MAINLY FAR EASTERN PORTIONS OF THE FORECAST AREA, AS HIGH
PRESSURE ALOFT BEGINS BUILDING INTO THE REGION FROM THE WEST. AT
THE SURFACE, A FRONTAL BOUNDARY WILL STALL THROUGH OR JUST SOUTH
OF THE REGION BY THE END OF THE DAY. THIS, COMBINED WITH DAYTIME
HEATING IN THE MIDDLE 90S, WILL AGAIN RESULT IN ISOLATED TO
SCATTERED SHOWERS AND STORMS DEVELOPING ACROSS AREAS MAINLY ALONG

WITH GUSTY WINDS POSSIBLE. AS SUCH THERE IS A MARGINAL RISK FOR
ISOLATED SEVERE STORMS CAPABLE OF PRODUCING DAMAGING WIND GUSTS
OVER SOME CENTRAL AND EASTERN PORTIONS OF THE CWA THIS AFTERNOON.
WITH HIGH PRESSURE ALOFT AND AT THE SURFACE BECOMING MORE PREVALENT
ACROSS THE REGION THROUGH THE REMAINDER OF THE FORECAST PERIOD, RAIN
CHANCES ESSENTIALLY DWINDLE TO NIL. HOWEVER IN THE AFOREMENTIONED
FRONTAL BOUNDARY'S WAKE, DRIER AIR AND LESS HOT CONDITIONS WILL
EXIST ACROSS THE FORECAST AREA FOR THE REMAINDER OF THE WEEK AND
INTO THE WEEKEND. AS HIGHS WEDNESDAY RANGE FROM THE LOW TO MIDDLE
90S, COME LATE WEEK AND INTO THE WEEKEND THEY'LL RANGE FROM THE
