AREAS AFFECTED...SOUTHEAST OK/NORTHERN AR/FAR SOUTHERN MO/FAR
NORTHERN TN/MUCH OF KY INTO SOUTHERN IL/INDIANA AND WV

CONCERNING...FREEZING RAIN

VALID 271206Z - 271700Z

SIGNIFICANT FREEZING RAIN /AND SOME SLEET/ WILL CONTINUE TO OCCUR
WITHIN A SW-NE ORIENTED/75-100 MILE WIDE CORRIDOR FROM SOUTHEAST
OK/NORTHERN AR/FAR SOUTHERN MO INTO MUCH OF KY AND ADJACENT PORTIONS
OF FAR NORTHERN TN AND FAR SOUTHERN IL/INDIANA INTO SOUTHERN WV/FAR
SOUTHERN OH. THIS INCLUDES AREAS FROM MCALESTER OK TO FT
SMITH/JONESBORO AR TO EVANSVILLE INDIANA AND PADUCAH/BOWLING
GREEN/LEXINGTON KY. WIDESPREAD LIQUID-EQUIVALENT RATES OF 0.05 TO
0.15 IN/HR...LOCALLY EXCEEDING 0.30 IN/HR...WILL RESULT IN CONTINUED
SIGNIFICANT ICE ACCUMULATIONS.

ISENTROPIC ASCENT COINCIDENT WITH SURFACE-850 MB BAROCLINIC ZONE IS
EXPECTED TO MAINTAIN CONSIDERABLE PRECIPITATION RATES IN A CORRIDOR
FROM SOUTHEAST OK TO MUCH OF KY THROUGH EARLY AFTERNOON. LATEST SREF
P-TYPE GUIDANCE AND INTERPOLATED 12Z RAOB NETWORK
OBSERVATIONS/PERIPHERALLY AVAILABLE ACARS DATA AND LATEST RUC
FORECAST SOUNDINGS ALL SUGGEST FREEZING RAIN WILL REMAIN THE
DOMINANT PRECIPITATION TYPE ACROSS THIS CORRIDOR INTO EARLY
AFTERNOON...WITH SIGNIFICANT ICE ACCUMULATIONS LIKELY. THIS SCENARIO
IS GENERALLY CHARACTERIZED BY A WARM/MELTING LAYER AROUND 850 MB
ATOP A SHALLOW SUB-FREEZING AIRMASS AS MAINTAINED BY LOW LEVEL
NORTHEASTERLY TRAJECTORIES. THIS ZONE OF PRIMARILY FREEZING RAIN
SHOULD SPATIALLY FLUCTUATE LITTLE ACROSS NORTHERN AR/FAR SOUTHERN MO
THROUGH THE MORNING...BUT WARM ADVECTION ABOVE THE SURFACE SHOULD
SLOWLY SHIFT THE PRIMARY ZONE OF FREEZING RAIN NORTHWARD ACROSS
CENTRAL/EASTERN KY AND WV INTO FAR SOUTHERN INDIANA/OH INTO EARLY
AFTERNOON.
