DISCUSSION
ISSUED AT 440 AM CDT SUN JUN 29 2025
NEXT MID-LEVEL SHORTWAVE ENERGY IS MOVING EASTWARD ACROSS WY AND
GENERATING SHOWERS AND THUNDERSTORMS ACROSS WESTERN/CENTRAL SD.
EXPECT THIS ACTIVITY TO CONTINUE MOVING EASTWARD THROUGH THE
EARLY/MID MORNING HOURS, WITH WIND GUSTS AROUND 50 MPH AT TIMES IN
STRONGER CORES. A BIT UNCERTAIN HOW LONG THIS COMPLEX WILL HOLD AND
HOW MUCH, IF ANY, DECREASE IN AREAL COVERAGE WE'LL SEE AS IT MOVES
ACROSS THE STATE. WILL LIKELY NEED TO MAKE FURTHER POP ADJUSTMENTS
OVER THE NEXT FEW HOURS. AFTER THIS WAVE MOVES OUT LATER THIS
MORNING, YET ANOTHER PIECE OF ENERGY FURTHER UPSTREAM IN THE MID-
LEVEL FLOW LOOKS TO MOVE INTO THE AREA. CAMS ARE GENERATING
ADDITIONAL SHOWER/THUNDERSTORM ACTIVITY MOVING INTO CENTRAL SD LATE
AFTERNOON AND PUSHING EASTWARD ACROSS THE REGION INTO THE EVENING
HOURS. ALTHOUGH, THIS APPEARS TO BE MORE WIDELY SCATTERED IN NATURE,
AND AGAIN WE'LL BE LOOKING AT LOW SEVERE STORM POTENTIAL WITH A MORE
STABLE ATMOSPHERE IN PLACE TODAY.
ON MONDAY, MID-LEVEL FLOW BECOMES NORTHWESTERLY AS DRIER DEWPOINTS
IN THE 50S OVERSPREAD THE AREA. SURFACE HIGH PRESSURE BUILDS INTO
THE REGION WHICH WILL LEAD TO MOSTLY DRY CONDITIONS ACROSS THE AREA.
ALTHOUGH, WILL HAVE TO WATCH THE FAR EASTERN CWA FOR SHOWER
POTENTIAL CLOSER TO THE MAIN SHORTWAVE ENERGY FURTHER EAST.
ENVIRONMENT IS CHARACTERIZED BY STEEP LAPSE RATES OUT THAT WAY AS
WELL.
NEXT OPPORTUNITY FOR PRECIPITATION COMES TUESDAY NIGHT AS A LOW-
LEVEL JET GETS GOING AGAIN ACROSS THE NORTHERN PLAINS. SURFACE
BOUNDARY ALSO BEGINS PUSHING NORTHWARD INTO SOUTHERN SD.
