SPOT FORECAST FOR KETTLEDRUMMER PRAIRIE...NATURE CONSERVANCY
NATIONAL WEATHER SERVICE GRAND FORKS ND
914 AM CDT SUN MAY 3 2009

FORECAST IS BASED ON IGNITION TIME OF 1530 CDT ON MAY 03.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...HIGH PRESSURE WILL LEAD TO SUNNY SKIES THROUGH THE
DAY. GIVEN GOOD MIXING OF WINDS FROM ALOFT...EXPECT A STEADY
NORTHWEST WIND 5 TO 10 MPH THROUGH THE DAY. THE POTENTIAL EXISTS
FOR A BRIEF GUST UP TO 15 MPH (GIVEN WIND SPEEDS AVAILABLE TO MIX
FROM ABOVE TO THE SURFACE). MINIMUM HUMIDITIES WILL BE AROUND 25
PERCENT (POTENTIALLY INTO THE LOW 20S). THIS TAKES INTO ACCOUNT
DRY AIR MIXING TO THE SURFACE FROM ALOFT DURING THE AFTERNOON
HOURS. SMOKE DISPERSAL WILL BE EXCELLENT BY IGNITION TIME...AND
REMAIN EXCELLENT THROUGH THE AFTERNOON HOURS. WINDS WILL BECOME
LIGHT AND VARIABLE DURING THE EVENING HOURS...MUCH LIKE THE
PREVIOUS DAYS.
