NEAR TERM
(THROUGH FRIDAY)
ISSUED AT 1245 AM CDT FRI OCT 31 2025
THE HALLOWEEN FORECAST IS MORE 'TREAT' THAN 'TRICK' FOR OKLAHOMA AND
WESTERN-NORTH TEXAS TODAY. THE SURFACE (AND UPPER AIR) PATTERN
REMAINS RATHER BENIGN, WITH A DISSIPATING SURFACE HIGH ACROSS THE
WESTERN GULF COAST AND WEAK LEE CYCLONE DEVELOPING ACROSS THE
SANGRE DE CRISTO RANGE.
CLEAR SKIES AND LIGHT SURFACE WINDS WILL LEAD TO ANOTHER CHILLY
MORNING ACROSS THE REGION, WITH SUB-FREEZING TEMPERATURES EXPECTED
ACROSS PORTIONS OF NORTHERN AND CENTRAL OKLAHOMA. EVEN WHERE
TEMPERATURES REMAIN A FEW DEGREES ABOVE FREEZING, SUFFICIENT LOW-
LEVEL SATURATION IS ONGOING TO SUPPORT FROST FORMATION. THE PREVIOUS
FROST ADVISORY WILL BE MAINTAINED FOR PORTIONS OF CENTRAL AND
EASTERN OKLAHOMA UNTIL 9 AM THIS MORNING.
TEMPERATURES WILL WARM TOWARDS SEASONABLE READINGS (60S TO LOW-70S)
BY THE AFTERNOON WITH A LIGHT SOUTHEAST BREEZE. COVERAGE OF HIGH
CLOUDS WILL BE ON THE INCREASE TOWARDS TRICK-OR-TREATING TIME THIS
EVENING, WITH TEMPERATURES QUICKLY COOLING INTO THE 50S AFTER
SUNSET.

SHORT TERM
(FRIDAY NIGHT THROUGH SUNDAY NIGHT)
ISSUED AT 1245 AM CDT FRI OCT 31 2025
A QUICK-MOVING SURFACE FRONT WILL OFFER LOW CHANCES FOR RAIN SHOWERS
AND COOLER CONDITIONS ON SATURDAY. PRECIPITATION CHANCES WILL BE
FOCUSED DURING THE PREDAWN INTO MID-MORNING HOURS, MAINLY ALONG-EAST
OF THE I-35/44 CORRIDORS. MODELED VERTICAL PROFILES SHOW A
PRONOUNCED DRY LAYER BELOW CLOUD BASE SUCH THAT RAIN ACCUMULATIONS/IMPACT
ARE EXPECTED TO BE VERY LIMITED IN NATURE. A LIGHTNING
STRIKE/RUMBLE OF THUNDER OR TWO CANNOT BE RULED OUT AS WELL,
THOUGH WILL LIKELY OCCUR ON A VERY ISOLATED BASIS (IF AT ALL).
A COOL POST-FRONTAL AIRMASS WILL SETTLE BY THE AFTERNOON AND EVENING
ON SATURDAY, WITH HIGH CONFIDENCE IN DAYTIME TEMPERATURES REMAINING
IN THE 50S ACROSS PORTIONS OF NORTHERN AND NORTH-CENTRAL OKLAHOMA
(LOW-60S ELSEWHERE).
SUNDAY WILL BE A "WARMER" (AND DRY) DAY, AS STRONGER SOUTHERLY WINDS
COMMENCE AND A WARM LOW-LEVEL AIRMASS ADVECTS DOWNSTREAM OF A
WESTERN CONUS RIDGE. A WIDER PROFILE OF 70S ARE EXPECTED INTO THE
AFTERNOON, ESPECIALLY ACROSS WESTERN OKLAHOMA AND WESTERN-NORTH
TEXAS. CLEAR SKIES ARE ALSO LIKELY, PROVIDING FOR A GREAT FALL
WEATHER DAY.
UNGAR
LONG TERM
(MONDAY THROUGH THURSDAY)
ISSUED AT 1245 AM CDT FRI OCT 31 2025
A PERIOD OF GENERALLY LOW-IMPACT AND WARM WEATHER LOOKS TO RETURN
INTO NEXT WEEK. WHILE GRAND ENSEMBLE GUIDANCE HINTS AT A
POTENTIALLY ACTIVE POLAR JET DURING THIS TIME, AN EXPANDED
UPSTREAM RIDGE WILL LIKELY DEFLECT PASSING SYSTEMS TO THE
NORTH/EAST OF THE FORECAST AREA. FOR NOW, WE LOOK TO RETURN
TOWARDS ABOVE-NORMAL/MORE ATUMUN-LIKE WARMTH (70S TO LOW-80S) BY
MONDAY. DRY SURFACE CONDITIONS ARE CURRENTLY ADVERTISED FOR THIS
PERIOD AS WELL.
