...CRITICAL FIRE WEATHER AREA FOR SOUTHEASTERN ARIZONA INTO THE

SOUTHERN HIGH PLAINS...



...Synopsis...

A strong upper-low will move through the Great Basin and reach the

Four Corners toward by midday. Strong mid-level flow will develop on

the southern flank of the low across much of central Arizona

eastward into central/southern New Mexico. At the surface, a cyclone

will deepen along the Kansas/Colorado border before evolving into an

elongated surface trough from the southern High Plains northeastward

through eastern Nebraska by early evening. A cold front will

progress through the Southwest and into the Southern Plains.



...Southwest and Southern High Plains...

Widespread critical fire weather is likely to occur tomorrow

afternoon. The strong mid-level winds will be favorably timed with

peak boundary-layer mixing across New Mexico, especially.

Single-digit RH is probable over much of the region increasing to

around 15% around the fringes of the risk area. The deepening

surface low will help to enhance surface winds to 20-30 mph. Locally

extremely critical conditions may occur, particularly in southern

New Mexico border where the mid-level jet will be. However, ERCs are

only near the 50th percentile which should limit more extreme fire

behavior. Elevated conditions will extend both westward and eastward

where weaker winds and marginal fuels will limit critical fire

weather, respectively.
