1027 AM CDT MON MAR 23 2026
DISCUSSION
NORTH TO NORTHEASTERLY WINDS WILL REMAIN GUSTY THIS MORNING, BUT
WILL GRADUALLY DIMINISH THIS AFTERNOON AS HIGH PRESSURE BUILDS
ACROSS THE REGION. DRIER AIR WILL WORK ITS WAY INTO THE AREA TODAY,
WITH AFTERNOON RH VALUES FALLING INTO THE 25 TO 35 PERCENT RANGE
AWAY FROM THE IMMEDIATE INFLUENCE OF THE LAKE. A LAKE BREEZE WILL
DEVELOP AND SPREAD INLAND THIS AFTERNOON COOLING TEMPERATURES A
BIT, LOWERING MIXING HEIGHTS, INCREASING RH VALUES, AND SHIFTING
WINDS OUT OF THE EAST TO EAST-NORTHEAST. WINDS WILL BECOME
SOUTHERLY TUESDAY AND WEDNESDAY, WITH HIGH TEMPERATURES ABOUT 10
DEGREES WARMER EACH DAY. THURSDAY WILL BE BREEZY AND UNSEASONABLY
WARM AHEAD OF A STRONG COLD FRONT WHICH COULD BRING SOME SCATTERED
THUNDERSTORMS TO THE AREA DURING THE AFTERNOON AND EVENING.
BEHIND THAT COLD FRONT, LOOK FOR HIGH TEMPERATURES TO BE MUCH
COLDER FRIDAY. GRADUALLY MODERATING TEMPERATURES AND DRY
CONDITIONS ARE EXPECTED NEXT WEEKEND.
