PRECIP SLOWLY COMING TO AN END FROM WEST TO EAST...AND THOUGH MUCH OF IT SHOULD CLEAR BY 18Z...KEEPING SOME POPS THROUGH THE AFTERNOON IN THE EAST MOSTLY TO BLEND AND COVER ANY REMNANT SHOWERS WITH A SLOWING BOUNDARY. TONIGHT COOLER ACROSS THE BOARD WITH LOWS AT OR JUST BELOW FREEZING. LONG TERM...TUESDAY THROUGH FRIDAY... SLOW RISE IN TEMPS AGAIN...WITH ALL OPERATIONAL MODELS HINTING AT A PASSING WAVE JUST NORTH OF CWA FOR TUESDAY NIGHT INTO WED MORNING. BOTH 00Z ECMWF AND 00Z NAM/WRF KEEP THE PRECIP WELL NORTH. NOTHING JUST YET IN THE GRIDS...BUT WILL HAVE TO KEEP AN EYE OUT FOR ACTUAL REPRESENTATION OF THIS PARTICULAR WAVE IN STRETCHING OUT FLOW WITH A MORE ZONAL LOOK. CURRENTLY OFF PAC COAST...WILL HAVE TO SEE IF SUBSEQUENT MODEL RUNS PERSIST. NEXT ISSUE HOLDS OFF UNTIL THURSDAY. FASTER AND MORE AGGRESSIVE GFS MAINTAINS RAIN AFTER 12Z...ECMWF HOLDING OFF UNTIL AFTER 18Z. TEND TO LIKE THE ECMWF AS THE NAM/WRF IS ALSO COMING IN ON THE SIDE OF THE SLOWER SOLN.

THE STRONGEST STORM APPROACHING THE AREA IS EXPECTED TO AFFECT SPI BY 0630Z AND DEC BY 0745Z...IF IT HOLDS TOGETHER. STRONG WINDS WOULD BE THE MAIN HAZARD...WITH HAIL POSSIBLE. WINDS BEHIND THE FRONT ARE LOOKING STRONGER THAN PREVIOUSLY FORECAST. WE COULD SEE WINDS OVER 30 KT AT ALL TAF SITES BY 12Z- 15Z...ESPECIALLY INCREASING AS MIXING EXTENDS INTO THE LOWER TROPOSPHERE. MVFR CLOUDS MAY LINGER THROUGH MUCH OF THE DAY...BUT PRECIP SHOULD DIMINISH BY 17Z-18Z.
