AREAS AFFECTED…Eastern NE & Western IA

CONCERNING…HEAVY SNOW….

INCH AN HOUR SNOWFALL RATES /GREATER IN THUNDERSNOW/ WILL GRADUALLY TAPER OFF LATER THIS MORNING. CESSATION OF HEAVIER RATES IS ALREADY ONGOING ACROSS CENTRAL NEB.  HEAVY SNOWFALL HAS DEVELOPED IN THE FAVORED LEFT EXIT REGION OF A MID-UPPER LEVEL JET…NOW QUICKLY PROGRESSING NORTHEASTWARD.

WITH THE LESSENING OF MORE SUPPORTIVE VERTICAL MOTION…RATES SHOULD GRADUALLY BEGIN TO TAPER OFF THIS MORNING. UNTIL THEN…WEAK MID-LEVEL INSTABILITY HAS SUPPORTED THE OCCASIONAL LIGHTNING STRIKE ACROSS SOUTHERN NEB. THIS AREA OF ENHANCED CONVECTIVE SNOWFALL POTENTIAL WILL SHIFT INTO SOUTHERN IA OVER THE NEXT FEW HOURS. BRIEF BURSTS OF HEAVIER SNOW REMAIN POSSIBLE IN THUNDERSNOW.
