Possible severe weather for west Pasco Florida

Wha who! tomorrow is looking good for some severe weather!
Its been so long, I am so excited! Just saw this on NOAA....
A DEVELOPING STORM SYSTEM WILL MOVE ACROSS THE SOUTHEASTERN STATES
TONIGHT THEN UP ALONG THE MID ATLANTIC COAST ON SUNDAY. A TRAILING
COLD FRONT FROM THIS STORM SYSTEM WILL MOVE INTO THE EASTERN GULF
WATERS EARLY ON SUNDAY THEN ACROSS WEST CENTRAL AND SOUTHWEST FLORIDA
SUNDAY AFTERNOON AND EVENING. INCREASING LOW LEVEL MOISTURE ALONG
AND AHEAD OF THE FRONT WILL INCREASE CHANCES FOR SHOWERS AND STORMS
AS THE FRONT MOVES THROUGH THE REGION. INCREASING LOW AND MID LEVEL
WIND FIELDS AND STRONG UPWARD LIFT ALONG AND AHEAD OF THE FRONT SUGGESTS
THE POSSIBILITY OF SOME STRONG TO SEVERE STORMS WITH DAMAGING WINDS...
ISOLATED TORNADOES...OR MARINE WATERSPOUTS THE PRIMARY HAZARDS IF
ENOUGH INSTABILITY CAN DEVELOP OVER THE REGION.
I am going to borrow a friends camera, since I am still with out one. Depending on the time of its arrival i am hoping to catch it coming in off the water. If you happen to read this tonight keep you fingers crossed for me.

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.
