1158 AM CDT FRI APR 17 2009

FORECAST IS BASED ON IGNITION TIME OF 1200 CDT ON APRIL 17.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.UPDATED DISCUSSION...

RH LEVELS ARE NOT COMING DOWN AS QUICK AS PREVIOUSLY THOUGHT DUE
TO THE THICK CLOUD COVER OVERHEAD. A CLEARING IS DEVELOPING BEHIND
THE PASSING CLOUDS ACROSS THE SOUTHERN RED RIVER VALLEY. SEEMS
LIKELY THAT THE BURN SITE WILL SEE SOME GOOD SUN STARTING AROUND
1 OR 130 PM. AT LEAST A COUPLE HOURS OF SUN WILL ALLOW THE RH
LEVELS TO DECENTLY FALL. HOWEVER...ADJUSTED THE MINIMUM RH FOR
THE DAY HIGHER THAN THE EARLIER FORECAST. WINDS ARE ALREADY OUT OF
THE NORTHWEST AND SHOULD BECOME NORTH BY THIS EVENING.

PREVIOUS DISCUSSION...

EXPECT A WARM DAY WITH PARTLY TO MOSTLY CLOUDY SKIES. WEST SURFACE
WINDS NEAR 10 MPH WILL PROGRESSIVELY BECOME NORTH BY THIS EVENING.
RH VALUES LOOK LESS DRY TODAY...DOWN TO 40 PERCENT. GOOD SMOKE
DISPERSION THROUGH MID EVENING. DECENT RH RECOVERY TONIGHT.

HIGH PRESSURE KEEPS THE AREA DRY SATURDAY. RH VALUES LOOK SIMILAR
TOMORROW...THERE SHOULD BE LESS CLOUDS...AND STRONGER NORTH WINDS
ARE LIKELY.
