monsoon observations from Mountain Weather Masters forecaster Joe Ramey

This summer sucks… the energy out of many of us with this prolonged drought and heat. Today, Thursday, may be the warmest day of the year so far. We are expecting 103-105 here in Grand Junction today.
The monsoon oozed in from the south over the last few weeks. It has brought some heavy showers as far north as the San Juans. Most sites to our south have struggled with below normal rainfall too.
The rest of western Colorado keeps waiting for the rains, and there is a chance this weekend. The subtropical High is currently centered over the southern Great Basin but will shift east into the weekend. This will let the better moisture work up across most of Colorado. The High center returns after Monday next week which will again limit moisture to the Four Corners and points further south.
Otherwise no other surprising climate news. CPC’s new monthly and seasonal outlook shows a tilt towards hot and with an active monsoon. El Nino is still favored for the fall and early winter. El Ninos tend to produce above normal precipitation for the fall season and above normal winter snowfall for the San Juans.
Stay cool,
