Let's see how they do on it. This one looks pretty good. Here's the morning NWS discussion on it:


.DISCUSSION...
CURRENT SAT TRENDS AND INCOMING 12Z MODEL DATA INDICATE FORECAST IS
ON TRACK WITH THE APPROACHING WEST COAST TROUGH AND ASSOCIATED LOW
PRESSURE SYSTEMS. EXPECTING A RATHER DRAMATIC INCREASE IN MOISTURE
AHEAD OF THE FIRST LOW...WITH A GOOD SOUTH/SOUTHWESTERLY MOISTURE
ADVECTION INTO THE LOWER DESERTS THIS AFTERNOON THROUGH SATURDAY.
STRONG JET DYNAMICS AND FRONTOGENETIC FORCING WILL RESULT IN STRONG
LIFT FROM OUR SOUTHWEST AZ ZONES EASTWARD SAT AFTERNOON AND
OVERNIGHT FOR THE FIRST BIG PRECIP EVENT. QPF/S ARE ON THE ORDER OF
THREE QUARTER INCH ACROSS THE LOWER SOUTH-CENTRAL DESERTS...HIGHER
AMOUNTS TO THE NORTH AND EAST WHERE THE SOUTH/SOUTHWESTERLY FLOW
WILL AID IN OROGRAPHIC LIFT AND HIGHER PRECIP AMOUNTS. THIS FIRST
SYSTEM WILL THEN EXIT RATHER QUICKLY SUNDAY...WITH A BRIEF PERIOD OF
DOWN TIME BEFORE A MUCH STRONGER AND COLDER LOW DIVES SOUTHWARD FROM
AN INLAND TRAJECTORY... LOWERING SNOW LEVELS SIGNIFICANTLY AND
BRINGING ANOTHER ROUND OF VALLEY RAIN AND HIGHER TERRAIN SNOW.
OVERALL...THESE TRENDS ARE HANDLED VERY WELL IN THE CURRENT FORECAST
AND DIGITAL DATABASE...AND NO UPDATES ARE PLANNED FOR THIS MORNING.
PREVIOUS DISCUSSION STILL VALID...
