OUT OF THE STATE AS A WARM FRONT BY THURSDAY. WEAK LOW PRESSURE MAY
REMAIN IN THE AREA OVER THE WEEKEND. MOISTURE LEVELS WILL REMAIN
HIGH AND THE AIR WILL REMAIN UNSTABLE.

ALTHOUGH NO SIGNIFICANT SEVERE WEATHER IS EXPECTED AT THIS TIME
THERE WILL BE A CHANCE OF ISOLATED STRONG TO SEVERE STORMS WITH
LARGE HAIL AND DAMAGING WIND THROUGH THE PERIOD. ALSO ISOLATED
HEAVY RAINS AND FLOODING WILL BE POSSIBLE.
