.DISCUSSION... Issued at 1020 AM MDT Wed Sep 10 2025
High pressure aloft is shifting more to the east in response a strengthening low pressure system moving onshore in the Pacific northwest. There is a northward moving mid level plume of moisture caught between the low and the high that is straddling the Arizona/New Mexico state line. This moisture, plus modest low level moisture from the south, will help generate isolated thunderstorms for the mountains of the Gila Region and the Sacramento Mountains this afternoon and evening. In addition isolated thunderstorms will occur over the lowlands west of the Continental divide closer to the Arizona state line where moisture is more plentiful. Flooding concerns away from burn scars remains low. Afternoon temperatures will again be 6 to 10 degrees above normal this afternoon. The area is expected to remain below the 100 degree mark. This pattern will largely repeat on Thursday afternoon and evening.
For Friday and the weekend the large Pacific northwest low will gradually drift eastward. South to southwest flow ahead of the system will continue pull additional moisture up over the area shift the deeper part of the plume more over New Mexico. The additional moisture will increase chances for showers and thunderstorms each day. Periods of moderate to briefly heavy rainfall will occur with some localized flooding potential. In this dynamic environment with speed and directional shear in the wind profile, some of the storms may become strong and near severe levels, capable of producing some larger hail. The potential strength of these storms remain uncertain at this time. In addition to the increased moisture, day time temperatures will be on a cooling trend toward seasonal averages by Monday.
The weather pattern for Tuesday and the rest of next week is more uncertain with a lack of consensus among the long range model ensembles. There will continue to be at least a slight chance of showers and thunderstorms as transitory low pressure systems move across the area as part of the westerly flow pattern. Temperatures will remain seasonal through the end of next week.
