LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
ISSUED AT 121 AM CDT SUN OCT 11 2026
TUESDAY NIGHT THROUGH SATURDAY
ASSESSMENT...A CERTAINTY (>95%) OF A COOL DOWN. MEDIUM (40-60%)
CONFIDENCE REGARDING RAIN CHANCES.
A DEVELOPING TROPICAL CONNECTION WITH THE GULF AND THE REMNANTS OF
RACHEL WILL BRING SURGES OF MOISTURE INTO THE AREA; THE FIRST
TUESDAY NIGHT INTO WEDNESDAY AND THE SECOND AROUND THURSDAY.
TRENDS WITH THE MODELS ARE SHUNTING THE FIRST SURGE OF MOISTURE TO
THE SOUTH AND EAST OF THE AREA DUE TO A FRONTAL PASSAGE THAT
OCCURRED MONDAY NIGHT. THUS THERE IS A VERY REAL POSSIBILITY THAT
TUESDAY NIGHT/WEDNESDAY MAY END UP BEING DRY FOR MUCH OF THE AREA.
THE MOISTURE SURGE CENTERED AROUND THURSDAY IS STRONGER SO THIS MAY
END UP BEING THE BETTER CHANCE FOR RAIN. THE MODEL CONSENSUS HAS A
55-70 PERCENT CHANCE FOR RAIN CENTERED AROUND THURSDAY.
A MORE SIGNIFICANT COLD FRONT WILL SWEEP THROUGH THE AREA FRIDAY
NIGHT BRINGING BELOW NORMAL TEMPERATURES FOR NEXT WEEKEND.
ALTHOUGH THE GLOBAL MODELS HAVE BACKED OFF A LITTLE WITH THE
COLDER TEMPERATURES, THE PROSPECTS FOR THE FIRST FROST APPEAR TO
BE ON THE INCREASE ESPECIALLY NORTH OF I-80.
