Fxus66 kotx 191153 afdotx area forecast discussion national weather service spokane wa 353 am pst Mon nov 19 2018 Synopsis Dry and stable weather will continue through Tuesday. Look for areas of low clouds and fog in the columbia basin to expand into the east slopes of the cascades and lowlands of northeast washington by Tuesday. The weather pattern will become wet and unsettled starting Wednesday. Mountain snow may impact travel across the cascade passes through the holiday weekend. Discussion Today through Wednesday morning. No significant changes are expected today and Tuesday as the ridge of high pressure dominates the weather and slowly moves into the region. Even though the atmosphere remains very dry the boundary layer moisture has been slowly increasing the past 24 hours. The combination of increased low level moisture and the very strong inversion will result in a better chance for morning fog and stratus development today and Tuesday. Lower Sun angle will make it much harder to break down the inversion and allow much afternoon mixing. One last thing is a closed low is spinning off the southern ca coast. The resultant southerly steering flow will allow smoke from the california fires to advect into the area as early as this afternoon. So, what to expect? Areas that see fog and low clouds today will have a tough time totally clearing out, but could see a short window of blue sky late this afternoon, otherwise it will be another sunny day. The fog stratus will expand in area tonight through Tuesday morning, with the fog likely lifting into a low stratus deck Tuesday afternoon, then conditions will deteriorate again Tuesday night. Winds will remain light out of the northeast with temperatures near seasonal norms. Wednesday... Wednesday and out the rest of the week the weather will become wet and unsettled as a series of weather systems move through the region. The first is expected Wednesday afternoon Wednesday night. This wave will weaken as it breaks down the ridge, but it will allow the first shot of deeper moisture to move into the region off the pacific. Isentropic up glide doesn't move across the cascades until around mid-day Wednesday or later, then slowly moves through the inland northwest late in the afternoon and overnight. So we are expecting a chance of light precipitation near the east slopes of the cascades, possibly making it to the columbia river by sunset. Precipitation through sunset will be very light, maybe a couple of hundredths near the crest. Snow levels will make this as snow down to pass level and the crest may see around an inch of snow by sunset. Tobin Wednesday night through Sunday: by this time interval ridge axis placement over eastern montana provides an open door along the western edge of the ridge for weather disturbances to enter the pacific northwest. One such system continuing its eastward movement Wednesday night has a well established tap into moisture entering from the south, and having such an orientation would help to mitigate any rain-shadowing effects on the lee side of the cascade crest, but at the same time a number of older model runs have hinted that this system has some potential to split elongate weaken substantially as it moves through Wednesday and with this in mind the QPF and snow amounts associated with its passage are low and pops are not ramped up too high except for perhaps the more orographically favored areas Wednesday night into Thursday. A more powerful low pressure system that has an intensifying and deepening

surface low progged to pass in a nearly west to east trajectory close to the british columbia border is a critical weather pattern worthy of robust and gusty winds Thursday night into Friday in addition to the higher pops and QPF Thursday night ahead of the increased winds. Brief interval where the jet stream is nearly overhead of the southern portion of the forecast area allows for a cold conditionally unstable airmass to linger over the northern portion of the forecast area Friday which would suggest holding onto more orographically looking pops for showers coupled with a dip in snow levels but by Friday night weak low amplitude ridging cluttered with disturbances and moisture fluxing through it maintains influence over the forecast area. Current models suggest there is potential for more wet frontal zones with somewhat warm southwest to northeast trajectories of approach and exit to move through the region over the weekend so an unsettled forecast remains with somewhat low confidence in the timing of when such disturbances move through. With such a dynamic weather pattern in place forecast temperatures are generally expected to be on the warm side of what would be normal for this time of year, especially so during the gusty breezy Thursday night Friday portion of the forecast. Pelatti Aviation 12z tafs: high pressure and dry conditons remain over the area this morning. However near the surface relative humidity is up 5-15 percent over 24 hours ago. The development and timing of fog and low clouds will be the forecast challenge this morning. Satellite and camera observations indicate that there is fog along the snake river, it just hasn't gotten up to the airport yet and ifr lifr CIGS vsby were pushed back until 15z. There is fog along the lower snake and columbia rivers from kalw kpsc khms, but there is is little confidence that this fog will make it into keat or kmwh, but some lower vsby was added to kmwh around sunrise. Fog stratus has also developed for the northern lakes including lake coeur d'alene and along the spokane-columbia rivers. The kcoe ksff will have the best chance for MVFR ifr conditons 14z-18z with conditions improving through the afternoon. Kgeg kpuw should remainVFR through 12z Tuesday.
