AREA FORECAST DISCUSSION

NWS WICHITA KS

AFDICT 1117 AM CST FRI FEB 1 2002

ONLY MINOR CONCERN FOR THE SHORT TERM WILL BE THE TEMPERATURES.

LATEST SURFACE ANALYSIS SHOWS HIGH PRESSURE ACROSS THE ROCKIES 
PLAYING A LARGE INFLUENCE ACROSS THE AREA. TEMPERATURES STILL 
STRUGGLING TO GET OUT OF THE TEENS IN THE SNOW PACKED AREAS WITH 
MAINLY 20S ELSEWHERE. LATEST ACARS SOUNDING AT ICT SHOWS IF WE MIX 
OUT FROM 900 MB WE SHOULD REACH THE UPPER 30S AT ICT. HOWEVER...WITH 
STILL PLENTY OF SNOW AND ICE COVER IN PLACE AND TEMPERATURE TRENDS 
BEING A LITTLE SLOWER THAN GUIDANCE THEN WE HAVE LOWERED 
TEMPERATURES A CATEGORY IN ALL LOCATIONS. 

.ICT...NONE.
