291 FXUS66 KOTX 291755 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 1055 AM PDT Mon Jun 29 2026 .KEY MESSAGES... - Wetting rains into Monday for eastern WA and north ID including over 1.00" of rain in the mountains of ID. - Thunderstorms in northeast WA and north ID Monday afternoon and evening. - Warmer and drier for the end of the week && .SYNOPSIS... On Monday afternoon and evening, scattered showers and thunderstorms are expected over north ID and northeast WA. Cooler than normal conditions continue through the week with isolated mountain shower activity. By the weekend, a ridge will build bringing temperatures back up to normal in time for the holiday weekend. && .DISCUSSION... Monday through Tuesday: Bands of rain are moving through the Inland Northwest and will continue to do so through late Monday night, with the exception of the Northern Mountains and the Idaho Panhandle. For much of the area, these rains will be beneficial, with ~0.10 inches expected from Colville down to Spokane and eastward. Highest rainfall totals will be seen in the Idaho Panhandle due to its closer proximity to the upper level low. Rainfall totals in Shoshone County could reach 1.0 to 1.25 inches. In addition to the rainfall, in the afternoon and evening there is a chance (20 to 30 percent) for thunderstorms due to elevated instability in the Northern Mountains, northern ID Panhandle. There is a lesser chance in the Spokane/Coeur d'Alene area (10 to 20 percent). High-res models favor a couple hundred Joules of CAPE, high PWATs of over 1 inch, and slow storm motion at around 10 kts. When combining high PWATs with low storm motions, main concerns with thunderstorms will be isolated heavy rainfall alongside small hail and lightning. This will be monitored closely for any flooding issues, alongside any storms that pass over burn scars. Maximum temperatures across the Inland Northwest remain lower than normal by 5-10 degrees and will remain in the low 70s to low 80s. Minimum temperatures also remain below normal in the low 40s to low 50s. Wednesday through Friday: The middle to the end of the work week will be relatively dry apart from showers in the mountains due to orographic lift as lower heights remain over the area. Temperatures will continue to be cooler than normal, though a weak ridge moving closer to the coast near the end of the week will allow for some warming. Holiday Weekend: Clusters near the holiday weekend begin showing signals for said ridge strengthening and moving through the forecast area, supporting a warmup. Saturday, July 4th, shows temperatures in the 80s alongside breezy winds and low relative humidity. On Sunday, temperatures are projected to get into the high 80s and low 90s, which will bring a return of isolated Moderate HeatRisk to the area. /AS && .AVIATION... 18Z TAFs: MVFR stratus is slowly dissipating for the GEG/KSFF/COE areas. For the afternoon attention turns to scattered showers and thunderstorms developing over the northern mountains, with a 20 percent chance of thunderstorms impacting KGEG/KSFF/KCOE between 21z-04z. Thunderstorms today will be capable of producing brief downpours, small hail, and wind gusts up to 35 MPH. A combination of rain saturating the boundary layer and low level upslope will continue to promote IFR/MVFR stratus this morning at KPUW, KCOE. For KGEG/KSFF forecast leans towards VFR conditions persisting. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence VFR conditions persist through the TAF period at KEAT/KMWH. Moderate confidence of VFR conditions at KGEG/KSFF this morning. Thunderstorms producing gusty outflow winds and brief heavy rain may result in TAF amendments this afternoon and evening at KGEG/KSFF/KCOE, but with 20% chances did not mention in the TAF for now. /JDC ----------------------- Confidence descriptors: Low - Less than a 30 percent chance Moderate - 30 to 70 percent chance High - Greater than a 70 percent chance For additional probabilistic information for NWS Spokane airports, please refer to the Aviation Dashboard on our webpage: https:/www.weather.gov/otx/avndashboard && .Preliminary Point Temps/PoPs...
