.DISCUSSION...
UPPER LEVEL HIGH PRESSURE RIDGE CONTS TO
DOMINATE THE WEATHER FOR
THE DESERT SW...GIVING DRY AND UNSEASONABLY WARM
CONDITIONS TO THE
GRAND CANYON STATE AND THE PHX CWA. NO
CONSEQUENTIAL CHANGES TO THIS

PARTS. THE MORE SIGNIFICANT CHUNK OF ENERGY IS
NOW MOVING THRU THE
PAC NW...RIDING OVER THE TOP OF THE RIDGE...WITH
ONLY 30-50M H5 HGT
FALLS NOTED ON THE 12Z PLOTS. A WEAKER LOW...OFF
THE SRN BAJA COAST
AND WEST OF 120W...IS SLOWLY PUSHING EAST AND
SHOULD REMAIN SOUTH OF
THE STATE OVER THE NEXT COUPLE OF DAYS. THIS
WEAKER SRN LOW HAS BEEN
SPREADING VRBL AMOUNTS OF MAINLY HIGH CLOUDS UP
AHEAD OF IT...AND
THIS BAND OF CLOUDS EXTENDS ALL THE WAY UP INTO

CONTINUE THE TREND OF PUSHING THIS HIGH CLOUD
BAND THRU THE STATE

THERE MAY NOT BE ENOUGH
CLOUDS AROUND TONIGHT TO KEEP THE MIN
TEMPERATURES UP MUCH. H3
ISOTACH FORECAST FROM THE ETA KEEP THE JET CORES
ASSOCD WITH BOTH
LOWS WELL NORTH...AND SOUTH...OF AZ...AND THUS
DO NOT EXPECT MUCH
UPPER FORCING TO OCCUR OVER THE STATE TONIGHT.
WITH LITTLE
DYNAMICS...HIGH CLOUD BAND WILL PROBABLY COME
ACROSS RATHER BROKEN
UP WITH LOTS OF THIN SPOTS. HGTS NOT ADVERTISED
TO CHANGE MUCH THRU
