.SHORT TERM... (Today and tonight) Issued at 1251 AM CDT Sat Sep 13 2025
A deep upper trough is currently driving significant monsoonal activity across New Mexico. Cloud cover will increase through the overnight hours as it shifts eastward. This will keep lows moderated, generally in the mid 60s. While the main mid-level trough axis will be moving over the Four Corners region, an initial wave out ahead of it will track near the TX/NM border by mid-morning. Firstly, this will lead to somewhat elevated southerly surface winds, potentially peaking near 20 mph in the afternoon. Secondly, it will bring showers and thunderstorms, mostly west of the I-27 corridor. Dewpoints continue to significantly drop farther east front the mid 60s in the aforementioned region to near 50 off the Caprock. Combined with the main upper jet taking a more northeasterly track, this should prevent storms from making it very far east in our area.
The main through axis will move over the area tonight into early Sunday, bringing additional shower and thunderstorm chances for much of the region. PWATs for both rounds of precipitation remain elevated, potentially exceeding 1.5" for the second round. As such, heavy rain will be the rain threat, however hail and brief strong winds cannot completely ruled out. Despite the cloud cover/precipitation, the southerly flow will allow for warmer temperatures will continue with highs generally ranging from the mid 80s to near 90 off the Caprock.

.LONG TERM... (Sunday through Friday) Issued at 1251 AM CDT Sat Sep 13 2025
The upper trough mentioned above will continue to bring scattered showers and thunderstorms to the area through Sunday. Again, heavy rain remains a threat with potential training storms, however this is not expected to be very widespread. Precipitation should taper off by the evening hours as the trough departs to the north and east. The upper pattern becomes messy thereafter. However, generally southerly winds will continue, keeping temperatures on the warmer side with highs consistently each day in the mid 80s to near 90. An upper trough will move over the Great Plains around the mid-week time frame. Slight storm chances may occur over portions of the area Monday near a weak shortwave, but confidence for this remains low. Highest precipitation chances would be late Wednesday into Thursday as the main axis passes over our area. A strong ridge building to the southwest looks to bring further warmer and drier conditions Friday into next weekend.

.AVIATION... (12Z TAFS) Issued at 603 AM CDT Sat Sep 13 2025
Scattered rain showers and thunderstorms are expected to spread eastward this evening with greatest chances affecting KLBB and KPVW. No mention was made in the TAF at KCDS due to lower chances at that location. Low CIGS may move into the KLBB and KPVW terminals after the thunderstorm activity moves east of the terminals but uncertainty is too high to mention in the TAF at the moment.
