Area Forecast Discussion National Weather Service Pendleton OR 629 PM PDT Mon Sep 27 2021

SHORT TERM. The latest ir satl was showing a large area of light to moderate pcpn over north central Oregon and south central WA with locally moderate to heavy pcpn along the foothills of the blue mountains. Further west along the wa/or cascades the pcpn area lessens. Meanwhile the entire area can expect showers to persist overnight especially in the eastern sections of the region and the forecast was updated to increase pops along the foothills of the blue mountains and eastward tonight.

Otherwise minor changes were also performed on pops and sky and pcpn amounts and the present short term forecast appears on track for tonight.

PREV DISCUSSION. /issued 455 PM PDT Mon Sep 27 2021/

SHORT TERM . Tonight through Wednesday . Satellite and radar imagery this afternoon is showing a cold front slowly moving across the PacNW with showers developing across the eastern half of the forecast area. Meanwhile surface observations are indicating that the frontal boundary at the surface has moved across the central OR and the OR/WA Columbia Basin. An upper level jet that is parallel to the frontal boundary will continue to slow the system this afternoon. Behind the surface frontal boundary, a wide rain band will slowly move across the forecast area into this evening, providing a chance of rain across most of the forecast area. Breezy westerly winds will also persist into this evening across those areas that have seen the frontal boundary come through. Behind the rain band, precipitation chances will begin to trail off across the Columbia Basin and adjacent valleys, while the Cascades and eastern mountains will continue to see rain and possibly snow impacts well into tomorrow. Snow levels will begin to drop to about 5,500 feet across the forecast area tonight, as a cold airmass infiltrates into the region behind the frontal passage.

Following closely behind the cold front, an upper level trough will move across the forecast area starting early tomorrow. This will help sustain precipitation chances across the mountains and foothill locations, however the Basin and adjacent valleys, as well as portions of central OR will likely remain dry tomorrow. Breezy westerly winds will redevelop across the Basin and north central OR tomorrow afternoon as the upper trough axis passes overhead. Behind the trough axis passage late tomorrow afternoon, precipitation chances in the mountains and the breezy westerly winds will begin to diminish, becoming dry and calm by midnight.

Wednesday, a ridge of high pressure will build into the region from the northern CA, providing mostly dry and calm conditions across the forecast area. However, by Wednesday afternoon, a shortwave trough swinging into central BC will provide increasing cloud cover from the west and a chance of rain showers across the WA Cascades that will spill over into portions of the WA east slopes.

Temperatures behind the frontal passage starting tonight will become below normal as a colder airmass advects into the intermountain northwest. Afternoon highs tomorrow will mostly be in the upper 50s to 60s, though in the mid 40s to mid 50s in the mountains. Overnight lows Wednesday morning are expected to be the coldest for the week, with 30s to low 40s expected across much of the forecast area. Wednesday, afternoon highs will continue to be below normal, with temperatures mainly in the 60s, and 50s in the mountains. Lawhorn/82

LONG TERM . Thursday through Monday . Another upper-level low is forecasted to pass over the CWA on Thursday. Guidance in good agreement on depicting this system, however QPF ensembles not producing much east of the Cascades. EPS a bit wetter than GEFS, however wouldn't be surprised, given the system's northeastward trajectory, if the lower Basin and central OR stay mostly dry through the progression of this low. In the WA Cascade crests, ensembles range between a half inch to an inch of precip, with very little if any rain over the OR Cascades. Even most of the Blues outside the northern portion along SE WA look to see only isolated light showers at best. Overall, sensible weather impacts look to be pretty limited with this system.

Beyond Thursday, the majority of the long term looks to be quiet as ridging builds overhead behind the exiting low. Ensembles differ on the position of the ridge's axis and the timing of its amplification, but overall pattern looks to keep us dry with warmer than normal high temperatures. Weekend highs will depend heavily on how the ridge develops, but looking at low to mid 70s across much of the forecast area to start off October. A few ensemble members depict a weak cutoff low offshore over the weekend, which may inject some Pacific moisture aloft and impact temps, but looks to be weak enough to avoid any significant impacts on the forecast. 74

AVIATION . showers will persist at all taf sites into Tuesday. Some of the taf sites such as krdm and kbdn could approach lcl mvfr conditions in heavier showers until 06z . while most others should remain at mainly vfr conditions throughout the period.
