DISCUSSION
ISSUED AT 1233 AM CST FRI JAN 2 2026
OVERALL, THIS FORECAST LOOKS WARMER AND DRIER THAN NORMAL FOR THE
FIRST WEEK OF JANUARY. A QUICK-MOVING SYSTEM TODAY WILL STRUGGLE
TO GENERATE STORMS OR ANY SIGNIFICANT RAINFALL FOR OUR AREA DUE
TO THE LIMITED TIME FOR RETURN FLOW. THIS SYSTEM WILL BE FOLLOWED
BY WEAK POLAR HIGH PRESSURE AND A BRIEF COOL-DOWN BEFORE MORE
SIGNIFICANT WARMTH RETURNS WITH A BUILDING UPPER LEVEL RIDGE OVER
THE CENTRAL CONUS.
LOOKING AT THE DETAILS, SCATTERED SHOWERS AND STORMS SHOULD RETURN
THIS AFTERNOON AND EVENING IN THE WARM ADVECTION PATTERN. THUNDER
IS POSSIBLE, BUT NOT LIKELY IN MOST AREAS. ATOP THE RATHER
SHALLOW SURFACE MOISTURE, OWING TO LIMITED RESIDENCE TIME OVER
WATER OF THE INCOMING PREFRONTAL MOISTURE PLUME, A REMNANT CAPPING
INVERSION WITH POOR LAPSE RATES ABOVE WILL LIMIT SHOWER/STORM
COVERAGE IN THE AREAS WHERE THE BETTER COMBINATION OF SHEAR AND
INSTABILITY IS LIKELY. THIS WILL LIKELY PRECLUDE MEANINGFUL
UPGRADES IN THE RISK OUTLOOK BEYOND THE CHANCE FOR AN ISOLATED
STRONGER STORM OR TWO WITH WIND GUSTS UP TO 40 MPH.
THIS SYSTEM MOVES OUT OF OUR FORECAST AREA SUNDAY MORNING
BRINGING AN END TO RAIN CHANCES. QUIET CONDITIONS THEN ARE LIKELY
THROUGH MUCH OF NEXT WEEK AS SOUTHERLY FLOW MODERATES THE
TEMPERATURES TO WELL ABOVE EARLY JANUARY NORMALS - DAYTIME HIGHS
INTO THE 70S AND OVERNIGHT LOWS IN THE 50S FOR MID/LATE WEEK. THE
NEXT CHANCES FOR RAIN WILL LIKELY NOT ARRIVE UNTIL NEAR THE END OF
THE FORECAST PERIOD, BY LATE NEXT WEEK.
AVIATION
