Area Forecast Discussion

National Weather Service Glasgow MT

323 AM MDT Fri May 9 2025



.DISCUSSION...



KEY MESSAGES:



- Temperatures will continue to warm into the weekend with highs

  above 90 expected on Saturday.



- Marginal Fire Weather concerns may arise with slightly lower

  humidity and slightly stronger winds than currently expected on

  Saturday.



- Unsettled weather pattern develops next week with cooling

  temperatures and chances for rain.



WEATHER PATTERN OVERVIEW:



Upper ridge will be building into the northern plains over the

next few days with hot and dry conditions expected. Temperatures

are expected to top out above 90s degrees across much of the 

region on Saturday with a corresponding relative humidity in the

teens. Fire weather concerns for Saturday may increase if 

forecast winds become stronger and/or forecast humidity drops 

more. 



Saturday night the high pressure ridge gives way to a new 

encroaching low pressure system from the west, which will allow 

for increasing chances for off-and-on showers and thunderstorms 

each day next week, with overall average confidence becoming 

greater with time. Concurrent model runs have shown than next week

could result in a wet and active weather pattern for our region 

with multiple days of off and on rain accumulations. 



FORECAST CONFIDENCE & DEVIATIONS:



Confidence is above average for hot temperatures this weekend. 

Confidence is average to better than average for repeating showers

and thunderstorm chances next week.
