Florida heat wave

It's only May and yes folks we are seeing temps reaching the 90's.
The drought is getting worse, Florida is 4.53 inches behind in rain already for the year. This is bad, and yes each day that goes by without rain is just making it worse.I read recently my county- Pasco is doing a good job with conserving our water.but that also means no fun in the hose for the kids this summer. Those of us without pools no how bad this sucks! While I'm here bitching about no rain five states,TX,LA,MS.Al.GA are getting pounded,storm after storm after storm. 30 Tornado's have been reported since Friday,and wide spread flooding hail storms and on
Saturday a severe thunderstorm warning went up at 3:06 pm in Dallas Texas At 3:30pm 70mph winds collapsed the Dallas Cowboy's practice facility. They are reporting that event as a MicroburstClick on Microburst to read how this event forms.
Scary stuff if you don't know whats going on weather wise around you. That's why a weather radio is an absolute necessity!! If you don't have one go out and get one before you become one of those people....you know what i mean.

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.
