Today's weather setup is one that favors some showers and thunderstorms, but not necessarily in widespread fashion.
The set up includes high pressure over us and low pressure with an abundance of deep atmospheric moisture to our west. The high pressure will be squeezed to our east over Kansas today as that disturbance to our west moves toward us. The showers and thunderstorms will begin over the mountains, and over the mountains is where the wet weather will be most abundant. Some of the storms will move out of the mountains and toward the I-25 corridor. High elevations, such as northern El Paso County, will be most favored for rain east of the mountains, though they could persist in other locations, too. The atmosphere's moisture content will increase more rapidly over the Plains, so storms that do hold on east of I-25 could bring some hefty amounts of rain in a short period of time.
Expect high temperatures today in the 80's and 90's with 70's in high elevations. We will warm through the 60's and into the 70's by 10 AM with sunshine and just a few clouds. StormCast hints at a few mountain showers beginning to form as temperatures warm into the upper 70's and lower 80's with lower 70's in high elevations. At 2 PM temperatures are warming into the 80's, and there are some showers that generally stay in the mountains. Even there the showers are mainly isolated in nature. Through 5 PM, with 80's and 90's, we're seeing only isolated showers moving off of the mountains. Expect the breeze to increase a bit this afternoon in the 10-20 mph range.
Tomorrow that disturbance from the west will move across the top of us. Showers and thunderstorms will become more widespread in response and temperatures will be 2-5 degrees cooler. A dry period sets up Wednesday through Friday as high pressure squeezes back to the south and sets up a west-to-east wind that will be enhanced by the lee trough east of the mountains and decrease the atmosphere's moisture content. Temperatures will respond by warming, and only an isolated pop-up storm will be possible. Then on Saturday and Sunday humidity will increase again and help to boost the coverage of showers and thunderstorms again. Higher humidity will mean cooler days, but the muggy factor will also increase.
