1026 AM EDT Fri Sep 2 2016 High pressure will maintain dry weather and seasonal temperatures through the weekend. Expect highs near/a couple degrees under the seasonal averages as cool advection under upper troughing offsets insolation. Dry conditions will prevail through midweek, but with much warmer temperature as the Southern CONUS ridge rebuilds in the wake of the tropical activity. VFR conditions are expected through the TAF period under building high pressure. No restrictions expected under high pressure.
1033 AM EDT Fri Sep 2 2016 High pressure will maintain dry weather and seasonal temperatures through the weekend. A quick correction/update was issued for near term sky cover as low convective thresholds under the upper trough should support more clouds than the previous forecast indicated. Expect highs near/a couple degrees under the seasonal averages as cool advection under upper troughing offsets insolation. Dry conditions will prevail through midweek, but with much warmer temperature as the Southern CONUS ridge rebuilds in the wake of the tropical activity.

High temperatures today will be a couple of degrees cooler than the previous day and about 5 to 7 degrees below normal for early September.
Cool unstable northwest flow aloft will maintain a good threat of showers today, and even some light snow to the highest peaks in the Cascades. Though threat of showers will be less this weekend, but we will still be on the cooler and cloudier side.
Further east, increasing flow aloft will result in a lee trough developing, with the deeper low level moisture being east of the state.
Even within the drier air aloft at least one subtle area of moistening is noted and could still promote isolated convection later this morning as some of the high-res NWP suggests. Regardless, moisture does continue to linger in the lower levels and with area observations showing near saturated conditions in light (generally upslope) flow additional development of stratus and pockets of fog are inevitable.
