Area forecast discussion, Jul 9, 3:11 PM CDT, 1 hour 37 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WICHITA KS 311 PM CDT FRI JUL 9 1999 MAIN FCST PROBLEM IS PRECIP CHCS OVERNIGHT. ALL MODELS SIMILAR THROUGH 48 HRS. COLD FRONT IS MOVING SLOWER THAN EXPECTED. HOWEVER EXPECT IT WILL SLIDE SOUTH ACROSS THE ENTIRE AREA THROUGH THE REST OF THE AFTERNOON AND EVENING HOURS. EXPECT IT TO MAKE IT ALL THE WAY THROUGH FCST AREA AFTER MIDNIGHT. CEN SECTIONS SHOULD SEE THE PRECIP THIS AFTERNOON AND EVENING. SOUTHERN SECTIONS WILL HAVE PRECIP LINGER INTO THE OVERNIGHT HOURS AS FRONT CONTINUES TO MOVE TO THE SOUTH. THINK THE FRONT WILL BE SOUTH OF THE OKLAHOMA BORDER BY 12Z SAT AND REMAIN THERE THROUGH EXTENDED. WILL THEREFORE CONTINUE DRY FCST FROM SAT ON INTO THE EXTENDED. TEMPS ARE ANOTHER PROBLEM. CONDITIONS ARE COOLER AND MUCH DRIER BEHIND THE FRONT. SO HOW COOL SHOULD I GO THROUGH SAT NIGHT. MOS GUIDANCE SEEMS REASONABLE FOR LOWS BUT CONSIDERING THE TIME OF YEAR AND AMOUNT OF SUNSHINE EXPECTED...WILL GO A LITTLE WARMER THAN GUIDANCE ON HIGH TEMPS. EXTENDED FCST WILL REMAIN UNCHANGED. WEDNESDAY WILL SEE HIGHS AGAIN IN THE 90 TO 95 RANGE WITH LOWS AROUND 70.
