Area Forecast Discussion National Weather Service Spokane WA 347 AM PST Sun Dec 8 2019
SYNOPSIS. An exiting storm system will bring lingering valley rain and mountain snow showers to the Idaho Panhandle today with lots of low clouds and patchy fog in the Columbia Basin. Drier weather is expected Monday and Tuesday followed by chances for rain and mountain snow Wednesday and the end of the week.
DISCUSSION. Today through Monday night . An upper level trough axis running form north Idaho to California early this morning will move east today allowing dry northerly flow over the forecasts area in it's wake as an sharp upper level ridge builds along the northwest coast today. As the trough exits some lingering showers orographically driving into the Idaho panhandle will persist through the morning and taper off during the afternoon. The Winter Weather Advisory for the Shoshone County mountains will likely be allowed to expire at 10 AM this morning as showers wind down.
While dry northerly flow aloft begins today over the rest of the region . the very moist low level boundary layer will manifest itself as widespread low clouds and patchy fog until appreciable low level air can filter through the northern gaps and erode the stratus. The Okanogan Valley will be the main conduit for this invasion and so the western basin will see the most noticeable improvement this morning with a slow erosion of low clouds form west to east during the afternoon. High temperatures today will be impacted by this stratus field . still above average for this time of year but an uncomfortably damp above average.
For tonight through Monday night patchy fog and fields of low clouds will slosh around the basin and valleys as the building ridge aloft stabilizes the air mass and promotes an inversion scenario which may lead to some air quality deterioration over the next few days. No storm systems or precipitation chances are expected through the beginning of the week. /Fugazzi
Tuesday through Saturday: Ridge remains over the Pac NW Tuesday for a dry forecast. A weather disturbance moves into the ridge Tuesday night and exits Wednesday. This will provide some brief precipitation to the Cascades and extreme eastern WA and the ID Panhandle with precip decreasing through the day. Wednesday night the ridge will begin to flatten and a low in the Gulf of Alaska will begin to send numerous disturbances/pieces of energy into the Pac NW. Current models/ensembles suggest the the best chance of precip will be Wed night-Thur night, but the weekend will still remain unsettled. Have increased the winds for Thur through Fri morning across portions of SE WA as a strong jet moves into OR and southern WA. Temperatures will be several degrees above average for this time of the year. Highs in the mid 30s to low 40s and lows in the mid 20s to mid 30s is expected. Temps and time of day of precip will have a large impact on whether valleys will pick up some snow or not. The mountains should see all snow. Even if we do get snow Wed night, Thursday will be our warmest day of the week and all the snow will likely melt, or snow will turn to rain making a slushy situation. Unfortunately (fortunately, depending on how you look at it) temps remain pretty warm through Friday for most valleys to see temps warm enough for some valley rain in the afternoon. It isn't until Saturday that most valleys have a decent shot of seeing precip mostly in the form of snow. (except the deep Columbia Basin and Palouse/LC Valley where it will still be rain). /Nisbet
AVIATION. 12Z TAFS: A moist boundary layer as a result of recent rain will promote widespread MVFR and local IFR conditions through the morning hours. A push of dry air is moving out of Canada through northern valleys this morning and will probably bring improving conditions to the KEAT . KMWH . KGEG . KSFF and KCOE TAf sites between 18Z and 21Z today . while the KPUW TAF site will be subject to deterioration as moist upslope flow promotes continued IFR and LIFR conditions until later in the afternoon when slow improvement to MVFR conditions is expected. Tonight the gradient will weaken and shift to the southeast which should allow improvement to the KPUW and KLWS TAF sites to VFR conditions but promote deterioration once again to the KEAT . KMWH . KGEG and KSFF/KCOE TAF sites after 06Z tonight. /MJF

I do not sell or share any user data or anything else for that matter. I do not keep site logs longer than I need to to keep bad actors off the site. Basically, I delete them after looking at them.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
