...NO TSTM AREAS FORECAST...

...SYNOPSIS...
AN UPPER-LEVEL SHORTWAVE TROUGH WILL MOVE FROM THE NRN ROCKIES INTO
THE NRN PLAINS ON SUNDAY. AS THIS TAKES PLACE...ASSOCIATED SURFACE
COLD FRONT WILL MOVE ACROSS THE DAKOTAS...WITH SWWD TRAILING FRONTAL
SEGMENT EXTENDING INTO THE SRN HIGH PLAINS. UPPER RIDGING WILL OCCUR
OVER THE ERN CONUS WITH SURFACE HIGH PRESSURE LOCATED BENEATH. SLY
FLOW WILL DEVELOP OVER THE SRN PLAINS AS THE HIGH SHIFTS EWD AND THE
SURFACE COLD FRONT ENTERS THE GREAT PLAINS. THE INCREASING SLYS WILL
INSTIGATE MODEST MOISTURE RETURN ACROSS THE TX GULF COAST...BUT
SUBSTANTIAL BUOYANCY IS NOT FORECAST TO DEVELOP...WHICH WILL
PRECLUDE THUNDERSTORM DEVELOPMENT. ELSEWHERE...A SRN STREAM
DISTURBANCE WILL MOVE E ACROSS NWRN MEXICO AND SRN AZ/NM DURING
SUNDAY MORNING. STEEP MIDLEVEL LAPSE RATES ACCOMPANYING THIS FEATURE
WILL AID IN GENERATING WEAK BUOYANCY OVER AZ/NM...BUT LIGHTNING
POTENTIAL IS CURRENTLY EXPECTED TO BE TOO LOW TO JUSTIFY A
CATEGORICAL THUNDER AREA.
