Massive blizzard expected to hit the Midwest this week...Iowa and Wisconsin should be hardest hit and it could be devastating in those areas.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
500 AM PST SUN DEC 6 2009

.DISCUSSION...
VERY INTERESTING PATTERN SETTING UP FOR THE REGION LATER TONIGHT AND
MONDAY. COLD AND DRY AIRMASS ORIGINATING FROM WESTERN CANADA HAS
SETTLED IN ACROSS THE INTERIOR OF NORTHERN CALIFORNIA IN THE WAKE OF
THE MAINLY DRY COLD FRONT THAT SWEPT SOUTHWARD THROUGH THE REGION ON
SATURDAY. THE MODERATELY STRONG NORTHERLY GRADIENTS THAT DEVELOPED
SATURDAY WEAKENED OVERNIGHT ALLOWING THE AIRMASS OVER THE VALLEY TO
DECOUPLE RESULTING IN LIGHT WINDS MOST AREAS AND COLD TEMPERATURES.
SOME FROST WILL BE POSSIBLE THIS MORNING IN THE VALLEY WHERE LIGHTER
WINDS OCCURRED...MAINLY ALONG THE EAST SIDE...BUT DEWPOINTS REMAIN
TOO LOW MOST OTHER AREAS (MID TO UPPER 20S).

SATELLITE IMAGERY SHOWS THE NEXT UPSTREAM SYSTEM OVER THE PACIFIC
NORTHWEST MOVING SOUTHWARD. THIS SYSTEM WILL USHER AN EVEN COLDER
AIRMASS SOUTHWARD INTO THE REGION LATER TONIGHT AND MONDAY WITH SNOW
LEVELS LOWERING TO THE VALLEY FLOOR AS 850 MB TEMPS LOWER TO -4 TO
-5 C AND 1000/500 MB THICKNESS LOWERS TO 522 TO 525 DM ACROSS THE
REGION. NAM AND GFS CONTINUE TO FORECAST STRONG LOW-LEVEL
FRONTOGENESIS TO OCCUR LATE TONIGHT AND MONDAY AHEAD OF A WAVE THAT
DEVELOPS ALONG THE COLD FRONT AS IT SWEEPS SOUTH. STRONG UPWARD
VERTICAL MOTION IS FOCUSED OVER THE I-80 AND HIGHWAY 50 CORRIDOR...
AND THAT/S WHERE THE HEAVIEST QPF IS EXPECTED. NAM CROSS-SECTIONS
FOR KSAC INDICATING POTENTIAL FOR SIGNIFICANT SNOWFALL IN THE
SACRAMENTO AREA LATE TONIGHT AND MONDAY WITH OVERLAP OF STRONG OMEGA
(-30 UB/SEC) WITH A THICK REGION OF DENDRITIC SNOW GROWTH. IF THIS
PANS OUT...WE COULD SEE RECORD SNOWFALL FOR THE AREA (24 HOUR RECORD
SNOWFALL FOR DOWNTOWN SACRAMENTO IS 3.5 INCHES SET ON JANUARY 4TH
AND 5TH 1888). STEEP LAPSE RATES AND SOME OROGRAPHIC CONTRIBUTION
WILL ENHANCE SNOW AMOUNTS OVER THE FOOTHILLS AND WEST SLOPES OF THE
NORTHERN SIERRA NEVADA.

PDS Winter Storm Warning/Blizzard Warning, anyone?

[srainhoutx]

Very possible. Not to take away from anything from the "local Winter Wether threads" discussions, I started a "general discussion" Topic for those that may want to participate and perhaps learn as our "pros" and other knowledgeable enthusiasts are posting much more than usual. Since many regions will be involved with this Major Winter Storm Event, it will be very interesting to watch unfold for many folks.

PDS Winter Storm Warning/Blizzard Warning, anyone?

Those would be totally unofficial, since winter watches and warnings are issued by local offices, not the SPC.
