Tonight through Friday night...

Tonight, an upper air disturbance will move southeastward over the Northern Rockies and produce scattered showers (20-90% chance, greatest over southern Big Horn County, MT) from vorticity advection and mid-level frontogenesis. Precipitation amounts will be light, less than 0.10 inches, for most areas. A few isolated locations could receive up to 0.20 inches. Light snow, less than one inch, is possible above 7000-8000 feet. It will also be breezy with wind gusts to 30 mph over far southeast MT tonight due to a pressure gradient there.

Thursday, we will be under northwesterly flow aloft with some modest instability to support isolated to scattered showers (20-40% chance). Low-level moisture looks lower for this period so precipitation amounts should be even lighter than those expected tonight. Snow showers will be limited to elevations above 7000-8500 feet and will produce less than one inch accumulation.
Breezy conditions will continue over far southeast MT with gusts to 30-35 mph.

Late Thursday afternoon into the evening, strong surface high pressure will move southeastward from Alberta to Montana. Before the core of the surface high gets to MT, a cold front will cross our area, causing a wind shift to northeasterlies that will bring in cooler air from the north. Isolated to scattered showers (20-40% chance) will develop mainly over south central MT and north central WY, though any precipitation will be very light (0.10 inches or less), and greatest in the mountains and adjacent foothills. Snow showers will be limited to elevations above 8000-9000 feet and will produce less than one inch accumulation.

Overnight Thursday night, winds will decrease, showers will dissipate, and skies could become mostly clear to partly cloudy as subsidence with the surface high pressure moves into the area.
The cloud cover late Thursday night is uncertain, and this is causing uncertainty in the low temperature forecast. A freeze is still possible in the Billings area, but is likely from Wheatland County to Musselshell County, and parts of Rosebud, Custer, Powder River, Big Horn, Sheridan (WY) Counties.

Friday into Friday night, upper air and surface ridging will give mostly clear skies and light winds.

Low temperatures will generally be in the 30s and 40s tonight, 20s and 30s Thursday night, and will range from the upper 20s near Baker to the lower 40s in the Beartooth/Absaroka and Crazy Foothills Friday night. RMS

Saturday through Wednesday...

Anomalously strong upper ridge will move over the region for Saturday through Monday. Monday still looks like the warmest day of the period with highs in the 70s to lower 80s. Also relative humidities have trended a little lower for Monday with values from 20-22% around KBIL looking like the lowest values. Monday does not look too breezy so fire concerns do not appear significant.
Clusters bring upper diffluence over the forecast area on Tuesday ahead of the next Pacific trough. Part of the trough moves over the region for Wednesday. Probabilities for this system were not very high for a wetting rain (0.10 in.), with the highest readings ranging from 30% in KLVM to 45% on the NE slopes of the Beartooths/Absarokas on Tue. night. Temps will fall with the onset of the system...with highs in the 60s on Wednesday. Arthur


Gusty W to NW winds in the 20s will decrease this evening. Expect LLWS at KMLS tonight. Otherwise, conditions will be VFR with MVFR possible in scattered to numerous showers tonight. Expect areas of mountain obscuration this afternoon and tonight with widespread obscurations over the NE Bighorns. Arthur
