Jackson Hole Weather Friday January 17, 2020, Jan 17, 2020
A fast-moving storm system will bring a few quick shots of moderate to heavy snow on Friday morning and into early Friday afternoon before the snow tapers off by late afternoon. Total snow amounts through Friday afternoon will range from 3-7″ in the Tetons and 1-3″ in the Jackson Hole Valley. Mountain winds out of the southwest at 15-25 mph with gusts to 40 mph on Friday morning will shift to northwesterly with similar speeds on Friday afternoon. Valley winds will increase out of the southwest at 10-20 mph with gusts to 30 mph as the day progresses, resulting in areas of blowing snow on the roads.
High temperatures Friday will peak in the mid 20s in the valley, while in the mountains at 9,000 ft temperatures are starting out in the teens Friday morning, but will fall into the single digits Friday afternoon. Lows Friday night will fall into the single digits in the valley. Conditions will dry out on Saturday as high pressure starts to build in from the south, but lingering moisture will result in mostly cloudy to overcast skies. Highs Saturday will reach the mid 20s in the valley and upper single digits to low teens in the mountains at 9,000 ft. Mountain winds will be out of the west at 10-20 mph and valley winds will be out of the south at 5-15 mph.
Sunday will feature increasing sunshine and a warming trend across the higher elevations with mountain temperatures at 9,000 ft rising to around 20 degrees with relatively light winds. Valley temperatures will be highly dependent on how quickly a stronger inversion sets up (tough call on whether it happens Sunday or Monday). If the inversion holds off, then look for highs in the 30s in the valley, but if the inversion does develop early enough then highs would struggle to get out of the teens. Prepare for colder temperatures than what your weather app shows just in case the latter scenario plays out.
On Monday, skies will be mostly sunny with a strengthening inversion as highs reach the mid to upper 20s at 9,000 ft, while highs in the valley will be in the 20s following a morning low in the single digits. Looking farther out, the next chance of snow will arrive on Tuesday night or Wednesday.
