to stay out or head in early.  Below is a look at the satellite and radar loops.  Then two model simulation sliders. I feel like a broken record, but three models have underestimated the flare of up storms. They have verified a little earlier and more widespread. But here is a look at the timing for the germinal activity through this evening.


Satellite Loop:

Clouds have bubbled up in the past few hours and there is still a little more heating to feed into more storms.




Radar Loop

Time frame: 1:35 PM to 3 PM

Simulations Starting at 4 PM

Here you can see there has been more activity one hour earlier that projected. But compare the models to see how they are behaving through the evening for your area.
