Interesting scenario shaping up for FL today. Currently a tornado watch for some of northern FL with likelihood of other watches to follow because of increased instability with upper trough and low pressure moving NNE--particularly notable will be the winds backing at lower levels S to SE early on then veering from S to SW during the day. Slight risk for entire state. Forecast mode to be some discrete cells before
MCS might develop in form of squall line with bowing segments.


We'll see what actually occurs and how the daytime heating goes. Local Mets have gotten relatively excited about the potential for rotating storms by mid-late afternoon with some of the cells in front of the line maybe being supercells. Don't think currently we can get too excited about that but looks like squall line will be a factor, and you can see that offshore/onshore though not too meaty so far. Early still but up to 650 helicity in N. FL--moisture remains in question (poor SB CAPE currently), yet models suggest it will arrive.

Shuttle landing is in question because of rising winds sustained winds 15-25. 1:19 PM is scheduled landing at Kennedy Space Center; they will either delay a day or aim for CA.

Well, the tornado watch has been expanded--a new one set up for further south into central Fl, though leaving out Melbourne unfortunately. You can see the squall line starting to shape up with an observable bow out there off the West Coast. Downbursts are expected to be a factor today. Might not see action out in the Eastern and central sections till after dark. Hopefully will see something worth photographing. Sun is shining amid the lower level clouds racing through currently. Still no CAPE to speak of.

Woke up this morning to a stiff breeze; additionally, we have had to turn on the air conditioning due to the high humidity. A tornado watch red box was issued for Hillsborough Cty & most of our northern counties. There are also strong lines of convection in progress heading towards our location. I love these stormy days!
