BoulderCAST Daily – Tue 06/23/20 | Seasonal with a few afternoon and evening storms

TDetailed Forecast Discussion he large-scale pattern has changed very little from yesterday with a ridge of high pressure to our west and a trough to the east. In-between, northwest flow will continue across Colorado as the ridge builds ever-so-slightly eastward today. We're still just on the very eastern edge of the ridge. Similar to yesterday, morning sunshine will transition to …

BoulderCAST Daily – Sun 06/21/20 | Scattered storms this evening

Detailed Forecast Discussion Highs to remain on the warm side on this Sunday, albeit with increasing cloud cover.

As seen below, we're only starting out a few degrees cooler this morning across the Plains, but it is 10 to 15 degrees colder in the Mountains due to stronger cold air advection aloft. Highs will …

BoulderCAST Daily – Wed 06/17/20 | Hooray! A cold front arrives this evening

FDetailed Forecast Discussion: or some of you, today will be the sixth consecutive 90+ degree day with temperatures once again poised to just eclipse the 90-degree mark. Moderately strong south to southwest flow is the story today ahead of a Pacific trough approaching from the northwest. The animation below shows the trough's movement over the next few days.
