Friday June 18, 2021 Forecast First


Excessive Heat Warnings have been cancelled early, but Red Flag Warnings are now posted through the weekend.

The cloud coverage did a number on a few areas as far as temperatures go. There is NOT a new temperature high record Friday afternoon for Grand Junction (because of the added clouds), but there IS a new record warmest low temperature for GJ that occurred Friday morning. 75F was recorded as the low besting the previous record from 1936 of 70F. Thursday night’s dying thunderstorms kept clouds around and warmth up above the norm (58F for GJ and 53F for Montrose are the average lows). Temperatures will be dipping slightly for Saturday and heating back on Sunday. More heat will return next week (the first week of summer).

Storms will be on the move from west to east Saturday after lunch and that should keep clouds building across the region Saturday afternoon and evening. Storms will have genesis sites in the mountains and should provide strong wind gusts and lightning strikes, but no rain for the lower elevations (officially). Rain will be present in the High Country along with some small hail, but the drought conditions continue along the exceptional category for the lower elevations. Red Flag Warnings are posted for Saturday afternoon along the entire Western Slope and into the western portions of the High Country. Lows Sunday will be mild as a result of Saturday’s storm clouds and dying t-storms.
