The weather map over the next several days will be dominated by an upper level storm system – a cutoff low – slowly moving from a position over the central California coast late Thursday to a position over northern Utah by Sunday. Ahead of this low, much of Colorado will be under a warm and mainly dry ridge through at least the beginning of the holiday weekend. Temperatures in Nederland will be in the low to mid 70s with lows in the upper 40s while temperatures on the Eastern Plains will be reaching into the low 90s.
The big question mark in the forecast, or the possible fly in the ointment, will be Memorial Day when the models are hinting at the low starting to lift out of Northern Utah on a track that will take it over Northwestern Colorado and into the northern Plains. This could produce enough lift in the atmosphere to trigger a round of showers and thunderstorms Monday afternoon and evening.
There is always a lot of uncertainty associated with these systems. Suffice it to say for now that most of he weekend is going be nice and the snow pack in the Indian Peaks will be melting quickly.
If you are running the Bolder Boulder on Monday, look for temperatures in the mid 50s at 6 AM rising to the mid-upper 70s by 11 AM. Winds should be light, and any precipitation should hold off until the afternoon. Stay tuned!
