FIRST ROUND OF CONVECTION MOVED ACRS MUCH OF THE FA DURG THE MRNG
AND AFTN HRS. LOW LVL RH HAD CONTD TO RETURN IN EARNEST ACRS THE
REGION THIS AFTN THANKS TO INCRSG SLY WINDS. SFC DEWPOINT READINGS

MEANWHILE...FOCUS THRU THIS EVENING WL BE WITH ONGOING CONVECTION
ACRS CNTRL AR AND THE LINE OF STORMS TO THE W ALONG THE CDFNT. THE
ACTIVITY ALONG THE FNT WL EVENTUALLY AFFECT MUCH OF THE FA INTO THIS
EVENING. KEPT A MENTION OF SVR STORMS IN THE FCST AS DAMAGING WINDS

LONG TERM...MONDAY THROUGH THURSDAY

THE LONG TERM FORECAST WILL BE INFLUENCED PRIMARILY BY AN UPPER
CLOSED LOW WOBBLING AROUND THE REGION. AT THE START OF THE LONG
TERM...THIS UPPER CLOSED LOW WILL BE CENTERED TO THE NW OF THE STATE
OVER NE AND SD...WITH AR REMAINING IN INTENSE SW FLOW ALOFT. MUCH OF
STATE WILL CONTINUE TO BE IN DEEP SRLY FLOW...WITH AMPLE MOISTURE IN
PLACE. AS A RESULT...ANY UPPER DISTURBANCES ROTATING AROUND THE BASE
OF THE UPPER TROUGH WILL LIKELY TRIGGER ADDITIONAL SHRA/TSRA ON MON
INTO MON NIGHT. WHERE THE BEST POPS WILL BE DURING THIS PERIOD ARE
UNCERTAIN AT THIS TIME...AND WILL DEPEND GREATLY ON WHERE THE COLD
FRONT WILL BE LOCATED. FOR NOW...WILL HAVE BEST POPS ACROSS THE ERN
HALF OF THE CWA ON MON...THEN DECREASING MON NIGHT INTO TUE. THE
FRONT WILL EVENTUALLY SHIFT EAST AND EVEN NE OF THE STATE INTO THE
MIDDLE OF NEXT WEEK...WITH COOLER CONDITIONS EXPECTED FOR MUCH OF
NEXT WEEK. HOWEVER...DO NOT REMOVE POPS COMPLETELY AS THE UPPER LOW
WOBBLES TO THE NORTH...AND ADDITIONAL DISTURBANCES DROP SOUTH OVER
THE STATE. THIS COULD BRING ADDITIONAL SHRA TO THE STATE THROUGH
MUCH OF THE END OF THE FORECAST.
