Posted by JAC on 1/22/2010, 12:53 pm








DAY 3 CONVECTIVE OUTLOOK  
  NWS STORM PREDICTION CENTER NORMAN OK
  0129 AM CST FRI JAN 22 2010
 
  VALID 241200Z - 251200Z
 
  ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE ERN GULF
  COAST STATES AND CAROLINAS...
 
  ...CAROLINAS/ERN GULF COAST STATES...
  A LARGE UPPER-LEVEL LOW IS FORECAST TO CONTINUE DEEPENING ACROSS THE
  UPPER MIDWEST SUNDAY AS A POWERFUL MID-LEVEL JET MOVES NEWD ACROSS
  THE APPALACHIAN MTNS. AN IMPRESSIVE 55 TO 65 LOW-LEVEL JET IS
  FORECAST TO BE IN PLACE FROM GA NEWD INTO THE MID-ATLANTIC. A LINE
  OF STORMS SHOULD BE ONGOING SUNDAY MORNING ACROSS THE CNTRL GULF
  COAST STATES WITH THE LINE MOVING EWD INTO WRN GA AND THE CAROLINAS
  SUNDAY AFTERNOON. THE NAM AND GFS SOLUTIONS DIFFER ON THE PLACEMENT
  OF THE LINE WITH THE NAM SLOWER AND FURTHER WEST.

AM FAVORING THE GFS SOLUTION WHICH DEVELOPS A WELL-FORMED SQUALL-LINE BY LATE SUNDAY AFTERNOON FROM CNTRL NC SWWD INTO CNTRL GA ALONG THE WEST EDGE OF THE LOW-LEVEL JET.

FORECAST SOUNDINGS ALONG THE ENTIRE LENGTH OF THE SLIGHT RISK AREA SHOW VERY STRONG DEEP LAYER SHEAR...LOW-LEVEL WINDS AROUND 60 KT AND SFC DEWPOINTS IN THE LOWER 60S F.

THIS COMBINATION OF PARAMETERS SUGGEST CONDITIONS WILL BE FAVORABLE FOR DAMAGING WIND GUSTS WITH THE MORE INTENSE LINE-SEGMENTS.
