If we can get a -nao I feel very good we cash in.

 

It's been showing up in the lr in various forms for a week. Mostly east based and transient for the most part. It's crazy when you look @ the graph from dec 1st through today. Never above or below 1sd except for a small period in the middle of dec when it was a good bit negative. The pac killed it though. It was a torch. 

 

Now it's firmly in place from hr 300 through the end of the run on the 18z gfs. Right smack dab over the middle of gl. And it doesn't run away like a scared mouse either. 

 

 

 

 

If we can't get a damn miller a to run the coast with split flow, +pna, pv nearby, and a freekin 540dm ridge over gl then I'm telling you, someone sold our souls without asking.

LWX discussion from early morning, FWIW

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...

HIPRES IS FCST TO SHIFT OFF THE COAST SUN NGT AS AN ORGANIZED LOW

MOVES NEWD INTO THE UPPER MIDWEST. BROAD SLY FLOW IN BETWEEN BOTH

SYSTEMS WILL DRAW WARM/MOIST AIR UP THE ERN SEABOARD. MOST GUIDANCE

PRINTS OUT LIGHT QPF LATE SUN NGT INTO MON. WHILE TEMPS ALOFT

QUICKLY RISE ABOVE FREEZING PRIOR PRECIP STARTING...A WEDGE OF COLD

AIR AT THE SFC WILL TAKE LONGER TO ERODE. A WINTRY MIX IS POSSIBLE

WITH THIS SETUP AT THE ONSET BEFORE THE CHANGEOVER TO RAIN SOMETIME

DURING THE DAY MON. IN-SITU CAD MAY DEVELOP MON AND LAST LONGER

THAN MODELS INDICATE...SO COLDER TEMPS AND CLOUDIER CONDITIONS MAY

PERSIST ERY NEXT WEEK.

FCST UNCERTAINTY DECREASES CONSIDERABLY FOR THE MIDDLE OF NEXT WEEK.

WILL NEED TO WATCH FOR A WAVE OF LOPRES DEVELOPING ALONG A STALLED

FRONTAL BOUNDARY LIKE THE 12Z GFS AND SOME ITS ENSEMBLE MEMBERS

SHOW. 00Z ECMWF ALSO ON BOARD W/ THIS SOLN...BUT IT KEEP PCPN S OF
