  (on/off)  Help NOTE: mouseover dotted underlined text for definitionFxus66 kotx 221218 afdotx area forecast discussion national weather service spokane wa 418 am pst Fri feb 22 2019 Synopsis Another round of light to moderate snow will spread over northeast washington and the idaho panhandle on this afternoon and into this evening. A moist frontal system is expected to stall over oregon and central idaho Sunday and Monday and will have the potential to produce moderate to heavy snow as far north as the camas prairie. No big warm up is expected in the next seven to ten days with much below average temperatures through next week. Discussion Today and Saturday: fog is expected to impact the columbia basin this morning with some areas reaching a quarter mile vis. As the next system begins to push into the region, the fog is expected to lessen across the region late Friday afternoon. The models are tracking the next system with good agreement from the previous runs and each other. It is expected to move pretty quick and bring periods of moderate snow. Amounts have stayed around the same as the previous forecast. Areas in the columbia basin and lower elevations can expect up to 1 to 2 inches of new snow. The heaviest amounts are expected in the cascades with amounts near 6 to 10 inches. The idaho panhandle mountains can expect amounts int the range of 3 to 6 inches. By late Saturday afternoon, a few lingering snow showers in the mountains will remain. Winds will slightly increase ahead of the system with gusts near 20 from the northeast. Cloud cover will help keep the temps a little warmer overnight than the previous nights. The highs will in the 20s and lows in the teens for most. Jdc Sunday through Thursday: continued positioning of a narrow ridge of high pressure off the coast keeps a cold northerly flow over eastern washington and north idaho through the interval hence below normal temperatures are expected to remain. Some operational models suggest some changes to the weather pattern may include the appearance of a quasi-stationary wet frontal feature coupled with a deepening and intensifying area of low pressure off the coast over the coast developing in the early portion of the week, potentially having this frontal feature pivot around the offshore low and move northward as a wet warm front and bring |
snow to the far southeast portion of washington and portions of the north idaho panhandle Monday before pulling away and exiting to the southeast. Further complicating the meteorological setup is the appearance of cold conditionally unstable air with the more intense surges of northeast flow that along with increased northerly northeasterly winds at the surface could bring about higher intensity localized snow shower activity with the highest pops over the more orographically favored areas over the far southeast portion of washington and southern portions of the north idaho panhandle along with what looks to possibly be more stable airmass associated with a weakly defined col or saddle point over the region potentially in the Tuesday night Thursday time frame suggesting even lower pops while the higher pops remain focused within close proximity over oregon. Pelatti Aviation 12z tafs: . Freezing fog is impacting at kgeg and puw. This moisture is expected to eventually push into keat by mid morning. Easterly winds is expected to result in improving conditions at klws and kpuw by early afternoon. A weather system will increase snow chances Friday afternoon with moderate snow possible across the spokane coeur d'alene corridor by the evening hours. By early Saturday am, low stratus deck and patchy fog can lead to ifr conditions for TAF locations as the snow system pushes out of the region.
