Awesome. Hoping for some severe weather now that I have my camera to film it.

Not too severe, don't want any one hurt, just enough to make some sweet footage.

It's supposed to lose energy the closer it gets.

That forecast is a good one if you ask me. But remember, the severity of storms like this are extremely unpredictable and isolated. I wouldn't be surprised to see some tornado watches as far south as Hardee.

bouy 29.78 falling fast

The line of thunderstorms is holding intensity with
red visible on base reflectivity http://www.srh.noaa.gov/tbw
Warm tropical air advection ahead of the Low
pressure area is leading to showers and storms
out ahead of the main line. The line itself looks intense
and does appear from the "bow" shape of it to contain
wind gusts in the 40-50 mph range. Go to the velocity radar
at the base velocity level, and observe regions of 45 kt winds
and higher pockets to 60 kt within. Last Saturday I noticed the 60+
kt color and sure enough, Sunday morning, clearwater got 78 mph
(68 knot) winds.

These velocity radars do not lie.

Click on base velocity .50: Dark Blue color indicates 64 kt + winds that is
75 mph winds at the Southeast front of the squall line, about 100 miles
off the west coast of florida!

that convective line is holding its own as it approaches the coast. it looks like it is targeting the same area that got the worst of ex olga. based on radar trends the area first in line would be the region from about homosassa to clearwater/ indian rocks beach. the line then seems to string out more east west so a later southward advancedment down toward bradenton appears likely. this thing is moving too... the special marine warning issued by the nws mentions 50 knots while a meso disco from the spc mentions 40 knots. the latter also states to expect this to die off once over the peninsula. it will be interesting to see if this can maintain present intensity as it traverses the very cold waters within 20 miles or so of the coast... if it can i suspect areas from southern citrus county south to mid pinellas county could get a pretty good blast. since that's my backyard i am interested. btw bay news 9 radar has been showing some rotation this evening within portions of the line

The winds weakened before hitting my area. I saw what I estimate as gusts to
near 40 mph for about a few minutes just after 3 AM this morning.
