Showers and thunderstorms will be slim in coverage again today, and temperatures will be unseasonably warm again.
The atmosphere aloft is quite dry, but at the ground the humiditt is high enough that you will feel it doay. It is also high enough to indicate sufficient moisture for a pop-up thunderstorm or two. Those few storms that do develop will likely be pinned to the mountains, though or two may run out of the mountains to the I-25 corridor. Where those dew points are highest - along the Kansas border - moisture is sufficient to support some late afternoon and early evening thunderstorms.
The morning is quiet and will stay that way. Warm high pressure is the main feature affecting our weather. That high pressure will squeeze back to the west enough to generate a wind flow from the north late this afternoon. The upslope component to the wind up the north-facing side of the Palmer Divide may aid in thunderstorm development. Even still, any showers or thunderstorms will be isolated in nature and most areas will remain dry aside from that stray storm.
Our day will be marked by quickly warming temperatures beneath sunshine and high-altitude clouds. By 10 AM, 80's already blanket the map, though 70's will linger in high elevations like Monument and Woodland Park. Noon shows a mix of 80's and 90's, with 90's primarily along and south of the Arkansas Valley. 2 PM temperatures are nearing 100 along the Arkansas Valley with 80's and 90's north and south of the river. We will continue to simmer through 5 PM, and an isolated thunderstorm or two will help to tame the heat 2 PM through 5 PM for the few spots that actually do see any rain.
The weather pattern changes little through Wednesday, favoring unseasonably warm temperatures and only isolated thunderstorms in the late afternoons. The return of the well-pronounced afternoon upslope breeze is on Thursday. Given available moisture, showers and thunderstorms will return to the forecast, and temperatures will trend down starting Thursday and continue into the weekend.
