Brian: Slow-moving storms again in today's forecast... not as hot...

Good morning! I just got started on the forecast and everything appears in line for cooler temperatures to move into southwest Florida over the next few days. As high pressure breaks down overhead, coupled with all the moisture in the ground from yesterday's heavy rain event, we should highs in the mid 90's today instead of upper 90's. By tomorrow and into the weekend, we're into the lower 90's -- sure, it's still hot, but seasonably so (remember, average high now is about 92!).

A weak trough is moving overhead aloft in the northern part of the state. The steering flow will be quite weak again this afternoon and there is the opportunity of showers and storms just about anywhere. However, I think we may see a slight bit more of inland push with the storms (at least initially late this afternoon) with a light westerly component to the steering flow. The currents remain quite weak again tomorrow before picking up more out of the northeast and east for the weekend -- this will mean a more steady push of storms to the beaches late in the day.

I'm still watching the potential for some tropical moisture to affect the area by Wednesday of next week. This will be associated with the old tropical wave (INVEST 92L) we were watching in the central Atlantic. This wave is no longer organized but still does have quite a bit of thunderstorm activity with it as it heads toward the northeast Caribbean. It'll be important to watch how well the t-storm activity is organized as it moves across the islands this weekend; that will give us some hint as to just how high our rain chance will be by mid-week.
