AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
1026 PM CST THU DEC 5 2013

.DISCUSSION...

MADE SOME ADJUSTMENTS TO THE ZONES. INCREASED THE ICE ACCUMULATIONS
FOR WITHIN THE ICE STORM WARNING AREAS. TWEAKED THE WINDS AND
DEW POINTS. COLD AIR CONTINUED TO SPILL SOUTHEAST INTO THE FOUR
STATE REGION WITH THE SHALLOW AIR MOVING ACROSS NORTHEAST AND
NORTHEAST TEXAS THIS EVENING. THE COLDER AIR WILL BE SLOWER TO
MOVE THROUGH THE OUACHITA/S AND ACROSS REMAINING PARTS OF THE REGION.
ICE ALREADY GLAZING ELEVATED OBJECTS SUCH AS BRIDGES...OVERPASSES...
TREES...AND POWER LINES WHERE TEMPERATURES ARE AT 32 DEGREES OR LOWER.
THERE MAY BE SOME SLEET MIXED IN WHERE THE READINGS DROP INTO THE
LOWER TO MIDDLE TWENTIES NORTHWEST INTERSTATE 30.

&&

.AVIATION...

COMPLEX AND MESSY FCST FOR THE 06Z TAFS. PRECIP EXPECTED TO
GRADUALLY INCREASE IN COVERAGE THROUGHOUT THE EARLY MORNING HOURS.
PRIMARY CONCERN IS POTENTIAL FOR FZRA. AREAS MOST LIKELY TO
EXPERIENCE FZRA DURING THE TAF PERIOD WILL BE ALONG AND NORTH OF A
LINE FROM KJSO-KGGG-KDNT-KELD. SOME OF THESE LOCATIONS ARE STILL
ABOVE FREEZING BUT AS WET BULB EFFECTS COOL TEMPS IN THE LOW LVLS
PRECIP SHOULD TRANSITION TO FZRA. GREATEST ICE
ACCUMULATIONS...POSSIBLY AS MUCH AS BETWEEN A HALF INCH AND AN
INCH...ARE EXPECTED TO BE ALONG AND NORTH OF I-30. FARTHER S AND
E...TEMPS SHOULD STAY HIGH ENOUGH TO KEEP RAIN AS LIQUID. A MIX OF
MVFR/IFR CONDITIONS WILL CONTINUE ALTHOUGH MOST TERMINALS SHOULD BE
IFR AS PRECIP BECOMES MORE WIDESPREAD. PRECIP SHOULD GRADUALLY COME
TO AN END FRIDAY AFTERNOON BUT MVFR CIGS WILL PERSIST. /09/
