Record temperatures for parts of Colorado will move in the next few days; of them, Grand Junction will be the hottest with the daily record of 104°F in jeopardy on Monday. Here are the daily highs for a few locations within the region. For Denver, we are within a degree of record highs as currently forecast for Monday (record 102°F) and Tuesday (record 99°F), so needless to say both days have the potential to tie or break the record high for the date. This is part of the extreme heat that ha

The warmest temperatures in more than six months will be here today and tomorrow and will likely set records for Denver.

March 2023 won't end up on any top 20 lists as it ended colder than average (but not historically so) and less snowy than average (but not historically so). The average temperature in March in Denver ran -5.7°F below the longterm average, with a mean temperature of just 35.9°F. The coldest March on recorded had a mean temperature of just 26.4°F, back in 1912, but to make the top 20 coldest, 2023 would have had to come in at 35.5°F or colder. Oh so close!

While we set daily records for the heat, there is relief on the way and it looks relatively significant. High temperatures by the weekend may struggle to reach the 60s!

The heat from Labor Day weekend continues and will last for much of the workweek ahead, with Denver's existing record highs to fall the next few days.

Good morning and welcome to the first full week of September. September marks the start of meteorological fall, or as we've come to know it in recent years around here the height of our summer heat! September 2022 has kicked off in the same tradition: exceptionally hot. This week we will be under the influence of a remarkably strong ridge across the West, which will lead to record-setting heat for much of the Western CONUS. Two meter temperature anomalies over the next 5 days shows the drama

It's going to be a hot start to the week, with a potential record set for Denver by hitting 100 degrees. This heat isn't unique to the Front Range or Colorado as it is widespread Sunday and Monday. A ridge of high pressure will continue to provide above normal and record-breaking heat for the western and central U.S. Sunday. Parts of Montana will climb well above 100 degrees, Billings can set a new record high by hitting a forecast high of 102 Sunday. Per the WPC, "Approximately 30 million re

Hot weather moves in for the weekend as the region sees a drop in rain chances, too. Denver to come to near 100 degrees both Saturday and Sunday. What's happening? A ridge of high pressure will be dominating the western/southwestern U.S. for the next several days. A ridge is an area of relative calm, suppressing rain chances, and bringing heat this time of the year. This ridge is basically centered on Colorado and New Mexico. As a result, look at the temperatures forecast for Colorado from F

If you've looked at the horizon Monday you have seen the haze in the air. This is mostly smoke arriving from the Pipeline Fire near Flagstaff, AZ . The smoke likely gets thicker this afternoon with some relief with a wind shift to come Tuesday. > Some of you have asked about the smoky sky this morning. That smoke alof

Record heat in September has become something of a staple in recent years. Even last year, which saw one of the earliest snowfalls on record in Denver, boasted some extreme September heat as well. You can revisit the remarkable week in weather we had a year ago at this time below, when we went from triple-digit heat to snow in a matter of a couple days. Here’s the long list

There's going to be a transition within the atmosphere from late this week through early next week that will bring cooler temperatures and higher rain chances to most, if not all, of Colorado. This transition is part of the seasonal monsoon pattern that is trying to establish itself across the American Southwest. In this case, the monsoonal pattern is breaking down and shifting west, during which some moisture from the Northern US will be moving from north to south across the state. Remember,

For those of us living across eastern Colorado, western Kansas, and the Texas/Oklahoma panhandles the recent streak of moisture has been a welcome but a bit of a surprise buck of the overall trend across the western U.S. which continues to see drought grow and intensify. In recent months we've stressed the drought severity across the west, and increasingly so across the northern High Plains. While those immediately east of the Continental Divide and south of the Dakotas have benefited from an

Tuesday and Wednesday both hit 100-degree heat and the city will make a run at it again Thursday. Tuesday hit a high of 101 . Wednesday hit 100. Both of those record setting highs.

The incredible heat recently isn't just isolated to Colorado. As we've

For the first time since last September, we may record 100 degrees early this week. As discussed in Sunday's SOTA, hot weather sticks around a few days this week with records to fall across the area and across the Western US.

Temperatures will be near to and will set records this week - prepare for a hot one! The hottest temperature so far this year has been 95 in Denver, 94 in Fort Collins, 98 in Greeley, 91 in Boulder, 87 in Castle Rock, and 93 in Colorado Springs. We are likely to see those numbers replaced this week. The setup: A very large dome of high pressure will be in place this week across the Western US. Let's call it a Drought High as its presence will be reinforced by the significant drought conditions

Monday will feature more record setting warmth across the state ahead of our next weather system. The forecast of 82°F for Denver today would tie the previous record for the date set in 1991, should it verify, and some guidance suggest we could even break that high by a degree or two. Sunday we saw many daily records fall across a huge portion of the country, including many long standing records across Colorado. With a high of 80°F Sunday in Denver, we broke the old record for the date by 4°F

It was another stunning day for temperature records across the Western United States, including across Colorado. Denver was spared setting yet another couple of records today, likely thanks in part to the Cameron Peak Fire smoke plume that moved over the city early afternoon and helped keep temperatures just a hint cooler than they otherwise might have been. Still, Denver tied the record high for the date with DIA hitting 97°F degrees this afternoon, a record first set back in 2013. The ma
