DISCUSSION
ISSUED AT 1107 AM CST TUE JAN 20 2026
A MID/UPPER LEVEL SHORTWAVE MOVING EAST INTO THE SOUTHERN US HAS
BROUGHT LOW TO MEDIUM CHANCES RAIN TO THE REGION THROUGH WEDNESDAY
(20-50%) BEFORE DRYING OUT AGAIN WEDNESDAY NIGHT. TEMPERATURES
WILL REMAIN ABOVE NORMAL THROUGH FRIDAY.
THE MAIN STORY FOR THIS FORECAST CYCLE WILL BE A STRONG COLD
FRONT PUSHING THROUGH DEEP SOUTH TEXAS ON SATURDAY BRINGING MUCH
COLDER AIR. HIGH TEMPERATURES FOR THE DAY ON SATURDAY WILL BE A
LITTLE CLOSER TO SEASONAL NORMS BEFORE PLUNGING INTO THE 30S
OVERNIGHT WITH FEELS LIKE TEMPS IN THE TEENS AND 20S. THESE
OVERNIGHT TEMPERATURES WILL NEED TO BE WATCHED CLOSELY AS THIS
FRONT WILL BRING WITH A LOW CHANCE (20-30%) OF PRECIPITATION WITH
IT ON SATURDAY NIGHT. IF THE PRECIPITATION OR ANY WET SURFACES
COINCIDE WITH BELOW FREEZING TEMPS WE COULD SEE SOME LIGHT
FREEZING RAIN/ICING IN SPOTS (MAINLY ELEVATED SURFACES) IN THE
NORTHERN RANCHLANDS (<10% CHANCE). WILL CONTINUE TO CLOSELY
MONITOR THE POTENTIAL FOR ANY WINTRY PRECIPITATION. SUNDAY INTO
MONDAY WILL BE MUCH COOLER WITH HIGHS ONLY REACHING THE 40S AND
50S WITH OVERNIGHT LOWS IN THE 30S. FEELS LIKE TEMPS WILL BE IN
THE 20S AND 30S. THE OVERNIGHT COLD TEMPERATURES WILL LIKELY
WARRANT THE NEED FOR FREEZE WATCHES/WARNINGS AND COLD WEATHER
ADVISORIES SATURDAY NIGHT THROUGH MONDAY NIGHT. NOW IS THE TIME TO
PREPARE FOR FREEZING TEMPERATURES THIS WEEKEND. MAKE SURE TO
PROTECT PIPES, PETS, PLANTS, AND PEOPLE.
