BoulderCAST Daily – Fri 04/03/20 | Foggy but turning sunny

Detailed Forecast Discussion: After last evening's snow, the atmosphere remains rather moist. This has led to fog to start our day as southeasterly upslope flow remains through much of this afternoon. Expect the fog to give way to broken clouds and eventual sunshine for the early afternoon. The sunshine may be brief as more clouds are expected to move in …

Premium Storm Update – Thu 04/02/20 8:30 AM | Some (freezing) drizzle early, snow arrives this afternoon

Detailed Forecast Discussion: Temperatures have dropped like a ROCK overnight following the cold frontal passage that occurred around 8:30 PM last night. Low clouds, fog and drizzle developed as expected, but it's clear from the current temperatures (see below) and widespread coverage of the drizzle that the push of cool/moist air from the northeast was stronger than models were indicating …

BoulderCAST Daily – Wed 04/01/20 | A strong cold front tonight

Detailed Forecast Discussion: Despite the slight concerns we had earlier this week that a cold front would slide in this morning, that will (probably) not be the case! As a result, we thankfully have one more gorgeous spring day to kick off the month of April before things turn uglier tomorrow! A large-scale trough remains inked across the Pacific Northwest...as …

BoulderCAST Daily – Sun 03/29/20 | Increasing clouds with slight chance of sprinkles/flurries late

Detailed Forecast Discussion: Yesterday, we had a west-northwesterly flow as the snow storm pulled out and away from us to our east. Today, the wind turns to be out of the southwest in the mid-levels. This is thanks to a weak trough of low pressure setting up in southern Nevada this evening. It will be tracking to our south tonight …

BoulderCAST Daily – Sat 03/28/20 | Sunny but breezy with highs near 50

Detailed Forecast Discussion: With our snow storm long gone into eastern Nebraska (below), drier air will be working into the state this afternoon and evening. However, there will still be a fair amount of moist air over the region. We will start off with morning clouds. The clouds should slowly decrease through the day with a mix of sunshine and …

BoulderCAST Daily – Fri 03/27/20 | Cold with rain changing to snow, trace to 2″ possible

Detailed Forecast Discussion: As we mentioned in our weekly outlook, there were hints of a snow storm to affect the region on Friday. That has largely come true, along with the colder temperatures. Highs today will likely not rise much after a new batch of colder air works in through the day. Expect temperatures in the upper 30's to around …
