Area Forecast Discussion National Weather Service Spokane WA Issued by National Weather Service Pendleton OR 1026 AM PDT Mon Oct 18 2021

SYNOPSIS. Most of the region will remain dry and warm through Tuesday, but look for a mix of sun and clouds. A period of light rain is possible Wednesday. A wetter pattern is forecast for the Inland Northwest for the end of the week into next weekend, with temperatures cooling closer to normal.

AVIATION. 18Z TAFS: VFR conditions are expected through the next 24 hours. Mid and high clouds will filter into far southeast WA and the central ID panhandle today. Light diurnally driven winds around 10 kts or less. Patchy haze/fog will be possible in favored areas early Tuesday morning, but is not expected to impact airfields. ML

PREV DISCUSSION. /issued 417 AM PDT Mon Oct 18 2021/

DISCUSSION . Monday and Tuesday: Eastern Washington and northern Idaho will be on the northern fringe of a deep trough that is tracking through the Great Basin today. This will bring clouds and another mild, seasonal temperature day for the region. Tuesday will actually feature much of the same weather as we become influenced by weak ridging between weather systems and may see only the slightest change in daytime temperatures for locations east of the Cascades.

Wednesday: Our next set of weather systems will begin to take aim at the West Coast starting Wednesday and will remain in an unsettled pattern for the next week or more. The long range ensemble guidance would suggest several shortwaves will move through the Northwest with a parent trough positioned off the coast of Washington State/British Columbia. Our first trough on Wednesday becomes negatively tilted before it moves inland and the moisture plume is more directed into northern California and Oregon. By the time the energy from the shortwave tracks through north central Oregon into the Columbia Basin around the Cascades, much of the forcing will aide in the track of the wave north into Canada and will bring more clouds and some lighter precipitation. Right now the forecast has around 0.10" to 0.15" of precip. Southerly winds will become breezy with gusts around 10 to 25 mph. This is expected to be a typical run-of-the-mill light rain Fall day. /Dewey

Thursday: Looking more and more like a dry day - a break between precipitation systems. Temperatures will recover a little bit from a cooler Wednesday; about 5 to 10 degrees above average in the 60s for most of the area. Winds will be relatively normal with gusts up to 20 mph possible in the Columbia Basin.

Thursday night through Sunday: A wetter period with widespread rain and breezy winds . and models diverge greatly on timing and intensity. Max temperatures will cool to the 50s from the cloud cover/rainfall and with the help from a cooler airmass moving in Friday. However southwest flow and warm advection (and the effects of overnight cloud cover) will keep us from dropping to widespread lows below freezing. There are 2 end of the week systems we're keeping an eye on. * System 1: Roughly Friday . may begin Thursday night and be out of the area Friday afternoon or arrive later and exit Saturday morning. Latest model runs support possibly around a quarter of an inch in parts of the Basin and eastern Washington. This system elongates and weakens when it reaches the coast, so it may still be a couple of model runs before there is consensus on how much it slows down and how much rainfall it can produce. * System 2: Saturday or Sunday . depending on which model solution reality tilts toward. Much of the energy associated with the Friday system regroups near the Gulf of Alaska and approaches during the weekend, potentially from the southwest instead of our typical cross-Cascades system. Saturday has a chance at being another in-between-systems day, but no promises . RC
