THE SECOND ROUND OF THUNDERSTORMS IS LIKELY TO DEVELOP BY LATE

EVENING AND OVERNIGHT HOURS.  INSTABILITY AND WIND SHEAR WILL
INCREASE AS THE STRONG STORM SYSTEM APPROACHES...WITH THESE
CONDITIONS SUPPORTING A RISK OF SEVERE WEATHER AREA-WIDE THROUGH
MUCH OF THE OVERNIGHT HOURS.  LARGE HAIL WILL BE A POTENTIAL
IMPACT FOR ANY OF THE STRONGER STORMS. PORTIONS OF
SOUTHEAST OKLAHOMA INTO WEST CENTRAL ARKANSAS WILL BE NEARER
THE HIGHER LOW LEVEL MOISTURE...AND THIS WILL ALLOW THUNDERSTORM
UPDRAFTS TO BE BASED NEARER THE SURFACE.  SHOULD STORMS IN THIS
REGION EXPERIENCE THESE MORE FAVORABLE CONDITIONS...THEN THE
POTENTIAL INCREASES FOR DAMAGING WINDS AND TORNADOES

THE CHANCES FOR ACCUMULATING SNOW HAVE INCREASED GIVEN THE EXPECTED
TRACK OF THE STORM SYSTEM...WITH A BAND OF SIGNIFICANT SNOW AMOUNTS
LIKELY.  ADDITIONALLY...STRONG NORTHWESTERLY WINDS WILL DEVELOP
AS THE STORM STRENGTHENS OVER THE CENTRAL PLAINS.  THIS WILL PRODUCE
AREAS OF BLOWING AND DRIFTING SNOW WHICH WILL FURTHER IMPACT
TRAVEL.  ALSO...DANGEROUS WINDS CHILLS WILL DEVELOP THURSDAY NIGHT
INTO FRIDAY AS THE COLDER AIR CONTINUES TO SPILL INTO THE REGION.
THE FORECAST SNOW AMOUNTS AND LOCATION WILL CONTINUE TO BE REFINED
IN LATER FORECASTS.  HOWEVER...SIGNIFICANT IMPACTS TO TRAVEL ARE
LIKELY THURSDAY INTO FRIDAY ACROSS PORTIONS OF OKLAHOMA AND POINTS
FURTHER NORTH INTO THE CENTRAL PLAINS.
DRY AND COLD WEATHER IS EXPECTED OVER THE WEEKEND...WITH THE NEXT
