...Southern New Mexico...
A closed upper-low drifting east along the U.S.-Mex border into
West Texas will maintain mid-level divergence across southern New
Mexico through Wednesday night into Thursday. This divergence
aloft coupled with low-level northeasterly flow will support
periods of light to moderate snow along the Sacramento Mountains.
While widespread heavy accumulations are not expected, WPC PWPF
does show some low probabilities for local amounts of 4-inches or
more across this region.
For Days 2-3, the probability of snow accumulations greater than 4
inches is less than 10 percent.
For Days 1-3, the probability of significant icing (0.25 inch or
more) is less than 10 percent.
This is the final regularly scheduled heavy snow/significant icing
discussion of the season. Regularly scheduled discussions will
resume on or about October 1, 2021.
