SHORT TERM
Today through Monday...A positively tilted upper level ridge stretching from the Pacific Northwest through northern Saskatchewan has placed the region in a dry, northerly flow regime this afternoon. As of 2 PM PDT, temperatures are running 5 to 10 degrees warmer than this time yesterday with current temperatures in the 60s. Temperatures will continue to warm for the next couple hours with widespread highs for the Columbia Basin on track to warm into the upper 60s and lower 70s.
The upper level ridge will shift to the southeast overnight as a cold front moves through the region Saturday morning. While a band of light precipitation will accompany the cold front passage and showers develop behind the front over the Blues, winds will be the primary hazard. Westerly winds look to increase through the Kittitas Valley and the eastern Gorge) by mid Saturday morning as the surface pressure gradient tightens behind the cold front.
Winds will remain breezy through the afternoon with gust 30 to 45 mph through the gaps. Breeziness will also be felt in the neighboring valleys and the Columbia Basin with gusts 25 to 40 mph in the afternoon.
Weather will remain unsettled as a broad upper level trough digs into the northwest on Sunday. A shortwave embedded within the main flow will bring precipitation primarily to the mountains. Most lowland locations will miss out on the rain potential with the best chances (20 to 25 percent) for 0.01 inches across the foothills of the northern Blues. Breezy to locally gusty winds (gusts 30-45mph for the Cascade gaps, 25-40 mph for the Columbia Basin) will continue Sunday afternoon surface pressure gradients remain tightened across the forecast area. Temperatures will cool into the 50s and 60s for Sunday and Monday.
LONG TERM
Tuesday through Saturday...Quiet weather is anticipated for midweek with dry, split flow over the northwest.
Confidence in the pattern wanes by Friday as global ensembles diverge on the details as the next weather system approaches the western US. For Tuesday through Thursday, temperatures will gradually warm under this pattern. Tuesday morning looks to be the coldest morning of the period with lows in the low to mid 30s for the Yakima and Kittitas Valleys. /OTX
AVIATION
18Z TAFs... VFR conditions will continue through the forecast period. Mid to high level clouds will begin to move in from the west around 00Z ahead of an approaching cold front. Cold front passage will bring a 15 to 25 percent chance of light rain, but confidence is too low at this moment to include in TAFs. West to northwest winds will increase through the Columbia River Gorge and the Cascade Valleys behind the cold front passage after 12Z with sustained speeds 10-20 knots and gusts up to 30 knots.
