...SCATTERED PRECIP SOCAL COASTAL MTNS TODAY-THU SPREADS OVER
SOUTHERN SIERRA AND SOUTHERN NV WED-THU...
METEOROLOGICAL CONDITIONS (TUE AM - MON AM)
OVERALL PATTERN THIS MORNING SHOWS A S/WV TROF MOVING FROM THE
PACIFIC NORTHWEST TOWARD THE NORTHERN ROCKIES...WHILE AN OFFSHORE
UPR LOW IN THE VICINITY OF 37N/134W SPINS SLOWLY TO THE SOUTHWEST.
ALSO...STRONG HIGH PRESSURE CONTINUES TO ENCOMPASS THE SOUTHERN
PLAINS STATES. LOOKING AT AVAILABLE MOISTURE...THE MAJORITY OF THE
ELEVATED MOISTURE REMAINS ACROSS SOUTHERN CA WITH THE KNKX 08/12Z
RAOB INDICATES A HEALTHY 1.79-INCHES OF PW...DROPPING OFF AS ONE
PROGRESSES NORTHWARD WITH KVEF RECORDING 1.10-INCHES OF PW. FOR
TODAY...WITH ENOUGH DAYTIME HEATING AND THE AMPLE AMOUNT OF
MOISTURE...SCATTERED AFTERNOON SHOWERS AND T-STORMS WILL BE POSSIBLE
OVER THE HIGHER TERRAIN OF COASTAL SOUTHERN CA.
FOR WEDNESDAY INTO THURSDAY...THE STRONG HIGH PRESSURE OVER THE
SOUTH-CENTRAL PORTION OF THE COUNTRY WILL BUILD WESTWARD OVER THE
DESERT SOUTHWEST BRINGING WARMER TEMPERATURES TO MUCH OF THE
REGION...AND POTENTIALLY DRAWING SOME OF THE MOISTURE FROM SOUTHERN
CA A BIT NORTHWARD. THIS WILL INCREASE AFTERNOON SHOWER AND
THUNDERSTORM CHANCES ON WEDNESDAY INTO THURSDAY FROM THE COASTAL
MOUNTAINS OF SOUTHERN CA OVER THE SOUTHERN SIERRA AND POINTS
EASTWARD ACROSS THE SOUTHERN HALF TO TWO-THIRDS OF NV.
TO WRAP UP THE WEEK...A COUPLE DISTURBANCES MAKING THEIR WAY
SOUTHWARD ALONG THE AK AND BC COAST WILL SHIFT INLAND ACROSS THE
PACIFIC NORTHWEST...FLATTENING THE UPR RIDGE A BIT. THE SECOND AND
STRONGER S/WV TROF ALSO LOOKS TO BRING A POTENTIAL FOR SOME LIGHT
PRECIP NEAR THE CA/OR BORDER INTO FAR NORTHERN NV ON SATURDAY AND
LINGERING INTO SUNDAY. FOR THE FOLLOWING WEEK...FLOW ONCE AGAIN
BECOMES DRIER FROM THE SOUTHWEST.
