Area Forecast Discussion National Weather Service Spokane WA 342 AM PST Tue Feb 25 2020
The weather today will be seasonably cool with a mix of clouds and sun. A weak weather disturbance will bring clouds and light mountain snow to the Cascades and mountains of the Idaho Panhandle on Wednesday. Temperatures on Friday will likely be well above average with many areas climbing into the 50s. The arrival of a frontal system on Saturday will push temperatures down closer to average and bring increasing chances for rain and mountain snow.
DISCUSSION. Today through Friday . Good model agreement exists for this period featuring an upper level rideg over the region today providing benign but seasonably cool conditions with some passing clouds filtering the sun at times. Tonight this ridge flattens in response to a weak wave cresting over the top of it . with a fetch of moisture creating mountain snow showers particularly along the Cascade crest and the rising terrain of the Idaho Panhandle. Some of these overnight and Wednesday morning snow showers may back fill into the eastern Columbia Basin as flurries or late morning sprinkles. This moist zonal flow will continue Wednesday night and into Thursday . but with nothing to trigger any lift beyond orographic forcing on the whole the region will enjoy dry but variably cloudy conditions . and through this whole two day period any mountain snow accumulations will be light and probably not impactful for any travelers.
Friday will feature another upper level ridge in response to a stronger upstream trough approaching the region. Conditions will be dry under this ridge and the warm advection ahead of the next system will promote some of the mildest temperatures of the year so far with high temperatures on Friday cresting in the mid 50s over the basin and upper 40s to lower 50s in the northern valleys.
Saturday through Monday . Ensemble model average fields of motion for the GFS and ECMWF indicate a good chance of a somewhat vigorous short wave trough passage on or about Saturday . maybe Friday night or during the day Saturday depending on the particular model . which will bring the next chance of more widespread precipitation. This looks like a quick hitting system with minor snow accumulations on the higher terrain and if the transit occurs overnight Friday or early Saturday then valley precipitation will probably be non-accumulating snow. In any event the bigger story with this system will be another windy and gusty day on Saturday.
For Sunday and Monday there is some model disagreement regarding details but both the ensemble mean fields of motion suggest a split flow regime on Sunday that may direct any significant forcing to the south of the forecast area but this far out it is too early to get a good grip on this prospect so the forecast will feature unsettled and seasonably cool conditions leading into the next work week. /Fugazzi
AVIATION. 12Z TAFS: VFR conditions with mid and high level clouds expected across TAF locations through 12Z Wednesday. The approach of a weak disturbance today and tonight will promote increasing and thickening high clouds today with ceilings lowering overnight tonight but ceilings will remain VFR. After 09Z widely scattered -SHSN are possible in the vicinity of the KCOE and KPUW TAF sites with low confidence that the TAF sites will be impacted with MVFR temporary conditions. /MJF

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.
