NATIONAL WEATHER SERVICE SAINT LOUIS MO
559 AM CDT FRI APR 10 2026
A COLD FRONT WILL MOVE SLOWLY ACROSS THE AREA TODAY. SCATTERED
SHOWERS AND A FEW THUNDERSTORMS WILL CONTINUE ALONG AND SOUTH OF
THE FRONT TODAY AND INTO THIS EVENING. COOLER AIR AND RAIN WILL
KEEP THE RELATIVE HUMIDITY WELL ABOVE 50 PERCENT IN MOST
LOCATIONS TODAY. THE FRONT WILL DRIFT BACK TO THE NORTH ON
SATURDAY ALLOWING SOME WARMER AIR TO MOVE BACK INTO THE REGION.
HOWEVER THE RELATIVE HUMIDITY WILL REMAIN HIGH, AND ONLY SOME
PARTS OF THE EASTERN OZARKS WILL DROP BELOW 45 PERCENT. SEVERAL
ROUNDS OF SHOWERS AND THUNDERSTORMS ARE EXPECTED SUNDAY THROUGH
NEXT THURSDAY. THIS WILL TEND TO KEEP AFTERNOON RELATIVE HUMIDITY
ABOVE 40 PERCENT IN MOST LOCATIONS.
