CWA LATE SATURDAY EVENING WITH INCREASING THUNDERSTORM CHANCES
STARTING AS EARLY AS LATE AFTERNOON IN NORTHEAST OKLAHOMA AND
SPREADING FROM NORTH TO SOUTH SATURDAY NIGHT. WITH THE WARMER
CONDITIONS, INCREASING INSTABILITY SATURDAY AFTERNOON WILL AID IN
SEVERE POTENTIALS DEVELOPING ACROSS NORTHEAST OKLAHOMA INTO THE
EVENING HOURS. LARGE HAIL AND LOCALLY DAMAGING WINDS WILL BE THE
MAIN THREATS. OVERNIGHT, INSTABILITY AND THUS SEVERE POTENTIALS
ARE PROGGED TO WEAKEN WITH THE GREATER THUNDERSTORM CHANCES ACROSS
SOUTHEAST OKLAHOMA AFTER MIDNIGHT. MAJORITY OF THIS PRECIP SHOULD
EXIT BY 12Z SUNDAY, THOUGH WILL HOLD ONTO A SLIGHT CHANCE NEAR THE
RED RIVER FOR ANY LINGERING SHOWERS/STORMS.
UPPER LEVEL RIDGE OF HIGH PRESSURE MOVES OVER THE SOUTHERN PLAINS
SUNDAY AND EXITS DURING THE DAY MONDAY BEFORE ANOTHER SHORTWAVE
MOVES OUT INTO THE PLAINS MONDAY NIGHT. SOUTHERLY LOW LEVEL FLOW
RETURNS MONDAY AS THE RIDGE SHIFTS OFF TO THE EAST, WHICH WILL
HELP TO WARM TEMPS INTO THE MID/UPPER 80S. THE RETURN MOISTURE
FLOW WILL ALSO HELP FUEL THE STORM CHANCES DEVELOPING WEST TO EAST
MONDAY NIGHT.
THE SHORTWAVE MOVES OVER THE CENTRAL PLAINS TUESDAY INTO TUESDAY
NIGHT. CONTINUED MOISTURE RETURN ALONG WITH BOTH SURFACE AND
ELEVATED INSTABILITY ACROSS THE REGION FOR THIS WAVE TO WORK WITH
WILL INCREASE STORM AND SEVERE POTENTIALS AGAIN FOR THE CWA. ALL
MODES OF SEVERE WEATHER BECOME POSSIBLE TUESDAY AFTERNOON INTO
TUESDAY NIGHT BEFORE A COLD FRONT DROPS INTO THE CWA FOR
WEDNESDAY. LATEST MODEL SOLUTIONS INDICATE THE SURFACE AND OR AN
ELEVATED PORTION OF THE FRONT HOLDS OVER/NEAR THE CWA WEDNESDAY
INTO WEDNESDAY NIGHT WHILE ANOTHER SHORTWAVE LIFTS NORTHEAST
ACROSS THE REGION. DEPENDING ON WHERE THE SURFACE BOUNDARY SETS
UP FOR WEDNESDAY WILL HELP DETERMINE SEVERE POTENTIALS. CONDITIONS
ARE NOT ANTICIPATED TO CHANGE MUCH INTO NEXT THURSDAY WITH THE
WAVE MOVING THROUGH FROM WEDNESDAY NIGHT AND THE POTENTIAL FOR
ANOTHER DISTURBANCE THURSDAY NIGHT. THUS, WILL KEEP THUNDERSTORM
CHANCES IN THE FORECAST WEDNESDAY THROUGH THURSDAY.
BESIDES THE SEVERE WEATHER THREAT NEXT WEEK, A HEAVY RAIN THREAT
ALSO EXISTS OVER THE REGION. SOUTHERLY LOW LEVEL MOISTURE RETURN
TUESDAY AND CONTINUING THROUGH THE WEEK WILL ALLOW FOR THE
MULTIPLE ROUNDS OF STORMS TO HAVE AMPLE AMOUNTS OF MOISTURE TO
FEED OFF OF. WIDESPREAD RAINFALL AMOUNTS OF UP TO SEVERAL INCHES
ARE FORECAST TUESDAY THROUGH THURSDAY, WHICH ON TOP OF RECENT
RAINS WILL QUICKLY INCREASE THE FLASH FLOOD AS WELL AS
RIVER/STREAM FLOOD CONCERNS. CONTINUE TO MONITOR LATEST CONDITIONS
AS PRECIP AMOUNTS AND LOCATIONS ARE UPDATED.
