NWS Jackson, KY wrote its last area forecast discussion before the first event at Mar 30, 7:22 AM EST, 2 hours 8 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 722 AM EST SUN MAR 30 2003 RECEIVED A COOP REPORT OF 2 INCHES OF SNOW AT WHITESBURG AT 1250 FEET IN LETCHER COUNTY. WILL UPDATE ZFP TO REMOVE ELEVATION REFERENCE FOR ADVISORY. WILL ALSO RAISE AMOUNTS TO ALLOW UP TO 4 INCHES ABOVE 2000 FEET. .JKL...WINTER WEATHER ADVISORY FOR SNOW FOR PIKE...LETCHER...AND HARLAN COUNTIES UNTIL 10 AM. HAL --------------------------------------------------------------------- PREVIOUS DISCUSSIONS FOLLOW --------------------------------------------------------------------- 620 AM EST SUN MAR 30 2003 WINTER WEATHER ADVISORY STILL IN EFFECT FOR FAR EASTERN COUNTIES...ABOVE 2000 FEET THROUGH 10 AM. REPORTS HAVE BEEN SPARSE. USING KY ROADWAY INFORMATION...ROADS SURFACES STILL ABOVE FREEZING IN MOST PLACES. REPORTS THAT WE HAVE BEEN ABLE TO TRACK DOWN INDICATE A HEAVY WET SNOW...LITTLE OR NO ACCUMULATIONS EXCEPT ON GRASSY AREAS...AND MAINLY AT THE HIGHER ELEVATIONS. TEMPERATURES HAVE BEEN DROPPING SLIGHTLY TO STEADY ACROSS MOST OF THE REGION. MAV NUMBERS WERE RUNNING A LITTLE LOW SO TOOK HIGH TEMPERATURES UP A BIT TODAY. WARM FRONT PUSHES THROUGH MONDAY NIGHT INTO TUESDAY MORNING. QUITE A BIT OF WARM AIR OVERRIDING THE FRONT. MODELS SHOW BEST POPS ARE FOR AREAS NORTH AND EAST OF HERE. TRIED TO REFLECT THAT IN MY ZONES. OTHERWISE...WEATHER STAYS DRY AND TEMPERATURES WARM BACK UP FOR THE REST OF THE WEEK. .JKL...WINTER WEATHER ADVISORY FOR SNOW ABOVE 2000 FEET FOR PIKE...LETCHER...AND HARLAN COUNTIES UNTIL 10:00 AM. RAY --------------------------------------------------------------------- 1050 PM EST SAT MAR 29 2003 ISSUED A WINTER WEATHER ADVISORY FOR SNOW ABOVE 2000 FEET IN OUR FAR EASTERN COUNTIES. A COUPLE OF SLUGS OF MOISTURE WILL SPREAD OVER EAST KENTUCKY TONIGHT AS A STRONG VORT AND TROUGH MOVE THROUGH AND LOW PRESSURE DEEPENS TO OUR EAST. THIS MOISTURE WILL BE ACCOMPANIED BY FALLING TEMPERATURES ON NORTHWEST...CAA...WINDS. THE SHOWERS WILL CHANGE TO SNOW SHOWERS AT THE HIGHER ELEVATIONS FIRST AND THEN MIX IN THE VALLEYS LATE. A ROADWAY OBSERVATION ON PINE MOUNTAIN INDICATES THAT SNOW IS FALLING OR WILL BE SOON BUT ROAD SFC TEMPERATURES ARE STILL IN THE LOWER 40S. THE EASTERNMOST COUNTIES ARE IN STORE FOR A COUPLE OF TENTHS OF LIQUID OVERNIGHT WITH MUCH LESS FURTHER WEST. A COUPLE OF INCHES OF SNOW IS POSSIBLE BY SUNDAY MORNING...BUT GIVEN THE WARM GROUND TEMPS...SHOULD ACCUMULATE MAINLY ON GRASSY SURFACES ON THE RIDGES. THE REST OF THE FORECAST IS IN PRETTY GOOD SHAPE WILL JUST FINE TUNE THE PRECIPITATION TYPE AND CHANCES OVERNIGHT...ADDING SNOW AMOUNTS WHERE APPROPRIATE. UPDATE TO ZONES AND RDF ALREADY OUT WITH GRIDS AND GRAPHICS TO FOLLOW SHORTLY. .JKL...WINTER WEATHER ADVISORY FOR SNOW ABOVE 2000 FEET UNTIL 10 AM EST FOR PIKE...LETCHER AND HARLAN COUNTIES. GREIF --------------------------------------------------------------------- 340 PM EST SAT MAR 29 2003 CURRENT SFC MAP FEATURES SFC COLD FRONT SOUTHEAST OF THE AREA...WITH LOWER 40S BEHIND CLOUD ENCOMPASSED AREAS BEHIND THE FRONT AND A FEW MIDDLE AND UPPER 40S TOWARDS WESTERN KY...WHERE SOME BREAKS IN THE CLOUD COVER OCCURRED. SOME LINGERING SHOWER/SPRINKLE ACTIVITY LAGGING BEHIND AS WELL. BIG WEATHER STORY DEALS WITH SNOW CHANCES FOR TONIGHT AS MID LVL WAVE ENHANCES SFC LOW DEVELOPMENT ALONG THE FRONT SOUTHWEST OF THE AREA. DECENT MODEL AGREEMENT CONCERNING THIS FEATURE...HOWEVER ETA CONTINUES TO