A warm and dry pattern will last into mid-week as a ridge of high pressure shifts inland over the region. Locally breezy winds will persist into Sunday across Central WA. The pattern shifts toward the end of the week and into next weekend as a trough ushers in cooler temperatures and a chance of showers. && .DISCUSSION... Sunday: Breezy north/northwesterly winds will linger into Sunday down the Okanogan Valley and across Central Washington as a ridge of high pressure nudges onshore, placing the region in a northerly flow pattern. The breezy winds combined with humidity values dropping into the teens Sunday afternoon will result in continued elevated fire weather conditions. Monday through Wednesday: The ridge axis continues to shift east over the region Monday through Wednesday, allowing temperatures to warm into the upper 80s to mid 90s by mid week. Late Tuesday into Wednesday, weak impulses rippling through the ridge will need to be monitored. The NBM continues to keep the forecast dry, but an isolated shower or thunderstorm isn't outside the realm of possibility as these disturbances move through an unstable atmosphere with steep lapse rates. Thursday through Saturday: Ensembles continue to hone in on a significant pattern change to close out the week with nearly 100% of model clusters now depicting an upper level trough dropping down into the region by next weekend. Differences remain on the timing and strength of this trough, but there is high confidence on a shift to a troughing pattern of some sort. Thursday will likely stay warm ahead of the trough with high temperatures only 3-5 degrees cooler than Wednesday. Heading into Friday, there is significant spread in the temperature forecast due to uncertainty surrounding the timing of the trough's arrival. By Saturday, most models show a nearly 20 degree drop in temperatures compared to the upper 80s to mid 90s forecast on Wednesday! The current temperature forecast for Saturday has highs ranging from the upper 60s to mid 70s. Gusty winds are inevitable with such a dramatic cooldown, so expect a windy day or two toward the end of the week. In addition to cooler temperatures and gusty winds, this system will also bring chances for showers and thunderstorms. Stay tuned for more info in the coming days! /Fewkes && .AVIATION... 06Z TAFs: VFR conditions expected through the TAF period.
