BoulderCAST Weather 🏔️⛈️
@bouldercast.com
The official BlueSky account of BoulderCAST, a team of local meteorologists that forecast Boulder and Denver weather as well as nearby mountain conditions.
Real question: How do people actually use weather apps? Says mostly cloudy. That is false. Constantly says 5-10% chance of rain when there is actually zero chance.
FYI: Meteorologists that forecast every day do not use basic weather apps at all.

❄️Multiple waves of snow coming to Colorado's Mountains over the next 10 days which is GREAT news!
🔥 Sadly this moisture likely won't make it down to the Denver-Boulder area where Severe Drought is ongoing. Lots of wind coming NEXT week too which will spike fire danger. #COWX

A prolonged warm, bone‑dry stretch will deepen Mountain snow deficits and increase drought stress in the Front Range. A pattern shift next week will help but won't solve our moisture issues.

This Weekend in Colorado Weather: We have NO business being this warm for this long in February
🌤️ Warm ridge dominates: A sluggish high‑pressure ridge keeps the Front Range quiet, sunny, and unseasonably warm through Monday with highs well into the 60s. 💨 Weak Saturday wave: A moisture‑starved shortwave brings more clouds and some breeziness—strongest winds stay north near the WY border where fire danger may spike. ❄️ Pattern shift next week:...

Flashback to this day 14 years ago when we were waking up to 23" of fresh snow in Boulder!
This remains the city's largest La Niña snowstorm and 9th largest overall since 1948.
This was the final notable snow event that winter before Colorado spiraled into extreme drought #COwx #Boulderwx
