These are the time window predictions with a full geophysical model for rain on Saturday, March 11. The images are every three hours: 3am, 6 am, 9 am, noon and 3 pm. It translates to very likely wet weather, but not heavy down pours.
For those interested in the details: this weather system will be the combination of a rich moisture surge from the Gulf of Mexico and a strong cold front moving east to west (back door) across NM. There will be thunderstorm activity along the leading edge of this front which is forecasted to push into the Jemez area Friday night and Saturday. The precipitation will be “drizzly” with occasional embedded thunderstorms. The level of activity will depend on how far and how fast the cold front pushes into our area. The precipitation maximum will likely be later on Saturday and could be more of an impact for the 50 milers.
