High Wind in Hill County, Montana

ASOS station KHVR Havre Airport measured a 70 mph gust. Other sensors in this zone that measured a 58+ mph gust include EW1937 Goldstone and FW1664 Hingham.

Large scale upper level troughing with two separate embedded upper level lows progressed across the region late June. The colder core, which actually ended up being the southern of the two, moved across Southwest Montana and resulted in snow levels falling to below 6,000ft at times as heaviest precipitation moved over the area. Heavy snow developed near and above pass level in northwest Beaverhead County, resulting in nearly 2 feet of snow near the peaks close to the ID border.

Meanwhile further north under the second upper low, a strong surface low ended up developing near the Hi-Line, which resulted in strong winds in a few zones before the surface low filled/weakened.

Strong upper level support further north resulted in widespread heavy rains, with additional upslope forcing along the Rocky Mountain Front, which resulted in some flooding in Glacier NP June 29.
