Fxus66 kotx 230552 afdotx area forecast discussion national weather service spokane wa 1052 pm pdt Wed may 22 2019 Synopsis Temperatures will warm up the next couple of days with highs into the 70s and low 80s. Afternoon showers and thunderstorms are expected over the northern cascades Thursday afternoon but will taper off in the evening. By Friday, a weather disturbance will take up residence over western washington resulting in a good chance of showers and afternoon thunderstorms for most of the inland northwest. The disturbance will then drop south of the area for the holiday weekend with a chance of showers mainly for Saturday. Discussion Slow moving thunderstorms with heavy rain Friday and Saturday... today through Friday morning: a mostly east-northeast upper flow continues over the eastern washington and the northern panhandle region through at least Thursday morning. As the upper low over the great basin and central rockies begins to push northeast into the north central us, a more northwest upper flow will increase across the cwa. Much of the inland northwest will remain dry for the most part except for the the western areas of the CWA where the possibility of a few showers and isolated thunderstorms may develop along the northern cascades. Increased pops Thursday afternoon along will surface CAPE ranging 800-1200 j kg will increase the chances isolated thunderstorms over the area. Individual cells will be slow moving along the crest and contribute to localized, but brief rainfall. Confidence is low as to any widespread flooding concerns in the cascades Thursday afternoon. By Friday morning, the region will begin to come under the influence of a deepening upper low over southern bc dropping southeast into north-central washington. Highs over the CWA will range in the mid to high 70s across eastern washington and the northern panhandle with parts of the columbia basin topping out in the low 80s. Aky Friday through Sunday night: an upper level low pressure system will drop down out of bc over the region on Friday. Models are in good agreement with a closed low forming over the north cascades by Friday afternoon. There will be very little flow over the region, but positive vorticity advection at upper levels will produce a modest amount of synoptic scale lift across eastern wa and the northern id panhandle. Ample moisture will be drawn up into the region ahead of the low with p-wats of near 0.80 inches and surface dew points increasing into the upper 40s to lower 50s. The moisture content will be slightly less than the environment that thunderstorms developed in last Thursday, but at least comparable. Where the atmosphere will be noticeably different is in the instability. There will be more cloud cover at the start of the day compared to what was observed last Thursday. This will result in cooler afternoon temperatures and weaker capes as a result. Surface based CAPE values will peak on the order of 500-1000 j kg, and most areas will probably be on the lower end of that range. The main uncertainty will be how much in way of Sun breaks will we see, which is tough to really tell at this point. These will be the spots that see the best potential to destabilize and see afternoon convection. Thunderstorms are not expected to be as strong as those that developed last Thursday

because of the lower CAPE values. As a result, rain rates will not be as intense, but are still expected to contain cores of very heavy rainfall. Storms will also be slower moving and the slow storm motion will be a problematic factor to consider when watching for the potential of flash flooding, especially in steeper terrain and more so over areas with recent burn scars. Flash flooding risk will be highest for these burn scar locations, but is not restricted only to these areas. Thunderstorms will also be possible Saturday and again Sunday. Main threat for thunderstorms on Saturday will be over the northern mountains and over the higher terrain the panhandle. The extent of thunderstorm coverage should be less on Saturday. They will still contain cores of very rain though, but there is more uncertainty with movement as some guidance indicates potential for faster storm motions and others have weak steering flow aloft. So, uncertainty in the details for Saturday is higher. The upper level low will begin to pull away to the south on Sunday with higher pressure building in. Best chances for showers and thunderstorms will be over extreme southeast wa and into the southern id panhandle. Svh Monday through Wednesday: there is good agreement between the medium range models that showers will decreasing Monday into Tuesday as our weekend trough drifts across the great basin into the central rockies. The GFS and ECMWF forecast enough residual instability Monday afternoon for the mention of scattered showers and embedded thunderstorms over the cascades as well as the southern idaho panhandle and southeast washington. Elsewhere, the memorial day holiday should end on a pleasant note with dry weather, afternoon temperatures mainly in the 70s, and north winds in the 5 to 15 mph range. Low chances for showers remain in the forecast for the mountains of the idaho panhandle Tuesday and Wednesday, but if any rain does fall it should be light in the absence of any significant synoptic scale feature to act as a lifting mechanism. Afternoon temperatures will be in the mid 70s to low 80s... About 5 to 8 degrees above average as we round out the month of may. Gkoch Aviation 06z tafs: partial clearing is expected for TAF locations. Thursday aft 19z CU will pop across the region. Showers and thunderstorms will be possible for the cascades, but only have mention of vcsh for eat attm.

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.
