SPOT FORECAST FOR SETHRE...USFWS
NATIONAL WEATHER SERVICE GRAND FORKS ND
743 AM CDT TUE SEP 27 2011

FORECAST IS BASED ON IGNITION TIME OF 1300 CDT ON SEPTEMBER 27.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...
A RIDGE OF HIGH PRESSURE LAY ACROSS THE FORECAST AREA MUCH OF THE
DAY RESULTING IN LIGHT WINDS. THE WINDS ALOFT ARE FORECAST TO BE
FROM THE NORTH TO NORTHWEST 10 TO 15 MPH THIS MORNING BUT
DECREASE TO LESS THAN 10 MPH BY IGNITION TIME. SO AS MIXING
INCREASES...WINDS ARE EXPECTED TO TAKE ON A RELATIVELY CONSISTENT
NORTHWEST DIRECTION...BUT YOU SHOULD STILL EXPECT A FAIR AMOUNT
OF DIRECTIONAL VARIABILITY. GUSTS TO 10 MPH ARE POSSIBLE AS
MIXING IS MAXIMIZED.

WITH THE LIGHT WINDS MIXING WILL BE POOR THIS MORNING THEN BECOME
FAIR THIS AFTERNOON.

A RELATIVELY SIMILAR DAY TOMORROW EXCEPT WINDS SHOULD TURN TO THE
SOUTHWEST AND PERHAPS INCREASE SLIGHTLY AS THE PRESSURE GRADIENT
INCREASES.
