Monday August 23, 2021 Forecast First


High temperatures are going to be running slightly hotter than the averages this time of the year for the first half of this week. The average high for Grand Junction is 90 degrees and for Montrose it is 86 degrees. This late August heat will get an interruption on Thursday with widespread showers and thunderstorms and associated cloud coverage keeping things cooler, but just for the day. Mark your rain journals for late Wednesday and most of Thursday as our next shot for measurable rain on the Western Slope. After that, there will be more warmth, drier conditions and likely a decent breeze.

Wind speeds will be picking up this week in response to the next weather maker, a low pressure system, advancing in from the Pacific NW/across the Western U.S. in the next few days. Red Flag Warnings are in place for the NW corner of Colorado for Tuesday and (likely) Wednesday. All areas will go breezy Tuesday and Wednesday and once again this weekend (on the backside of our exiting low). Measurable rain looks good for Thursday. The mountains will actually keep late day storms popping through the entire extended forecast (before and after Thursday) while the lower elevations should remain dry and hot.
