..SYNOPSIS
A MIDLEVEL TROUGH WILL MOVE EASTWARD FROM THE GREAT BASIN INTO THE
CENTRAL ROCKIES TODAY. WITHIN THE BASE OF THE TROUGH, A BELT OF
MODERATE DEEP-LAYER WESTERLY FLOW WILL OVERSPREAD THE SOUTHWEST INTO
THE SOUTHERN ROCKIES. IN RESPONSE TO THE EASTWARD-MOVING TROUGH, A
LEE CYCLONE WILL DEEPEN OVER THE CENTRAL/SOUTHERN HIGH PLAINS, WHILE
A SOUTHWARD-EXTENDING DRYLINE SHARPENS OVER THE SOUTHERN HIGH
PLAINS.
..WESTERN NM AND EASTERN AZ
IN THE WAKE OF POOR OVERNIGHT RECOVERIES, STRONG DIURNAL
HEATING/MIXING OF A DRY ANTECEDENT AIR MASS WEST OF THE DRYLINE WILL
YIELD WIDESPREAD SINGLE-DIGIT RH ACROSS MUCH OF AZ AND NM DURING THE
AFTERNOON. SUBSTANTIAL BOUNDARY-LAYER MIXING INTO THE ENHANCED
DEEP-LAYER FLOW, COUPLED WITH A TIGHTENING PRESSURE GRADIENT
PERIPHERAL TO THE LEE CYCLONE, WILL SUPPORT 20-25 MPH SUSTAINED
WESTERLY SURFACE WINDS AMID THE LOW RH AND HOT SURFACE TEMPERATURES.
THIS COMBINATION WILL FAVOR CRITICAL FIRE-WEATHER CONDITIONS ATOP
DRY FUELS IN WESTERN NM AND FAR EASTERN AZ.
