Excessive Heat Warning continues for portions of Mesa and Montrose counties.
The third day of 100 of a degree reading has occurred and another new temperature record is in the book for Grand Junction! The old record was 100F from 1946 and as of this writing, Grand Junction was at 102F. These hot temperatures (average this time of the year for GJ is 89/90) will continue into the upcoming weekend. Records are expected to tie or topple for a few more days as well. The peak heating will be achieved during the midweek and a run for Grand Junction’s all time high temperature is still possible (106F 2005). The only relief might come in the form of added cloud coverage during the late afternoon hours from the midweek on.
Partly cloudy afternoons are in the forecast, but this pattern will be minimal defense against the ongoing heat wave. The clouds could offer a degree or two of less heating when all is said and done. The mountain zones will be firing off rounds of late day storms and from these isolated cells with little movement, gusty winds and lightning will be the primary hazards. The very dry conditions in place will not bode well for fire weather and natural fire starts are anticipated from the High Country storms. Red Flag Warnings are possible later this week as a result.
