Friday, September 6:

Usually we try to update a little more often as we enter September, but a lack of anything interesting to talk about has kept the new posts relatively infrequent. Looks like Utah will have a continued slight chance for afternoon thunderstorms each day this weekend. A cold front will help cool temps a bit on Sunday and Monday. No imminent signs of Winter-like storms yet.

Currently there is a Low pressure system moving into Washington state. This will gradually lift northeast through the weekend and will drag a ‘cold’ front through the area on Sunday while the main circulation passes well to our north. At the very best, we’ll see some breezes, a few more clouds, and maybe a thunderstorm or two. It will also cool record temperatures from yesterday down closer to average on Sunday and Monday (mid-80s in SLC).

Next week we see major ridging again with the ridge axis almost directly over Utah. This will warm us back up above normal. It will also open the door for another monsoonal moisture surge. We are getting toward the end of the monsoon season, so this could be our last major surge of the year. It will serve to further enhance afternoon convection (thunderstorms) in Utah mid to late next week.

Beyond next week, the GFS has been hinting that we could see a few weak storms and cooler temperatures enter the area as we enter the second half of September. The Euro tries to cut-off another low off the Pacific coast similar to the one currently out there. Without too much consensus, it’s hard to say how the second half of the month will look. With summer-like weather looking like it will extend deep into the meteorological Autumn, my guess is that when the pattern finally breaks, it’s going to be a rude welcome to the new season, which could mean our first snow in the higher elevations. Until then, we’ll just have to wait and see.

Speaking of Summer, the Wasatch Front just experienced its hottest Summer ever, and it wasn’t even close! As you may recall, July was the hottest month ever recorded in SLC. August followed suit by becoming the hottest August ever in SLC. Together with a warm June, we had the hottest June-August (meteorological Summer) ever. Luckily, it wasn’t totally dry with consistent monsoonal surges to dampen vegetation and reduce fire danger. Our previous hottest summer, 2007, turned into a great snow year with close to 800″ at Alta. Let’s hope we see the same!
