Area forecast discussion, May 12, 2:50 AM MST, 10 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PHOENIX AZ
250 AM MST SAT MAY 12 2012

.SYNOPSIS...
WIDESPREAD ONE HUNDRED DEGREE READINGS ARE EXPECTED ACROSS THE LOWER
DESERTS THIS WEEKEND. ABOVE AVERAGE TEMPERATURES WILL CONTINUE
THROUGH AT LEAST THE MIDDLE OF NEXT WEEK AS HIGH PRESSURE REMAINS
THE PREDOMINANT WEATHER FEATURE ACROSS THE DESERT SOUTHWEST.

&&

.DISCUSSION...
ABOVE NORMAL TEMPERATURES WILL BE THE MAIN WEATHER STORY THROUGH
NEXT WEEK. TODAY...SHORT-WAVE RIDGE OFF THE BAJA PENINSULA WILL
PRODUCE A DRY NORTHWESTERLY FLOW ACROSS THE FORECAST AREA. A FEW
DEGREES OF WARMING ARE EXPECTED ACROSS SW AZ BUT THE MORE
SIGNIFICANT WARMING TREND WILL BEGIN SUN. MODELS REMAIN IN GOOD
AGREEMENT INDICATING A WEAK TROUGH WILL SLIDE SOUTHWARD TOWARDS THE
FOUR CORNERS SUN AFTERNOON. DEEPER MOISTURE WILL REMAIN CONFINED
EAST OF AZ...WHILE STRONG SUBSIDENCE BEHIND THE LOW WILL HELP TO
REINFORCE THE HEAT ACROSS THE DESERT SOUTHWEST.

CONTINENTAL EXTENSION OF THE BAJA RIDGE WILL BUILD IN BEHIND THE
DEPARTING TROUGH MON. NEXT EASTERN PACIFIC TROUGH IS EXPECTED TO
WEAKEN RAPIDLY AS IT MOVES NORTH OF THE AREA AND ENCOUNTERS THE
