BoulderCAST Daily – Sat 04/11/20 | Last warm day, cold and snowy tomorrow

Detailed Forecast Discussion: Well today is our last warm day for at least about a week as the polar jet stream brings down some late season arctic air for early April. We should start off today in the upper 60's to around 70 degrees. Clouds will be on the increase as the afternoon wears on. It will be a good …

BoulderCAST Daily – Fri 04/10/20 | Warmth before the snow Sunday

Detailed Forecast Discussion: The California Low has not moved much in the last 24 hours. It's current placement is still near Los Angeles (below). While the system will in no way move northward toward us today, it will bring in some lift out ahead of it later this afternoon and early evening. That will lead to sunshine to start our …

BoulderCAST Daily – Thu 04/09/20 | Increasing clouds with chance of showers in the evening

Detailed Forecast Discussion: The California Low has moved only slightly overnight coming ashore near Los Angeles. Before the sun went down yesterday, GOES-East was showing the impressive low spinning offshore with deep wrap-around moisture flowing into the Desert Southwest (and of course, those mostly sunny skies over Colorado and all of the snowpack in the Mountains!). The current position of …

BoulderCAST Daily – Wed 04/08/20 | Not that much cooler

Detailed Forecast Discussion: The main challenge in today's forecast will be a cold front dropping southward into northeast Colorado this morning. As it turns out, the push of cooler air with this front will largely bypass the Front Range, so much so that we should actually squeeze out another very warm day. The NAM 850mb temperature anomaly forecast animation below …

BoulderCAST Daily – Tue 04/07/20 | Another warm & sunny one

Detailed Forecast Discussion: It will be another warm and sunny day across most of Colorado with continued southwesterly flow pushing across the region. Today's large-scale weather setup (shown below) has a big cut-off low pressure near the California coast. It seems like this has been the exact pattern for the last few weeks. We're always discussing a "California low" early …

BoulderCAST Daily – Sun 04/05/20 | Close to 70?

Detailed Forecast Discussion: Forecast guidance is continuing to show more clouds today relative to yesterday. The regional models are also showing this (below), with morning clouds possible. Part of this could be related to a wave cloud developing in the west-southwest flow. Guidance, however, is indicating that sunshine should become more prevalent as the day wears on. Highs today may …

BoulderCAST Daily – Sat 04/04/20 | Back to warmth

Detailed Forecast Discussion: Well, this weekend is a great way to reverse the effects of the snow we had on Thursday. Any remembrance of the snow is long gone as temperatures rise into the 50's today and 60's tomorrow. Over the course of these next few days, an area of low pressure will once again be setting up over the …
