.UPDATE...

.DISCUSSION...
/ISSUED 241 PM CST SAT JAN 3 2015/

CURRENT WATER VAPOR IMAGERY SHOWS AN UPPER LEVEL LOW OVER THE TEXAS
PANHANDLE...WHILE SURFACE ANALYSIS DEPICTS THE SURFACE LOW OVER
SOUTHERN ILLINOIS. A COLD FRONT EXTENDS SOUTHWARD FROM THIS LOW AND
WAS JUST WEST OF THE MISSISSIPPI RIVER ATTM. MEANWHILE...A WARM
FRONT EXTENDED FROM THE LOW...SOUTHEASTWARD THROUGH MUSCLE
SHOALS...BIRMINGHAM...AND INTO SOUTHWEST GEORGIA. STRONG SOUTHERLY
FLOW HAS ADVECTED WARM AND MOIST GULF AIR INTO THE MISSISSIPPI AND
LOWER TENNESSEE VALLEY REGIONS OVER THE LAST SEVERAL HOURS...WITH
MANY LOCATIONS REACHING INTO THE MID TO UPPER 60S...WHICH IS ROUGHLY
20+ DEGREES WARMER THAN WHERE WE WERE AT THIS TIME YESTERDAY.

NOT MUCH HAS CHANGED...OVERALL...WITH THE SETUP FOR THIS EVENING AND
OVERNIGHT. THE AFOREMENTIONED COLD FRONT WILL SLOWLY TRACK
EASTWARD...AS THE UPPER LEVEL LOW MOVES TO THE NORTHEAST. AN AREA OF
RAIN WILL CONTINUE TO MOVE EASTWARD AHEAD OF THIS FRONT...WITH THE
MAIN LINE ENTERING THE WESTERN PORTION OF THE FORECAST AREA AROUND
00Z. ALTHOUGH WE ARE VERY MOIST AND HAVE BEEN ABLE TO WARM UP QUITE
A BIT DESPITE EXTENSIVE CLOUD COVER...THE OVERALL SEVERE THREAT
STILL APPEARS TO BE MINIMAL FOR THE FORECAST AREA. ONE OF THE MAIN
LIMITING FACTOR CONTINUES TO BE THE CAPPING INVERSION JUST OFF OF THE
SURFACE. BECAUSE OF THE WARM LAYER ALOFT...SURFACE BASED INSTABILITY
WILL BE HARD TO COME BY...ALTHOUGH GUIDANCE IS FAIRLY CONSISTENT
WITH BRINGING IN A NARROW BAND OF INSTABILITY JUST AHEAD OF THE COLD
FRONT. LOW LEVEL WIND SHEAR CERTAINLY WILL NOT BE A PROBLEM...THANKS
TO THE 50KT LOW LEVEL JET MOVING ACROSS REGION...AS THE SURFACE LOW
MOVES EAST ACROSS THE GREAT LAKES REGION. HOWEVER...FROM THE LATEST
GUIDANCE...THE INSTABILITY AND SHEAR MAY NOT OCCUR DURING THE SAME
TIME. NEVERTHELESS...IT WILL CERTAINLY BE SOMETHING TO WATCH CLOSELY.
IT SHOULD BE NOTED THAT...ALTHOUGH THE INSTABILITY WILL BE
SHALLOW...OUR LCL HEIGHTS ARE QUIET LOW...SO THIS COMBINED WITH THE
WIND SHEAR WILL POSE THE THREAT FOR AN ISOLATED BRIEF SPIN UP ALONG
THE MAIN LINE...WHICH SHOULD END AROUND MIDNIGHT.

THE MORE WIDESPREAD THREAT WITH THIS SYSTEM CONTINUES TO BE THE
POSSIBILITY OF FLOODING. MANY LOCATIONS HAVE SEEN UP TO 3/4 INCH OF
RAIN OVER THE LAST 24 HOURS...IN ADDITION TO QUITE A BIT OF RAINFALL
THAT FELL WITH THE LAST SYSTEM. THIS HAS CREATED VERY SATURATED
GROUND CONDITIONS ACROSS MUCH OF THE AREA. AN ADDITIONAL 1 TO 2
INCHES IS CERTAINLY POSSIBLE AS THE AREA OF RAIN MOVES THROUGH...WITH
GUIDANCE SUGGESTING THE TRAINING OF MODERATE RAIN...ESPECIALLY
ACROSS THE WEST. GIVEN THIS...WILL CONTINUE THE FLASH FLOOD WATCH
BEGINNING AT 00Z...WITH THE HIGHER AMOUNTS OF QPF EXPECTED AFTER
SUNSET.

THE COLD FRONT SHOULD EXIT THE AREA BY 12Z SUNDAY...WITH ISOLATED
LIGHT RAIN POSSIBLE JUST BEHIND THE FRONT. COOLER TEMPERATURES WILL
FILTER IN BEHIND THE FRONT AS HIGH PRESSURE BUILDS INTO THE REGION.
ANOTHER SURFACE LOW WILL TRACK EASTWARD ACROSS THE GREAT LAKES
TUESDAY NIGHT...WITH A FAIRLY STRONG ARCTIC FRONT TRAILING SOUTHWARD
AND MOVING THROUGH THE FORECAST AREA BY 06Z WEDNESDAY. DUE TO THE
HIGH PRESSURE IN PLACE PRIOR TO THIS FRONT AND LACK OF MOISTURE...NO
PRECIPITATION IS FORECAST. STRONG HIGH PRESSURE WILL CONTINUE TO
BUILD IN BEHIND THIS REINFORCING COLD FRONT...WITH OUR COLDEST
TEMPERATURES OF THE SEASON POSSIBLE BY THURSDAY MORNING. FORECAST
LOWS ARE EXPECTED TO DROP INTO THE LOWER TEENS TO SINGLE DIGITS.
GIVEN THE STRENGTH OF THE HIGH...AND STRONG PRESSURE GRADIENT...WINDS
WILL STAY AROUND 10KTS...CREATING WIND CHILL VALUES BELOW 0 DEGREES
AND AS LOW AS -12 DEGREES IN SOME PLACES FOR SEVERAL HOURS BETWEEN
06Z AND 14Z THURSDAY. FORTUNATELY...THE ATMOSPHERE WILL BEGIN TO
MODIFY...WITH TEMPERATURE RETURNING TO NEAR NORMAL BY SATURDAY.

.AVIATION...
FOR 00Z TAFS...SHRA AND A FEW TSRA WERE OCCURRING ACROSS NW AL
ATTM...AHEAD OF A CDFNT ALONG THE MS RIVER. AS THE CDFNT MOVES EAST
TONIGHT EXPECT THE SHRA/TSRA TO SPREAD OVER THE ENTIRE CWA. THE CDFNT
WILL PASS THRU KMSL ARND 09Z AND KHSV BY 10Z...WITH THE PCPN
TAPERING OFF. MAINLY IFR CONDITIONS WILL BE POSSIBLE THRU 18Z. AFTER
18Z EXPECT MVFR CONDITIONS AT BOTH TAF SITES.
