August! Hard to believe. What's maybe not so hard to believe is that the average temperature for July, 2022 ended 2.9°F hotter than average in Denver, with a mean temperature of 78.0°F for the month: You'll note in the image above that Denver officially only logged 0.99" of precipitation in July, which is -1.15" below the longterm average for the month. Well, for once the airport is actually in the minority here, as most stations across the eastern half of the state saw average to above ave

We saw some fantastic rain across much of Eastern Colorado on Sunday, as well as a notable drop in temperatures from the recent heat. Yesterday's high of 87°F was the coolest day in Denver since July 11th when we topped out at 81°F. Since then the city has been trapped in a remarkably hot pattern, with highs most afternoon in the mid to upper 90s and up to 100°F on the 18th. While parts of the metro area again missed on the heaviest precipitation, many stations across Eastern Colorado saw th

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.

Denver hit 100 degrees at Denver International Airport Saturday afternoon. This is the second 100-degree day for Denver this year so far. 98 was the previous record for the date, but now we put 2022 into the record books for July 9th.

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

July La Niña and monsoon update
Plenty to sort through with this update, and based on what I'm seeing we have a lot riding on it too. First, let's look at what La Niña and rest of the global sea surface temperature anomalies have been doing, for the past 90 days. 1. Despite La Niña being very much alive, it has been weakening a bit recently. Notice less blue shading along the equatorial Pacific. 2. The colder than average water that was in the Gulf of Alaska and along the West Coast of the US has also been warming
Denver Forecast
Moisture increases, I'm not excited though
The wet-biased modeling may fool us again with higher storm chances and higher total precipitation estimates than what actually falls, so take this with caution. Monsoonal moisture is increasing across the Four Corners and may pose a flooding risk to portions of Utah and Colorado. A monsoon refresher piece: The North American MonsoonThe North American Monsoon is a seasonal weather pattern developing a persistent wind flow. That pattern brings tropical moisture into Mexico, Arizona, New Mexico,
The North American Monsoon
The North American Monsoon is a seasonal weather pattern developing a persistent wind flow. That pattern brings tropical moisture into Mexico, Arizona, New Mexico, Utah, Colorado and west to south Texas. A well-developed monsoon can spread beneficial rains from the Southwest to the Central and Northern Rockies and can even help the Northern High Plains. The monsoon development begins, on average, in early to late June across Mexico. From there, moisture increases across the Four Corners region

After a nice cool off this weekend, temperatures are set to climb once more this week. Highs were in the 70s both Saturday and Sunday across the area, well below average, and a nice break from the recent heat. Unfortunately, and perhaps not surprisingly, the cooler temperatures weren't accompanied by much precipitation in Denver, with just a Trace recorded at DIA, Denver's official weather station.

Happy to report that at least some of the advertised precipitation for southwest Colorado panned out over recent days, and it looks like more is on the way over the coming week. Precipitation as a percent of normal over the last 7 days shows areas of extreme dry across the south-central plains states and a good portion of California and Nevada, while the Four Corners region was able to tap into some of that monsoonal flow, and the very wet weather across the Northwest continues.

Anyone else remember when it snowed three weeks ago? Storms today have kept us a few degrees cooler across the region, though still quite hot.

Near-record heat this weekend in Denver and around Colorado
It's going to be a hot weekend across the region with some daily record temperatures to be set, the hottest of which will be in Grand Junction that may set back-to-back records of 100 degrees +. This isn't as extreme as the heat expected across the southern and southwestern U.S., however, which will record highs well above 110 in this latest heat wave. The following three maps for Friday, Saturday and Sunday represent the forecast high temperatures that may break existing daily heat records.

Damaging thunderstorms across the region Tuesday
We will have to keep a close eye on our gardens and cars today as damaging thunderstorms are possible across the region. An overview of the outlook area shows potentially severe weather across much of Wyoming, Colorado, Nebraska and Kansas. The highest risk is east of the Denver metro area into Nebraska and Kansas, but that's not to say there is not a risk right here in the metro area too. The risks will include destructive hail and isolated tornadoes. This isn't to say all areas will see t
