Area forecast discussion, Dec 31, 6:52 AM CST, 4 hours before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE LITTLE ROCK AR 652 AM CST FRI DEC 31 2010 .UPDATE... HAVE JUST SENT THE FIRST...BUT PROBABLY NOT THE LAST...UPDATE FOR THE MORNING PACKAGE. INCOMING DATA IS SHOWING THAT SEVERE STORMS ARE AN INCREASING POSSIBILITY OVER THE ENTIRE AREA...AS UPPER LEVEL DIFFLUENCE AND LOW LEVEL SHEAR...AS WELL AS CAPE CONTINUE TO INCREASE. HAVE ADJUSTED THE FORECAST TO INCLUDE THE POSSIBILITY OF SEVERE STORMS OVER THE ENTIRE AREA...UPPED POPS A CATEGORY IN MOST PLACES...AND HAVE EVEN INCREASED EXPECTED MAX TEMPS IN SOME SPOTS DUE TO STRONG WARM ADVECTION OCCURRING. TO ALL THOSE INTERESTED...WE WILL BE RELEASING A 17Z UPPER AIR SOUNDING IN SUPPORT OF SEVERE WEATHER OPERATIONS. && .PREV DISCUSSION... /ISSUED 529 AM CST FRI DEC 31 2010/ AVIATION... AT 11Z THE COLD FRONT AND ASSOC CONVECTION WAS LOCATED IN EASTERN OKLAHOMA. BASED ON SFC OBS AND RECENT RADAR TRENDS/LOOPS...IT APPEARS THE SPEED OF THIS FRONT WILL GIVE TERMINALS ROUGHLY 3HRS OF -TSRA CONDITIOSN TODAY. AS SUCH I HAVE -TSRA WITH MVFR CIGS AND GUSTY SFC WINDS OF 20-30KT AT KHRO BETWEEN 15-18Z...AT KBPK...KHOT AND KLIT BETWEEN 17-20Z...AND FINALLY 18-21Z FOR KPBF AND KLLQ. TIMING COULD BE AN ISSUE WITH KPBF AND KLLQ AS THERE IS SOME INDICATION THAT THE FRONT WILL SLOW AS IT MAKES IT INTO ERN/SERN ARKANSAS THIS AFTERNOON...SO THIS WILL HAVE TO BE MONITORED BY THE DAY SHIFT. BEHIND THE FRONT CIGS WILL QUICKLY TRANSITION TO VFR LEVELS AND WINDS WILL VEER AROUND TO WESTERLY. SFC PRESSURE GRADIENTS SHOULD NOT BE TOO STRONG BEHIND THE FRONT SO DO NOT EXPECT GUSTY WEST WINDS AFTER FROPA. && .LZK WATCHES/WARNINGS/ADVISORIES... LAKE WIND ADVISORY UNTIL 6 PM CST THIS EVENING FOR BAXTER-BOONE- FULTON-INDEPENDENCE-IZARD-JACKSON-MARION-NEWTON-SEARCY-SHARP- STONE. && 57

ISOLATED TO SCATTERED THUNDERSTORMS ARE EXPECTED ALONG AND JUST AHEAD OF THE FRONT. STORMS MAY POSSIBLY INCREASE IN COVERAGE AS THE DAY PROGRESSES AND MORE HEATING OCCURS...ESPECIALLY IN THE SOUTH AND EASTERN PARTS OF THE FORECAST AREA. SOME STORMS THAT DEVELOP TODAY COULD BECOME SEVERE. THE CHANCE OF SEVERE WEATHER WILL BE THE HIGHEST AS THE FRONT NEARS THE MISSISSIPPI RIVER DURING THE LATE AFTERNOON OR EARLY EVENING HOURS. DUE TO A LARGE AMOUNT OF WIND ENERGY SURROUNDING THE SYSTEM...AND WINDS TURNING WITH HEIGHT...ANY STORMS THAT BECOME SEVERE WILL BE CAPABLE OF PRODUCING STRONG TO DAMAGING WINDS ALONG WITH ISOLATED TORNADOES. ARKANSAS RESIDENTS SHOULD MONITOR WEATHER FORECASTS FOR FUTURE UPDATES ON THIS POTENTIAL SEVERE WEATHER SITUATION. THE FRONT WILL EXIT EASTERN ARKANSAS LATE THIS EVENING. DRIER AND COOLER AIR WILL FOLLOW THE FRONT THIS WEEKEND. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY NO SEVERE WEATHER IS EXPECTED. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION COULD BE REQUIRED...ESPECIALLY FOR PORTIONS OF SOUTHEASTERN ARKANSAS. && VISIT NWS LITTLE ROCK ON THE WEB. GO TO HTTP://WEATHER.GOV AND CLICK ON CENTRAL ARKANSAS. 64
