Area forecast discussion National Weather Service Spokane Washington 440 am PDT Sat Oct 25 2014 Synopsis... A series of systems will pass through the region during the period. The first system today is expected to bring the threat of isolated thunderstorms and high winds to the region. Remnants of Hurricane Ana on Tuesday will deliver widespread rainfall to the inland northwest. Another rain producing system is possible by next weekend. && Discussion... today and tonight... taking a look at the big picture across the country, the one feature that really stands out is the deep upper level trof approaching the West Coast. This vigorous system will usher in quite a bit of high impact weather over the next 36 hours. Overview: at 12z, a 986 mb low is moving rapidly northeast toward the Washington and Oregon coast...and will make landfall this afternoon at about 993 mb between Astoria and Aberdeen. The warm front that lifted north into British Columbia overnight will be replaced by a cold front ahead of the center of low pressure. Before the front pushes inland, much of the inland northwest will see at least a partial clearing. The clearing skies coupled with the warm temperatures should further destabilize the atmosphere...resulting in the possibility of isolated thunderstorms. Thunderstorms? But first, a line of showers will develop along the cold front...ushering clouds quickly back across the inland northwest early this afternoon. The cold air aloft will further destabilize the atmosphere leading to numerous showers by the evening hours with the aforementioned isolated rumble of thunder. While we painted much of eastern Washington and the entire Idaho Panhandle with isolated thunderstorms, the best chance will be late this evening over extreme southeastern Washington and the central Panhandle. The models have not been too aggressive with the chances of thunder but after bumping up afternoon high temperatures due to the anticipated clearing in the warm sector, the NAM and sref especially are showing enough instability to warrant the isolated chance. Either way, widespread showers will impact the region late afternoon through the evening hours with localized heavy downpours possible. Wind: the biggest impact from this storm system will be the wind. As the main line of Showers Pass through the region late in the evening, the pressure gradient will tighten considerably. Common with this storm path, a Lee-side low will develop east of the Canadian rockies over Alberta. The low that moves inland this afternoon will eventually merge with the Lee-side low. High pressure building southwest of the region coupled with the 994 mb low to our northeast will squeeze the pressure gradient and result in strong winds. A Wind Advisory that was issued earlier will be updated momentarily to include Spokane Metro with gusts to 50 mph not out of the question. The peak of the event will be overnight...midnight through sunrise. In a way we are fortunate that the timing is not during Max heating. The overnight hours will work against the strongest winds mixing down to the surface. Despite the fortunate timing, we are still anticipating several impacts from this storm. Impacts: the main impacts from this storm will be the possibility of light weight objects being picked up and thrown by the gusty winds. This includes branches that will likely fall on power lines and result in local power outages. Caution is also advised on the roadways with dangerous Crosswinds affecting high profile vehicles. Lastly and not nearly as important...but this storm will bring an end to much of the very Scenic fall foliage. /Ab Sunday through monday: winds will be on the decrease during Sunday as the deep low pressure system moves east of our area. These situations are often tricky. The pressure gradient is decreasing which should allow winds to decrease, but the daytime heating allows more momentum mixing from aloft. Winds will be breezy to windy through much of the day. Showers will mainly be confined to the Panhandle and northeast mountains, but there's actually enough afternoon instability to allow showers to develop over the eastern basin. These showers should die off Sunday evening. As the upper trough swings through the area, the flow on the backside of the trough turns to northwesterly, allowing cooler air to filter into the inland northwest. This will result in the coolest day of the autumn so far. A few locations may not reach 50f on Monday. The Panhandle and extreme eastern Washington will probably start the day with a stratus layer that will slowly burn off by midday. Rj Monday night through wednesday: a southwest flow pattern will carry the remnants of Hurricane Ana through the Pacific northwest during this period. The eastern side of the Cascades will begin to receive precip beginning Monday night. The moisture will continue to progress west to east through the inland northwest on Tuesday morning. With snow levels expected to be around four to five thousand feet, the higher elevations could receive a light dusting of snow with rain for the valleys. This system is expected to bring more than half an inch of precip to the Cascades. The Waterville Plateau could see a couple tenths of an inch. The extreme eastern Washington and Idaho Panhandle could get around a quarter of an inch of rain. Winds with this system will remain fairly light as gusts could reach around 18 miles per hour. High temperatures will range from the mid 40s to 50s for most habitated locations. Thursday through saturday: the models disagree with this period. The European model (ecmwf) is keeping a strong ridge over the region than the GFS for this period. The GFS will begin to bring another round of precip into the region on Thursday afternoon while the European model (ecmwf) keeps it west of the Cascades until late Saturday. The pops were dropped to a slight chance for most of the Columbia Basin. Temperatures for this period will still be several degrees above normal with highs near 60 and lows near 40. /Jdc Aviation... 06z tafs: a warm front lifting into eastern Washington and north Idaho will bring areas of mainly light rain. The band of light rain has lifted north of all taf sites. Low level moisture and light winds behind the warm front will promote low stratus and patchy fog for keat and kmwh through at least 18z Saturday. Confidence is low that MVFR cigs may develop at klws but light downsloping winds may keep VFR conditions there. Shower threat develops again through the afternoon Saturday. This will be accompanied by increased winds with gusts increasing to 25 to 30 kts after 03z Sunday. 12z tafs: the warm front lifted north with light rain in most areas. Now that we are in the warm sector, expected a bit more fog but the high clouds and breezy conditions are preventing any widespread fog from developing. The exception is keat where a IFR ceilings persist. This morning we expect conditions to improve briefly before winds in most taf locations turn southeast and eventually southwest. The approaching cold front will bring widespread rain showers with the very slight chance of thunderstorms to the eastern sites...not enough of a threat to include in the taf. Ceilings and visibilities will remain marginal to VFR in rain as winds continue to turn southwesterly and very gusty by late evening. Updates to tafs at 12z were limited to adjusting for improved morning ceilings and adding stronger winds in the last 6 hours. && Preliminary point temps/pops...
