.DISCUSSION... Issued at 1008 PM MDT Mon Sep 8 2025
Upper level high pressure will continue to control our weather tonight and into Tuesday. That will keep us mainly dry and help afternoon high temperatures run 5 to 7 degrees above average. There may be just enough moisture for a few short lived showers and thunderstorms in the mountains, but they won`t last long or produce much rain. By Wednesday, the upper level ridge will set up home for a few days over west Texas, while at the same time an upper level trough will be coming into the west coast of California. The circulation around these two features will pull up a narrow ribbon of moisture from the south. On Wednesday, the narrow moisture plume will be centered over far eastern Arizona. We may see a few storms develop right along the New Mexico and Arizona border. The rest of the area will stay dry, with high temperatures still running around 5 degrees above average. By Thursday, the narrow ribbon of moisture will push a little east and that will be enough to help fuel some thunderstorms mainly east of the Continental Divide. But like Wednesday, most of the region will stay high and dry with high temperatures still running around 5 degrees above average.
By Friday the ribbon of moisture will slowly push a little further east to central New Mexico. This moisture plume is not very strong, so I`m not expecting a whole lot of thunderstorm activity, but hey, any rain we can get is a good thing. For Saturday and Sunday the narrow plume of moisture will be over the eastern part of the area, mainly east of the Rio Grande, which will lead to isolated to scattered thunderstorms both afternoons. By next Monday, the upper level ridge to our east will push back west some, while the upper level trough to our west deepens a little further. This will push the moisture plume back west of the Rio Grande and with the dynamics of the upper level trough to our west, a few storms may be strong. Temperature for this coming weekend into the start of next week, look to continue to run a few degrees above average.
