SHORT TERM
(TODAY)
ISSUED AT 1204 AM CDT THU OCT 30 2025
WINDS HAVE DRASTICALLY SUBSIDED ACROSS EASTERN OK AND MUCH OF
NORTHWEST AR FROM EARLIER THURSDAY AFTERNOON. NORTHWEST WINDS
CURRENTLY REMAIN SOMEWHAT BREEZY AND OCCASIONALLY GUSTY OVER THE
HIGHER TERRAIN AREAS OF NORTHWEST AR AND SOUTHEAST OK, BUT WINDS
WILL CONTINUE TO TREND DOWN AS THE OVERNIGHT AND EARLY MORNING
PROGRESSES. LATEST IR SATELLITE IMAGERY SHOWS CLOUD COVER SLOWLY
TRYING TO CLEAR FROM WEST TO EAST AS THE UPPER-LEVEL LOW CONTINUES
TO SHIFT EASTWARD OVER TN. CLEARING SKIES AND RELATIVELY LIGHT WINDS
SHOULD YIELD IN THE DEVELOPMENT OF PATCHY FROST EARLY THIS MORNING,
BEST OVERALL CONDITIONS OCCURRING WEST OF HIGHWAY 75 IN NORTHEAST OK
WHERE TEMPERATURES ARE FORECAST TO DROP BETWEEN 33 AND 36 DEGREES BY
SUNRISE. A FROST ADVISORY REMAINS IN EFFECT FOR LOCATIONS WEST OF
HIGHWAY 75 FROM 3 AM TO 9 AM. LIGHT, PATCHY FROST MAY ALSO BRIEFLY
OCCUR IN HILLY AND HIGHER TERRAIN AREAS OF NORTHWEST AR AND
SOUTHEAST OK.
BEYOND THE FROST POTENTIAL, THE REMAINDER OF THE DAY IS EXPECTED TO
BE VERY PLEASANT AND UNSEASONABLY COOL, UNDERNEATH PARTLY CLOUDY TO
MOSTLY SUNNY SKIES AND LIGHT NORTHERLY WINDS, AS A SURFACE RIDGE
AXIS SLIDES INTO THE AREA BY THIS AFTERNOON. AFTERNOON HIGH
TEMPERATURES WILL RANGE FROM THE MID-UPPER 50S TO NEAR 60 DEGREES
NORTH OF I-40 AND LOWER 60S SOUTH OF I-40.

LONG TERM
(TONIGHT THROUGH WEDNESDAY)
ISSUED AT 1204 AM CDT THU OCT 30 2025
OVERALL, ANTICIPATE MAINLY LOW-IMPACT WEATHER TO PREVAIL THROUGH THE
LONG-TERM PERIOD. SURFACE HIGH PRESSURE WILL ANCHOR ITSELF ACROSS
EASTERN OK AND WESTERN AR LATE TONIGHT AND INTO FRIDAY MORNING. THIS
SHOULD RIPEN FROST CONDITIONS FOR A MUCH WIDER AREA COMPARED TO THIS
MORNING AS TEMPERATURES FALL INTO THE MID-UPPER 30S AREAWIDE. WILL
FORGO ISSUING A FROST ADVISORY AT THIS TIME, BUT ONE WILL LIKELY BE
NEEDED FOR MUCH OF THE FORECAST AREA TONIGHT. NORTH/NORTHWEST UPPER-
LEVEL WINDS WILL BECOME MORE ZONAL BY FRIDAY AFTERNOON AS THE NEXT
UPPER-LEVEL LOW/TROUGH DROPS OVER THE UPPER MIDWEST REGION.
DETERMINISTIC AND ENSEMBLE MODEL DATA CONTINUE TO VARY IN SOLUTIONS
REGARDING THE EVOLUTION AND TRACK OF THIS SYSTEM. MOST MODELS SHOW A
WEAK FRONTAL BOUNDARY PUSHING THROUGH SATURDAY MORNING/AFTERNOON,
WITH LIGHT-MODERATE RAIN ALONG THE BOUNDARY/TROUGH AXIS. BECAUSE OF
HIGH UNCERTAINTY WITH REGARDS TO THE TRACK OF THE UPPER-LEVEL LOW,
WILL LEAVE NON-MENTIONABLE POPS (BELOW 15%) IN THE FORECAST ON
SATURDAY. HOWEVER, DESPITE PWATS REMAINING LESS THAN AN INCH,
CONFIDENCE IS INCREASING THAT AT LEAST A MENTION OF LOW POPS WILL
NEED TO BE ADDED OVER THE NEXT COUPLE OF FORECAST PACKAGES,
ESPECIALLY ACROSS SOUTHEAST OK AND NORTHWEST AR WHERE PWATS WILL BE
HIGHEST.
AS THE UPPER-LEVEL LOW OVER THE MIDWEST DIVES SOUTHWARD TOWARDS THE
NORTHERN GULF COAST SUNDAY AND INTO EARLY NEXT WEEK, MID/UPPER-LEVEL
RIDGING WILL BEGIN TO BUILD OVER THE SOUTHERN PLAINS. TEMPERATURES
WILL TREND WARMER, RISING A FEW DEGREES ABOVE SEASONAL AVERAGE BY
TUESDAY, WITH RAIN CHANCES LOOKING UNLIKELY THROUGH MID WEEK.

CORRIDOR OF LOW VFR TO PERIODIC MVFR CEILINGS CURRENTLY EXTENDS
ACROSS THE LOCAL REGION. EXPECTATION IS THAT CEILINGS WILL ERODE
OVERNIGHT AND SATELLITE TRENDS DO SUGGEST THAT TREND IS UNDERWAY,
HOWEVER TIMING MAY SLIGHTLY LONGER THAN SHORT TERM GUIDANCE WOULD
SUGGEST. ONCE CLOUDS CLEAR, LIGHT WINDS AND VFR CONDITIONS AREA
WIDE THROUGH THE FCST PERIOD.
