Fire Weather Planning Forecast for SCen and SErn Montana...UPDATED
National Weather Service Billings MT
905 PM MDT Sat Jul 22 2017

...Cold Front Early Monday Morning...
...Increasing Thunderstorm Activity This Week...

.DISCUSSION...
Updated the forecast to drop the Red Flag Warning just a bit
early this evening. Humidities were slow to recover, but were
inching up above 20 percent. Winds have decreased from the earlier
gusty periods of this afternoon. Recoveries tonight will be poor
again but the combination of slowly rising humidity and decreasing
winds, was enough to warrant canceling the Red Flag for the
remainder of the night. The rest of the forecast looks in good
shape and did not change. TWH

Weak upper level high pressure builds over the area on Sunday
bringing a warmup in temperatures and a decrease in wind. Surface
low pressure forming over Alberta will switch winds to southerly
directions and this downslope flow will support humidity minimums
in the teens. A disturbance will move into southwest Montana late
Sunday night which will push a cold front through the early early
Monday morning. Isolated thunderstorms are possible over the
mountains with the disturbance. The front moving through Monday
morning will bring a shift to stronger northwest winds but
humidity will be higher than previous day but minimums still
reaching 20 percent. Winds will be strongest over southeast
Montana but trending north. Isolated thunderstorms are possible
Monday evening but humidity will be increasing. The weather trend
for the week is for a series of disturbances bringing
thunderstorms but also cooler temperatures and higher humidity.
