400 AM CDT TUE SEP 19 1995

STRONG POLAR COLDFRONT STILL ON ITS WAY TO OK ATTM.  EXPECT FRONT TO
CROSS THE FA AND BE IN SE OK BY LATE THIS AFTERNOON...SLIGHTLY
AHEAD OF THE FASTER AVN SOLUTION...DUE TO THE STRENGTH OF THE SURFACE
RIDGE.  THIS SHOULD SET THINGS UP FOR CONTINUED THUNDER IN SE OK THROUGH
THIS EVENING.  ELSEWHERE...SHOWERS LIKELY BEHIND COLDFRONT AS UPPER
WAVES TRACK ACROSS THE AREA AND MOISTURE REMAINS AMPLE.  FEEL THAT
NGM IS TOO ENTHUSIASTIC WITH MOISTURE/POPS FOR WEDNESDAY AND WEDNESDAY
NIGHT...SO WILL LEAVE FCST DRY FOR NOW.  MOS IS WAY TOO WARM ON TEMPS...
THROUGHOUT FCST SO WILL STICK CLOSE TO PREVIOUS FORECAST...WHICH IS
CLOSER TO THE AVN NUMBERS. CLEARING SKIES AND ABATING WINDS WEDNESDAY
NIGHT SHOULD ALLOW FOR GOOD RADIATIONAL COOLING AND CRISP
TEMPERATURES...PARTICULARLY NORTHWEST OKLAHOMA.
