WINTRY MIX OF SLEET...SNOW AND FREEZING RAIN HAS SNOW TRANSITIONED OVER TO ALL SNOW EXPCEPT FOR AREAS OF SOUTHEATS NEBRASKA INTO SOUTHWEST IOWA WHERE CHANGE EXPECTED SHORTLY AFTER MIDNIGHT. RADAR AND MTRS SHOW AREA OF HEAVIER SNOW ACROSS PTNS OF WRN AND NRN KS INTO SW AND S CNTRL NEB WORKING NEWD AS DYNAMICS FROM SNOPTIC SCALE UPPER TROF CONTINUE TO INCREASE.

RATHER STEEP MID LEVEL LAPSE RATES AND SOME INDICATION OF COUPLED UPPER JET STRUCTURE WITH SYSTEM ALSO INTERESTING. FOR NOW WILL FCST AMOUNTS IN WARNING AREA OF AROUND 5 TO 8 INCHES. HOWEVER WOULD NOT BE SURPRISED TO SEE LOCAL HIGHER AMOUNTS AS UPPER SYSTEM MOVES ACROSS NRN KS PUSING DEFORMATION ZONE OVER SE NEB AND SW IA.. WINDS WILL ALSO CONTINUE TO GENERATE SNOW AND BLOWING SNOW. LESSOR AMOUNTS IN NERN NEB STILL LOOK OK. .OMA...WINTER STORM WARNING...TONIGHT...EAST CENTRAL AND SOUTHEAST NEBRASKA AND SOUTHWEST IOWA.

THIS AIRMASS IS COLD ENOUGH FOR 15:1 SOUTH AND PERHAPS 20:1 NORTH. SOME HINT OF POTENTIAL FOR BRIEF CONVECTION OR CSI IN SOUTHEAST COUNTIES OVERNIGHT. SO IF ALL SNOW...MAX AMOUNT COULD BE APPROACHING 10-12 INCHES IN EXTREME SOUTHEAST CORNER. HOWEVER MODEL SOUNDINGS KEEP AN ELEVATED WARM LAYER INTO THE EVENING HOURS IN THE SOUTHEAST...SO SOME PRECIPITATION WILL FALL AS SLEET BEFORE DYNAMICAL COOLING AND A DEEPENING COLD AIRMASS CHANGE IT TO ALL SNOW. THIS WILL LIMIT SNOW ACCUMULATION ESPECIALLY SOUTHEAST. INITIAL THOUGHTS ON SNOW ACCUMULATIONS RANGE FROM 6-8 INCHES FAR SOUTHEAST TO 2-4 ORD/LXN... ENDING BY NOON FRIDAY. NEXT CONCERN IS THE WINDS...WHICH ARE A BIT CHALLENGING GIVEN THE LACK OF A DEFINED SURFACE LOW IN THIS COLD AIR. H85 CIRCULATION SHOULD BE SOMEWHERE OVER NRN MISSOURI FRIDAY...SO STRONG WINDS SEEM LIKELY OVER MOST OF THE CWA AT LEAST IN THE MORNING. HIGHEST GUSTS SHOULD BE NEAR 40 MPH...PLENTY FOR BLOWING AND DRIFTING SNOW PROBLEMS WITH THE FLUFFY SNOW/COLD AIR.
