SHORT TERM
(THROUGH TONIGHT )
ISSUED AT 1134 AM CDT MON OCT 26 2026
PERSISTENT UPPER LEVEL RIDGING OVER THE SOUTHEAST CONUS AGAIN
TODAY, WITH A LONGWAVE TROUGH IN THE WEST. THIS CONTINUES THE RUN
OF DRY CONDITIONS WITH ABOVE NORMAL TEMPERATURES. A FAIRLY ROBUST
SHORTWAVE CENTERED NEAR KELP IS EXPECTED TO SLOWLY MOVE
NORTHEAST, WITH STEERING FLOW DIRECTING MOST OF IT'S ENERGY WELL
TO THE NORTHWEST OF THE LOCAL AREA.
LONG TERM
(TOMORROW THROUGH MONDAY)
ISSUED AT 1134 AM CDT MON OCT 26 2026
WE WILL SEE A SOLID INCREASE IN MID LEVEL MOISTURE TONIGHT INTO
TUESDAY AND THE UPPER RIDGE IS AT LEAST FLATTENED BY THIS
SHORTWAVE, BUT SURFACE PATTERN CONTINUES TO SUPPORT DRY LOWER
LEVELS. THERE WILL LIKELY BE JUST ENOUGH FORCING ACROSS THE
NORTHWEST PORTIONS OF THE AREA FOR SOME LIGHT PRECIP TO DEVELOP,
BUT WITH A LINGERING DRY LAYER NOTED BELOW ABOUT 800MB. SO AT
BEST, WOULD EXPECT SOME VERY LIGHT RAIN MAINLY TO THE WEST OF
HIGHWAY 75 TUESDAY, POTENTIALLY A FEW SPRINKLES TOWARD THE I-44
CORRIDOR. CLOUDS TUESDAY SHOULD BRING DAYTIME TEMPS DOWN A FEW
DEGREES. SLIGHTLY STRONGER FLOW OVER THE ROCKIES WILL TIGHTEN THE
PRESSURE GRADIENT BY MID WEEK, WITH A MODEST INCREASE IN WIND
SPEEDS RESULTING IN AN UPTICK IN FIRE WEATHER CONDITIONS WED,
THOUGH NOTHING NEAR CRITICAL.
MOST LONGER RANGE GUIDANCE CONTINUES TO DEPICT A GRADUAL
BREAKDOWN OF THE UPPER RIDGE AND A STRONGER MORE PERSISTENT
SOUTHWEST FLOW ALOFT DEVELOPING FOR OUR REGION. SURFACE PATTERN
SHOULD ALSO SUPPORT SOME INFLUX OF LOW LEVEL MOISTURE. THIS WILL
ULTIMATELY RESULT IN HIGHER RAIN CHANCES BY THE END OF THE WEEK
INTO THE WEEKEND, WITH A SLIGHT COOL DOWN OWING MAINLY TO MORE
CLOUD COVER AND PRECIP VERSUS ANY MEANINGFUL AIRMASS CHANGE.
FORECAST CONTINUES TO SHOW SOME RAIN CHANCES IN THE FRI-MON TIME
FRAME, MAINLY DUE TO THE UNCERTAINTY OF TIMING ANY SHORTWAVE IN
THE MORE UNSETTLED PATTERN.
