Driving back from a quick hike up the 'bird early this afternoon, a well-defined shaft of precipitation was moving across the northwest Salt Lake Valley.
Radar imagery showed some very localized and isolated cells around that time over the Salt Lake Valley and the Oquirrh Mountains.
Sometimes when it comes to convection, it's better to be lucky than good. Of course, that assumes the storms didn't rain (and hail) on your parade. For me, I was glad we got the "shaft" as it cooled things down at my place, even though we only got a trace of rain.
Models are suggesting some sort of a trough/frontal passage tomorrow. The forecast high from the NWS for Tuesday is 82, which would be the lowest maximum we've seen around here since, gasp, June 17 (when it hit 82). For lower than 82, you have to go back a few more days to June 14.
