3/28/26 Saturday 4 am-ish
All models are still in agreement on the next storm. ETA is sometime on Wednesday. I say “sometime” because there is a 12-18-hour discrepancy in when the precipitation starts. Models range from 1 am Wednesday to early afternoon Wednesday.
The GFS shows the earliest start of the precipitation. The Canadian shows the latest start. There are differences in how long the storm lasts. The average of the models shows a duration of about 16 hours.
Then it gets complicated. Will there be a second round of precipitation? If so, will it be on Friday? Saturday? Sunday? Models are really struggling with that piece.
All of the 13 models I mentioned yesterday are still in agreement on the Wednesday storm. But they diverge on the chances of. When (or if) we will see a second storm. I am hoping to get a better read on that by Monday morning.
Here is an updated look at the maps in motion.
First up is the “big picture” view. This allows you to see the storm progression. Also, notice that the “monsoonal signature” in Mexico is still showing up in the models. Lastly, notice the next storm stretching from NW Wyoming down to Salt Lake.
US view from Monday afternoon to Thursday afternoon. Remember, green is rain, blue is snow. The darker the shades, the heavier the precipitation.
Colorado view
This particular run shows slightly lower snow levels (8100 ft). I am not expecting that at this time, but I am watching closely.
My next update will be on Sunday, and we will start delving into precipitation totals from the models.
