.DISCUSSION...
PRIMARY FORECAST CONCERN IS LINGERING CHANCE FOR SHOWERS AND
THUNDERSTORMS THIS EVENING...THEN AGAIN MONDAY THROUGH TUESDAY NIGHT.

AT EARLY AFTERNOON A QUASI-STATIONARY FRONT WAS HUNG UP EAST-WEST
ACROSS THE SOUTHERN THIRD OF THE CWA. THIS COMBINED WITH A RIPPLE OF
ENERGY ALOFT WAS PRODUCING A BAND OF THUNDERSTORMS ACROSS THE
SOUTHERN TWO THIRDS OF THE AREA. THIS EVENING MODELS IN DECENT
AGREEMENT BRINGING ANOTHER SHORT WAVE/VORT MAX CURRENTLY OVER
NORTHWEST MISSOURI SOUTHEASTWARD ACROSS ALL BUT THE NORTHEAST
SECTIONS OF THE CWA. SINCE THE AFOREMENTIONED FRONTAL BOUNDARY WILL
BE MOVING SLOWLY ACROSS THE SOUTHERN SECTIONS OF THE CWA DURING THE
SAME TIME FRAME...WILL LINGER CHC POPS ACROSS ALL BUT THE NORTHEAST
SECTIONS THIS EVENING.

TONIGHT...RAIN CHANCES WILL COME TO AN END AS SURFACE HIGH PRESSURE
CENTERED OVER SOUTHERN ONTARIO CONTINUES TO BUILD SLOWLY SOUTHWARD.
AS MOISTURE DECREASES THROUGH THE ATMOSPHERIC COLUMN...CLOUDS SHOULD
ALSO BECOME FEWER AND FARTHER BETWEEN. OVER THE WEEKEND...DRY
WEATHER IS EXPECTED...ALONG WITH SLIGHTLY COOLER AND LESS HUMID
CONDITIONS...AS THE CANADIAN HIGH BUILDS SOUTHEAST INTO THE OHIO
VALLEY.

BY EARLY NEXT WEEK...ANOTHER FRONTAL BOUNDARY WILL INFLUENCE THE
REGION WITH A CHANCE OF SHOWERS AND THUNDERSTORMS MONDAY THROUGH
TUESDAY NIGHT. MAINLY DRY CONDITIONS ARE FORECAST FOR THE REST OF
THE WEEK AS THE REGION FALLS UNDER THE INFLUENCE OF AN UPPER LEVEL
RIDGE.
