BOZEMAN – Another chilly start this morning for SW Montana valleys. Below freezing in West Yellowstone and numerous near-record level lows elsewhere. So far, only one record low to report for Wednesday, July 15th, Livingston 37° this morning with a record low of 41° in 1944.
Temperatures started climbing this afternoon as a new high-pressure ridge is building in from the West. In fact, temperatures will jump up into the 80s and 90s Thursday and Friday.
The next weather maker is a mostly dry cold front arriving Friday afternoon or early evening. Ahead of the front temperatures will be very warm Friday. The front will also produce increasing surface winds by Friday afternoon. The combination of hot temperatures, low humidity, and increasing surface winds will likely lead to higher fire danger Friday afternoon.
Over the weekend a NW flow will redevelop and that should start to push temperatures back down into the 70s and 80s.
