.DISCUSSION...
A COLD FRONT WILL MOVE THROUGH WEST CENTRAL MINNESOTA TONIGHT...
TURNING THE WINDS FROM SW TO NW. AT THIS TIME...THE BEST ESTIMATE
OF FRONTAL PASSAGE AND THE WINDS SWITCHING TO THE NW WOULD BE
FROM 11 PM TO 1 AM TONIGHT. THE LATEST MODEL INDICATIONS SHOW THAT
THE ATMOSPHERE STABILIZES VERY QUICKLY THIS EVENING...WHICH WOULD
ABOUT ELIMINATE THE POTENTIAL FOR ANY THUNDERSTORM ACTIVITY FOR
YOUR AREA WITH THE FRONTAL PASSAGE.

LOOK FOR HIGH TEMPERATURES TODAY AROUND 75...WITH MINIMUM RELATIVE
HUMIDITIES AROUND 25 PERCENT AND SUSTAINED WIND SPEEDS AROUND 15
MPH...WHICH IS APPROACHING CRITICAL FIRE WEATHER CONDITIONS.
