AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE TUCSON AZ
215 AM MST MON NOV 3 2014

.SYNOPSIS...DRY CONDITIONS WILL PREVAIL INTO NEXT WEEKEND EXCEPT FOR
POSSIBLY A FEW SHOWERS NEAR THE NEW MEXICO BORDER TODAY.  AFTER
RATHER COOL TEMPERATURES TODAY AND TONIGHT...A GRADUAL WARMING TREND
WILL OCCUR FROM TUESDAY THROUGH THE REMAINDER OF THE WEEK.

&&

.DISCUSSION...CORRECTED FREEZE WATCH TO FREEZE WARNING.  THE
REMAINDER UNCHANGED.

CURRENTLY...A DEEP UPPER LEVEL TROUGH EXTENDS FROM SASKATCHEWAN
SOUTHWEST TO 20N LATITUDE OFF THE WEST BAJA COAST WITH SW FLOW
ACROSS SE ARIZONA THIS MORNING.  THERE IS ENOUGH MOISTURE AND
INSTABILITY THAT LIGHT SHOWERS CONTINUE TO CLIP THE SE CORNER OF
COCHISE COUNTY EARLY THIS MORNING.  THIS TREND IS EXPECTED TO
CONTINUE AS THE MAIN TROUGH AXIS VERY SLOWLY SHIFTS EAST.  A SHORT
WAVE ROUNDING THE BOTTOM OF THE TROUGH OFF THE BAJA SPUR SHOULD
ROTATE NE AS THE TROUGH AXIS APPROACHES.  THE COMBINATION OF THE TWO
WITH THE LITTLE BIT OF LINGERING MOISTURE MAY BE ENOUGH TO CONTINUE
THE SHOWER THREAT FOR THE SE PART OF COCHISE COUNTY THUS HAVE
INTRODUCED A SLIGHT CHANCE OF SHOWERS THAT AREA TODAY.  OTHERWISE
DRY AND MOSTLY SUNNY SKIES WITH HIGH TEMPERATURES 10-15 DEGREES
BELOW NORMAL TODAY.  ONLY A FEW LOCATIONS IN THE FAR WESTERN DESERT
AREA WILL REACH 70 TODAY.

THAT COLD AIR MASS REMAINS IN PLACE TONIGHT WITH LIGHT WINDS AND
CLEAR SKIES WHICH WILL END UP PRODUCING THE COLDEST MORNING TEMPS
THUS FAR THIS SEASON...AS MUCH AS 5-10 DEGREES BELOW NORMAL.  GOOD
CHANCE AT BELOW FREEZING TEMPERATURES ACROSS MAINLY COCHISE COUNTY.
THERE MAY BE A COUPLE OF THE NORMALLY COLDER LOCATIONS THAT AREAS
THAT COULD PUSH DOWN INTO THE 20S.

BEYOND THAT...THE UPPER TROUGH SETTLES OVER SONORA MEXICO LATE
TUESDAY THEN SLOWLY HEADS EAST THROUGH THE REST OF THE WEEK.  THIS
ALLOWS HEIGHTS AND LOWER LEVEL THICKNESSES TO RISE AS AN UPPER LEVEL
RIDGE ATTEMPTS TO NOSE INTO THE AREA FROM THE WEST.  THIS WILL
RESULT IN STEADILY RISING TEMPERATURES...PUSHING ABOVE NORMAL ONCE
AGAIN BY THURSDAY UNDER CLEAR SKIES.  AT THIS POINT THE DEVELOPING
WARM AND DRY CONDITIONS LOOK TO LAST THROUGH THE COMING WEEKEND AND
INTO EARLY NEXT WEEK.  CERNIGLIA
