Another in a series of fast moving shortwave troughs will move from
the west coast toward the southern Rocky Mountains during the
forecast period. As this trough approaches the Rocky Mountains it
should slow down and deepen, becoming a closed low by early Tuesday.
At the surface, a weak pressure gradient will promote weak surface
winds until late in the period when cyclogenesis across far
southeast New Mexico will result in a strengthening gradient.
...Far southeast Arizona and the southeast half of New Mexico...
Widespread elevated fire-weather conditions are expected across this
region as afternoon minimum relative-humidity values fall into the
10-15%. At this time, surface winds are expected to remain below
critical thresholds (20 mph) owing to a weak surface-pressure
gradient and modest mid-level flow during peak heating. Although
critical conditions may occur on a brief/spotty basis.
