Monday evening forecast: Patchy fog in some areas tomorrow with cold front coming Tuesday night

ALBUQUERQUE, N.M. – Patchy dense fog could cut visibility around Roswell and the lower Pecos Valley early Tuesday, while most of New Mexico stays clear, dry and quiet.

Most of New Mexico will remain clear, dry and quiet tonight as high pressure continues to dominate the Southwest. With clear skies and light winds, temperatures will drop quickly after sunset.

Overnight lows should stay fairly similar to what New Mexico saw the night before.

The main weather concern late Monday night into Tuesday morning will be across the lower Pecos River Valley and nearby eastern plains. Patchy fog and low clouds are expected to develop, with the better chances favoring Roswell, the lower Pecos River Valley and the adjacent caprock.

High-resolution forecast guidance shows a 40 to 70 percent chance for patchy dense fog in parts of that area. Visibility could become locally poor during the early morning hours around Roswell.

The fog should be patchy rather than solid across the entire area, but drivers around Roswell and the lower Pecos Valley could run into rapid changes in visibility.

The low clouds and fog should begin lifting by mid-morning Tuesday as temperatures warm and winds become light and variable.

Outside of the early fog in southeastern New Mexico, Tuesday will be another quiet day with mostly clear skies, light winds, dry weather and temperatures a little below normal for this time of November.

No rain or snow is expected Tuesday. Tuesday night will turn chilly again, and the latest forecast also lowered overnight lows.

Midweek changes ahead

A weak cold front will begin moving into eastern New Mexico from the north and east Tuesday night. That will start the only noticeable weather change during the middle of the week.

By Wednesday, the front will push south and west across the eastern plains, bringing a wind shift, breezy north to northeast winds and slightly cooler temperatures. The biggest change will favor Clayton, Tucumcari, Clovis, Portales, Roswell and the eastern plains.

Central and western New Mexico will remain on the milder side of the front, with afternoon temperatures in the low to mid-60s. Eastern New Mexico will be a little cooler behind the front, with highs generally in the upper 50s to low 60s.

The forecast stays dry through Wednesday, and there is not enough large-scale lift to produce rain or snow.

The front may also push cooler air through the gaps of the central mountain chain, which could bring stronger east or northeast winds to parts of the lower Rio Grande Valley, the upper Tularosa Valley, Socorro, Alamogordo and Tularosa. This does not currently look like a major gap wind event, but some locations could turn noticeably breezy.
