AREAS OF LIGHT RAIN CONTINUE ACROSS EASTERN OKLAHOMA AND NORTHWEST
ARKANSAS THIS AFTERNOON IN ASSOCIATION WITH STRONG UPPER WAVE.
MAIN PRECIPITATION WILL BEGIN TO SHIFT EAST OF THE REGION BY EARLY
EVENING, HOWEVER WRAP AROUND LIGHT PRECIP WILL REMAIN POSSIBLE
ACROSS FAR NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS TONIGHT ON
BACKSIDE OF DEPARTING SYSTEM.
SECONDARY UPPER WAVE WILL QUICKLY MOVE OUT OF THE CENTRAL PLAINS ON
THURSDAY WITH LIMITED RAIN CHANCES INTO THURSDAY NIGHT WITH WEAK FRONTAL
BOUNDARY. OVERALL AMOUNTS WILL REMAIN LIGHT/ISOLATED GIVEN THE LIMITED
LOW LEVEL MOISTURE AVAILABLE. MOSTLY SUNNY CONDITIONS EXPECTED INTO
THE DAY FRIDAY AS SURFACE HIGH PRESSURE BUILDS OVER THE REGION WITH
HIGHS BACK INTO THE UPPER 60S TO LOWER 70S. A WARM/DRY WEEKEND ON TAP
AS UPPER RIDGE BUILDS OVER THE SOUTHERN PLAINS. TEMPERATURES WILL REMAIN
ABOVE NORMAL INTO THE EARLY PART OF NEXT WEEK AS SOUTHERLY WINDS
INCREASE.
BROAD UPPER TROUGH WILL BEGIN TO AMPLIFY OVER THE DESERT SOUTHWEST TUESDAY
INTO WEDNESDAY OF NEXT WEEK WITH INCREASING/DEEPER GULF MOISTURE SPREADING
INTO THE AREA FROM THE SOUTH. TIMING DIFFERENCES REMAIN IN THE OPERATIONAL
MODELS WITH INITIAL SHORT WAVE AHEAD OF MAIN UPPER TROUGH WHICH IS TO
BE EXPECTED THIS FAR INTO THE EXTENDED. STILL SOME POTENTIAL FOR SEVERE
WEATHER/HEAVY RAINFALL AROUND MID WEEK, HOWEVER THIS WILL BE DEPENDENT
ON EVENTUAL TIMING OF THE SMALLER SCALE FEATURES AND OVERALL
EVOLUTION OF MAIN UPPER TROUGH.
