.PREV DISCUSSION...ISSUED 246 AM CST THU FEB 1 2007
ROUND ONE OF THE WINTER WEATHER IS BEGINNING TO MOVE AWAY FROM THE
FORECAST AREA THIS MORNING. LOCAL RADAR SHOWS THE MAIN PRECIP
EXTENDING SOUTH OF A LINE FROM TUPELO TO CHARLESTON.
ELSEWHERE...PRECIP IS VERY LIGHT AND BECOMING PATCHY. GFS/NAM APPEAR
TO HAVE A VERY GOOD HANDLE ON THE FORECAST FOR TODAY. WILL
DISCONTINUE ADVISORIES THIS MORNING EXCEPT WHERE THE MAIN PRECIP
BAND IS CURRENTLY AT. MODELS SHOW THIS BAND OF MOISTURE PERSISTING
IN THIS AREA UNTIL LATE MORNING. WITH TEMPERATURES THERE HOVERING
AROUND THE FREEZING POINT...SOME LIGHT ICING REMAINS POSSIBLE.
ELSEWHERE...ADDITIONAL PRECIP THIS MORNING SHOULD BE INSIGNIFICANT.
HOWEVER...REPORTS OF ACCIDENTS FROM ICED ROADWAYS FROM EARLIER
PRECIP CONTINUE TO ROLL IN SO MOTORISTS SHOULD CONTINUE TO BE ALERT
THIS MORNING ACROSS THE ENTIRE REGION. ROUND TWO IS EXPECTED TO MOVE
INTO THE REGION DURING THE AFTERNOON AND EXIT THE REGION THIS
EVENING. THIS NEXT ROUND IS ASSOCIATED WITH ANOTHER SHORTWAVE TROUGH
MOVING THROUGH THE AREA AND A DEVELOPING 180KT JET STREAK. NAM
SOUNDINGS SHOW THAT THE RAIN/SNOW LINE WILL FALL ROUGHLY ALONG
INTERSTATE 40 THIS AFTERNOON. DO EXPECT THAT LOCATIONS ALONG
INTERSTATE 40 WILL GET ABOVE FREEZING BEFORE THIS PRECIP
BEGINS...BUT THAT THE TEMP WILL WET BULB DOWN TO NEAR THE FREEZING
POINT DURING THE AFTERNOON AND INTO THE EVENING. QPF AMOUNTS ON BOTH
THE GFS/NAM ARE AROUND 0.10-0.20 INCHES. ASSUMING A 10-1 RATIO WHICH
SHOULD WORK OUT ABOUT RIGHT FOR THIS SITUATION...1 TO 2 INCHES ARE
POSSIBLE ALONG THE I-40 CORRIDOR AND NORTHWARD. AS A RESULT...A SNOW
ADVISORY WILL BE IN EFFECT FOR THIS AFTERNOON FOR THIS AREA.
THE MORE SIGNIFICANT PRECIP SHOULD END ACROSS THE ENTIRE REGION
THIS EVENING AS THIS SHORTWAVE MOVES EASTWARD. SOME LIGHT PRECIP
IN THE WAKE OF THE SYSTEM IS POSSIBLE BUT ACCUMULATIONS SHOULD BE
INSIGNIFICANT.
ON FRIDAY...LOW CLOUDS WILL STICK AROUND FOR THE ENTIRE DAY. A
CHANCE OF FLURRIES/SPRINKLES WILL BE POSSIBLE AS A WEAKENING
SHORTWAVE MOVES THROUGH THE REGION. PRECIP IS EXPECTED TO BE MOST
NOTICEABLE OVER OKLAHOMA BUT SHOULD DIMINISH SIGNIFICANTLY AS IT
MOVES ACROSS ARKANSAS.
EXPECT CLOUDS TO GRADUALLY BREAK UP ON SATURDAY. HOWEVER...MUCH
BELOW NORMAL TEMPERATURES ARE EXPECTED TO PERSIST THROUGH THE
REMAINDER OF THE FORECAST AS UPPER TROUGH SETTLES OVER THE EASTERN
U.S. NO OTHER SIGNIFICANT WEATHER SYSTEMS APPEAR IN THE MODELS AT
THIS POINT...THUS A DRY FORECAST.
