This week has featured yet another monsoonal moisture surge. Yesterday was positively Cascadia-esque along the Wasatch Front with low-hanging clouds throughout the day with occasional showers. All the cloud cover actually inhibited afternoon thunderstorm development because we lacked sufficient surface heating to destabilize the atmosphere. Still, most areas saw rain in the morning and another band of showers move through overnight last night. Temperatures also remained cool in the 70s most of the day in SLC. Today we may see a bit more breaks in the clouds which may help us to destabilize things this afternoon and get some more showers/t-storms into the area before we start to dry out a bit tomorrow.
The real exciting news is that models have latched on to an interesting system for this weekend. If you read the post a few days ago, I mentioned that models had been toying with the idea of a cool, Fall-like trough dropping into the Northern Rockies. Models have continued this trend and have actually deepened the trough so that it looks like it will at least clip northern Utah. This system is coming out of the northwest and is fairly typical of September/October, but we rarely see this type of system in August. It’s not going to be cold enough for snow in the mountains, but cool showers up high with temps in the 40s is likely with valley temps dropping back into the 70s on Saturday and Sunday.
I know everybody is itching for snow to be in the forecast, but this is the first step in the long road back to winter. It’ll be nice to have the cooler temps for my recreation purposes this weekend as well.
