Temperatures will continue to run above the average for this time of the year. Typical high temperature for Grand Junction is 91° – Montrose is 88°.
There will be another late afternoon opportunity for storms to pop off the higher elevations and move over the populated lower valleys. Mountain storms will develop again during the midday and as early as 3 pm could move off the Roan/Tavaputs, by 4-5 pm off the Uncompahgre for Montrose and by 7 pm for Grand Junction. These storms should not survive much past sunset tonight (8:45 approximate/location dependent). Brief downpours, lightning and gusty wind speeds are the associated hazards.
As we head into the weekend, the next weather maker will be the advancing cut off low pressure system from the southwest. This will allow another late afternoon storm shot for the Western Slope. Temperatures will still run hotter than the normal for many, close to the norm for a few. The afternoon storms notwithstanding, the weekend looks pretty good.
Another storm system will be developing out of the Pacific Northwest for the start of next week. In response, the wind speeds are expected to increase Sunday and Monday- possible Red Flag Warnings. The extended forecast indicates less hot temperatures for the middle of next week.
Mesa County has a rain deficit (as recorded at the Grand Junction Regional Airport) of 1.45″. Normal rain totals for this time of the year need to be 4.22″, historically. Remember even if we are NOT under a Red Flag Warning, very dry conditions remain in place and any wind speed can quickly spread a flame or ignition source.
