NWS Jackson, KY wrote its last area forecast discussion before the first event at Feb 5, 7:15 PM EST, 1 hour 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 715 PM EST FRI FEB 5 2010 .SHORT TERM.../TONIGHT THROUGH SUNDAY NIGHT/ RAIN HAS BEEN ONGOING FOR MOST OF THE DAY. TOTALS AS OF MID AFTERNOON WERE RUNNING FROM AROUND AN INCH TO AN INCH AND A QUARTER MOST PLACES. THIS HAS BROUGHT ABOUT SUBSTANTIAL RISES ON SMALL STREAMS. HOWEVER...DUE TO THE PROLONGED NATURE OF THE EVENT WITH MOSTLY LIGHT MODERATE RAIN...THINK THAT IT WILL BE DIFFICULT TO GET SUBSTANTIAL FLOODING ON SMALL STREAMS...AS WATER HAS TIME TO RUN OFF AS FRESH RUNOFF ARRIVES. HOWEVER...LARGE CREEKS/RIVERS WILL NEED TO BE WATCHED AS THE WATER PILES UP IN THE BIGGER STREAMS. THE CULPRIT STORM SYSTEM IS COMPLEX. AT THE SURFACE THE LOW PRESSURE CENTER HAS BEEN DEVELOPING NORTH TOWARD KY FROM THE CENTRAL GULF COAST DURING THE DAY. HOWEVER...A SECOND LOW IS ALSO TAKING SHAPE ON THE EAST SIDE OF COLD AIR DAMMING ON THE EASTERN SIDE OF THE APPALACHIANS. THE EASTERN LOW WILL BECOME MORE DOMINANT AS COASTAL DEVELOPMENT KICKS IN TONIGHT. MEANWHILE...ALOFT...THE WESTERN LOW WILL BE MORE DOMINANT FOR A LONGER TIME. AS IT DRIFTS EAST...COLDER AIR WILL PIVOT AROUND IT. THIS WILL GET RID OF OUR WARM LAYER ALOFT...WHICH WILL PREVENT MELTING OF PRECIP ALOFT. AS THE SNOW TRIES TO REACH THE GROUND...EVENTUALLY THE SURFACE AIR WILL BE CHILLED TO AROUND THE FREEZING POINT. THE EXACT TIMING OF THIS WILL BE CRITICAL IN DETERMINING SNOW ACCUMULATIONS. THE 12Z RUNS OF THE WRF AND GFS WERE IN REASONABLY GOOD AGREEMENT FOR TEMPERATURE PROFILES AND PRECIP AMOUNTS...AND HAVE BASED THE FORECAST ON THIS. THE BEST ESTIMATE IS FOR 4 TO 6 INCHES NORTH OF AN OWINGSVILLE TO SANDY HOOK LINE...AND THIS AREA CONTINUES UNDER A WINTER STORM WARNING. THE FURTHER SOUTH...THE CHANGE TO SNOW AND DROP TO NEAR 32 DEG WILL TAKE LONGER...AND PRECIP WILL BE LIGHTER. THIS WILL KEEP ACCUMULATIONS LOWER...AND AN ADVISORY HAS BEEN USED. WOULD NOT BE SURPRISED IF SOME VALLEY LOCATIONS IN THE FAR SOUTH SEE LITTLE OR NO ACCUMULATION. SNOW WILL LINGER INTO SATURDAY...BUT WILL TAPER OFF AS THE UPPER LEVEL SYSTEM PULLS OUT TO THE EAST AND THE MID/UPPER LEVELS DRY OUT. SOME FLURRIES MAY PERSIST INTO SATURDAY NIGHT IF THE LINGERING LOW LEVEL MOISTURE IS DEEP ENOUGH TO HIT -10C AND ALLOW ICE CRYSTAL PRODUCTION. ITS CONCEIVABLE THAT FREEZING DRIZZLE COULD DEVELOP IF THE MOIST LAYER BECOMES TOO SHALLOW/WARM FOR ICE PRODUCTION. HOWEVER...THINK THAT THE PROBABILITY OF THIS IS STILL RATHER LOW AND HAVE NOT INCLUDED IT IN THE FORECAST. AS THE TEMPERATURE INVERSION CAPPING THE SURFACE COLD AIR MASS SINKS LOWER AND LOWER...OUR LOW CLOUDS WILL DECREASE OVERALL FROM LATE SATURDAY NIGHT INTO SUNDAY NIGHT. .LONG TERM.../MONDAY THROUGH FRIDAY/ THE FOCUS FOR THE LONG TERM FORECAST WILL DEAL WITH THE STORM SYSTEM EXPECTED MONDAY NIGHT THROUGH WEDNESDAY NIGHT. ON MONDAY...SURFACE HIGH PRESSURE WILL BE SLIDING