.DISCUSSION...
/302 AM CST SUN JAN 24 2010/

RAIN WILL DIMINISH FROM WEST TO EAST THIS MORNING AS LOW PRESSURE
CONTINUES TO PULL NORTHEAST TOWARD THE GREAT LAKES. TRAILING COLD
FRONT WILL PROGRESS EAST WITH FALLING TEMPERATURES EXPECTED THIS
AFTERNOON. STILL LOOKS LIKE A FEW SNOW SHOWERS WILL BE POSSIBLE
TONIGHT AND MONDAY AS THE LAST OF THE EMBEDDED SHORTWAVES IN THE
LARGER UPPER TROF ROTATES ACROSS THE REGION. LITTLE IF ANY SNOW
ACCUMULATION IS EXPECTED...BUT WITH THE INCREASED NORTHWEST WIND AND
COLDER TEMPERATURES IT WILL FEEL MORE LIKE WINTER AROUND HERE.

HIGH PRESSURE BUILDS ACROSS THE REGION MONDAY NIGHT AND TUESDAY
PROVIDING SEASONAL COLD WEATHER. MAYBE WE WILL FINALLY GET TO SEE
THE SUN TUESDAY AFTERNOON?

ATTENTION THEN TURNS TO A POTENT SOUTHERN STREAM SHORTWAVE/LOW THAT
WILL BE BARRELING ONSHORE ACROSS SOUTHERN CALIFORNIA TUESDAY NIGHT.
GFS ENSEMBLE MEAN/ECWMF/GEM ARE BEGINNING TO COME INTO ALIGNMENT
WITH THIS SYSTEM...WITH SURFACE LOW PRESSURE MOVING ACROSS THE
SOUTHERN CONUS...FROM TEXAS TO GEORGIA...ON THURSDAY AND FRIDAY.

AS THIS SYSTEM APPROACHES...A REINFORCING COLD FRONT WILL MOVE SOUTH
ACROSS MISSOURI AND ILLINOIS ON WEDNESDAY.

APPEARS A CLASSIC OVERRUNNING WINTER PRECIPITATION EVENT WILL TAKE
PLACE ACROSS THE SOUTHERN HALF OF THE CWA WEDNESDAY NIGHT AND
THURSDAY...WITH THE TYPICAL ARRAY OF PRECIPITATION TYPES FROM
RAIN/FREEZING RAIN ACROSS FAR SOUTHERN MISSOURI TO SNOW ALONG THE
INTERSTATE 70 CORRIDOR. PRECIPITATION TYPE WILL HIGHLY DEPEND ON HOW
FAR SOUTH AND DEEP THE ARCTIC AIR CAN BUILD.

SINCE THE EXPECTED TRACK OF THE LOW PRESSURE IS SO FAR SOUTH...THE
DRY AIR FACTOR WITH THE IMPINGING HIGH PRESSURE WILL DEFINITELY COME
INTO PLAY WITH THIS EVENT. WOULD EXPECT A VERY SHARP GRADIENT IN
SNOWFALL ALONG THE NORTHERN EDGE...WHICH LOOKS TO ALIGN WITH
INTERSTATE 70 AT THIS TIME.

I HAVE INTRODUCED FREEZING RAIN AND SLEET TO THE FORECAST
WEDNESDAY NIGHT AND THURSDAY...WITH PRECIPITATION TRENDING TOWARD
ALL SNOW THURSDAY NIGHT AND FRIDAY AS THE COLD AIR DEEPENS OVER
THE REGION IN THE WAKE OF THE SURFACE LOW/TROF.

THERE IS NO DOUBT WE WILL CONTINUE TO SEE DISCREPANCIES IN THE SPEED
AND TRACK OF THIS STORM SYSTEM IN THE DAYS AHEAD...BUT GIVEN THE
POTENTIAL IMPACT ACROSS THE SOUTHERN HALF OF THE CWA I PLAN ON
MENTIONING A POTENTIAL WINTER STORM IN THE HWO.

MORNING WAS DUE TO THE DRY SLOT DIRECTLY OVERHEAD AND A RETURN TO
IFR/MVFR CIGS IS EXPECTED AS THE DRY SLOT SHIFTS EWD AND CLDS WRAP
