Area Forecast Discussion...CORRECTED
National Weather Service Missoula MT
345 AM MDT Fri Aug 18 2017

.DISCUSSION...Warm and dry conditions will remain over the region
once again today. A dry cold front will push through western
Montana this afternoon and evening, which will bring gusty
westerly winds to much of the area. Because of the combination of
very dry conditions and gusty winds, today will become a critical
fire weather day for western Montana. As a result, the red flag
warnings remain in place for gusty winds and dry conditions. The higher
wind gusts still look to be between 6pm-9pm MDT, though conditions
will be breezy throughout the afternoon and potentially overnight
tonight into Saturday as well.

A dry airmass will settle in over the Northern Rockies behind the
front on Saturday, reinforcing dry conditions. Breezy afternoon
winds Saturday, and another shortwave of energy sliding through
the Northern Rockies on Sunday, will keep fire weather concerns
elevated through the weekend.

Another ridge of high pressure will build over the region by the
start of next week, allowing for the warm and dry conditions to
persist. One difference with next week is that we could be
looking at a resurgence of monsoonal moisture riding north under
the high pressure. Though only isolated showers are expected, so
much-needed widespread rain doesn`t look promising in the near
future.

Cloud cover should remain favorable for viewing the solar
eclipse.