OFF TO THE EAST WITH SPLIT STREAM FLOW ALOFT YIELDING TWO DIFFERENT STORMS UPSTREAM. FIRST...A POTENT H5 LOW WITH AN ARCTIC AIR MASS BEHIND IT WILL DIG OUT OF THE NORTHERN PLAINS. MEANWHILE A SOUTHERN STREAM STORM WILL GAIN STRENGTH AND MOVE ACROSS THE GULF STATES AS ENERGY PHASES BETWEEN THE TWO SYSTEMS. THIS WILL ALLOW MOISTURE TO OVERSPREAD THE AREA BY MONDAY NIGHT...WHICH WILL INITIALLY STRUGGLE TO OVERCOME DRY AIR AT THE SURFACE AND VEERING WINDS TO SOUTHEASTERLY...CREATING A DOWNSLOPE COMPONENT. HAVE INCREASED POPS TO LIKELY...MAINLY LATE MONDAY NIGHT AND THROUGH THE AFTERNOON ON TUESDAY. PRECIPITATION TYPE IS STILL IN QUESTION AS MANY DETAILS IN THE TRACK AND INTENSITY OF THE SYSTEM REMAIN AND VARIOUS DEGREES OF PHASING BETWEEN THE NORTHERN AND SOUTHERN STREAMS COULD OCCUR. AS A RESULT...WILL KEEP MENTION OF A RAIN OR SNOW POSSIBILITY AND HAMMER OUT THE DETAILS WITH A LATER FORECAST. THE WAY THINGS SHAPE UP NOW...IT APPEARS PRECIPITATION COULD BEGIN AS SNOW ON MONDAY NIGHT...THEN CHANGE OVER TO MOSTLY RAIN THROUGHOUT THE DAY ON TUESDAY...THEN BACK TO SNOW TUESDAY NIGHT AS A POWERFUL COLD FRONT SWEEPS THROUGH AND COLD AIR ADVECTION COMMENCES ON THE BACK END. FAVORED A BLEND OF THE GFS/ECMWF FOR THIS FORECAST PACKAGE WHICH WILL WRAP A DRY SLOT INTO THE AREA BY TUESDAY NIGHT. THEREAFTER...CLOSED UPPER LOW AXIS SHOULD SWING JUST NORTH OF THE AREA...CREATING STEEP LAPSE RATES ALONG WITH LINGERING LOW TO MID LEVEL MOISTURE. COULD GET SOME UPSLOPE ENHANCEMENT FROM LOW LEVEL SURFACE FLOW...HOWEVER THIS LOOKS TO BE MAINLY CONVECTIVELY DRIVEN FROM STEEP LOW AND MID LEVEL LAPSE RATES. SNOW SHOWERS SHOULD CONTINUE THROUGH WEDNESDAY NIGHT IN THE EAST BEFORE TAPERING OFF. THEREAFTER THE MAIN FORECAST CHALLENGE BECOMES HOW COLD IT GETS AS ARCTIC HIGH PRESSURE BUILDS IN FROM THE NORTHWEST. HAVE LEANED CLOSEST TO GFS/ECMWF RAW NUMBERS FOR THIS PORTION OF THE FORECAST AS THE MERCURY SHOULD STAY WELL BELOW CLIMO FOR THIS TIME PERIOD. && .AVIATION.../00Z TO 24Z/...UPDATED THE UPPER LOW PRESSURE SYSTEM IS OVER CENTRAL KENTUCKY WITH A TROUGH EXTENDING INTO EASTERN KENTUCKY. THE STEADY RAIN IS MOVING OUT OF EASTERN KENTUCKY AND THE RAIN WILL BECOME MORE INTERMITTENT WITH LINES OF SHOWERS MOVING ACROSS THE AREA WITH SOME DRIZZLE IN BETWEEN. THIS WILL RESULT IN THE CIGS BOUNCING UP AND DOWN A BIT WITH MOSTLY LIFR...WITH SOME PERIODS OF MVFR POSSIBLE AS WELL. WHEN THE LOW CONTINUES TO THE EAST...THEN SOME COLD AIR WILL ROTATE THROUGH THE AREA AND THE RAIN WILL TURN TO SNOW. AS IT DOES IT WILL BECOME PREDOMINANTLY LIFR WITH SOME TEMPO LIFR MIXED IN WITH THE HEAVIER SNOW SHOWERS. THIS SHOULD CONTINUE UNTIL ABOUT 22Z WHEN THINGS SHOULD BOUNCE BACK TO IFR AS THE LOW CONTINUES MOVING TO THE EAST AND THE MOISTURE AND LIFT BEGIN TO DECREASE. AS THE CONDITIONS TURN TO ALL SNOW...SNOW COVERED RUNWAYS COULD BECOME AN ISSUE. && .JKL WATCHES/WARNINGS/ADVISORIES... WINTER STORM WARNING UNTIL 4 PM EST SATURDAY FOR KYZ044-051-052- 104.
