A large area of high pressure in the mid-to-upper levels of the atmosphere remains centered just to our west, which is where it was late last week. It has held tight over the weekend, and beneath it moisture has been just enough that some isolated showers have formed. Those showers have been primarily in the mountains. Areas east of the mountains have seen little more than shallow fair-weather cumulus clouds. That high pressure will mean another overall dry and unseasonably warm day for us today, but the high is giving up some ground as a cold front passes across Colorado tonight.
Temperatures will warm quickly this morning under the bright sun. By 10 AM, we will be in the 80's with 70's in high elevations. By noon most areas are in the 90's with 90's and 100's at 2 PM. We will keep it hot through 5 PM, but we'll also see a few thunderstorms develop in the high elevations west of I-25. A few of those will be able to hold on and move out to the I-25 corridor. Storms will be more numerous today compared to yesterday, but even more storms are in the forecast starting tomorrow.
Humidity will increase behind the cold front that moves through Colorado tonight. That will up higher odds that you will see rain beginning tomorrow. Storms will begin in the mountains and ride the mid-to-upper level wind flow from west to east across the Plains in the late afternoons and evenings. The increase in moisture will help to bring a decrease in the warmth. Humidity and the overall upslope wind flow will help to bring about another round of storms Wednesday afternoon.
