KEY MESSAGES
- Breezy winds will remain in place across far southwestern Utah around the Pine Valley Mountains, with peak winds expected to gust between 30-40 mph through Saturday morning.
- A stretch of dry and increasingly mild weather is anticipated over the weekend, with dry conditions expected to continue for a majority of this upcoming week.
DISCUSSION
An upper-level cutoff low digging southward into Arizona this evening will continue to bring gusty northerly winds to portions of southwestern Utah tonight. Main area of concern is around the Pine Valley mountains and through Black Ridge Canyon, where gusts 30-40 mph are expected through early Saturday morning. Otherwise, quiescent conditions remain in place across the remainder of the region.
Longwave ridging is expected to strengthen in the wake of this exiting low this weekend into next week, allowing dry conditions to continue with a gradual warming trend. As we're heading into the cool season, this persistent ridging resulting in warming temperatures aloft will be favorable for strengthening valley inversions, leading to some developing haze into next week. Ensembles still support a weak shortwave to graze northern Utah late Tuesday, though little impact is expected to the area outside of slight cooling mid-week and potential to mix out some of the haze building up across inverted valleys. Behind this wave, ridging redevelops across the west, amplifying in response to a deepening longwave trough off the west coast.
Long-range guidance does indicate a shift in the pattern by late next week as the aforementioned trough moves inland, favoring a cooler and wetter pattern across the west into next weekend.
