September was warmer than normal across New Mexico. Precipitation in most areas was below normal although small areas across western New Mexico were above normal.
The month began quiet as high pressure continued over the state. Temperatures were above normal with a few record highs in the east. Thunderstorms were few and far between on the 1st and 2nd. The coverage increased gradually from the 3rd through 6th. A strong back door cold front on the 7th sent temperatures plummeting in the east, and strong winds into the Rio Grande Valley late on the 7th. Meanwhile showers and thunderstorms fired in the west and south. A reduction in coverage on the 8th and 9th was followed by more active days on the 10th and especially 11th through 13th. The middle of the month was mostly dry. A strong east canyon wind blasted into the Rio Grande Valley on the evening of the 17th with a peak wind gust of 70 mph at the Kirtland Air Force Base. A gradual increase in moisture from the 22nd through 27th led to isolated to scattered showers and thunderstorms. In particular, some moisture from the remains of Hurricane Miriam delivered rain to the Southeast Plains on the 28th. Moisture recycled through the rest of the month.
