Area forecast discussion, Apr 12, 1:24 PM EDT, 52 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
124 PM EDT TUE APR 12 2016
.SYNOPSIS...
COLD FRONT EXITS THIS MORNING...DRIER AIR SINKS SOUTH IN ITS WAKE.
HIGH PRESSURE CENTERED TO OUR NORTH AND NORTHEAST...PROVIDES
PROLONGED PERIOD OF EAST TO SOUTHEAST FLOW.
&&
.NEAR TERM /THROUGH TONIGHT/...
930 AM UPDATE...SKIES CONTINUE TO CLEAR FROM WEST TO EAST THIS
MORNING BEHIND THE FRONT WITH RIDGING BUILDING IN. HAVE UPDATED
SKY FORECAST TO REFLECT VISIBLE IMAGERY AND CURRENT OBS/TRENDS
ACROSS THE REGION. NO FURTHER UPDATES ARE NEEDED AT THIS TIME.
PREVIOUS DISCUSSION...
AS OF 600AM THE COLD FRONT HAD PUSHED THROUGH BKW AND EKN. RELIED
FAIRLY HEAVILY ON THE HRRR FOR MARCHING THE COLD FRONT AND POPS
ACROSS THE REMAINDER OF THE CWA EARLY THIS MORNING. THE COLD FRONT
SHOULD BE EXITING TO THE EAST JUST AFTER SUNRISE...HOWEVER
FORECAST SOUNDINGS SHOW LOW LEVEL MOISTURE LINGERING ACROSS THE
MOUNTAINS. CODED UP SOME DRIZZLE EARLY THIS MORNING ACROSS THE
EASTERN HALF OF THE CWA AS THIS MOISTURE GETS SQUEEZED OUT.
HIGH PRESSURE MOVES INTO THE GREAT LAKES REGION TODAY...AND CLOUDS
WILL GRADUALLY BREAK UP FROM WEST TO EAST. EXPECT A GOOD
RADIATIONAL COOLING NIGHT TONIGHT WITH LITTLE TO NO CLOUD COVER.
LOWS TONIGHT ARE A BIT TRICKY AS GUIDANCE IS HOVERING ON EITHER SIDE
OF FREEZING FOR ALL BUT HIGHEST ELEVATIONS WHICH ARE COLDER. USED
LOCALLY PRODUCED MOS BASED ON COOP SITES FOR LOWS TONIGHT. THIS
PRODUCT DOES FAIRLY WELL CAPTURING THE COLD SPOTS IN SE OHIO AND NE
KENTUCKY. FOR EXAMPLE THIS GUIDANCE GIVING AROUND 30 IN THE LOWER
SPOTS OF GREENUP AND CARTER COUNTY KY. WITH THIS IN MIND...CONVERTED
THE FREEZE WATCH TO A WARNING...AND ADDED NE KY AND LAWRENCE COUNTY
OHIO TO THE MIX. FOR THE COUNTIES ALONG THE OHIO AND TUG
FORK...FREEZING TEMPERATURES ARE ONLY EXPECTED AWAY FROM THE RIVERS
IN OUTLYING AREAS.
&&
.SHORT TERM /WEDNESDAY THROUGH FRIDAY/...
THE HIGH PRESSURE CENTER NEVER SETTLES IN OUR VICINITY BUT RIDGES
DOWN THE PIEDMONT FROM ITS CENTER TO OUR NORTHEAST. AS A RESULT...
LOW LEVEL FLOW TURNS WEAK EAST AND SOUTHEAST WEDNESDAY NIGHT THROUGH
FRIDAY. ENOUGH LOW LEVEL FLOW OVER MOUNTAINS...AND SOUTHERN PLATEAU
IN THE VICINITY OF BKW...TO KEEP TEMPERATURES A FEW DEGREES MILDER
AT NIGHT...AND A BIT LOWER DURING THE DAY.
THE SOUTHERN SYSTEM WEAK CUT OFF OVER THE LOWER MISSISSIPPI VALLEY ON
THURSDAY...MAY SPILL SOME HIGH CLOUDS NORTH. THE 00Z NAM WAS MOST
AGGRESSIVE WITH SOME DEEPER MOISTURE CREEPING NORTH BY THURSDAY
EVENING...INTO OUR SOUTHERN COUNTIES. WILL LEAVE POPS AOB 14 PERCENT
IN OUR SOUTHERN COUNTIES. MID/UPPER RIDGE AXIS OVER US WITH WEAK
WINDS AT THOSE LEVELS.
AFTER THE INITIAL 850 MB WARMING ON WEDNESDAY...TEMPERATURES ALOFT
SLOW TO WARM. SO NO BIG JUMP IN HIGH TEMPERATURES FOR THURSDAY AND
FRIDAY. AS MENTIONED...TRIED TO HOLD DOWN THE EASTERN SLOPES A BIT
ON MAXIMUM TEMPERATURE DUE TO THE WEAK EAST AND SOUTHEAST LOW LEVEL
FLOW.
&&
.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
VAST MAJORITY OF MODELS IN GOOD AGREEMENT. THIS PERIOD LOOKS QUIET
WITH A STRENGTHENING UPPER RIDGE OVER THE GREAT LAKES AND OHIO
VALLEY FRIDAY...QUICKLY DEVELOPING INTO A STATIONARY UPPER HIGH BY
THE WEEKEND. THIS UPPER HIGH OVER OUR AREA WILL HELP FORM A WELL
DEFINED OMEGA BLOCK OVER THE CONTINENTAL U.S...WITH ONE UPPER LOW
OVER THE SOUTHWEST U.S. AND ANOTHER OFF THE SOUTHEAST U.S. COAST.
THIS PATTERN PROTECTS US FROM SOUTHERN STREAM SYSTEMS TRYING TO
EJECT OUT OF THE SOUTHWESTERN U.S. UPPER LOW. AS THE HIGH DEVELOPS
AT THE SURFACE AND ALOFT...LOOK FOR A WARMING TREND WITH QUITE DRY
WEATHER AND ABUNDANT SUNSHINE. FOR THE LOW LANDS...TEMPERATURES WILL
WARM FROM THE 60S FRIDAY TO WELL INTO THE 70S BY MONDAY...WITH NIGHT
TIME LOWS MOSTLY STAYING ABOVE FREEZING.
&&
.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
15Z UPDATE...AS OF 15Z SKIES HAVE CLEARED IN EVERY LOCATION
EXCEPT FOR EKN AND BKW. BASED ON THE CURRENT WEST TO EAST
PROGRESSION OF STRATUS FIELD...IT SHOULD NOT BE MUCH MORE THAN AN
HOUR FOR THOSE SITES TO RISE TO VFR AS WELL AND ALL SITES LOOK TO
REMAIN VFR WITH HIGH PRESSURE MOVING OVERHEAD.
PREVIOUS DISCUSSION...
HIGH PRESSURE IS MOVING OVER THE AREA WITH MOSTLY CLEAR SKIES AND
VFR CONDITIONS EXPECTED THROUGH THE TAF PERIOD.
GENERALLY LIGHT NORTHERLY WINDS EXPECTED THROUGH THE TAF PERIOD.
