DISCUSSION

Issued at 946 PM MST Wed Nov 11 2026

Upper ridge continues to build over the Great Basin and Desert Southwest, ahead of a deepening Pacific trough still off the west coast of the US. Meanwhile the sub-tropical jet remains active with deep layered sub-tropical moisture, but feature will remain well south of our area. Thus the upper ridge is the dominating playa over tonight into early Friday, with mostly clear skies and seasonable temperatures.

Friday and Saturday...Pacific trough finally moves onshore as it continues to dig as very strong polar jet dives down the back side of the trough. As the Gulf of Alaska upper low weakens, a closed off low will form at the bottom of the trough and swing across the northern Baja Friday afternoon. This low will contain a decent amount of moisture and all three of GFS/ECMWF/RRFS showing low able to tap a bit of the sub-tropical moisture over Mexico. Good chance for showers to develop and make it as far east as the RG Valley by late Friday afternoon. GFS still shows good cold air aloft (about 5C deg cooling at 500mb), which should lead to decent instability with very modest CAPES. Because of this, an isolated thunderstorm will be possible with the showers. With the upper low tracking across northern Mexico or far southern New Mexico Friday night along with the surface cold front, showers will spread east over the rest of the area. Expect broad area of .25-.50 of rainfall across the area, with a few spots maybe hitting 1.0 inch with a thunderstorm. Most/all showers should be done in the east by mid day Saturday as the low quickly moves into central Texas. Snow levels will remain high, but an inch or so of snow is possible above 8500 ft. Rapidly moving upper low associated with the polar jet moves in right behind the exiting low but will track across Colorado Saturday night. Rain chances should remain north of the CWA, but could see some breezy winds Saturday night.

Sunday and Monday...short wave ridge sweeps in Sunday behind the exiting lows. Expect mostly clear skies again, but temperatures will be cool, a bit below normal, behind the cold front.

Tuesday and Wednesday...next Pacific system moves in with the low tracking across SoCal and Arizona. Both GFS/ECMWF similar with the track but ECMWF about 6-10 hours faster than GFS. Rain chances increase as early as Tuesday mid day and are likely done by mid day Wednesday. Temperatures will remain below normal.
