(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 kotx 262330 afdotx area forecast discussion national weather service spokane wa 430 pm pdt Fri may 26 2017 Synopsis High pressure builds over the region this weekend. A few showers and isolated thunderstorms are possible around the idaho panhandle this afternoon and evening. Limited thunderstorm chances develop around the cascades, and perhaps the canadian border, each afternoon between Sunday and Tuesday. Otherwise expect dry, warm weather into early next week, with afternoon highs in the 80s. This mild weather will contribute to rises on rivers in central and north central washington. A threat of unsettled weather returns in the middle to late next week, with slightly cooler temperatures. Discussion Tonight and tomorrow: the northerly flow allowing weak disturbances to fire off very light and spotty convection over portions of north idaho this afternoon and early evening gets shunted to the east tonight as an upper level ridge of high pressure amplifies over eastern washington and north idaho while the ridge axis migrates from near the coast today to over the cascades tomorrow. This will result in a warming and drying trend with forecast temperatures above normal for this time of year, especially daytime highs tomorrow. Surface winds are expected to remain fairly diurnal upslope to upvalley during the day transitioning to downslope and downvalley winds overnight. Pelatti Sunday through Tuesday: the two points of interest in the extended period are the unseasonably warm temperatures and the eventual return of shower and thunderstorm chances to the region. On Sunday we're squarely under a stabilizing ridge of high pressure that will hang around through at least the memorial day weekend. This is great news to those that are used to our typically cooler holidays in years past. We will be clear and dry with temperatures on the increase each day through Tuesday as the ridge axis approaches and 850 mb temps reach near 19c. High temperatures will be 10-15 degrees above average for late may, with highs in the mid 80s and even the 90s in parts of the deep columbia basin. This warming will lead to increased mountain snow melt and rises on area river and streams over the next few days. Keep in mind that water temperatures are still quite cold given this snowmelt. While the ridge will be the dominating player, some scattered mountain |
showers will be possible rounding the ridge each afternoon evening beginning on Sunday and increasing in coverage each afternoon. Flow becomes southwest on Sunday, advecting more moisture over central wa at the mid levels. This, together with orographic lift will be able to initiate some mountain showers. Warm temps and increasing lapse rates will give enough instability over the mountains for some weak thunderstorm potential as well. Coverage increases over the mountains on Monday afternoon and even more so late Tuesday. Tuesday night through Friday: models begin to diverge on exactly when the ridge will break down. While the GFS has been the most bullish in bringing a trough in late Tuesday Wednesday, the ec and canadian models are beginning to come into agreement with this earlier timing. This means we'll see a bit of a cool down and a good chance for showers and thunderstorms on Wednesday and Thursday as the negatively tilted trough moves through. Behind the trough flow becomes more zonal with a few ripples in the flow capable of bringing hit and miss showers on Friday. Bw Aviation 00z tafs: showers and isolated thunderstorms over the southern to central idaho panhandle will dissipate quickly this evening. A strong ridge of high pressure will build further into the region on Saturday. Flat cumulus will be possible over the higher terrain Saturday afternoon; otherwise,VFR conditions and weak winds will continue across the region through 00z Sunday.

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. |
