NATIONAL WEATHER SERVICE DULUTH MN
107 PM CDT TUE MAY 3 2011

FORECAST IS BASED ON IGNITION TIME OF 1330 CDT ON MAY 03.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...HAVE UPDATED THE FIRE WEATHER SPOT FOR HIGHER
WINDS. NORTHEAST WINDS SHOULD CONTINUE THROUGHOUT THE AFTERNOON
BEFORE SHIFTING TO THE SOUTH OVERNIGHT. THE WINDS WILL BE STRONGEST
BETWEEN 1 PM AND 4 PM...AND THEN DIMINISH DURING THE EVENING.
VERY LOW HUMIDITY WILL BE THE MAIN FEATURE FOR THE AFTERNOON AS
WE EXPERIENCE FULL SUNSHINE. WE WILL BE MIXING DOWN AIR FROM
AROUND 8 TO 10 THOUSAND FEET THIS AFTERNOON. THE RESULT WILL BE
RELATIVE HUMIDITIES IN THE 20 PERCENT RANGE. SOME SPOTS MAY
ACTUALLY DIP A BIT BELOW 20 PERCENT FOR A TIME THIS AFTERNOON. I
WILL BE HERE ALL DAY...SO GIVE ME A CALL IF YOU HAVE ANY ISSUES OR
IF THE FORECAST IS UNREPRESENTATIVE FOR ANY REASON. I WILL BE
WATCHING HUMIDITY VALUES VERY CLOSELY.
