WYOMING AND MOVING EAST AND SOUTHEAST INTO FORECAST AREA AS AN
MCS. STRONG 100 KT 250 MB AXIS SEEN ACROSS THIS AREA AS WELL WHICH
SHOULD HELP ENHANCE CONVECTION. POPS FOR TONIGHT HAVE BEEN

BE SEVERE. WENT CLOSE TO GUIDANCE TEMPERATURES WITH LOW TEMPERATURES
IN THE MID 50S TO LOWER 60S.

SUBSIDENCE BEHIND THE MCS AND CONVECTION OF LAST NIGHT. THEN
