That break from the summer heat was nice while it lasted, but it's coming to an end today as temperatures climb quickly into the 80's and 90's again this afternoon. Today's warming is just a start. Some areas will warm back into the triple digits by the weekend. High pressure over Utah and Arizona will expand across Colorado starting today. It will intensify its hold over our area this weekend, though humidity beneath the hot high pressure area will be enough that isolated afternoon thunderstorms will be able to develop. The overall trend, however, calls for warming and drying through Monday.
Humidity remains high enough today that thunderstorms will develop this afternoon in the mountains. Those storms will slide off of the mountains late this afternoon and this evening, but they will have a hard time holding together for long after they cross I-25.
Temperatures warm from 10 AM to noon from the 70's into the 80's. The warm up continues under warm sunshine, and 2 PM will be in the 80's with 90's starting to show along the Arkansas Valley. Between 2 PM and 5 PM, showers and thunderstorms will form in the mountains and move out to the I-25 corridor. The storms will not be widespread, but they will be around this afternoon and evening. Those that do develop could contain some gusty winds and hail.
Thunderstorms will become less widespread tomorrow and less widespread still on Saturday and Sunday as hot high pressure builds over Colorado. Only isolated storms will form in the heat of the afternoon, and they will be most likely over and near the mountains. Temperatures will warm easily into the 90's and triple digits on Saturday and Sunday. The high pressure starts to relax a bit on Monday, and the heat will back off slightly, too. On Tuesday the high pressure eases back enough that scattered afternoon showers and thunderstorms will return to the forecast, bringing even further easing of the July heat.
