627 FXUS66 KOTX 241813 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 1113 AM PDT Mon Jun 24 2024 .SYNOPSIS... Expect mild and dry weather today followed by heat for Tuesday. A cold front arrives Wednesday with wind and storms that lasts into Thursday. Then the cycle repeats. More mild and drier weather is likely for Friday followed by heat Saturday and then more wind and storms for Sunday. && .DISCUSSION... Today through Tuesday: Brisk westerly flow aloft will be over the Inland NW today with bands of high clouds. It will be a quieter dry day with lighter westerly winds. Temperatures should be noticeably cooler or more seasonal for late June with highs in the mid 70s to mid 80s. By tonight into Tuesday, the flow aloft rebounds into a shortwave ridge. Low level winds back to the south and east as while temperatures are expected to jump 6 to 10 degrees warmer. With daytime highs in the 80s to mid 90s on Tuesday, elevated heatrisk will be found across the Columbia Basin and the LC Valley./rfox. Wednesday through Sunday: Frontal zones pivoting ahead of an upper level area of low pressure sagging down from the northwest will bring showery weather, including some thunderstorms Wednesday along with gusty/breezy winds. The cold upper area of low pressure will park within close proximity, if not directly overhead, Thursday and the resulting iinstability will allow for unsettled weather in the form of mostly afternoon and evening showers and thunderstorms along with gusty/breezy conditions. The upper level low moves east and is replaced with a cool and somewhat unstable northwest flow Friday which allows for some showers to linger with less intensity and persistence, and mainly near the British Columbia Border and allows the cooling trend to bottom out. Shortwave ridging and associated warmer southwest flow allows for a warming trend with a generally dry Saturday, however the southwest flow eventually allows for increasing potential for moisture and disturbances to approach from the west that segues to a general trof moving through Sunday which allows for a return to potentially more showery and unsettled conditions along with breezy/gusty winds. /Pelatti && .AVIATION... 18z TAFS: VFR conditions expected for the TAF sites for the next 24 hours. Scattered high clouds will be found across the region. West to southwest winds will prevail through midday and then lighter terrain driven winds continue for rest of the period with speeds less than 10kts. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence in VFR conditions through the TAF period. /JDC ----------------------- Confidence descriptors: Low - Less than a 30 percent chance Moderate - 30 to 70 percent chance High - Greater than a 70 percent chance For additional probabilistic information for NWS Spokane airports, please refer to the Aviation Dashboard on our webpage: https:/www.weather.gov/otx/avndashboard && .PRELIMINARY POINT TEMPS/POPS...
