NATIONAL WEATHER SERVICE DULUTH MN
1051 AM CDT FRI MAY 21 2010

FORECAST IS BASED ON IGNITION TIME OF 1100 CDT ON MAY 21.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...AREA OF LOW PRESSURE WELL TO THE SOUTH WILL CONTINUE
TO STREAM HIGH CLOUDS AND SOME LOW LEVEL MOISTURE INTO THE REGION
THROUGH THE REST OF THE MORNING. BY THE EARLY AFTERNOON...SKIES
SHOULD BEGIN TO SCATTER OUT...WHICH SHOULD ALLOW THE BOUNDARY
LAYER TO HEAT UP AND PRODUCE SOME CONVECTIVE CUMULUS CLOUDS. WITH
THE INCREASED LOW LEVEL MOISTURE...THERE IS A CHANCE OF AN
ISOLATED SHOWER THIS AFTERNOON. THE BEST CHANCE SHOULD BE AFTER 2
PM CDT. WITH THE ATMOSPHERE BECOMING UNSTABLE...THERE IS ALSO A
SLIGHT CHANCE OF AN ISOLATED THUNDERSTORM. HOWEVER...CONFIDENCE IN
A THUNDERSTORM NEAR THE PRESCRIBED BURN TODAY IS LOW. EVEN WITH
THE ADDED MOISTURE...HUMIDITY VALUES THIS AFTERNOON WILL STILL BE
ABLE TO DROP INTO THE UPPER 20S AND LOWER 30S. WINDS WILL BE
GENERALLY FROM THE SOUTHEAST WITH POSSIBLY STRONGER GUSTS THIS
AFTERNOON 10 TO 15 MPH. SKIES WILL BECOME PARTLY CLOUDY TONIGHT
WITH SOME PATCHY FOG EARLY TOMORROW MORNING. IF CONDITIONS BECOME
UNREPRESENTATIVE FEEL FREE TO GIVE ME A CALL.
