FIRE WEATHER PLANNING FORECAST FOR NORTH-CENTRAL MONTANA
NATIONAL WEATHER SERVICE GREAT FALLS MT
257 PM MDT SUN JUL 6 2025
DISCUSSION
A SIGNIFICANT WARM UP IS EXPECTED ACROSS THE AREA THROUGH MIDWEEK
AS UPPER LEVEL RIDGING BUILDS ACROSS THE NORTHWESTERN US, WITH
DRY AIR SENDING RH VALUES INTO THE LOW TEENS DURING THE
AFTERNOONS. THIS UPPER LEVEL RIDGE WILL BREAK DOWN AROUND MIDWEEK
AHEAD OF A SIGNIFICANT COOLDOWN, WHICH COULD HELP GENERATE SOME
GUSTY WINDS LATE WEDNESDAY ALONG WITH A LOW RISK OF SHOWERS AND
THUNDERSTORMS DEPENDING ON THE TIMING OF A COLD FRONT LATER THIS
WEEK. THE SECOND HALF OF THE WEEK WILL BE MARKEDLY COOLER, WITH
HIGHS IN THE 70S AND LOW 80S AS OPPOSED TO THE 90S TO NEAR 100°
TUESDAY AND WEDNESDAY.
