March 2023 concluded as the coldest March in more than 50 years in Boulder and was our fifth consecutive month with below normal temperatures — this winter has been atypically long and brutal. Despite heavy snow fueled by atmospheric river events in the Mountains, very little precipitation reached east of the Continental Divide during March with fire danger and blowing dust increasing substantially by month’s end. Here’s a quick and colorful graphical recap of our weather during March and how it relates to climatology.

🌊 The moisture influx to Colorado with this (dying) atmospheric river event has been rather impressive!

Heads up! Confidence growing for a tricky AM commute for the northeastern Metro area tomorrow as a surface low forms along a frontal boundary. This radar simulation is for 8AM. Areas along and east of I-25 at greatest risk for moderate to heavy snow early Monday #COwx pic.twitter.com/5zvf5TMoyQ

Preliminary snow totals indicate a general Dusting-4" across the Metro area, with a booming 5-7" from Longmont to Loveland where pockets of heavy snow stalled overnight –> https://t.co/blmmB92lUD #COWx pic.twitter.com/pdAVY88AX3

Pick your poison today in Colorado weather! 🏭 or 🔥?
We've got gross air out there on the northern Front Range, including #Boulder, which still has not escaped the inversion yet. Areas in green have clean air, but it's also very warm & windy with dangerous fire conditions! pic.twitter.com/uQMMmKljQq

In case you are curious, the temperature rise in #Boulder on Thursday was gradual and typical. However, our immediate proximity to the terrain makes temperature rises here more intense than Denver. There has been three 29°+ one-hour jumps in just the last 8 years alone… #COwx https://t.co/ipU0JO8ZtZ pic.twitter.com/3Wpq1ljL6R

The #HogbackFire is estimated at 10 acres & growing- pushed by extremely strong winds. It’s moving from near Alameda & C470 to the southeast. This video is from the west side of the hogback, on the side the fire originated. Wind pushed it upslope and over the top of the ridge. pic.twitter.com/EQF3Uewir7
