Monsoon keeps good chance of thundesrtorms in the forecast through Friday

SUMMIT COUNTY — It looks like enough monsoon moisture will continue streaming into the high country out of the south to keep a good chance for afternoon thunderstorms in the forecast through Friday. Then the flow will shift more to the west, with drier air moving into the region for the weekend. Saturday and Sunday only show a 20 percent chance of showers.

Under cloudy, wet skies, highs will only climb into the mid-60s the next couple of days, then warm up into the upper 60s and 70s for the weekend. Wednesday’s high in Frisco only reached 57 degrees, well off the record, 82 degrees, set in 1953. Overall for the month, many of the record daily high temperatures have been set since 1990, supporting evidence for the human-caused global warming trend off the past few decades. Read more about the trend toward more and more record highs here. The exception was a 1939 heat wave, when Frisco temperatures climbed into the high 80s every day from June 8 through June 16.

For the next few days, the National Weather Service says precipitable water values in the atmosphere over the high country will climb to almost an inch. With daytime heating, that could mean some heavy rain for the area.

By 8 p.m. Thursday, temperatures had dropped to the low 40s at some of the mountain stations, including 42 degrees at Hoosier Pass and 41 degrees at Loveland Pass. Check this link for the readings from the automated weather stations around the area.

The high readings for Wednesday across the state were 93 degrees in Grand Junction, and 89 degrees at Rifle and Cortez. A few locations dropped into the 30s, including Monarch Pass and Gunnison.

The nation’s hotspot once again was Death Valley at 116 degrees, while Pahaska, Wyoming dropped down to 27 degrees.
