April 2023 concluded as Boulder’s sixth consecutive month with below normal temperatures. At the same time, the Front Range area saw below normal snowfall and precipitation leading to increased drought coverage, though a soggy conclusion to the month did help things a bit. Here’s a quick and colorful graphical recap of our weather during April and how it relates to climatology.

Winter driving conditions this afternoon in the Foothills of western #Boulder County! 4-8" of snow has fallen in these areas. Temperatures in the teens and persistent snow is keeping even the April sun from melting off the pavement! #COwx pic.twitter.com/C2Edq7mH2R

🌡️ Boulder has not hit 70° since November 1st…159 days ago! This is the 14th longest sub-70 streak all-time & the longest since since 2001. This streak comes to an end within the next hour or so!

78" of snow so far this season in Boulder, which is about 4" below normal. In a typical year there would only be about 3" of additional snow after April 20th, though we all know the highly non-scientific "Mother's Day Rule"…. ❄️🥀 #COwx #Boulder #Boulderwx pic.twitter.com/KW9ypTpNEW

❄️WINTER STORM MONDAY UPDATE: While we still have some concerns about the storm’s track & exact snow levels, this will be a classic upslope event with impacts ranging from thunderstorms to soaking rain to heavy wet snow for our area.

First Colorado tornado of the year, a landspout near Keenesburg.

Huge dry slot over #Boulder and the Foothills right now as a persistent Denver Cyclone setup near DIA to the east has been spoiling the party. It seems to be collapsing which should lead to a better surge of moisture/upslope westward, but this definitely cut into QPF output #COwx pic.twitter.com/Pv24EHduN4

Overall a good albeit easy forecast for the lower elevations (which we knew would be too warm for snow), but it was a disaster in the most of the higher terrain.
It wasn't just the Front Range that got short-changed. The Palmer Divide and Colorado Springs did as well #COwx pic.twitter.com/Wkq8kl74pJ

🌡️💦Another spring storm infused with moisture and warm air! Snow accumulations were confined to the Foothills, up to 6" in some cases.
Moisture totals ranged from around 0.1" up north to 0.5" in the south. #COwx pic.twitter.com/3wC2OMyhep
