...COLD FRONT WITH STRONG WINDS ARRIVES EARLY FRIDAY MORNING...

.DISCUSSION...
A dry cold front with strong winds will arrive Friday morning
between 8 AM and 10 AM MDT. Winds will increase out of the west
as the front passes. Fronts are always difficult to nail down in
the mountains, but that`s the best timing estimate I can come up
with. No precipitation is expected with the front at the burn
site, but light showers are forecast about 50 miles north. I have
boosted the winds forecast based on your feedback. Thanks for
submitting that.
