.SHORT TERM /TODAY THROUGH FRIDAY/...
KCCX IS BACK IN OPERATION WITH SOME NEW PARTS...THANKS TO SOME
REAL LATE NIGHT WORK BY OUR TECHS.

BUSY SHIFT. LOTS OF FAST MOVING WEATHER SYSTEMS TO DEAL WITH.
FIRST THING...FAST MOVING IMPULSE WILL RIDE THROUGH THE NRN PART
OF CWA DURING THE AFTN TODAY...BRINGING INSTABILITY IN THE AFTN
AND THEN A GOOD COLD PUNCH FOR TONIGHT. THIS WILL CREATE SNOW
SHOWERS AND HEAVIER SQUALLS FOR LATE THIS MORNING INTO THE AFTN
IN THE WEST...AND FOR THE AFTN INTO EARLY EVENING OVER THE
EASTERN ZONES. THE LOWER SUSQ COULD GET BY WITHOUT ANY
ACCUMS...BUT THEY COULD STILL SEE A SNOW SHOWER WITH LOTS OF LLVL
UP-OMEGAS/UPLIFT. WILL HOLD THE SE IN CHC RANGE...BUT BUMP
EVERYONE ELSE UP TO LIKELIES AND CATG POPS. ACCUMS SHOULD BE
GENERALLY 1 TO 2 INCHES WITH MOST ACCUMS TO THE WEST OF RTE 220
AND NORTH OF RTE 322. A FEW SPOTS WILL SEE 3 INCHES BY
SUNSET...ESP THE NWRN ZNS AND LAURELS...AS THE COLD AIR AND WEST
WIND BRING LAKE EFFECT DYNAMICS AND UPSLOPE MOIST FLOW INTO PLAY
LATER TODAY. WILL GO 2-3 NW AND IN THE LAURELS WITH GOOD UPSLOPE
AND MSTR...AND POST ADVISORIES FOR BOTH AREAS...LES ADVSRY IN N
AND SNOW ADVSRY IN LAURELS. THE ADVISORIES WILL RUN THROUGH WED
MORNING...AS THE FLUFFY SNOW WILL BUILD UP ANOTHER 2-4 INCHES IN
THOSE FAVORED AREAS OVERNIGHT AND EARLY WED.

MAX TEMPS WILL BE COOLER THAN NORMS TODAY AND WED...WITH NEAR
NORMAL MINS TONIGHT UNDER CLOUDS AND GOOD MIXING FROM COLD
ADVECTIVE WINDS. THE SHSN AND FLURRIES WILL TAPER OFF WED
MORNING...WITH LITTLE ADDITIONAL ACCUMS AFTER 10 AM.

A BRIEF RESPITE LATER WED INTO THURSDAY MORNING...BUT FAST FLOW
BRINGS WHAT COULD BE THE MOST SIGNIFICANT AND WIDESPREAD SNOWFALL
OF THIS ANEMIC WINTER SEASON. THIS LOOKS LIKE IT WILL HAPPEN JUST
IN TIME FOR THE GROUNDHOG TO HAVE TO DIG THROUGH SOME FRESH SNOW
ON FRIDAY MORNING. MY GUESS...HE/LL SEE THE OLD SHADOW. I WILL
TAKE A FIRST STEP IN THE FORECAST...THOUGH AND UP POPS ABOUT 20
PCT...MAKING LIKELIES FOR THURS NIGHT. WILL CALL IT ALL SNOW FOR
MOST LOCATIONS FOR NOW...ALTHOUGH ENOUGH WARM AIR MAY WORK IN
ALOFT IN THE FAR SE TO MAKE A LITTLE MIX WITH SLEET OR EVEN A SPOT
OF FZRA. BUT...AGAIN AS A FIRST STEP...WILL KEEP IT JUST RA/SN
LIKELY THERE.

THIS GROUNDHOG DAY SYSTEM IS MOVING VERY FAST...AND DEVELOPMENT DOES
NOT APPEAR TO OCCUR UNTIL AFTER IT IS OF TO OUR EAST. THE WSW FLOW
ALOFT IS RATHER POTENT. WILL THEREFORE SEE THE PRECIP LIMITED IN
TIME...MAYBE 12-16 HRS THURS NITE AND EARLY FRI MORNING. BUT...THAT
SHOULD BE ENOUGH TO WHITEN MOST IF NOT ALL THE CWA. TOO EARLY TO
PAINT ACCURATE ACCUMS...BUT YOU MAY NEED THE SHOVEL THIS TIME.
WILL START TO MENTION THIS SYSTEM IN THE HWO...AGAIN AS A FIRST
STEP.

&&

.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
DID NOT TOUCH THE GRIDS BEYOND FRI NIGHT...BUT THE REST OF THE
FCST PD LOOKS NORMALLY OR EVEN SUB-NORMALLY COLD. LAKE EFFECT WILL
DOMINATE THE FORECAST FOR THE REST OF THE PD...ALTHOUGH OCCASIONAL
