Area forecast discussion National Weather Service Spokane Washington 520 am PDT Wednesday Oct 22 2014 Synopsis... through Wednesday night, a very moist frontal boundary will produce heavy precipitation for the Cascades and possibly the mountains of north Idaho. Though the heavy rains end Thursday night, the pattern will continue to be active into early next week. This includes the potential for widespread rain Friday into Saturday, then again Monday into Tuesday, as moisture associated with former typhoons makes its way toward the Pacific northwest. && Discussion... today through tonight...wet period awaits most of the inland northwest during this period. The latest satellite images are showing a very moist occluded front extending from deep upper level low over the eastern Gulf of Alaska south-southwest through Vancouver Island and the olympic peninsula. The blended precipitable water product shows a very impressive atmospheric river streaming from west of the dateline all the way to the Washington coast. Precipitable water values within this front ranged from 1 to 1.3 inches...which is about 2 Standard deviations above normal for this time of year. This moisture will eventually push east of the Cascades...but the question is when. Over the past several hours the eastward progression of the front has slowed...likely in response to a shortwave trough forming near 42/135. This should delay the onset of the precipitation in the Lee of the Cascades. 00z models aren't depicting this slowing trend well....however the new 06z NAM is doing much better. Through late morning...most of the precipitation will occur west of a line from Colville .To rtzville.. by late afternoon...that line will extend from Kellogg to the Blue Mountains. Once the precipitation begins...it will continue through much of the night for most of the night as low- level moisture transport and isentropic ascent look very formidable. The only drying trend during this period will occur after midnight in the Lee of the Cascades...as the mid-level flow trends to the west and the precipitable water plume shifts south and east of that area. Quantitative precipitation forecast amounts during this period will be impressive with the heaviest amounts expected over the northern Cascades. Values ranging from 1-1.5 inches will be possible...with amounts around an inch extending across the northern mountains of Washington. Despite the lofty precipitation amounts...Hydro problems if any...will be minor due to relatively dry in situ conditions and low river levels...combined with a slow but steady stratiform precipitation regime (as opposed to a rapid convective event). If problems were to occur...it would likely be near the Cascade burn scars. We will continue to issue hydrological statements to address this issue. The location with the lightest precipitation amounts will be over the lc valley...due the the late onset of the precipitation (last area for front to arrive) and persistent southerly downslope flow off The Blues. Aside from the widespread threat of precipitation...we are looking at another warm and perhaps windy day. Until the front and precipitation arrives...most of the area will be subject to moderate south-southeast winds...combined with warm 850 mb temperatures. Between late afternoon and early evening...850 mb temps surge above 10c over the southeast quarter of Washington and the southern Idaho Panhandle. Enhanced mixing potential will allow temperatures to surge into the mid to upper 60s (if not slightly warmer) across southeast Washington and adjacent portions of Idaho. Meanwhile temperatures will be significantly cooler across the northwest portions of the forecast area. With the rain likely to develop early...the impacts of diurnal heating will be largely mitigated. Highs in these areas won't be much warmer than the current temperatures which suggests readings in the mid 50s. Fx Thurs through Sat: for thurs, we slowly progressed the frontal boundary and associated rich moisture plume through southeast WA and the cntrl Idaho Panhandle. The tricky part will be determining how far east across the Cascades and upper Columbia Basin to bring the Post-frontal dry slot as well as steep mid-level lapse rates. It's possible we'll see some cloud breaks thurs afternoon that would help to enhance any sfc-based instability and produce localized heavier embedded showers. This will be especially true for the Cascades as an inbound vort Max reaches northwest WA by afternoon. We increased winds as well for thurs as the vertical profile becomes nearly unidirectional from the SW in the dry slot, with 850mb winds around 30 kts. Once the vort Max moves into srn BC, rapidly rising hts aloft ahead of a warm front over Oregon will help to quickly end the persistent heavy pcpn threat thurs nt. Concerning this warm front, we made some significant changes to the timing of the pcpn as this front moves north across ern WA. This includes slowing down the onset of light rain, keeping nrn WA and much of the north Idaho Panhandle near British Columbia dry for Fri.Bz Sunday through wednesday: the models are indicating a dry period on Sunday followed by an extended period of rainshowers through midweek with multiple systems passing through the region. The temperatures are expected to be near the season normals with highs around mid 50s and lows around 40. /Jdc && Aviation... 12z tafs: focus for this period will center on strong low-level warm air and moisture advection ahead of front currently on the Washington coast. As the best advection heads east of the Cascades...all sites will see an increasing and lowering cloud trend as well as an increasing chance of rain. The rain will become widespread before 18z at mwh and eat...and hold off closer to 00z or a little later for the remaining sites. The last location expected to see rain is lws due to downslope southerly winds. Generally speaking...strong warm air advection cases do not lead to widespread IFR cigs however brief MVFR cigs will be possible...especially for eat and mwh later today and the geg-Coe corridor later this evening. Threat was too small to list as a prevailing condition in forecast. Fx && Preliminary point temps/pops...
