Area Forecast Discussion National Weather Service Pendleton OR 1007 AM PDT Tue Jun 23 2020 Updated aviation discussion .SHORT TERM...Today through Wednesday...A ridge of high pressure will be over the region ahead of a fast moving cold front and upper level trough that will arrive on Wednesday. High temperatures today will be in the 90s in the lower elevations and 80s in the mountains making it the hottest day of the year so far. High clouds will begin to increase overnight and and Wednesday with a cold frontal passage during the day. The front will be dry other than a few showers along the Washington Cascade crest and a slight chance of thunderstorms over the northeast Oregon mountains. Main impact will be some increasing westerly winds along the east slopes of then Cascades spilling out into the Columbia Basin. Temperatures will also cool 5 to 10 degrees Wednesday. .AVIATION...18Z TAFS...VFR conditions will prevail through the TAF period. Skies will mostly clear across all TAF sites with some increasing high clouds overnight. Winds will generally be less than 10 kts. && .PREV DISCUSSION... /issued 203 AM PDT Tue Jun 23 2020/ SHORT TERM...Today through Thursday night...High pressure aloft will persist for another day today with very warm to hot temperatures across the forecast area. Highs are expected to reach the mid 70s to mid 80s in the mountains and upper 80s to upper 90s in the lower elevations. Some locations will likely break 100 degrees, and some locations will see the first 90 degree day this season, such as the Pendleton Airport. On Wednesday a moisture lacking cold front will brush the forecast area and may bring showers over the mountains. There may also be afternoon thunderstorms over the northeast mountains. However with the lack of moisture and upper level support thunderstorms are expected to be non-severe, but there is a possibility that a storm or two may become strong with small hail and gusty winds. Moisture is lacking, so am not expecting much rain from storms on Wednesday. It will be a little cooler Wednesday due to increasing westerly winds and mixing as well as more cloud cover. Then high pressure will rebuild back over the region beginning on Thursday into the extended period with another warming trend. However, high temperatures will not be unusual for this time of year even though they will be above normal by about 10 to 15 degrees today. The threat of wind and low relative humidity may cause a fire weather concern for the Lower Columbia Basin and eastern Columbia River Gorge, but the threat is not significant at this time. Will still need to keep a close eye on conditions on Wednesday afternoon when winds increase for the lower elevations where the fine vegetation will be the most cured and dried from the hot and dry conditions expected during the next couple of days. 88 LONG TERM...Friday through Tuesday...Region will start out under an upper level ridge of high pressure Friday, leading to temperatures in the upper 80s to upper 90s outside of the mountains. The ridge will begin to break down Friday afternoon as a weak surface front crosses the forecast area and an upper level low pressure system begins to move south along the British Columbia coast, turning upper level flow westerly. Some light showers will develop with the passage of the weak front along the Cascades, continuing through Saturday under the westerly flow regime. Saturday evening, the upper level low will swing across the forecast area, where the center will position itself over the OR/ID/NV border through Monday. Isolated to scattered showers will develop both Sunday and Monday across the forecast area, with a slight chance of thunderstorms developing in the afternoon over the eastern mountains. Models begin to diverge on the progression of the upper low Tuesday, with the GFS showing the center of the upper low kicking east out of the region, while the ECWMF shows the upper low opening up into a trough over the western CONUS. Either solution, a slight chance of showers will continue over the mountains. Winds will be a concern Friday through Sunday as the surface pressure gradient tightens over the region in response to the colder upper level system, with breezy/gusty winds developing Friday and Saturday across portions of the Columbia Basin, in the Kittitas Valley and the Columbia Gorge. Daytime high will start off in the mid 70s to mid 80s Saturday, decreasing to unseasonably cooler highs in the upper 60s and 70s through Monday. Lawhorn/82 && .PRELIMINARY POINT TEMPS/POPS...
