The episode as NWS OTX wrote it up.
A back building snow band moved continue to move over Wenatchee and East Wenatchee in Douglas county. Several reports in the area from the public and trained spotters recorded snow amounts of 7 to 16 inches. The heavy snow caused school closures and power outages. It was a recording snowfall for the area for single day of April and the month of April.

Area Forecast Discussion National Weather Service Spokane WA 1003 PM PDT Wed Apr 13 2022 .SYNOPSIS... Unseasonably cool, showery, and breezy weather will continue through the end of the week. Anticipate widespread below freezing overnight temperatures through Saturday. Temperatures will begin warming to near seasonal values early next week with continued chances for widespread precipitation on Saturday and again by the beginning of next week. && .DISCUSSION... .Rest of this evening...The main focus for the evening and overnight forecast will revolve around the west-east deformation band of light snow currently stretching from Moscow to Ritzville and Ellensburg. Satellite trends suggest this feature is going to shear apart as it drifts slowly north and west. This suggest the coverage of the precipitation will likely wane on the eastern end, while it might strengthen as the low-level easterly flow brings orographic ascent to locations closer to the Cascades. While most of the Hi-Res Cam models are showing this feature, it seems the the ARW/FV3 are doing the best and this is reflected in the HREF ensembles. Both of these models show decent enhancement as the western edge of the band pushes into the southern Chelan and Douglas Counties. Snowfall totals in these areas will be spotty, but much like the last couple days could be locally heavy due to very unstable mid-level lapse rates combined with an increasingly moist air mass. It looks like Mission Ridge will be the location most likely to get appreciable snow. It is entirely possible that 4-8" of snow could fall there overnight with nearby locations seeing an inch or less. Since the snowfall will be so spotty there is no reason to issue winter weather advisories at this time. fx && .AVIATION... 06Z TAFs: Surface low is spinning off of the coast near Astoria, OR. A narrow band of snow will continue to move westward towards the Cascades overnight. Light snow is expected under this band with deteriorating ceilings that will primarily impact the KEAT- KMWH TAF sites. Snow will result in marginal VFR conditions after 06Z with low confidence for IFR conditions where more persistent snow develops under this band. Northeast winds will remain breezy through the Purcell Trench and out over the basin. The northeast pressure gradient will weaken overnight into Thursday. && .PRELIMINARY POINT TEMPS/POPS...
