Severe Thunderstorms Probable Today

[Thomas F. Giella NZ4O]

The 8:00 am EDT NWS Tampa Bay (KTBW) radiosonde launch found a (PW) 
precipitable water of 1.94", a (LI) lifted index of -10 deg. C, which is 
extremely unstable and an (MPDI) Microburst-Day Potential Index of +1.4, 
which means allot dry mid level air.

This ads up to a probability of severe weather to include rainfall rates of 
 >2" per hour, down bursting straight line winds in excess of 60 mph and 
large damaging hail to 1" in diameter. Isolated tornadoes are also possible 
where sea breeze and outflow boundaries collide.

Lightning is not considered as a severe weather parameter but with a 500 mb 
temperature of -10 deg. C, excessive numbers of lightning strikes are 
probable.

Movement of storms will be from the NNW to SSE.
