.DISCUSSION...

SOUTHEASTERLY WINDS AT 5 TO 10 MPH SHOULD TURN MORE EASTERLY
AROUND IGNITION TIME...THEN SHIFT TO NORTHWESTERLY WITH A FEW
GUSTS TO 15 MPH BY 3 PM CDT AS A WEAK COLD FRONT PASSES THROUGH
NORTHWESTERN NORTH DAKOTA. THERE IS SOME UNCERTAINTY REGARDING THE
TIME OF WIND SHIFT...SINCE THE FRONT IS RATHER WEAK AND VERY SLOW
MOVING. FOR WEDNESDAY...WINDS SHOULD BE 5 TO 10 MPH OUT OF THE

MONTANA. THERE IS LITTLE CHANCE OF MEASURABLE PRECIPITATION TODAY
