Today, Sunday, should be the hottest day of the Labor Day weekend. Temperatures should be around record levels. The record in Denver is 95 (from 1985) and in Boulder it is 94 (from 2013). Monday will continue the very warm weather, but a cold front sweeping in from the north Monday evening will make it 20-30 degrees cooler on Tuesday, It’s possible that the temperatures will start to cool off by late afternoon Monday along the northern Front Range.
A widespread rain is not expected with the upslope flow behind the front. But there may be a period of low clouds and some patchy drizzle Monday night or Tuesday morning. Fire danger will remain elevated, especially north of I-70 where the summer monsoon was not as generous.
Beyond that the weather in Colorado will not be too exciting (other than the fire danger), and average to above average temperatures are likely to return later in the week. But weather may be making national news again by next weekend as Hurricane Irma approaches the eastern seaboard, an extreme fire danger continue the plague parts of the West.
