NORTHWEST FLOW ALOFT BEHIND THIS SYSTEM. IR IMAGERY SHOWS CLEAR
SKIES AND MAINLY DRY FLOW OF AIR UPSTREAM. WATER VAPOR AND IR
IMAGERY DO SHOW SOME RESIDUAL MOISTURE HOWEVER ACROSS WHITE PINE
COUNTY THIS MORNING AND FLOW AROUND THE WEAK TROUGH OFF THE CENTRAL
CA COAST IS WEST TO SOUTHWEST ALOFT. 12Z ETA AND 06Z AVN INDICATE
THAT THIS FLOW WILL PERSIST THROUGH THE EVENING ACROSS THE CWFA...
CREATING A BOUNDARY LAYER CONVERGENCE ZONE OVER WHITE PINE COUNTY
THIS AFTERNOON AND EVENING. ELKO WSR-88D INDICATED THAT SOME
SIGNIFICANT RAIN FELL ACROSS THIS AREA YESTERDAY AFTERNOON...AND
DAYTIME HEATING AND EVAPORATION OVER THESE AREAS WILL ALSO

PROVIDE A REINFORCING SHOT OF COOL AIR SATURDAY NIGHT. AFTER THIS
FEATURE MOVES TO THE EAST LATE SATURDAY NIGHT...THE LARGE RIDGE
