PREV DISCUSSION... /ISSUED 625 AM EST TUE FEB 9 2016/

SHORT TERM /TODAY THROUGH WEDNESDAY/...
HAVE YET TO SEE MUCH IN THE WAY OF ACCUMULATING SNOWFALL ACROSS THE
AREA ALTHOUGH ISOLATED TO SCATTERED FLURRIES AND LIGHT SNOW SHOWERS
CONTINUE ACROSS THE NORTHWESTERN HALF OF THE AREA. STILL LOOKING FOR
AN INCREASE IN COVERAGE OF SNOW SHOWERS TODAY INTO THIS EVENING AS
THE NEXT SHORT WAVE ROTATES THROUGH THE AREA. THE REMAINDER OF THE
FORECAST PERIOD SHOULD SEE MOSTLY FLURRIES RETREATING NORTH AS THE
UPPER TROUGH SHIFTS SLIGHTLY NORTH AND EAST OF THE STATE AND COLD
ADVECTION AND OROGRAPHIC EFFECTS DOMINATE. SNOWFALL TOTALS ARE NOT
NOTICEABLY CHANGED WITH THIS FORECAST CYCLE AND NO CHANGES ARE
PLANNED FOR THE WINTER WEATHER ADVISORY. WINDS INCREASE ONCE AGAIN
TODAY THROUGH WEDNESDAY AND COMBINED WITH THE COLD TEMPERATURES IN
PLACE ACROSS THE REGION WILL RESULT IN ADVISORY LEVEL WIND CHILL
VALUES IN THE NORTHEAST GEORGIA AREA SO NO PLANS TO ALTER THE WIND
CHILL ADVISORY EITHER AT THIS TIME.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
WEAK BOUNDARY OVER THE MID MISSISSIPPI RIVER VALLEY IS EXPECTED TO
DROP SOUTH ACROSS THE SOUTHEAST STATES WEDNESDAY AND THURSDAY. BY
LATE THURSDAY...THE OLD BOUNDARY WILL BECOME NEARLY STATIONARY
ACROSS CENTRAL GA. A WAVE OF LOW PRESSURE WILL MOVE EAST ALONG THE
BOUNDARY ON FRIDAY. IN PREVIOUS MODEL RUNS...SOME VERY LOW POPS/LIGHT
PRECIP WAS BEING PRODUCED WITH THIS SYSTEM. THE LATEST RUNS HAVE
REMOVED A GOOD DEAL OF THE MEASURABLE PRECIP/POPS. SO HAVE FOLLOWED
SUIT AND REMOVED THE SLIGHT POPS IN THE FORECAST FOR THIS PERIOD.

BEHIND THIS LOW PRESSURE SYSTEM...HIGH PRESSURE BUILDS IN FOR THE
WEEKEND.

A COLD FRONT WILL BEGIN TO MOVE INTO THE LOWER MISSISSIPPI RIVER
VALLEY EARLY MONDAY AND CONTINUE EASTWARD THROUGH THE EARLY WEEK.
POPS SHOULD BEGIN TO INCREASE ACROSS THE CWFA INTO TUESDAY.
CURRENTLY...THERE COULD BE SOME PTYPE ISSUES AS THE SYSTEM MOVES
THROUGH. HOWEVER...THE FORECAST WILL LIKELY CHANGE THIS FAR OUT.
