Mostly cloudy skies and mild temperatures are in place on Friday with morning temperatures near freezing in the valley. The next storm will arrive Friday afternoon, with snow arriving between noon-2pm and continuing through the evening, before tapering off to light snow showers later Friday night through Saturday morning. Highs Friday afternoon will be in the mid 30s in the valley and the low 20s at 9,000 ft. with mountain winds out of the west/southwest at 10-20 mph with gusts to 25 mph.
Total snow amounts from Friday afternoon through Saturday morning will range from 3-6″ in the Tetons. Temperatures will be warm enough that some rain could mix in with snow in the valley (at least from the town of Jackson southward) on Friday afternoon before eventually changing to all snow, but overnight accumulations in the valley will generally be less than an inch. Lows Friday night will fall into the low/mid 20s in the valley.
Conditions will dry out Saturday afternoon with partial clearing in the cloud cover and highs reaching the low 30s in the valley and around 20 at 9,000 ft. The next storm I’ve mentioned in previous posts now appears to be arriving as two separate storm systems. The first storm will be the weaker of the two and will bring snow to the area from around midday Sunday through daybreak Monday morning.
Another 3-6″ of snow can be expected in the Tetons from Sunday through Sunday night. This storm will also be coming in warm with valley highs in the mid 30s, and rain could mix in with snow across the Jackson Hole Valley Sunday afternoon/early evening (more likely from the town of Jackson south) before changing over to all-snow Sunday night. Valley accumulations Sunday night should generally range from 0.5-2″. Temperatures at 9,000 ft. will rise into the mid 20s on Sunday afternoon before dropping Sunday night as a cold front arrives.
The second storm I mentioned now looks to arrive on Tuesday, and it should be a bit stronger than Sunday’s storm, and also not quite as warm.
