SOUTHWEST...CENTRAL LOUISIANA AND SOUTHEAST TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
229 AM CST SAT JAN 2 1999

A MAJOR WINTER STORM CREATING HAVOC ACROSS THE LCH CWA THIS MORNING...
WITH NUMEROUS REPORTS OF DAMAGE AND POSSIBLE TORNADIC DAMAGE. THE LINE
OF STRONG-SEVERE THUNDERSTORMS HAS PUSHED ACROSS THE SABINE RIVER WITH
LEWP/BOW FEATURES INDICATED ON THE LCH 88D. MOVEMENT OF THE LINE IS TO
THE EAST AT 35 KNOTS...WITH INDIVIDUAL CELLS MOVING NORTHEAST AT 4O
KTS. OVER THE LAST HOUR...LCH VWP PROFILE HAS BECOME MORE
UNIDIRECTIONAL WITH STRONG STORM INFLOW OF 30 KTS..SUGGESTIVE OF THE
SYSTEM EVOLVING INTO A LINEAR MCS.

MODELS IN GENERAL AGREEMENT WITH SWINGING THIS MAJOR STORM NORTHEAST
INTO THE TENNESSEE AND OHIO VALLEYS IN 24H...AND NORTHEAST INTO THE
EASTERN GREAT LAKES IN 48H. THE LONG WAVE TROUGH RESPONSIBLE FOR THIS
SYSTEM WILL POSITION ITSELF OVER THE CENTRAL U.S. THROUGH THE FORECAST
PERIOD...SENDING AN ARCTIC AIRMASS SOUTHWARD TO THE GULF COAST.
MASSIVE COLD AIR ADVECTION WILL TAKE PLACE THE NEXT 48H WITH 1000
TO 500 THICKNESSES DOWN TO 546 DM AT THE COAST BY 00Z SUN AND 534 DM
BY 00Z MON...AS INDICATED BY THE PREFERRED ETA SOLUTION. ALL MODELS
INDICATE CONDITIONS DRYING OUT TODAY...WITH NO LOW-LEVEL STRATOCUMULUS
FIELD FORECAST. STRONG SUBSIDENCE COUPLED WITH THE RAPID NORTHWARD
MOVEMENT OF THE LOW SUPPORTS THIS ARGUMENT. FRONTAL PASSAGE WILL BE
COMPROMISED BETWEEN THE ETA AND NGM SOLUTIONS BASED ON ONGOING
TRENDS...11Z BPT/LCH...12Z AEX...AND 13Z FOR LFT. PRE-FRONTAL TROUGH
AHEAD OF THE FRONT HAS ALREADY SHIFTED WINDS TO THE SOUTHWEST AT
BPT...LIKEWISE EXPECTED AT LCH IN THE NEXT HOUR. DECREASING
CLOUDINESS...WINDY AND TURNING COLDER WILL WORK FOR THE ZONES TODAY.
LOW POPS WILL NEED TO BE CARRIED ACROSS SOUTHEAST TEXAS AND SOUTHWEST
LA THROUGH THROUGH THE MORNING HOURS...WITH HIGHER POPS ACROSS THE
EASTERN ZONES...BUT ALSO FOR THE MORNING. WIND ADVISORY RECOMMENDED
FOR THE ENTIRE CWA WITH THE A STRONG PRESSURE GRADIENT BETWEEN THE
DEPARTING LOW AND HIGH PRESSURE MOVING SOUTHWARD ACROSS THE PLAINS.
MOSTLY CLEAR/SUNNY SKIES WILL PREVAIL THROUGH MUCH OF THE FORECAST
PERIOD...WITH SOME HIGH CLOUDINESS MOVING IN LATE SUNDAY AS A
DISTURBANCE IN THE NORTHWEST FLOW APPROACHES.

A BLEND OF THE NGM AND FAN GUIDANCES LOOKS TO BE THE BEST APPROACH
FOR THE TEMPERATURE FORECAST.
