DRY WEATHER AND ABOVE AVERAGE TEMPERATURES WILL CONTINUE INTO EARLY
NEXT WEEK. RIDGING ALOFT AND HIGH PRESSURE AT THE SFC ARE EXPECTED
TO DOMINATE THROUGH SUNDAY. HIGH TEMPERATURES WILL REMAIN 15 TO 25
DEGREES ABOVE CLIMO NORMS.
THE PATTERN CHANGES ABRUPTLY ON TUESDAY, THOUGH MODELS ARE STILL NOT
IN FULL AGREEMENT ON EXACT TIMING, POSITION OR STRENGTH OF THE SFC
LOW AND UPPER TROUGH THAT MOVES INTO THE PLAINS. FOR THE MOMENT,
SOUTH DAKOTA MAY REMAIN MOSTLY DRY UNTIL TUESDAY NIGHT WHEN A TROWAL
SETS UP, BUT CAA IS MINIMAL. SO, THIS ALL MAY DEPEND ON TIMING AS
DAYTIME HIGHS APPEAR TO STAY ABOVE FREEZING ON WEDNESDAY WHILE
OVERNIGHT LOWS DROP BELOW FREEZING EACH NIGHT. SOME MIX OF RAIN/SNOW
IS EXPECTED BUT DETAILS REMAIN SKETCHY THIS FAR OUT.
THE ONLY OTHER THING OF NOTE IN THE SHORT TERM IS THE POTENTIAL FOR
SOME PATCHY FOG DEVELOPMENT LATE TONIGHT INTO FRIDAY MORNING FROM
THE JAMES VALLEY EAST.
