MESOSCALE UPDATE
ISSUED AT 1003 AM CDT THU SEP 11 2025
WARMER THAN NORMAL TEMPERATURES AND DRY WEATHER IS EXPECTED
TODAY. THE VERY LIGHT AND PATCHY FOG THAT DEVELOPED EARLY THIS
MORNING HAS DISSIPATED. THERE IS AN UPPER LEVEL DISTURBANCE WELL
TO OUR NORTH PRODUCING SOME MID AND HIGH CLOUDS THAT OUR NORTHWEST
FLOW ALOFT MAY BRING INTO OUR CWA THIS AFTERNOON BUT STRONG
INSOLATION IS EXPECTED ACROSS MOST OF OUR CWA. /22/
DISCUSSION
ISSUED AT 1234 AM CDT THU SEP 11 2025
TODAY THROUGH TONIGHT:
UPPER AND SURFACE RIDGING WILL CONTINUE TO PREVAIL ACROSS THE AREA
TODAY AND THIS WILL CONTINUE THROUGH TONIGHT. THE UPPER RIDGE WILL
STRENGTHEN OVER THE AREA TODAY AND THIS WILL RESULT IN
TEMPERATURES BEING A COUPLE OF DEGREES HOTTER, RANGING FROM THE
LOW TO MID 90S. CLEAR SKIES WILL CONTINUE TONIGHT, WITH
POSSIBILITY OF SOME LIGHT PATCHY FOG. OVERNIGHT LOWS WILL MOSTLY
BE IN THE MID TO UPPER 60S./15/
THURSDAY NIGHT THROUGH TUESDAY NIGHT:
THURSDAY EVENING, THE OMEGA BLOCK WITH RIDGING OVER THE CENTRAL
CONUS AND TROUGHING OVER EAST AND WEST WILL STILL BE IN PLACE.
THIS PATTERN LOOKS TO LAST THROUGH EARLY NEXT WEEK EVEN AS THE
RIDGE AXIS SHIFTS TO BECOME CENTERED NEARLY OVER THE MISSISSIPPI
RIVER. THE SURFACE RIDGING FROM THE NORTHEAST WILL CONTINUE OVER
OUR REGION AS WELL. THIS WILL CONTRIBUTE TO A WARMING TREND
THROUGH THE PERIOD WITH HIGHS TOPPING OUT IN THE MID TO UPPER 90S
BY MONDAY. THE SURFACE RIDGE WILL CONTINUE TO HELP LIMIT MOISTURE
RETURN AND ALTHOUGH IT WILL BE HOT, THE LOWER RELATIVE HUMIDITY
WILL MITIGATE AND HEAT STRESS CONCERNS AS PEAK HEAT INDEX VALUES
LOOK TO REMAIN BELOW 105F. THE LATEST DROUGHT MONITOR SHOWED
ABNORMALLY DRY TO MODERATE DROUGHT CONDITIONS ACROSS OUR NORTHERN
ZONES. WITHOUT ANY RAINFALL IN THE FORECAST ALONG WITH THE HOT
TEMPERATURES, CONDITIONS ARE EXPECTED TO WORSEN. /22/
