242 FXUS66 KOTX 162344 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 344 PM PST Sun Nov 16 2025 .KEY MESSAGES... - Low impact and unsettled wet weather continues this week. && .SYNOPSIS... Next round of precipitation continues into Monday night. Mild temperatures will keep snow levels high with primarily light rain expected. Temperatures cooling closer to normal for the latter half of next week. A weak weather system on Thursday brings the potential for light precipitation and light snow in the mountains. Another wet weekend is on tap. && .DISCUSSION... Tonight through Tuesday: A deepening trough will stretch along the coast and position a Low off the coast of CA. Ahead of the trough, a strong southerly push is currently pushing a shower band south to north across Eastern WA and Idaho Panhandle. It will bring 0.1-0.2 of an inch of rain into the early overnight period. The trough and Low will promote a split flow over the Pacific Northwest and bring a small wave of moisture Monday into Tuesday. The zonal movement of the wave brings higher chance for precip to the Cascades and Idaho Panhandle mountains. While these areas are expected to 0.1-0.2 of an inch of precip, snow levels will start off around 7000ft tonight and gradually drop to around 4000ft by Tuesday afternoon. The timing of moisture and cold air will limit the potential winter weather as most of the precip will fall as rain before snow levels drop. Snow amounts for the passes are only up to inch Monday night into Tuesday. Basin precip will be only a few hundredths. Tonight lows will in the 40s followed by 30s for Monday night. Highs for Monday will be in the 50s and drop slightly into the upper 40s and low 50s. Recent rains and cooler air are expected to bring fog to portions of the Inland Northwest. Tuesday night through Sunday: With a ridge building into the area, drier air will move in behind the wave late Tuesday through Wednesday. Another trough begins to press into the region Wednesday night and last through Friday. Ensembles are in good agreement on the timing and location of the trough. However, the trough will again stretch along the coast causing the ensembles to diverge on the strength and moisture amounts as it passes. It will pull subtropical air leading rising snow levels to around 4500ft for the Cascades. Cascade passes could have periods winter weather travel as 2-4 inches are possible Friday into Saturday with a probability of 70% of at least 2 inches. Idaho Panhandle mountains including Lookout Pass will see 1-2 inches of snow with a probability of 50% of at least one inch. Rain across the lowlands will be a few hundredths of an inch. Ensembles are showing a brief break of precip on Saturday. It will be followed by the upper level jet supporting a moisture plume into the region and widespread showers to the region for Sunday. Highs will be in the 40s and low 50s. Lows will be in the upper 20s and 30s. /JDC && .AVIATION... 00Z TAFs: Widespread light rain showers are currently moving south to north through the Inland Northwest.
