KEY MESSAGES

BUT WITH MILDER AIR ARRIVING.
- DRY CONDITIONS ARE FORECAST FROM WEDNESDAY INTO THE UPCOMING
WEEKEND.
NEAR TERM
(TONIGHT)
ISSUED AT 230 PM CST SUN FEB 1 2026
A WEAK UPPER LEVEL DISTURBANCE MOVING SOUTHEASTWARD OVER THE
NORTHERN PLAINS WAS BRINGING MID AND HIGH ALTITUDE CLOUDS ACROSS
THE REGION. THOSE CLOUDS HAVE SLIGHTLY ATTENUATED THE MAXIMUM
POTENTIAL HEATING FROM THE SUN. STILL AREA TEMPERATURES SO FAR
HAVE RISEN INTO THE LOWER TO MID 30S. SURFACE HIGH PRESSURE OVER
THE TX/LA GULF COAST SHOULD CONTINUE BUILDING MORE TO THE EAST,
THEN SE ON MONDAY TONIGHT. THE PROXIMITY OF THAT HIGH TO THIS AREA
SHOULD RESULT IN LIGHT AND VARIABLE WINDS TONIGHT.
ALTHOUGH THE AIRMASS WAS MODERATING, WE CAN EXPECT ANOTHER COLD
NIGHT. LOW TEMPERATURES BY THE START OF MONDAY SHOULD FALL INTO
THE UPPER TEENS TO LOWER 20S. LIGHT WINDS AND TEMPERATURES NOT AS
COLD WILL BE WELL ABOVE A NEED FOR MORE COLD WEATHER ADVISORIES.
SHORT TERM
(MONDAY THROUGH TUESDAY NIGHT)
ISSUED AT 1100 AM CST SUN FEB 1 2026
DRY CONDITIONS WILL CONTINUE FOR THE START OF A NEW WORK WEEK.
UNDER PARTLY CLOUDY SKIES, HIGH TEMPERATURES SHOULD RISE INTO THE
MID 40S TO AROUND 50. LIGHT WINDS IN THE MORNING SHOULD BECOME
WESTERLY 5-10 MPH IN THE AFTERNOON.
CLOUDS WILL BE ON THE INCREASE MONDAY NIGHT, AS YET ANOTHER AND
STRONGER SYSTEM NEARS FROM THE WEST. THIS NEXT SYSTEM WILL BRING
MORE CHANCES OF SHOWERS TO THE VALLEY BEGINNING TUESDAY MORNING.
THE PRECIPITATION COULD START AS A BRIEF RAIN/SNOW MIX WHEN IT
STARTS, BUT WILL BECOME ALL LIQUID AS WE GO INTO THE DAY AND
TUESDAY NIGHT. DESPITE THE CLOUDS AND RAIN CHANCES, HIGH
TEMPERATURES TUESDAY SHOULD RISE INTO THE MID 50S. A COLD FRONT
WITH THE SYSTEM SHOULD MOVE ACROSS THE AREA LATE TUESDAY NIGHT,
RESULTING IN THE SHOWERS ENDING FROM WEST TO EAST. LOWS SHOULD
FALL INTO THE LOW/MID 30S. RAINFALL TOTALS ACROSS THE AREA SHOULD
RANGE AROUND 1/3 OF AN INCH.
LONG TERM
(WEDNESDAY THROUGH SATURDAY)
ISSUED AT 813 PM CST SAT JAN 31 2026
ON WEDNESDAY A COLD FRONT WILL BE PUSHING SOUTHEASTWARD THROUGH
PORTIONS OF AL AND INTO GA BRINGING AN END TO THE LIGHT RAIN FROM
OVERNIGHT. WITH AN UPPER LEVEL TROUGH DIGGING INTO THE SOUTHEAST
DURING THE MIDDLE OF THE WEEK, WE REMAIN ON THE COOLER SIDE WITH
AFTERNOON HIGHS IN THE LOWER 40S BOTH WEDNESDAY AND THURSDAY.
OVERNIGHT LOWS WILL BE CHILLY IN THE LOWER 20S, ESPECIALLY WEDNESDAY
NIGHT WHEN WINDS GUSTING 15-20 MPH AT TIMES BRINGING WIND CHILLS DOWN
INTO THE LOWER TEENS. HOWEVER, BY FRIDAY THIS TROUGH WILL LIFT TO
THE NORTHEAST KEEPING BOTH THE COLD AIR AND THE PRECIP WELL TO OUR
NORTH. WEAK RIDGING WILL SLOWLY BUILD INTO THE TENNESSEE VALLEY ON
FRIDAY AND SATURDAY, BUT NORTHWEST FLOW ALOFT WILL LIMIT ANY MASSIVE
WARMUP. THAT BEING SAID, AFTERNOON HIGHS FRIDAY AND SATURDAY RETURN
TO THE UPPER 40S TO LOWER 50S, WHICH IS NEAR CLIMATOLOGICAL NORMALS
FOR THIS TIME OF YEAR.
