Area forecast discussion, May 16, 9:45 PM CDT, 2 hours 23 minutes before
EASTERN OKLAHOMA/NORTHWEST ARKANSAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE TULSA OK 945 PM CDT TUE MAY 16 2000 PESKY SHOWERS AND THUNDERSTORMS THAT HAVE BEEN WIDELY SCATTERED ACROSS THE FORECAST AREA HAVE NOT GONE AWAY WITH SUNSET AS FORECAST. THE 00Z ANALYSES SHOWED A SUBTLE DISTURBANCE AND WARM ADVECTION OCCURRING AT 500MB...WHICH IS LIKELY WHERE MOST OF THE CONVECTIVE ACTIVITY ACROSS THE REGION IS ORIGINATING. THE CLUSTER OF STORMS OVER NORTH CENTRAL OKLAHOMA IS HEADING FOR AREAS JUST NORTH AND WEST OF TULSA...BUT IT HAS BEEN WEAKENING. THE ZONES HAVE ALREADY BEEN UPDATED TO INTRODUCE A CHANCE OF SHOWERS AND STORMS ACROSS MUCH OF NORTHEAST OKLAHOMA WITH THE BEST CHANCE NORTHWEST OF THE TULSA AREA. ALSO LEFT IN A SLIGHT CHANCE OVER THE REMAINDER OF THE AREA...EXCEPT NEAR THE RED RIVER. THE NORMAN SOUNDING IS WELL CAPPED TO LOW BASED CONVECTION...BUT KSGF AND KLZK ARE NOT AS CAPPED. SO MAY SEE ACTIVITY PULSE UP LATE AS IT GETS EAST OF THE AREA. OTHERWISE...WINDS HAVE CONTINUED TO GUST IN EASTERN OKLAHOMA...SO MENTIONED IT IN WESTERN ZONES. TEMPERATURES LOOKED IN LINE WITH CURRENT DEWPOINTS WHICH SHOULD BE CLOSE. MOSTLY CLOUDY SKIES LOOK GOOD...EXCEPT NEAR THE RED RIVER WHERE PARTLY CLOUDY PREFERRED. FCSTID = 19 .TUL... AR...NONE. OK...NONE.
