206 PM CDT SUN AUG 14 2005

.DISCUSSION...
TONIGHT THROUGH SUNDAY
A QUASI-STATIONARY FRONT WILL LIKELY CONTINUE TO TRIGGER THE
DEVELOPMENT OF SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS OVER
PARTS OF MY NORTHERN COUNTY WARNING AREA TONIGHT. THE REST OF MY
AREA WILL LIKELY SEE A DECREASE IN ACTIVITY LATER TONIGHT.
GUIDANCE MODELS ARE NOT IN AGREEMENT ON THE MOVEMENT OF THE
FRONTAL BOUNDARY BUT THE OVERALL MEAN RELATIVE HUMIDITY IS
IMPRESSIVE. A FEW AREAS ACROSS THE NORTH COULD SEE SOME HEAVY
RAINFALL TONIGHT. SOME OF THESE STRONGER STORMS COULD SPREAD INTO
THE CENTRAL SECTIONS TOMORROW IF THE FRONT MOVES SOUTHWARD.
A RELATIVELY DRY DAY CAN BE EXPECTED NEXT SUNDAY.(38)
