PREV DISCUSSION... /issued 233 PM PDT Wed Jun 19 2024/

Tonight through Friday
As mentioned in the morning forecast update discussion, some shallow instability from the weak upper level trough over the region has lead to some showers developing over the eastern mountains this afternoon. These showers will continue into the evening then dissipate towards sunset. The shallow nature of the convection means lightning is unlikely but would not rule out some random strikes. Otherwise, skies remain mostly clear across the rest of the forecast area today with warmer temperatures boosting high temperatures into the 80s around the Columbia Basin and 70s in the mountains and light winds.

Conditions will be very similar Thursday with the weak lingering trough over the region and its associated instability. For now the chance of showers over the eastern mountains is less than 10% so no mention of showers at this time but this could change with subsequent forecast updates. By Friday the weak trough finally exits to the east and a flat ridge of high pressure moves over the area.
This will allow temperatures to continue to increase another 3 to 6 degrees on Thursday and 2 to 5 on Friday. This will bring high temperatures in the Columbia Basin to the upper 80s to mid 90s on Friday and 80s in the mountains. Winds will remain light overall with an afternoon north to northeast in the afternoon producing winds of 5 to 10 mph Thursday and Friday.

Saturday through Wednesday
A upper level ridge will remain over the region Saturday until exiting eastward Sunday when the zonal pattern arrives through Monday. Then, a weak ridge will build over the PacNW late Monday into Wednesday. Dry, warm conditions continues for the extended period with no chances of precip. High temperatures for Saturday will remain above normal in the 80s and 90s for the forecast area. Sunday through midweek, temperatures cool down by few degrees as westerly flow increases with the arrival of the weak upper trough driven by a closed low off British Columbia.

High chances (>70%) for breezy conditions with wind gusts at 20-30 mph beginning late Saturday along the east slopes of the Cascades then spreading across the Columbia Basin Sunday. Sunday windy conditions could occur for Blue Mountain Foothills, Columbia River Gorge and the Kittitas Valley with wind gusts exceeding to 40-45 mph (60-80% probability). With increased winds and dry conditions, this will elevate concerns for increased fire weather through Sunday around Columbia Basin. Otherwise, winds will then decrease late Sunday night but breezy winds continue across the forecast area with wind gusts at around 15-25 mph through Wednesday (40-50% probability). Feaster/97
