Thursday-Friday...A large and energetic trough will swing across the
eastern CONUS and Florida late this week, bringing an increasing
likelihood of showers and storms. A weak cold front is also forecast
to cross the Central FL peninsula late Thursday into Friday morning.
Models indicate moisture substantially increases Thursday with PWATs
of 1.6-1.8" or possibly greater, providing plenty of fuel for
numerous showers and lightning storms.

Rain chances have been bumped up to 60 percent areawide on Thursday,
with convection likely to linger into the evening hours until the
front moves through. Additionally, thermodynamic parameters and
favorable steering level winds will lead to few strong storms, with
small hail and gusty winds possible.

Drier air clears out any lingering showers across the I-4 corridor
by sunrise on Friday, though likely won`t clear the entire area
until late Friday afternoon. Isolated showers and perhaps a lightning
storm or two will be possible along the Space and Treasure Coasts,
where rain chances of 20-30 percent remain in place for Friday.
