We have one more day of unsettled weather today and then the big warmup begins.
By Tuesday, a high-amplitude ridge will be parked right over Utah. The weather should be splendid and the Bonneville Shoreline Trail packed with mountain bikers.
Although the ridge is parked over us in Tuesday, right now Wednesday looks like it may be the warmer afternoon. The latest GFS suggests that on Wednesday as the ridge weakens, a weak surface trough approaches from the north and northwest.
This typically results in enhanced southerly flow and, with 700-mb temperatures near +6ºC, maximum temperatures on Wedensday afternoon may reach the upper 70s at the Salt Lake Airport (the highest maximum we've had so far this year was 75ºF on March 25th).
The way things have been going so far this spring, maybe we'll hit 80 at the airport, where once again the temperatures appear "jacked." In other words, they seem to be a couple degrees warmer than I would expect, and also higher than I would anticipate from observations from surrounding sites. This is something that we discussed last summer (see What's Up @ KSLC) and remains inadequately resolved. Perhaps we will try to revisit this issue in the coming days or weeks.
