954 FXUS66 KOTX 141752 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 1052 AM PDT Sat Jun 14 2025 .KEY MESSAGES... - Mainly dry with gradual warming trend through Monday. - Gusty winds Monday into Tuesday with cold front passage. && .SYNOPSIS... Lighter winds and mild temperatures are expected for the weekend. Isolated showers and thunderstorms are possible along the Canadian Border today. Warmer temperatures will occur on Sunday and Monday before an increasing risk for elevated fire weather conditions from gusty winds for the middle of next week. && .DISCUSSION... Today through Tuesday: Models continue to show a large closed low off the central and northern BC coast resulting in a prevailing west to southwest flow through the period. Limited moisture will result in a mainly dry forecast with a few exceptions. First is today over the northern mountains where surface heating will help generate some afternoon convection. Uncapped CAPE of 200-400 J/KG will also lead to a 20% chance of thunderstorms, primarily over the mountainous terrain near the Canadian border. Second is on Monday when a mid level wave combines with afternoon heating to potentially trigger isolated convection near the Canadian border, and areas around the Blue Mountains and Camas Prairie. Right now the NBM has low POP`s of 5-10% but pattern recognition suggests some potential for shower and isolated thunderstorm development so this will continue to be monitored. The decreasing PWAT`s the next few days will help promote more sunshine, and lead to a warming trend this weekend. Wednesday through Friday: Ensembles are advertising a change in the pattern for the middle to end of next week as that large low begins to track towards the region. A leading short wave on Wednesday has limited moisture, but will bring breezy conditions. On Thursday and Friday with the low continuing to approach a cooling trend occurs, along with an increase chance for rain showers.
