CONTINUE TO DECREASE THROUGH THE DAY AS A HIGH PRESSURE CENTER
MOVES IN THIS AFTERNOON AND EVENING. OTHERWISE, CLEAR SKIES
EXPECTED TODAY WITH THE ONLY OTHER ITEM OF NOTE BEING A STRONG
TEMPERATURE GRADIENT ACROSS THE FORECAST AREA EXPECTED TODAY.
HIGHS OVER NORTHEASTERN SOUTH DAKOTA AND WESTERN MINNESOTA WILL BE

A COLD FRONT IS MAKING ITS WAY THROUGH THE REGION LATE TONIGHT. BY
EARLY SATURDAY MORNING, ALL THAT IS EXPECTED TO BE LEFT ARE SOME
GUSTY NORTHWEST WINDS. WINDS WILL BE STRONGEST ALONG THE COTEAU WITH
GUSTS TO 40 MPH IN THE MORNING SUBSIDING IN THE AFTERNOON. SURFACE
HIGH PRESSURE BUILDS IN FROM THE NORTHWEST THIS AFTERNOON AND
EVENING BRINGING LIGHTER WINDS AND DRY CONDITIONS. THE DRY WEATHER
LOOKS LIKE IT WILL HANG AROUND AT LEAST THROUGH MID WEEK AS PASSING
SYSTEMS KEEP ANY PRECIP TO THE NORTH OR EAST.
A BUILDING UPPER RIDGE SUNDAY INTO MONDAY WILL PUSH TEMPS ABOUT 15
TO 20 DEGREES ABOVE NORMAL WITH HIGHS IN THE UPPER 30S TO UPPER 50S
ON MONDAY. EVEN WARMER TEMPERATURES ARE POSSIBLE WEDNESDAY OR
THURSDAY AS UPPER RIDGING PERSISTS AND SOUTHERLY FLOW AHEAD OF SFC
LOW PRESSURE HELPS AID MIXING.
MAIN CONCERN THROUGH MID WEEK WILL BE GRASSLAND FIRE DANGER AS FUELS
ARE DRY WHERE THERE IS NO SNOW PACK.