BRING MORE QPF WITH THIS SYSTEM. THE HEAVIEST QPF LOOKS TO AFFECT OUR SOUTHEAST COUNTIES. GOOD DYNAMICS AND MODERATE LIFT IN THE MID LEVELS SHOULD HAVE NO PROBLEM GENERATING MEASURABLE PRECIP IN THESE AREAS. COLD AIR PROGGED TO CONTINUE ADVECTING IN FROM THE NORTHWEST. THIS SHOULD BE IN PLACE BY THE TIME THE QUICK BOUT OF PRECIP MOVES IN. GROUND TEMPERATURES WILL BE SLOW TO FALL IN VALLEYS TONIGHT...HOWEVER HIGHER ELEVATIONS WILL BE MORE SUSCEPTIBLE TO ACCUMULATING SNOW TOWARDS DAWN. I AM STILL GOING TO GO WITH AROUND AN INCH OF THE RIDGES. SOME RAIN MAY MIX IN WITH THE INITIAL ONSET...HOWEVER A CHANGE OVER TO SNOW SHOULD OCCUR BEFORE SUNRISE. CONTEMPLATED ISSUING AN ADVISORY FOR SNOW FOR ELEVATIONS ABOVE 2000 FEET...BUT WOULD RATHER LET THE EVENING SHIFT DECIDE TO PULL THE CORD...AS PRECIP WILL NOT MAKE AN IMPACT UNTIL EARLY TOMORROW MORNING. AFTER THE DISPOSAL OF THIS SYSTEM...ANOTHER QUICK MOVING VORT TRIES TO SWING THROUGH ON THE BACKSIDE OF THE EXITING H5 TROUGH...TRYING TO SQUEEZE OUT ANOTHER SMALL SHOT OF PRECIP FOR MONDAY. MODELS HAVE TRENDED SLIGHTLY WEAKER WITH THIS FEATURE AND WILL DOWNGRADE POPS TO SLIGHT CHANCE. KEPT TEMPS VERY SIMILAR TO PREVIOUS PACKAGE. EXTENDED...RISING HEIGHTS ARE EXPECTED THROUGH THE FIRST PART OF THE PERIOD...WITH RIDGING ALONG THE EAST COAST. SFC HIGH PRESSURE SHOULD REMAIN OVER THE SE US COAST AND BRING A WARMING SOUTHERLY FLOW STARTING AT MIDWEEK. 8H TEMPS IN BOTH THE ECMWF AND GFS ARE AROUND 9C OR SO FOR WED THROUGH THU. THIS WILL LEAD TO HIGHS IN THE LOW TO MID 70S. SOME RIDGE/VALLEY SPLITS IN LOW TEMPS ARE ALSO POSSIBLE ON WED AND THU AM. THE 0Z GFS IS MUCH QUICKER IN LIFTING A SW/V FROM THE WEST COAST AND INTO EASTERN CANADA AND WOULD PUSH AN ASSOCIATED COLD FRONT ACROSS THE REGION ON FRIDAY. THIS SOLUTION APPEARS TO BE AN OUTLIER AND IN HAVE FOLLOWED MORE OF AN ENSEMBLE GFS SOLUTION WHICH WOULD SHEAR OUT THE SW/V MOVING OUT OF THE WEST AS IT MOVES OVER THE EASTERN US RIDGE LATE FRI/SAT. AN ASSOCIATED COLD FRONT SHOULD APPROACH THE REGION BY SAT. HAVE INCLUDED CHANCE POPS FOR FRI AND SAT WITH THIS SYSTEM. HAVE GONE A BIT ABOVE MEX MOS FOR HIGH TEMPS THU AND FRI. GEOGERIAN/PELTON -------------------------------------------------------------------- 1245 PM EST SAT MAR 29 2003 UPDATED ZONES AS RAIN HAS ENDED OVER MOST ZONES AND TO GET RID OF MORNING WORDING. ALSO...TEMPS WERE RUNNING COOLER THAN PREVIOUS FORECAST AND GUIDANCE TEMPS. WORDED TEMPERATURES AS NEARLY STEADY 40 TO 45 NORTH AND MID 40S SOUTHEAST. SOME WEAK RETURNS WERE NOTED WEST OF THE SOUTHEASTERN MOST COUNTIES. WITH COLD ADVECTION CONTINUING...AND LAPSE RATES STEEPENING A FEW SPRINKLES CANNOT BE RULED OUT OVER THE SOUTHEASTERN HALF OF THE CWA...WITH CLOUDY SKIES AREA WIDE THIS AFTERNOON. NEXT QUESTION IS HOW TO HANDLE LIGHT MIXED PRECIP LATER TONIGHT. THE VA BORDER COUNTIES WILL HAVE THE BEST CHANCE OF SEEING ANY LIGHT SNOW ACCUMULATIONS ESPECIALLY HIGHEST ELEVATIONS. PELTON

SNOW WILL AFFECT MANY AREAS NEAR THE VIRGINIA BORDER THIS MORNING. ACCUMULATIONS WILL BE ELEVATION DEPENDENT...WITH AREAS ABOVE 2000 FEET RECEIVING AS MUCH AS 4 INCHES. HOWEVER...VALLEY LOCATIONS BELOW 1500 FEET WILL BE NEAR OR ABOVE FREEZING DURING THE SNOW...AND MAY ALSO HAVE RAIN MIXED IN. THIS SHOULD KEEP ACCUMULATIONS TO AROUND 2 INCHES OR LESS IN THE VALLEYS. THE STEADY PRECIPITATION WILL TAPER OFF BY LATE THIS MORNING. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY. NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME. .SPOTTER INFORMATION STATEMENT...
