A flattened ridge draped across the CWA will continue to transport weak moisture across the region during the early part of next week. This will likely just result in cloud coveron Monday with a few isolated orographic showers possible over the mountains. Upper level winds will continue to mix down to the surface on Monday with gusts 25-30 mph expected again Mondayafternoon. The ridge axis slides overhead by Tuesday afternoon, with  an embedded shortwave or two rippling through, increasing chances for more mountain showers during the afternoon. Winds aloft are slightly less on Tuesday, but some mixing will still find us in the breezy afternoon pattern weve come to expect this spring. Temperatures will also inch upward through midweek under the influence of the overhead ridge. Through Wednesday, some of our desert valleys and lower elevations of southeast Utah and southwest Colorado will see 80+ degree afternoon highs enter the picture again. Temperatures will trend 10-15 degrees above climatology during this warmup. Height falls Wednesday see the return of a stronger southwesterly jet streak out in front of a low digging down the West Coast. This will drive up winds and usher in, yet more, dry and warm air Wednesday afternoon ahead of the approaching trough. The trough swings through on Thursday and delivers another round of scattered showers to the mountains. Moisture still looks pretty meager at this point and will likely just yield clouds and maybe trace amounts of  rain to the dry valleys, whereas the mountains could see a few wetting showers in spots Thursday afternoon. A brief transitory ridge between waves passes Thursday night before another push of unsettled conditions Friday afternoon and Saturday. This should lead to another round of gusty southwest winds ahead of the next frontal boundary. Late week temperatures will trend downward toward climatology thanks to precipitation and cloud cover.
