DISCUSSION…
A WARM FRONT NEAR THE RED RIVER THIS MORNING WILL LIFT NORTHWARD
ACROSS EASTERN OKLAHOMA AND NORTHWEST ARKANSAS TODAY…RETURNING A
WARM AND MOIST AIRMASS TO THE AREA. SHOWERS AND ISOLATED
THUNDERSTORMS ARE ONGOING THIS MORNING IN RESPONSE TO THE WARM AIR
RETURN. SEVERE WEATHER IS NOT EXPECTED WITH THESE THUNDERSTORMS.
AS THE WARM FRONT LIFTS NORTHWARD…GUSTY SOUTHERLY WINDS WILL
DEVELOP ACROSS THE AREA TOWARD MIDDAY. THE GUSTY WINDS WILL
PROVIDE FOR A LIMITED FIRE DANGER…ALTHOUGH HIGH RELATIVE
HUMIDITIES WILL LIMIT THE OVERALL THREAT.
DURING THE MID TO LATE AFTERNOON…ADDITIONAL THUNDERSTORMS ARE
EXPECTED TO DEVELOP ACROSS THE AREA IN RESPONSE TO AN APPROACHING
COLD FRONT. MODEST INSTABILITY AND STRONG WIND SHEAR WILL ALLOW
FOR AN ELEVATED THREAT OF SEVERE THUNDERSTORMS…INCLUDING THE
POSSIBILITY OF TORNADOES. THE MAIN THREATS…HOWEVER…WILL BE
LARGE HAIL AND DAMAGING WINDS. HEAVY RAIN MAY ALSO OCCUR IN THE
STRONGER STORMS. THE SEVERE THREAT IS EXPECTED TO WANE DURING THE
LATE EVENING AS THE INSTABILITY DECREASES.
THE AFOREMENTIONED COLD FRONT WILL ENTER PORTIONS OF NORTHEAST
OKLAHOMA BY MID EVENING…SWEEPING THROUGH MOST OF THE AREA BY
THANKSGIVING MORNING…BRINGING MUCH COLDER AIR AND NORTHERLY
WINDS GUSTING TO 35 MPH. MOST OF THE PRECIPITATION ASSOCIATED WITH
THIS STORM SYSTEM WILL OCCUR AHEAD OF THE COLD FRONT…HOWEVER…A
TRANSITION FROM RAIN TO FREEZING RAIN WILL BE POSSIBLE AFTER
MIDNIGHT IMMEDIATELY BEHIND THE FRONT ACROSS PORTIONS OF FAR
NORTHEAST OKLAHOMA AND FAR NORTHWEST ARKANSAS. LIGHT ICE
ACCUMULATIONS ON EXPOSED SURFACES WILL BE POSSIBLE…ALTHOUGH
ROADS ARE NOT EXPECTED TO BECOME IMPACTED DUE TO THE RECENT
UNSEASONABLY WARM WEATHER.
SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT…
ACTIVATION OF THE REGIONAL SPOTTER NETWORK LIKELY.
.DAYS TWO THROUGH SEVEN…THURSDAY THROUGH TUESDAY.
THURSDAY…WINTER WEATHER POTENTIAL…HIGH WIND POTENTIAL.
FRIDAY AND SATURDAY…NO HAZARDS.
SUNDAY…HIGH WIND POTENTIAL.
MONDAY AND TUESDAY…NO HAZARDS.
EXTENDED DISCUSSION…
LIGHT PRECIPITATION IS EXPECTED TO BE ONGOING THANKSGIVING
MORNING ACROSS AREAS TO THE SOUTHEAST OF THE INTERSTATE 44
CORRIDOR. SURFACE TEMPERATURES WILL BE COLD ENOUGH ACROSS PARTS OF
NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS TO SUPPORT FREEZING RAIN
THROUGH THE MORNING HOURS. WINDS ARE ALSO EXPECTED TO REMAIN GUSTY
DURING THE DAY DUE TO THE COLD FRONTAL PASSAGE.
