SPOT FORECAST FOR 6 MILE RX...USFS
NATIONAL WEATHER SERVICE DULUTH MN
939 AM CDT FRI MAY 21 2010

FORECAST IS BASED ON IGNITION TIME OF 1000 CDT ON MAY 21.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...AN AREA OF LOW PRESSURE LOCATED IN EASTERN IOWA IS
PULLING UP SOME LOW LEVEL MOISTURE FROM THE SOUTH ALONG WITH
SCATTERED HIGH CLOUDS AND SOME VERY LIGHT PRECIPITATION INTO
SOUTHEASTERN MINNESOTA AND WEST CENTRAL WISCONSIN. AREAS NEAR THE
PRESCRIBED BURN HAVE REMAINED DRY WITH ONLY A FEW HIGH LEVEL
CLOUDS OVERHEAD. THESE CONDITIONS SHOULD PERSIST THROUGH THE REST
OF THE MORNING. LOW LEVEL MOISTURE WILL CONTINUE TO INCREASE
SLIGHTLY THROUGH THE AFTERNOON WITH DEWPOINTS INTO THE LOWER
50S...AND TEMPERATURES INTO THE LOWER 70S. MINIMUM HUMIDITY VALUES
THIS AFTERNOON SHOULD BE SIGNIFICANTLY HIGHER THAN
YESTERDAY...ONLY DOWN INTO THE LOWER 30S. THE ATMOSPHERE SHOULD
BECOME SLIGHTLY UNSTABLE THIS AFTERNOON...AS THE HIGH LEVEL CLOUDS
SCATTER OUT AND ALLOW THE BOUNDARY LAYER TO HEAT UP. CURRENTLY
THINK THERE IS A BETTER CHANCE FOR JUST CONVECTIVE SHOWERS AND NOT
THUNDERSTORMS AFTER 2 PM CDT. IF CONDITIONS BECOME
UNREPRESENTATIVE FEEL FREE TO GIVE ME A CALL.
