President's day/wet weather

Has any one notice how active the weather has been in the last five years, record breaking events every year. Now supercells lasting longer then expected, baffling experts from all over.
Just a thought.
As you can see from the picture above we have some rain coming are way thunderstorms are expected for us: ENOUGH
MID AND LOW LEVEL SHEAR WILL BE PRESENT OVER NORTHERN FLORIDA AND
SOUTHERN GEORGIA EARLY TODAY THAT A FEW STRONG STORMS MAY DEVELOP
FROM TAMPA BAY NORTHWARD. THE STRONGEST STORMS MAY PRODUCE WIND
GUSTS UP TO 45 MPH...ALONG WITH VERY HEAVY RAINFALL.
Yesterday the Florida panhandle and southern Alabama had there share of severe weather
DEWDROP and JEFF GAMMONS blog has some great reports. Good Job guys!! True weather geeks!
My hero's!!
I will be keeping an eye the radar but for the most part this will be a rain event but you never know.
Have a good Monday and a good week!
Jess

HAIL (3/4 inch or greater)

Hail can cause significant damage to your vehicle, break windows and damage roofs of homes and businesses.
Hail can cause significant bodily injuries such as broken bones and even blindness if wind blown.
Softball (4.5 inches) sized hail was reported in Lake Wales, Florida on March 30, 1996.
Haildrifts, up to four feet deep of dime to nickel sized hail, occurred in low-lying areas near Zephyrhills, Florida on January 29, 1997.
Hailstones the size of softballs can fall at speeds faster than 100 mph

supercell

Supercells derive their rotation through tilting of horizontal vorticity (an invisible horizontal vortex) caused by wind shear. Strong updrafts lift the air turning about a horizontal axis and cause this air to turn about a vertical axis. This forms the deep rotating updraft, the mesocyclone.
A cap or capping inversion is usually required to form a downdraft of sufficient strength. The cap puts an inverted (warm-above-cold) layer above a normal (cold-above-warm) boundary layer, and by preventing warm surface air from sinking too far, allows one or both of the following:
Air below the cap warms and/or becomes more moist
Air above the cap cools
This creates a warmer, moister layer below a cooler layer, which is increasingly unstable (because warm air is less dense and tends to rise). When the cap weakens or moves, explosive development follows.
In North America, supercells usually show up on Doppler radar as starting at a point or hook shape on the southwestern side, fanning out to the northeast. The heaviest precipitation is usually on the southwest side, ending abruptly short of the rain-free updraft base or main updraft (not visible to radar). The rear flank downdraft, or RFD, carries precipitation counterclockwise around the north and northwest side of the updraft base, producing a "hook echo" that indicates the presence of a mesocyclone.
