I'm pretty blown away (pun intended) by the model forecasts for tonight and tomorrow (Sunday) morning.
The 0600 UTC NAM is generating strong easterly flow across the northern Wasatch Front with 700-mb (near crest-level) winds reaching 50 knots in places. There is also a strong pressure gradient from Evanston to Ogden. Coming overnight and in the early morning, these are ingredients for a strong downslope wind event.
The National Weather Service has issued a high-wind watch for the Cache Valley and northern Wasatch Front for sustained winds between 30 and 40 mph with gusts in excess of 60 and localized gusts in excess of 75 mph in some areas, especially Davis and Weber Counties.
Take the time today to secure loose outdoor items if you are in areas affected by these downslope winds and monitor forecasts at http://www.wrh.noaa.gov/slc/.
