.DISCUSSION...VERY STRONG LOW LEVEL CONVERGENCE IS OVER EXTREME
SOUTHWEST OREGON THIS MORNING IN THE LEFT EXIT REGION OF A 145KT
JET AS THE REGION REMAINS IN THE RECEIVING END OF THE TRANS
PACIFIC PINEAPPLE EXPRESS. THIS IS RESULTING IN A VERY STRONG BAND
OF PRECIPITATION COMING INTO THE SOUTHERN CALIFORNIA COAST AT THIS
TIME. AS THE CLOSED UPPER LEVEL LOW MOVES INTO THE CENTRAL OREGON
COAST WINDS WILL REMAIN STRONG..PRIMARILY FROM CAPE BLANCO
SOUTHWARD AS LOW LEVEL WINDS CONVERGE ON THE SOUTHERN OREGON COAST
THIS MORNING. THE COMBINATION OF STRONG DRIVING WINDS AND YET
ANOTHER ROUND OF HEAVY RAINFALL WILL ACT TO INJECT MOISTURE DEEP
INTO EXPOSED HILLSIDES...MUCH LIKE A PNEUMATIC INJECTOR FORCES
INOCULATIONS INTO THE SKIN WITHOUT A NEEDLE...CAUSING PRIME
CONDITIONS FOR SLIDES TO CONTINUE IN THE COASTAL REGION. THE WARM
CONVEYOR FLOW KEEPS SNOW LEVELS GENERALLY ABOVE 5000 FEET THIS
MORNING UNTIL THE VERY TRAILING EDGE OF THE FLOW ENTRAINS COLDER
AIR IN BEHIND IT...BRINGING SNOW LEVELS DOWN TO AROUND 4000 FEET
BY THIS AFTERNOON. THE CLOSED LOW OPENS THIS AFTERNOON AS THE
UPPER TROUGH MOVES INLAND WITH THE COLD AIR BEHIND ALOFT INCREASES
LAPSE RATES IN STRONG ONSHORE FLOW...MAINTAINING MODERATE SHOWERS
MOSTLY IN THE HIGHER TERRAIN. BRIEF RIDGING BRINGS A WELCOMED
BREAK ON THE TAIL END OF SPRING BREAK SUNDAY INTO MONDAY EVENING
WHEN MODELS ARE IN VERY GOOD AGREEMENT BRINGING THE NEXT ROUND
INTO THE REGION AND ALLOWING MOST RIVERS TO SUBSIDE SUBSTANTIALLY
AHEAD OF IT.
