Sunday 12:30PM
High Wind Watch has been replaced by a High Wind Warning that goes into effect at 11:00AM Monday Morning. Now is the time to secure all movable items in the yard throughout Mono and Inyo Countys, and especially the Crowley Lake, Aspen Springs Ranch and down wind. Strength of upper jet at 250MB is nearly 140 Knots and with WNW jet Down Sloping expected. Winds may accelerate to hurricane force+ in gusts across highway 395 Monday Afternoon. Tree Damage, Roof damage possible in many areas. A High Wind Warning is hoisted for the Ownes Valley for the sametime period Monday, with highway 395 cross winds up to 80MPH in areas below canyons.
Precipitation: With the upper jet having more of a WNW trajectory, major accumulations are not expected. The QPF forcasts have been trimmed back at bit today for the Monday and Tuesday AM storm with 7 to 9 inches possible over the crest, and half of that at the Village. However, this upcoming week will offer yet another windy storm with more snowfall. Being that antecedent conditions are not as warm, the winds are not excpected to be quite as strong as Mondays system and freezing levels are not as low. Additionally, this system will have better over-water trajectory and the odds of getting a foot or better seems more reasonble with the Thursday-Friday system. The unsettled weather pattern may last into the weekend now and although Easter Sunday at this time looks fair, I would not bank on it.
A big point to be made is that skiing and boarding conditions will greatly improve with the two incoming storms this week!!! But get it while its cold!! Easter Weekend seems like a good time to cut up some freshies!!

3:30pm 4/9/22 update
The Storm for Monday and Tuesday still looks good, but with a twist. Evidently the models have been trending wetter then they showed a few days ago…..Also Colder. A High Wind watch still looks good for Mono County Monday afternoon and night. However, the Owens Valley has been added to that Watch, beginning 11:00AM Monday. Strong downsloping winds are expected along the eastern slopes of the sierra Monday Afternoon creating Hazardous driving conditions. Strong Cross winds along Highway 395 Monday PM, will potentially be strong enough to flip high profile tractor trailers with gusts to 80 MPH possible in wind prown areas..
QPF: CA River forecast center is showing over an inch of water near Yosemite Monday and Tuesday and so up to a foot of snow is possible over the crest from this first storm. By Tuesday 5:00AM, the freezing level is expected to lower to 1500 feet. Another possibly as wet or wetter system is getting progged for the second half of the new week…..Beginning as early as Wednesday Night. Another Foot? Still looking at a fair Easter Sunday at this time.

While Yesterday felt like an early June day, near record warmth is occuring in many areas of our state and Nevada. An anomaliously cold trough will pay the state a visit Monday into Tuesday, creating strong temperatures gredients and potentially, strong downsloping winds for the eastern slopes of the high country, The NWS has hoisted a high wind watch for Mono County along the highway 395 corridor beginning at 1:00PM, Monday. This time of the year, a NW upper jet with its front RT exit region, can really play havoc on our region. The storm which will provide light snowfall Monday into Tuesday is expected to lower the freezing level to 2,000 over Yosemite, at 5:00AM Tuesday Morning. There is another weaker trof expected the following Thursday for a bit of cooling a slight chance of snowshowers, and 1st look at the Easter Holiday weekend looks a bit breezy Saturday with sunny skys and a bit warmer than normal temps…..IE., A beautiful weekend.
