The fall season begins today (7:31 am MST). The temperatures are still running with a summer flavor, they are trending with above average warmth. There will be slight cooling from the previous days, a partly cloudy sky and a chance of afternoon showers and thunderstorms for the Western Slope.
The added cloud coverage, the increased humidity level and the sporadic late afternoon showers and storms (earlier for the High Country) will all be courtesy of the subtropical influence that remains in place. Southwest to northeast storm direction should put a few darker storm clouds over the valley locations through sunset Tuesday. Some lightning, gusty wind speeds and brief showers will be possible from the late afternoon through the early evening. Hard to pinpoint the exact placement of these storms, but given the pattern of a few rounds rolling through… there remains a slight chance of a brief/light shower for the populated tri-county areas. For the month, Grand Junction has received 1.13″ and Montrose has .56″ of rain.
The pattern is still rather mild after Tuesday and the area will continue to clear, warm (remain above the average 78°/76°) and dry. The first weekend of fall will have our next weather-maker. At this point it’s a rather dry looking cold front that will push through before the weekend is over. Ahead of it’s arrival we can expect strong wind speeds and in it’s wake… cooler temperatures.
