SHORT TERM (TONIGHT THROUGH THURSDAY NIGHT)...
MID TO UPPER LEVEL PATTERN IS PROGRESSING AS PREVIOUSLY
ANTICIPATED WITH TROUGH MOVING TO THE MISSISSIPPI VALLEY AND A
RIDGE MOVING ACROSS NM. THIS WILL CONTINUE THROUGH THE SHORT TERM
PERIOD WITH THE RIDGE BECOMING DOMINANT. AT THE SURFACE HIGH
PRESSURE IS CENTERED OVER THE CENTRAL GULF OF MEXICO AND THE LOW
LEVEL WINDS ARE BECOMING SOUTHEASTERLY. THIS WILL BRING GULF
MOISTURE BACK TO THE REGION QUICKLY. THIS WILL BE A DRY PATTERN
WITH WARMING TEMPERATURES.

THERE WILL NOT BE MUCH CHANGE IN THE LONG TERM FORECAST. THE MID
TO UPPER LEVEL RIDGE WILL REMAIN IN PLACE THROUGH THE WEEKEND AND
EARLY NEXT WEEK. MODELS SHOW A SHORT WAVE TROUGH MOVING THROUGH
RIDGE FRIDAY WHICH WILL MEAN A SLIGHT CHANCE FOR THUNDERSTORMS
DEVELOPING OVER THE MEXICAN MOUNTAINS AND MOVING INTO OUR WESTERN
AREA. HAVE INCLUDED A SMALL AREA OF SLIGHT CHANCE POPS FRIDAY AND
