Hot & Dry Since June Worsening Drought Conditions; Maybe Some Weekend, Early Next Week or Late August Rain; La Nina to End Summer Start Fall
Jul 28th, 2021
The dome high-pressure that has been out west now extends over the Tri-state area through Friday with temperatures in the uppe. r 90’s and low 100’s, dewpoints in the 60’s mainly east of Highway 25 will put heat indexes at the 105-degree advisory levels. Over the weekend, the high-pressure ridge starts to weaken, and a trough develops over the Front Range, resulting in a return to more zonal and northwest flow over the local area. This will increase chances for some evening or overnight storms that have the potential to be slow movers with locally heavy rains. With many locations, especially north and west of a Colby and McCook line seeing abnormally dry conditions rapidly worsening and annual rain deficits of 6” to 7”, catching these rain chances is desperately needed.
