EASTERN OKLAHOMA/NORTHWEST ARKANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OKLAHOMA
249 PM CDT TUE AUG 5 2003

SURFACE TROF EXTENDS SOUTHWEST FROM AN AREA OF LOW PRESSURE CENTERED
JUST SOUTH OF TULSA THIS AFTERNOON. COULD SEES SOME WIDELY SCATTERED
SHOWERS AND THUNDERSTORMS ALONG THIS BOUNDARY LATER THIS AFTERNOON
AND EVENING AS THE DIURNAL HEATING HELPS ERODE THE CAP THAT IS
CURRENTLY IN PLACE. IF ANY THUNDERSTORMS DO DEVELOP THEY WILL HAVE
THE POTENTIAL TO BECOME SEVERE WITH A SURFACE BASED CAPE OF 3500
J/KG AND A LI OF -5. THE MAIN SEVERE THREAT WILL BE STRONG
THUNDERSTORM WINDS AS DRY AIR WORKS IN AT THE MID LEVELS. WILL GO 20
POPS FOR THE MAJORITY OF THE AREA THIS EVENING. I WILL GO WITH
CHANCE POPS ACROSS PORTIONS OF NORTHWEST ARKANSAS AS THUNDERSTORMS
ARE EXPECTED TO DEVELOP LATE THIS AFTERNOON/EVENING ACROSS WESTERN
MO/EASTERN KS AND MOVE TO THE SOUTHEAST.

IT LOOKS LIKE HOT AND DRY CONDITIONS ARE ON TAP FOR THE REST OF THE
WEEK AS THE UPPER LEVEL RIDGE CURRENTLY CENTERED OVER THE
SOUTHWESTERN UNITED STATES NUDGES TO THE EAST. WILL LEAVE THE
EXTENDED PORTION OF THE FORECAST DRY FOR NOW BUT THE GFS IS HINTING
AT A POSSIBLE MCS MOVING INTO NORTHERN SECTIONS OF THE FORECAST AREA
SATURDAY NIGHT.
