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.

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

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.

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
