DISCUSSION
ISSUED AT 1240 AM CDT SUN APR 19 2026
AS OF ABOUT 1 AM CDT WE HAVE SOME SHOWERS MOVING ACROSS THE AREA BUT
THE PRECIPITATION IS NOT REACHING THE GROUND DUE TO THE VERY DRY AIR
IN PLACE. TEMPERATURES ARE IN THE 30S AND ARE EXPECTED TO FALL INT
THE MID TO HIGH 20S BY SUNRISE. WINDS ARE OUT OF THE WEST TO
NORTHWEST AT ABOUT 10 TO 15 MPH.
TODAY WILL BE ANOTHER DRY DAY WITH HIGH PRESSURE OVERHEAD AND HIGHS
WILL BE A BIT WARMER ACROSS CENTRAL SD, NOT SO MUCH ACROSS
NORTHEASTERN SD. MONDAY, OUR WINDS SHIFT AROUND TO BE OUT OF THE
WEST TO SOUTHWEST BRINGING IN SOME GOOD WAA AND TEMPERATURES WILL
RISE TO BE ABOUT 15 DEGREES WARMER THAN NORMAL. 15-25 DEGREES ABOVE
NORMAL TEMPS WILL LAST THROUGH THURSDAY. ALSO ON THURSDAY A LOW
MOVES INTO ND WITH A COLD FRONT EXTENDING DOWN AND SWEEPING ACROSS
THE FORECAST AREA DURING THE DAYLIGHT HOURS. THIS WILL BRING A
CHANCE FOR SOME RAIN STARTING WEDNESDAY EVENING, LASTING THROUGH THE
DAY THURSDAY WITH SOME POTENTIAL FOR STORM. IF THE FRONT MOVES
FASTER THAN CURRENTLY FORECAST, TEMPERATURES MAY NOT GET AS WARM AS
CURRENTLY EXPECTED. MUCH COOLER AIR MOVES IN BEHIND THE COLD FRONT
THURSDAY, BRINGING TEMPERATURES BACK DOWN TO AROUND NORMAL AND STAY
COOLER FOR NEXT WEEKEND.
WINDS ON MONDAY WILL ONCE AGAIN GUST TO 30-35 MPH, MAINLY ALONG AND
EAST OF THE MISSOURI RIVER AS AN AREA OF LOW PRESSURE MOVES TOWARDS
THE REGION. NO PRECIPITATION IS EXPECTED WITH THIS LOW AT THIS TIME,
BUT THE WINDS AND DRY AIR WILL INCREASE GRASSLAND FIRE DANGER.
HIGHEST WIND GUSTS DO NOT CURRENTLY OVERLAP WITH LOWEST RELATIVE
HUMIDITY VALUES, HOWEVER, ANY FIRES THAT DO START COULD STILL SPREAD
QUICKLY DUE TO DRY FUELS. GRASSLAND FIRE DANGER IS EXPECTED TO STAY
ELEVATED THROUGH AT LEAST WEDNESDAY.
