The week ahead will remain somewhat cooler and drier than normal as a weak trough stays entrenched and monsoon moisture continues to be difficult to come by. However, a favorable setup for severe thunderstorms will exist across northeast Colorado early in the week with hail the main risk. Overall temperatures will stay mostly below normal in the days ahead but they will trend back towards 90 degrees by week’s end.
Temperatures and precipitation ended up about as close to normal as possible for July in Boulder. The month began active with numerous severe weather outbreaks, some of which produced landspout tornadoes in parts of Denver. The last few weeks turned up the heat with a total of fifteen 90-degree days during the month. Here’s a quick and colorful graphical recap of our weather during July and how it relates to climatology.
After a hot and somewhat dry last week or so, monsoon season rapidly ramps up this week across Colorado! Deep and anomalous subtropical moisture will surge into the area potentially reaching record levels which will carry the threat of flash flooding across the Front Range. By the latter part of the week, there are some signs that the ridge may move northwestward, possibly pushing the deepest monsoonal flow to our north aiding in some drying. Nevertheless, showers and storms will exist in the forecast every single day this week, especially Monday through Wednesday when flash flooding will be a major concern. Let’s discuss this wet setup!
