THE SCATTERED SHOWERS AND THUNDERSTORMS AROUND THE REGION THIS
MORNING HAVE LARGELY DISSIPATED AND SHIFTED EAST WITH THE
DEPARTING MID LEVEL WAVE. SURFACE ANALYSIS SHOWS A WEAK FRONTAL
BOUNDARY HANGING OUT AROUND NORTHERN OKLAHOMA EXTENDING WESTWARD
INTO WEST CENTRAL OKLAHOMA AS A SURFACE LOW BECOMES CENTERED OVER
CENTRAL OKLAHOMA. ANOTHER WEAK MID LEVEL DISTURBANCE IS ALSO NOTED
ON WATER VAPOR IMAGERY MOVING ACROSS SOUTHERN KANSAS TOWARD THE
LOCAL REGION AROUND THE PERIPHERY OF THE STUBBORN UPPER RIDGE. HOT
CONDITIONS PERSIST, ESPECIALLY SOUTH OF THE WEAK BOUNDARY, WHERE
A HEAT ADVISORY CONTINUES THIS AFTERNOON. PERSISTENT SHOWERY
CONDITIONS AND CLOUD COVER HAVE KEPT TEMPERATURES IN CHECK FOR THE
MOST PART ACROSS THE NORTH AND EAST, SO WILL RUN WITH THE CURRENT
CONFIGURATION OF THE ADVISORY FOR NOW, WHILE MONITORING TRENDS.
LATER THIS AFTERNOON AND EVENING, LOW SHOWER AND THUNDERSTORM
CHANCES WILL DEVELOP AGAIN ACROSS EASTERN OKLAHOMA INTO WESTERN
ARKANSAS ALONG THE STALLED FRONTAL BOUNDARY AND IN RESPONSE TO
THE APPROACHING VORT MAX. SEVERE WEATHER IS NOT EXPECTED WITH THIS
ACTIVITY, BUT A FEW STRONGER STORMS COULD DEVELOP, WITH LOCALLY
DAMAGING WIND GUSTS THE MAIN THREAT. ANY STORMS THAT DO DEVELOP
WILL LIKELY WANE INTO THE OVERNIGHT HOURS AS THE INFLUENCE OF THE
MID LEVEL WAVE EXITS THE AREA, THOUGH A FEW SHOWERS COULD LINGER
ACROSS PORTIONS OF SOUTHEAST OKLAHOMA.
