DISCUSSION...FIRE WEATHER CONDITIONS WILL IMPROVE A LITTLE TODAY WITH

TO INHIBIT ANY LAKE BREEZE OFF SAGINAW BAY.

FRIDAY CONTINUES TO LOOK MORE HAZARDOUS...AND CONFIDENCE REMAINS
HIGH FOR RED FLAG CONDITIONS TO DEVELOP. LOW PRESSURE LIFTING TO OUR

DRIER AIRMASS. A COMBINATION OF MIN RH VALUES IN THE
MID 20S...TEMPERATURES NEAR 80...SUSTAINED WINDS NEAR 20 MPH...AND
