WITH AIR TEMPERATURES DIPPING TO THE SINGLE DIGITS BELOW ZERO BY

OF I-70.
A SYSTEM WILL PASS TO OUR N DURING THE DAY TUESDAY, PROMPTING AN
INCREASE IN SFC FLOW OUT OF THE SW AND SOME GUSTS ON THE ORDER OF 20-

AND WEDNESDAY MORNING, ALLOWING FOR FAVORABLE RADIATIONAL COOLING
CONDITIONS, WITH LOWS AGAIN GOING SUBZERO FOR MOST OF THE ILN FA AND

DAY WEDNESDAY THROUGH SATURDAY.
