Spot Forecast for Mill City Rx

.DISCUSSION...The upper level trough advancing toward the west coast
Thursday will generate an increasingly strong southwest flow aloft
across the fire site by Thursday evening. This strong and generally
dry southwest flow will remain strong through Friday morning, then
shift to the west behind a passing cold front early Friday afternoon.

Exposed areas of the burn could experience gusty southwest winds ahead
of the front late Thursday night until frontal passage early Friday
afternoon. The rather dry air mass ahead of the front and the limited
moisture trailing the front will keep precipitation on the low side
with only a minimal threat of wetting rains or accumulating snow.

The fairly warm temperatures ahead of the front Thursday through early
Friday afternoon will cool dramatically behind the front late Friday
afternoon/evening. West-northwest winds trialing the front will remain
gusty into early Friday evening. Temperatures will remain cool
Saturday, then warm substantially late in the weekend.
