DayCAST: Sat 04/30/16

Have't had time to fully review what has happened with the storm, but it appears the wrap-around moisture we were hopeful for Friday night did occur/is occurring. It looks like snow totals, as we warned yesterday, ended up towards the low end of our forecasts. Light snow, mixing with rain, will continue through the day. Little to no additional accumulation is expected …

Most of our current thoughts about the ongoing spring storm are summarized nicely in our post last night. Below is our forecast snow map. Since that post, models have continued to trend drier across the Boulder area, likely the result of upslope remaining relatively weak throughout the event. Without the upslope, lift will be weaker, and snowfall rates won't be as …

The system we have been discussing since Sunday is knocking on the door this morning... We'll see light rain (maybe some snow mixing in as well) form by mid to late morning across the Front Range. At the onset, it will be quite light, but will increase in coverage and intensity through the afternoon and into the evening hours. Widespread moderate precipitation …

With a bit of downslope flow across the region today, we'll see more drying and sun compared to previous days. The downslope can be seen in the NAM 500 mb vorticity map for this evening. Notice the northwesterly flow aloft on the backside of the system in Nebraska. You will also notice our next weather system in California. Associated with this …

Today will be similar to yesterday. The storm system of interest will be centered over northwest Colorado this afternoon. The best lift for precipitation will once again remain west and north of our region (like yesterday). However, we'll be situated in the "warm" and convective sector of the storm, so we can't fully rule out some showers across the region today. The best …

The trough that brought the gusty winds last night and a sprinkle of rain is already moving out of the region (seen below centered over the Dakotas). In its wake, a tiny shortwave ridge builds in this afternoon. The cold air and energy associated with the trough only clipped our region.  Notice how relatively warm air rebuilds across the eastern part of …

DayCAST: Sat 04/23/16

Yesterday's high was 82 degrees in North Boulder...our warmest day thus far in 2016! We'll be a tad cooler today as a trough approaches from the west, just skirting the northern portion of Colorado this evening. Ahead of the trough, strong southwesterly winds will be in place across the region. Gusts up to 50 mph will be possible during the afternoon …
