Area forecast discussion National Weather Service Spokane Washington 433 PM PDT sun Oct 19 2014 Synopsis... temperatures Monday will continue to run be well above average with afternoon readings in the upper 60s to low 70s. Clouds will be on the increase Monday ahead of the next frontal system. Rainy and unsettled weather will return Monday night into Tuesday. Significant rain is expected Wednesday into Thursday for much of the region. && Discussion... tonight through Monday night...satellite this afternoon indicates the forecast area is under a southerly flow regime between a departing upper level ridge with axis over Montana and an incoming Gulf of Alaska trough. The deep moisture feed ahead of this trough which will evolve into a slow moving frontal band is currently approaching the Pacific coast. The arrival and passage of this initial front will dominate the next 24 to 36 hours. Models are in good agreement in elongating this trough as it approaches and thus slowing down the eastward progression tonight and Monday...and then splitting off the southern trough base dynamic region over the Great Basin while ejecting a weakened northern branch wave through the region Monday evening and into Tuesday morning. The ramifications of this evolution will be generally increasing mid and high clouds tonight...followed by a general increase in shower chances Monday mainly over the Cascades and western basin as the slow moving front crawls off the Cascades and acts as a focusing mechanism for the moisture feed Welling up in the southerly flow. Occasional showers are a near certainty in the Cascade mountains and the Okanogan Highlands where orography will augment the frontal lift. Over The Lowlands such as Wenatchee and Omak and as far east as Moses Lake and Republic showers will be more spotty and hit-and-miss but none-the-less present. The eastern half of the forecast area will likely escape with one more dry and mild but cloudy day. On Monday night the split occurs causing the northern branch to become more westerly flow driven and thus allows it to speed up the progression of the front. This period will bring the greatest chance of showers to the eastern half of the forecast area with the best chance of a tenth or two of rain over the Palouse and points south as well as the Idaho Panhandle mountains between midnight and dawn Tuesday...with scattered/occasional showers to the north of these zones. /Fugazzi Tuesday: the region will be under a weakly unstable and cooler Post frontal air mass. Best chances for precip will be in the more favorable upslope areas in the Idaho Panhandle where westerly flow will help force some lingering showers. Temperatures will drop to near normal and will be much cooler across extreme eastern Washington and in the Idaho Panhandle compared to Monday. ..Pacific moisture will bring soaking rains across the region and high elevation snow in the Cascades for middle week... Tuesday night through thursday: a long duration atmospheric river event is expected at The Heart of the work week. A plume of moisture with tropical connections will be oriented at the northwest. This plume of moisture will be drawn up from between 170w to 180w longitude and 25n to 30n latitude. Current satellite imagery shows active convection occurring in this portion of the sub- tropics this afternoon. This convection is lofting a considerable amount of moisture into the atmosphere, which will be entrained into the westerlies and ride the polar jet stream. This will also include moisture from Hurricane Ana that is currently impacting the Hawaiian islands. P-wats with the moisture plume will be around 1.25 inches as it impacts western Washington beginning Tuesday night. This will be roughly 2 to 3 Standard deviations higher than what is typically observed this time of the year. There is still some model uncertainty with the shortwaves that rotate in around a deep upper level low pressure system in the Gulf of Alaska. A moderate to strong jet streak of around 165 kts will be directed toward the northwest. This will result in good jet dynamics acting as a forcing mechanism. The topography will also play a major role in location and intensity of the precip. Strong westerly to southwesterly flow at low to mid levels will result in the bulk of this moisture falling on the windward slopes of the Cascade mtns. This will result in heavy precip across the Cascade crest. Conditions look to be wet along the Lee side of the Cascade mtns as well. Winds at 850 mbs do indicate a southerly to southeasterly component, which will result in some upslope flow across these areas as well. Other favorable locations for moderate to heavy precip will be across the northern mtns in eastern Washington and in the Idaho Panhandle. Precip is expected to hold off in the Panhandle until Wednesday, but will continue to be wet through at least Thursday. * Rain: amounts will vary considerable across the region. The east slopes of the Cascade mtns will see a range of 0.75 inches to over 3 inches at the Cascade crest. A secondary maximum for rainfall will be across the Okanogan Highlands to the northern Panhandle with around 0.75 to 1.25 inches possible. The central Panhandle mtns will likely see moderate to heavy rains as well with up to an inch or so expected. Confidence is a bit lower in this area as models differ on how fast to push across the cold front. If there is a slower progression of the cold front, then the central Panhandle mtns will see more rainfall than forecasted. The greater basin will see amounts generally between 0.25 and 0.75 inches. * Potential flooding impacts: there will be a concern for localized flooding, mainly across the east slopes of the northern Cascades. This will be of special concern on recent burn scars with mud and/or debris flows possible. Rainfall intensity should not be high enough for flash flooding, but will need to be monitored during the event. Considering that this will be the first significant rainfall for the season, most other areas will see a lower risk for flooding concerns. * Snow: High Mountain snowfall is expected across the Cascade mtns with snow levels at around 6,000 feet. These snow levels may start out a bit higher at the beginning of the event, but will drop through Thursday. Snowfall amounts of over a foot will be possible above the 6,000 foot level. * Temperatures: mild overnight low temperatures are expected during this period; however, temperatures will not warm much during the day with highs near normal in the 50s to low 60s. /Svh Thursday night thru saturday: a continuation of the moist flow with a series of waves in southwest flow is expected for the first part of this period. The threat of mud/debris flows will remain as the burn scar areas could possibly receive additional rain. Snow levels will remain steady in the 5000 to 6000 foot level with additional amounts expected. Temperatures will remain steady as well with the steady flow from the southwest. Current model solutions show an end to the moisture on Saturday as a weak ridge moves in. Jl Saturday night through sunday: a ridge over the region will push east and a trough will move into the area for this period. The European model (ecmwf) is still slower than the GFS by about 12 hours. The impacts from this trough are mainly mountain rain showers. Some valley locations could see a stray shower. The temperatures will be on a cooling trend but still to warm for mountain snow. Highs are expected to be in the 50s and lows around 40. /Jdc && Aviation... 00z tafs: some denser high clouds associated with the weak cold frontal zone trailing to the south of a weak exiting low pressure system remains overhead this evening but is making progress eastward and should clear the region early overnight. A somewhat more intense baroclinic zone off the coast separating cooler conditionally unstable air to the northwest has more shortwaves digging into its west edge and making more inflection points as it moves east and the far east edge is associated with the radar returns showing up off the Washington and Oregon coast. Expectation is this band will work its way into the region as well spreading thickening clouds from west to east with some light rain showers near the Cascades to Wenatchee to Moses Lake areas near 21z Monday. /Pelatti && Preliminary point temps/pops...
