Widespread overdevelopment by 1 pm. First the backside of Inspo went off, then Evanston, and then Strawberry. After that, each cell closed in on the Wasatch front and Jupiter.
There was no escape and a task was clearly impossible to call.
The awards were given out shortly after back at HQ and the comp ended on a good note overall, with 4 solid days of flying in somewhat atypical conditions for the area.
More closing thoughts on the next post.

Weather outlook for Sept 10
The general weather outlook for September 10th around SLC.
Second , the NWS synopsis:
Let's dissect this below.
Current Surface Winds
Canyon drainage flow is present, but not as widespread as yesterday. The flows will still top 30mph this morning and back off just as they have by early afternoon.
Winds 12 PM
Lift Potential & Clouds
High and some mid level clouds will continue to spread across the region. Sunny in the morning, then partly cloudy later in the day. Cloud base around 13k with top of lift the same. Valleys to the east for SLC will see top of lift and cloud base around 14-16k. Will deep convection lined up for later today, height of base will dance around a bit.
Over Development & Precip
NWS states 30% chance of TS, which translates to nearly a 100% certainty we'll see large TS in the area. Most storms will be accompanied with rain and strong gusty winds later in the day.

First, a word from your sponsor: thanks for supporting XC Skies. Without your contributions, ideas, and enthusiasm to create a better and more useful tool for our pilot community, this project would have collapsed in on itself the first season.
Second , the NWS synopsis:
Area forecast discussionToday is a tough love kind of day. We're trapped in a deep moisture surge with the low to our SW stalled out a bit today. This will allow more moisture to pump into the region instead of cutting off the firehose from the south. N Utah is expected to see more precip events and strong TS starting early afternoon. The Uintas will likely overdevelop first, and with the east winds overhead, these storms will drift into the SLC valleys.

nearly stationary through the weekend. A resultant southerly flow
