A surface level low pressure area has developed south on Louisiana, with an upperlevel low forming further west.  The entire system is currently headingtoward the east. The first wave should bring much needed rain (1-3” canbe expected) to Central Florida with thechance of hail, high winds and isolated tornados later today.  Dependingon the timing of the upper level low, the energy from the upper level low couldbring with it a higher chance of severe weather later this evening into Sundaymorning as the system moves across the state from the Gulf to the Atlantic.

Saturday afternoon/evening:  Between 3:00 and 9:00 p.m. widespread rain, with embedded thunderstorms expected.Isolated thunderstorms may become strong/severe, with damaging winds, hail, andan isolated tornado possible.  Average rainfall totals through midnight of1-2 inches, locally up to 3 inches in areas which receive multiple rounds ofheavy rain.

Sunday morning:  Asecond system will move in behind the first.  Expected to arrive after 12midnight and move across to the Atlanticbefore day break Sunday morning.  Evolution of this system is uncertain atthis time as the initial rain area this afternoon/evening may limit the abilityfor the second area to fully develop.  Ifthe complex of storms or squall line is able to form, a greater threat fordamaging wind gusts, hail, and tornadoes will exist during the late eveningthrough early morning hours Sunday.  Rain totals with thissecondary threat area will average 1-2 inches.
