DISCUSSION

MOSTLY CLEAR SKIES ENCOMPASS THE NATURAL STATE EARLY THIS
MORNING, ALTHOUGH A COMPLEX OF SHOWERS AND STORMS ACROSS PORTIONS
OF SOUTH-CENTRAL TO EASTERN TEXAS WILL BRING PARTLY TO MOSTLY
CLOUDY SKIES AND MAYBE EVEN SOME LOW-END SHOWER POTENTIAL ALONG
THE SOUTHERN FRINGES OF THE STATE LATER TODAY. THIS ACTIVITY IS
DUE TO A WEAK SHORTWAVE UPSTREAM OF THE MAIN RIDGE IN PLACE ACROSS
CENTRAL CONUS. THE MOST FAVORABLE DYNAMICS WILL REMAIN SOUTH OF
THE STATE, BUT SOME SHOWERY ACTIVITY PEAKING OVERNIGHT TONIGHT AS
THE SHORTWAVE TRAVERSES EASTWARD ACROSS THE STATE CANNOT BE RULED
OUT. OTHERWISE, SEASONABLY WARM BUT COMFORTABLE TEMPERATURES WILL
CONTINUE THROUGH THE MIDDLE OF THE WEEK WITH HIGHS IN THE 70S AND
80S AND LOWS IN THE 40S AND 50S.
LONGWAVE TROUGHING ACROSS THE PACIFIC NORTHWEST WILL BEGIN TO PUSH
THE RIDGE CURRENTLY IN PLACE EAST OF THE REGION GOING INTO THE
LATTER PORTIONS OF THE WEEK. THIS WILL AID IN USHERING IN
PROLONGED ENHANCED SOUTHERLY FLOW AND ASSOCIATED MOISTURE LEVELS
AHEAD OF BETTER DYNAMICAL SUPPORT AS THE SUBTROPICAL AND POLAR
JETS PHASE ACROSS THE PLAINS LATE WEEK AND INTO THE WEEKEND.
ENSEMBLE CLUSTER ANALYSIS SHOWS THIS TROUGHING FEATURE LINGERING
ACROSS NORTHERN CONUS THROUGH AT LEAST THIS WEEKEND BEFORE SLOWLY
EJECTING EASTWARD EARLY NEXT WEEK. THIS SCENARIO WOULD RESULT IN
A PROLONGED PERIOD OF SOUTHERLY FLOW AS A NUMBER OF SHORTWAVES
ROTATING AROUND THIS LONGWAVE WOULD BRING MULTIPLE CHANCES FOR
RAINFALL LATE THIS WEEK AND EXTENDING INTO NEXT WEEK. SEVERE
WEATHER POTENTIAL INCREASES STARTING AS EARLY AS THURSDAY, WITH
50TH PERCENTILE DEW POINTS REACH INTO THE LOWER TO MID-60S BY
FRIDAY. DEPENDING ON PATTERN EVOLUTION, THE WARM/MOIST SECTOR
CURRENTLY ADVERTISED COULD REMAIN ACROSS THE STATE INTO EARLY
NEXT WEEK, WHICH WOULD BE A SCENARIO THAT COULD LEAD TO MULTIPLE
DAYS OF SEVERE WEATHER. THUS, WILL HAVE TO MONITOR TRENDS AND
HONE IN ON THE DETAILS AS WE DRAW NEARER ON RAINFALL AND SEVERE
WEATHER POTENTIAL. NONETHELESS, A PROLONGED PERIOD OF UNSETTLED
WEATHER PATTERN LATE THIS WEEK AND EXTENDING INTO NEXT WEEK IS OF
THE HIGHEST CERTAINTY. TEMPERATURES PROJECT TO REMAIN ABOVE NORMAL
LEVELS THROUGH THE EXTENDED PERIOD.
