.DISCUSSION...

...Continued Hot and Humid Across East Central Florida Today...
...Shower and Storm Chances Increasing this Weekend and into Early 
Next Week...

Currently...Ingredients remain in place for development of afternoon 
storms after we reach over 100 degrees heat index by midday. The 
present forecast was updated earlier this morning to include the 
Heat Advisory for Lake County and to bump up storm coverage around 
10 percent across the board. Inland areas will see the best chance 
of storm development by mid afternoon with rather weak steering and 
numerous boundary interactions. Locally heavy rain will be possible 
in the setup, along with the usual threats of frequent lightning and 
storm gusts of 40 to 50 mph in the stronger cells. SPC has listed a 
small area for marginal risk of severe storms west of the I-4 
corridor this afternoon. 

prev disc...

Today-Tonight...With mean winds blo 10KTS, both east and west coast 
sea breezes should from by midday, though inland progression will be 
slow. Low/mid lvl steering flow has become more normal to the east 
FL coast, which will allow the east coast seabreeze to dvlp by 
midday, though inland progression will be slow. This flow regime 
tends to focus diurnal precip over the west and southwest portions 
of the peninsula.
