STRAIGHT DAYS OF TEMPERATURES IN THE 90S WILL GIVE US JUST ONE MORE

USHERING IN SLIGHTLY COOLER AND LESS HUMID AIR. WHILE TEMPERATURES
MONDAY MAY APPROACH THE 90 DEGREE MARK IN SOME AREAS...THE HUMIDITY
WILL BE LOWER THAN IT HAS BEEN THE PAST WEEK. THAT WILL MEAN THAT

EFFECTIVELY ENDING OUR HEAT WAVE. A STRONGER COLD FRONT IS EXPECTED
TO CROSS THE AREA MONDAY NIGHT BRINGING THE POSSIBILITY FOR MORE
WIDESPREAD SHOWER ACTIVITY. COOLER AND DRIER AIR WILL FOLLOW
