.PREV DISCUSSION... /ISSUED 0312 AM CST FRI FEB 27 2015/

...SYNOPSIS...
LONGWAVE TROUGHING WILL REMAIN ESTABLISHED ACROSS THE CONUS THROUGH
SAT MORNING. SEVERAL SHORTWAVE TROUGHS WILL ROTATE THROUGH THE BROAD
UPPER TROUGH...WITH ONE OVER THE PACIFIC NW MOVING SWD...AND ANOTHER
OVER THE FOUR CORNERS REGION MOVING EWD. AT THE SFC...AN AREA OF
WEAK LOW PRESSURE LOCATED ACROSS THE LOWER CO RIVER VALLEY AND SRN
AZ EARLY THIS MORNING SHOULD DEEPEN SLIGHTLY AND SHIFT NWWD TO SRN
NV BY LATE THIS AFTERNOON AS THE SHORTWAVE TROUGH OVER THE PACIFIC
NW MOVES INLAND. SLY/SWLY WINDS OF 10-15 MPH WILL LIKELY OCCUR THIS
AFTERNOON AND EARLY EVENING ACROSS MUCH OF SRN/CNTRL AZ AND THE
LOWER CO RIVER VALLEY AS THE SFC LOW DEEPENS. AS AFTERNOON
TEMPERATURES WARM INTO THE 70S ACROSS THIS REGION...RH VALUES MAY
FALL INTO THE 15-25 PERCENT RANGE FOR A FEW HOURS. HOWEVER...THE
MARGINAL NATURE OF THE SUSTAINED WINDS/LOWERED RH ALONG WITH
UNRECEPTIVE/MOIST FUELS SHOULD LIMIT THE CRITICAL FIRE WEATHER
POTENTIAL. GENERALLY COLD TEMPERATURES ASSOCIATED WITH AN EXPANSIVE
AREA OF HIGH PRESSURE AT THE SFC AND PRIOR COLD FRONTAL PASSAGE WILL
GREATLY LIMIT FIRE WEATHER CONCERNS E OF THE ROCKIES.
