Area forecast discussion National Weather Service Spokane Washington 504 PM PDT Thursday Apr 28 2016 Synopsis... a cooler system will bring increased cloud cover and areas of rain across eastern Washington and north Idaho on Friday. High pressure will build in Saturday through Monday resulting in a warming trend. Temperatures early next week will climb to above normal once again...with highs mainly in the mid 70s to lower 80s. High pressure will move east for the middle of next week allowing increased moisture to move in from the south...resulting in a chance for showers and thunderstorms. && Discussion... tonight through Friday night: satellite imagery shows a weak upper level low pressure circulation centered over southwest Montana. The track of this low will be peculiar in that it will lift north- northwest into northwest Montana through tonight into Friday. Much of this moisture can actually be tracked from off of the Gulf of Mexico rather than off of the eastern Pacific. Higher clouds are already streaming in across the Idaho Panhandle this afternoon. There is an easterly pressure gradient across the Panhandle, which is resulting in downsloping off of the higher terrain. This gradient will weaken overnight and flip to a more westerly orientation. It will be during the late nighttime hours into the morning hours on Friday when lower levels will really begin to moisten up and orographics will play a bigger factor. Models indicate a healthy amount of precip possible across the Idaho Panhandle. The flow pattern at 700 mbs will be a bit more northwesterly than due westerly where precip will be most favorable across the central Panhandle mtns and extend down toward the Camas Prairie. Around a half of an inch of precip will be possible across these areas. Expect a steady rainfall through Friday morning then transition to showers by the afternoon. Showers will expand a bit further west in the afternoon where the eastern basin and northeast mtns will see a better chance for precip. Much of the region will be cloudy tomorrow even if not under rain showers, which will result in a noticeably cooler day compared to today. Many locations in the Idaho Panhandle are only expected to warm up into the lower 50s. /Svh Saturday through Thursday...an upper level ridge will build over the region over the weekend into early next week bringing a warming and drying trend. A few showers are expected to linger over the Idaho Panhandle on Saturday...otherwise a dry forecast Saturday through Monday morning. Monday afternoon the ridge axis shifts east of the area allowing a weak wave to come around the high and then up along the Cascades. Models are not very consistent with this idea...but enough instability and lift is shown by some guidance to warrant a slight chance of thunderstorms. For Tuesday through Thursday an amplified pattern sets up with the upper ridge east of the area over the Rocky Mountain states...and a trough off the West Coast. This places the inland northwest in a deep southerly flow aloft. This will result in an increase in mid level moisture as well as instability over the area. Thus an increasing chance for showers and thunderstorms is expected. The GFS shows cape values by next Thursday increasing to 1000-1500 j/kg with 25-40 kts of 0-6km wind shear. This could support stronger storms...but since this is several days out confidence is low in the details. The building ridge this weekend followed by a mild southerly flow for the early to middle of next week will result in a warming trend through Tuesday or Wednesday. 850mb temperatures rising into the 15-18c range will yield valleys highs climbing into the mid 70s to lower 80s...which is about 15 degrees above normal. Jw && Aviation... 00z tafs: the region is under a broad upper level trough of low pressure. A weak circulation over SW Montana will increase moisture over the region. -Shra over the Okanogan Highlands and Cascades will move southeast and continue through 03z. Rain will increase overnight into Friday morning in extreme eastern Washington and in the Idaho Panhandle. Expect MVFR cigs and vis possible at the kgeg, ksff, kpuw and kcoe taf sites after 09z. Cigs will improve in the afternoon but showers will still be likely across the region. && Preliminary point temps/pops...
