Update, Monday 9/22:
Colder pacific storm looking likely to impact the area this weekend. Fall-like temps, rain showers and a bit of high elevation snow expected. Windy on Friday ahead of the system.
Isolated showers possible today. Break on Saturday before showers and storms return for Sunday and Monday. A more Fall-like system possible for late next week.
Our frontal boundary yesterday virtually stalled over far northwest Utah and southeast Idaho. By the time it finally moved into the Wasatch Front overnight, it had weakened significantly. Still, some metro areas saw stronger storms with plenty of lightning and thunder. You can see radar estimates for precip show were most of it fell to our northwest:
We will start to dry out today, but a few stray showers will be possible in the Wasatch and especially in the Uintas. Tomorrow should be a break day and the best day to get out and do something outside. A closed low will move through the region on Sunday bringing additional showers to the area. Showers should continue into Monday.
High pressure will be back for the middle part of next week but all eyes are on what looks to be our first Fall-like system since the end of August. A lot of uncertainty as both the EC and GFS have been waffling a bit, but right now it looks like the system will move in on Friday into Saturday. At the very least, we’ll see cooler temps in the area and a good chance for at least a dusting of snow in the high elevations. We’ll keep you updated!
