A Hot Stretch, But Cooler Weather Is Coming

The past month has been quite warm and enjoyable in northern Utah.  If you are wondering where it ranks historically, the answer is quite high.  If we look at the past month (i.e., since September 13), it ranks as the 2nd warmest in the instrumented record.

You might recall that in mid September we had a stretch of cooler, rainier weather.  If we chop off that period and look a the stretch from September 20 to October 13 (yesterday), it is the warmest such stretch in the instrumented record.

There are, however, some changes coming.  First, we have a short-wave trough moving in from the southwest on Friday night.  Then we have a another shortwave trough approaching from the west later in the weekend.  Together, these two systems will bring cooler weather and some showers and thunderstorms to northern Utah this weekend.  There probably will be some snow on the high peaks late in the weekend, but unless the one of the outlier ensemble members verify, snow lovers will probably need to wait a bit longer for a major dump.
