Scientific Forecaster Discussion

000 fxus66 kotx 151129 afdotx Area forecast discussion National Weather Service Spokane Washington 429 am PDT Mon Oct 15 2018 Synopsis... a ridge of high pressure will persist over the inland northwest through the week. This will bring mostly clear skies, dry weather, light winds with chilly morning temperatures and mild afternoons highs. && Discussion... today through tuesday: the upper level ridge will continue to strengthen over the Pacific northwest through Tuesday. We may see some thin cirrus from time to time today especially across north ID, with clear skies expected on Tuesday. Temperatures today will be around average for this time of the year, or valley temps in the upper 50s to lower 60s. Then Tuesday we will see about 2 to 5 degrees of warming. Overnight low temperatures will remain cool for this time of the year with most low elevation locations at or below freezing. /Nisbet Tuesday night through Sunday...the upcoming week will continue to to be dry with generally clear skies or occasionally partly cloudy with variable high clouds. Winds will be light and temperatures will gradually increase each day to above normal...in the lower to mid 60s during the day by next weekend. Mornings will be seasonably cool. This quiet and benign pattern will be compliments of a mean upper level ridge with axis just off the coast with the forecast area under the dry northwesterly flow down the eastern flank...with the ridge axis occasionally shifting over the region especially by the weekend. The only mentionable weather issues will be the Prospect of patchy morning fog in sheltered valleys and river bottoms in the early mornings...and the potential for deteriorating air quality later this week as a persistent mid level subsidence inversion limits mixing heights and light winds may prove incapable of adequately ventilating accumulated smoke and pollutants in the basin and valleys around the region. This is not a sure bet and subsequent shifts over the next few days will need to monitor this potential and coordinate with regional air quality folks before achieving enough confidence to issue any air quality products. /Fugazzi && Aviation... 12z tafs: VFR conditions will prevail for the next 24+ hrs. Cirrus from time to time will move over north Idaho and extreme East Washington. && Preliminary point temps/pops...
