.DISCUSSION...
QUIET UPPER LEVEL NORTHWESTERLY FLOW EXPECTED TO KEEP THE AREA DRY
FOR TODAY...WITH PLENTY OF SUNSHINE. WINDS WILL BE THE PRIMARY
CONCERN FOR TODAY...WITH THE SPEEDS MORE THAN DIRECTION. THE WIND
DIRECTION THROUGH THE DAY IS EXPECTED TO REMAIN NORTHWEST TO
NORTHERLY AS THE PLAINS SIT BETWEEN LOW PRESSURE NEAR THE GREAT
LAKES REGION AND HIGH PRESSURE OVER THE ROCKIES. SPEEDS ARE THE
MAIN CONCERN...AND THE COMBINATION OF A TIGHTENED SURFACE PRESSURE
GRADIENT...SUNNY SKIES AND GOOD MIXING POTENTIAL WILL BRING
INCREASING WINDS THROUGH THE DAY. CURRENTLY...SPEEDS ARE IN THE
10 TO 15 MPH RANGE...BUT AS WE APPROACH LATE MORNING/MIDDAY AND
THEN THROUGH THIS AFTERNOON...SUSTAINED SPEEDS CLOSER TO 20 MPH
ARE EXPECTED...AS ARE GUSTS OF 25 TO 30 MPH. CONDITIONS WILL BRING

THE LOWER/MID 60S...WITH MINIMUM RELATIVE HUMIDITY VALUES BY MID
AFTERNOON DROPPING INTO THE MID 20 PERCENT RANGE.

LOOKING TOWARD TUESDAY...GOOD NEWS IS THAT THE FORECAST REMAINS
DRY WITH MOSTLY CLEAR/PARTLY CLOUDY SKIES. BAD NEWS IS THAT WIND
SPEEDS ARE AGAIN A CONCERN. TONIGHT WINDS WILL TAKE ON A MORE
