SPOT FORECAST FOR ROUND ISLAND RX...USFS
NATIONAL WEATHER SERVICE DULUTH MN
300 PM CDT TUE MAY 18 2010

FORECAST IS BASED ON IGNITION TIME OF 1500 CDT ON MAY 18.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...QUIET WEATHER IS IN STORE FOR TODAY THROUGH WEDNESDAY.
MOSTLY CLEAR SKIES AND FAIRLY LIGHT WINDS WILL BE THE RULE. THE
RELATIVE HUMIDITY HAS BEEN A BIT TRICKY TODAY...AS THERE HAVE BEEN
POCKETS OF FAIRLY LOW HUMIDITY MIXING DOWN FROM ALOFT. SOME LOCATIONS
HAVE SEEN HUMIDITY VALUES FALL INTO THE TEENS. I THINK THE ROUND ISLAND
SITE SHOULD SEE HUMIDITY VALUES REMAIN IN THE 20 PERCENT RANGE. JUST
GIVE ME A CALL IF CONDITIONS BECOME UNREPRESENTATIVE.
