SOUTHWESTERLY WINDS TO AROUND 10 MPH AHEAD OF THIS FRONT, ALONG
WITH TEMPERATURES SURGING INTO THE LOW 90S. THE FRONT WILL PUSH
THROUGH THE AREA BETWEEN 3 AND 7PM THIS EVENING, AND AS IT PUSHES
THROUGH THERE WILL BE A 30% CHANCE OF A SHOWER OR THUNDERSTORM. IN
ADDITION TO ANY RAIN THESE STORMS COULD BRING, STORMS MAY ALSO
BRING STRONG WIND GUSTS AND HAIL TO AROUND AN INCH IN DIAMETER.
