Weather Synopsis
2:50 PM update relating to Mt Hood weather.
The cooldown associated with a broad upper trough dropping southward has been dramatic. Freezing levels at Quilliyute dropped from 9,300 to 3,300 from Sunday to Monday morning. Cooling continues as the trough settles into the region. The upper-level flow features WNW winds as the trough slides just to our north over central and southern British Columbia. As of Monday afternoon, these winds are enhanced by a 10 mb temperature gradient across the Cascades. These gradients and associated low-level winds likely peak Monday night, before gradually starting to subside on Tuesday. Before these gradients do subside, expect some continued strong to extreme winds for the west side of Mt Hood with much lighter winds further east. For Washington State, epect moderate ridgeline winds for areas near and east of the Cascade Crest, including the mountain gaps. This flow pattern has produced several weak convergence bands in the central and northern Puget Sound regions but most precipitation has been light. Rain/snow shower activity peaks Monday night for the central and northern Cascades. With continued cooling and snow levels dropping down to 2500 ft or lower, expect several inches of snow from Snoqualmie Pass to Mt Baker, with perhaps a few areas slightly west of the Cascade Crest getting a bit more.
Snow showers become more isolated on Tuesday as the upper trough shifts toward northern Idaho. Cold temperatures aloft could drive an isolated convective shower or two with a slight uptick in light to moderate ridgeline winds, clouds, and shower activity in the afternoon.
The Pacific Northwest lingers near the western edge of the exiting trough Tuesday night and Wednesday. Expect a cool start to Wednesday with freezing levels rebounding to around 5000 ft or slightly higher. More sunshine is in store with lighter winds shifting NWerly.
NWAC will issue daily Mountain Weather Forecasts through April 28th, with the exception of April 18th, when we will be closed for an end-of-season forecaster meeting.
