Update 6:00pm: Right on time, showers and thunderstorms developed this afternoon. Expect showers and thunderstorms chances to come to an end by 6:30pm/7:00pm in Colorado Springs and 8:30pm/9:00pm in Pueblo.
Rest of the forecast looks on track. - Meteorologist John Dissauer
Update 9:12am: Beautiful start to Sunday. Clear skies and temperatures got down in to the 50's and 60's.
With sunny skies this morning, temperatures should quickly rise. Expect high temperatures to be in the middle 80's to middle 90's. Very similar to Saturday.
Some upper-level energy is moving southeast out of Canada this morning. A piece of the energy is expected to clip Colorado this afternoon. This may help a few showers and thunderstorms develop this afternoon. Here are the best times for any rain today...
We are looking at 20%-25% chance for a shower or thunderstorm in El Paso and Teller counties. About a 15% chance for a passing shower around Canon City. IF a shower and/or thunderstorm can hold together and move in to Pueblo County, the best time for rain in Pueblo will be between 5pm and 8pm. However, I am looking at less than a 15% chance for rain in Pueblo today.
TOUCH OF FALL
It is still several days away but there are hints we may tap in to cooler Canadian, for the first time in several months, this weekend.
One of several long-range computer models has been suggsting cooler air arriving around this time period for several days. The model is published by the European forecast agency. It is a model I have put a lot of weight behind for all of the 17 years I have been forecasting the weather.
Last night's run suggests that a cold front will sweep through Colorado Friday. Ahead of the front, temperatures would likely surge in to the upper 80's and upper 90's to near 100°. Once the front passes, cooler air will begin to ooze in to the region for Saturday and Sunday. How much cooler? At this early stage, it looks like highs in the 60s and 70's with lows in the 40's and 50's.
As I said, it is still early and a lot can, and lkely will, change over the coming days. And to be transparent, another one of the long-range computer models I look at, NOAA's Global Forecast model, suggests the cooler air holds off a couple more days. - Meteorologist John Dissauer
