Potential for flash flooding & severe weather We kick off the month of August with an absolutely juicy atmospheric set-up in northeast Colorado. We've been hyping this influx of subtropical moisture all week long, and as of writing, it has finally arrived! Conditions are primed for widespread storms to develop today, including tropical downpours, severe storms, and flash flooding, though we suspect that …

Monsoon moisture returns The center of the 500 mb high pressure today is across northeast New Mexico....more-or-less unchanged from yesterday. The persistent southerly flow on the west side of the ridge has helped to bring northward deeper monsoon moisture to Nevada, Utah, western Colorado, and Wyoming. The large-scale clockwise flow around the high and monsoonal moisture influx can be seen …

Near-record heat with a tiny chance of storms The mid-level ridge remains parked across the Rockies today. The center of the high has intensified and is positioned over eastern New Mexico with westerly flow across our region.

The last week of July will feature very seasonal weather in the Front Range as a stationary ridge of high pressure remains across the southern Rockies. While initially suppressed, monsoon moisture will make its way back into Colorado by mid-week. As a result, hot and dry conditions will transition stormier as the week wears on.

Another day of storms, heavy downpours possible High pressure remains situated to our south and west today at 500 mb (below). The tail-end of a weak trough axis that moved through overnight is still lingering across our area this morning with patchy cloud cover and even some light showers hanging around as well. The passing trough has helped to bring …

Hot & stormy with a sprinkle of ozone Storm coverage yesterday was disappointing as convection was confined almost exclusively to the Mountains and Foothills. This was due to subsidence from high pressure in western Colorado, but also a pronounced capping inversion which was present over the lower elevations. The "cap", as we call it, is easily visible below on the left as the bump …
