Fire Weather Planning Forecast for Northeast Montana
National Weather Service Glasgow MT
328 AM MDT Sun Jul 23 2017

...RED FLAG WARNING REMAINS IN EFFECT UNTIL 9 PM MDT THIS EVENING
FOR LOW RELATIVE HUMIDITY AND HIGH TEMPERATURES FOR FIRE WEATHER
ZONES 122, 134, 135, 136, AND 137...

...FIRE WEATHER WATCH IN EFFECT FROM MONDAY MORNING THROUGH
MONDAY EVENING FOR LOW RELATIVE HUMIDITY AND GUSTY WIND FOR
FIRE WEATHER ZONES 120, 122, 134, 135, 136, AND 137...


.DISCUSSION...Steady south winds are expected to develop by late
this morning and persist into the afternoon ahead of an
approaching cold front. Expect low relative humidity amid very hot
afternoon temperatures today as well. Isolated dry thunderstorms
may produce lightning strikes along and ahead of the front this
evening thorugh tonight. The passage is expected overnight with
gusty northwest winds developing on Monday. Despite lower high
temperatures on Monday, low relative humidity readings are still
expected. As a result of these considerations, critical fire
weather conditions will likely occur through at least the early
part of the week. An upper ridge building across the area into
the middle part of the week may only prolong the warm and dry
weather conditions.
