There will be a pretty potent storm system moving across the Rockies Sunday afternoon into Monday. Precipitation is expected over the far west starting Sunday afternoon and spreading into the Rio Grande Valley after dark. Here's a look at what the average precipitation amounts the models are putting out across the Borderland on the left. You can see how the moisture becomes more limited as the system moves east. There is still a 10 percent chance El Paso could see a quarter inch of rain, as seen on the right. This scenario would play out if the system moves further south than expected at this time.
