TODAY
HIGH PRESSURE WILL BUILD ACROSS THE UPPER MISSISSIPPI RIVER
VALLEY TODAY. IT WILL PROVIDE DRY WEATHER FOR THE REGION. ANY
SHOWERS AND STORMS WILL BE ASSOCIATED WITH THE UPSTREAM TROUGH
IN THE OMEGA HIGH ACROSS WESTERN AND SOUTHERN IOWA. WITH THE
PASSAGE OF THE BACKDOOR COLD FRONT EARLIER THIS MORNING, HIGH
TEMPERATURES WILL RANGE FROM THE MID-70S TO MID-80S.
FRIDAY THROUGH TUESDAY
THE RIDGE ASSOCIATED WITH THE 500 MB OMEGA HIGH WILL BE LOCATED
ACROSS THE REGION. MEANWHILE, AT THE SURFACE, THERE WILL BE A
HIGH LOCATED OVER MICHIGAN. AS A RESULT, OUR WINDS WILL
PRIMARILY RANGE FROM THE NORTHEAST TO SOUTHEAST AT 5 TO 15 MPH.
THESE WINDS WILL CONTINUE TO BRING VERY DRY AIR INTO THE REGION.
WITH HIGH TEMPERATURES IN THE MID- TO UPPER 80S, RELATIVE
HUMIDITIES WILL FALL INTO THE 20S AND 30S EACH AFTERNOON. WITH
THE EXTENDED DRY AND UNUSUALLY WARM CONDITIONS, WE COULD
POTENTIALLY BE LOOKING AT THE BEGINNING OF A FLASH DROUGHT AND
THE POTENTIAL FOR ELEVATED FIRE WEATHER CONCERNS.
