Nice today, not so much tomorrow…Enjoy it!
The spring storm system bearing down on our region came ashore into northern California overnight.

Before this system arrives, Colorado will see strong southerly flow invade today. This will bump our temperatures up a little from yesterday, but also begin the moisture transport to spread high-level clouds across the area. Look for temperatures in the mid to upper 60’s this afternoon with generally thinly clouded skies. The winds could be a little gusty, particularly south of Denver where Red Flag Warnings are posted. Relative humidity levels look marginal at best to meet Red Flag criteria, but still, do be cautious of the primed conditions for fires. Winds could gust in the Boulder/Denver area to 30 mph this afternoon out of the south and southeast.
Big changes come tomorrow as the cut-off low moves across southern Colorado. We’ll have a more detailed look at this forecast posted later this morning, but the system will be too warm to support snow across the Plains. This isn’t our official snowfall forecast, but the GFS model-derived snowfall map below follows our thoughts in most respects. Concern for spring snowfall will be south of Denver across the Palmer Divide, and in the Foothills west of town.

Our storm update later this morning will also discuss the uncertainty surrounding snow levels and the odds of Boulder and Denver actually seeing a few flakes. Stay tuned.
