Weather Synopsis
Sunday will be the final day of an extended warm, dry stretch of weather. The upper-level weather pattern remains broadly similar, with westerly flow to our north and a closed low now moving inland over California. The associated cloud cover extending as far northward as southern Washington should dissipate around Mt Hood early this morning.
The main stories will be the warm temperatures on Sunday, increasing W winds, and a rapid cool-down heading into Monday. Most NWAC stations, including Camp Muir, were above freezing early Sunday morning. High temperatures on Sunday east of the Cascades should be warmer than Saturday. However, a strong surface high well offshore combined with a thermal low east of the Cascades will increase W winds to reasonably low elevations. This will initially begin to cool areas west of the Cascade Crest.
A broad trough eases southward over British Columbia Sunday night and Monday, rapidly cooling and increasing clouds. Most precipitation will hold off until the early morning hours on Monday. Expect periods of mostly very light rain and snow for the west slopes of the Cascades with 3000-4000 ft snow levels. Perhaps an inch or so of snow will accumulate in convergence bands. Meanwhile, moderate winds will buffet the east slopes of the Cascades and mountain gaps as pressure gradients increase to 10 MB across the Cascades by the afternoon.
7am Mountain Weather Forecasts will continue through Sunday, April 14th. Beginning Monday, April 15th, we will issue 230pm Mountain Weather Forecasts every day through Sunday, April 28th.
