NWS Forecaster Discussion
Area forecast discussion National Weather Service Spokane Washington 457 PM PDT Thu may 23 2013 Synopsis... cool and showery weather will continue through Saturday then a subtle warming and drying trend is anticipated by Monday as the persistent upper-level low moves out of the area. The break will be short-lived as another cool and showery pattern returns around the middle of next week. && Discussion... Tonight and Friday...a large closed low near the central Washington coast this afternoon will move southeast towards Portland overnight. As it does so most of the rain associated with this low will remain south and west of the area. However...a cold pool aloft associated with this large low will result in an unstable atmosphere through early this evening promoting isolated showers except for a bit more coverage near the Cascades given closer proximity to low. Laps data this afternoon also shows surface based cape values of 200-400 j/kg near the Cascades, and over the Blue Mountains where a few lightning strikes are possible. Once daytime heating is lost, these showers will fall apart with dry conditions expected for the late evening and overnight hours. Another cool night is in store with localized freezing temperatures possible in the Okanogan Highlands and northeast Washington valleys where skies are expected to clear more significantly overnight. On Friday the low will move east across south central Washington in the morning...and then rotate northeast towards the Spokane and Palouse areas in the early afternoon...and finally into the central Panhandle mountains mid to late afternoon. This is the solution the European model (ecmwf) and NAM models show and is preferred...compared to the slightly more southerly GFS track. This will promote a cool and showery day over the inland northwest with the greatest coverage of showers focused along the low track and in the mountains. There will be a slight chance of thunderstorms Friday afternoon as well over the area with forecast convective available potential energy of 200-500 j/kg over the region. Jw Friday night through Sunday night: the upper-level low that has been parked over the region the last few days will continue to have an influence on the weather but does show signs of filling/warming. This will translate into less widespread and weaker shower activity each afternoon; especially across the Columbia Basin and into the latter half of the Holiday weekend. There are a few weak waves embedded within the parent low which will keep a slight chance for pops during the overnight periods at times...but in general, most shower activity will be middle to late afternoon and focused over the northern and eastern mountains. The best chance for thunderstorms will be Friday evening...with very small chances Saturday...then a slight threat near The Blues and Camas Prairie Sunday. Temperatures over the period will be slowly climbing back near seasonal readings or upper 60's to mid 70's. /Sb Monday through Thursday...some significant shortwave features of note to lock in on and add more detail courtesy of general longwave trof lingering and influencing a good portion of the western United States through this time interval. Significant features of note include what could be described as a deformation zone of sorts sandwiched between the upper right corner of a large low embedded in the longwave trof that gets squashed against higher pressure influencing central Canada that the GFS in particular has lingering on and influencing Wednesday and Thursday with continued wet weather. Otherwise Monday into very early Tuesday morning appear to be the interval potentially least cluttered with shortwave triggers so it remains assigned with the lowest pops. Tuesday afternoon/evening are hinted at as having negatively tilted trof passing as a kicker thus the pops and precipitation amounts show an increase. Due to this longwave trof pattern persisting forecast temperatures will generally remain on the cool side of what would be considered normal for this time of year through this time interval. /Pelatti && Aviation... 00z tafs: afternoon showers are expected until sunset over mainly the higher terrain; although, we will see some isolated showers develop over the basin as well. The main threat for thunderstorms will be over the NE blue mtns through 03z and may hold together long enough to impact klws. Skies are expected to clear out over much of the northern half of the area tonight and we may see some fog develop across these mountain valleys. Fog coverage will likely be less compared to early this morning as the boundary layer will be slightly drier tonight; however, some fog could form in the vicinity of ksff, but confidence is low at this time and was not mentioned in the taf. The main low generating these showers will slowly drift into eastern Washington by Friday morning with showers expected to develop from south to north through Friday over the region. Isolated thunderstorms will be possible across the region Friday afternoon, but confidence is too low at this time to include mention of thunder at any taf site at this time. /Svh && Preliminary point temps/pops...
