METEOROLOGICAL CONDITIONS (FRI AM - THU AM)
THE PATTERN THIS MORNING IS SIMILAR TO YESTERDAY WITH STRONG HIGH
PRESSURE CONTINUING TO RESIDE OVER THE INTERIOR OF THE COUNTRY WITH
THE AXIS JUST A TAD TO THE WEST OVER THE ROCKY MOUNTAIN STATES.
ALSO...A WEAK AREA OF LOW PRESSURE CONTINUES TO SPIN JUST OFF THE
COAST OF THE PACIFIC NORTHWEST. FLOW ACROSS MUCH OF THE REGION IS
DRIER AND FROM THE SOUTHWEST...EXCEPT FAR EASTERN NV AND SOUTHERN CA
WHERE PW VALUES ARE STILL HOVERING NEAR OR ABOVE 1.00-INCH. THE KNKX
AND KVEF 17/12Z RAOBS ARE SHOWING THIS ELEVATED MOISTURE WITH 1.59-
AND 1.74-INCHES OF AVAILABLE MOISTURE. THESE AREAS ARE THE LIKELIEST

CONTINUING TO SHOW RIDGING OVER THE INTERIOR AND WEAK TROFFING ALONG
THE WEST COAST. SUNDAY ISN/T LOOKING AS INTERESTING IN TERMS OF
MOISTURE SURGING NORTHWARD...AND NOW LOOKS SIMILAR TO SATURDAY WITH
SCATTERED SHOWERS/T-STORMS OVER EASTERN NV...BUT DRY MOST ELSEWHERE.
THEN THE FOLLOWING WORK WEEK...MOISTURE DOES LOOK TO ADVECT
NORTHWARD ACROSS THE REGION...BRINGING A RENEWED OPPORTUNITY OF
SHOWERS/T-STORMS OVER THE SIERRA (IN PARTICULAR THE CENTRAL/SOUTHERN
PORTION OF THE RANGE)...AND MUCH OF NV.
