AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
330 PM EST TUE FEB 9 2016

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY NIGHT)
ISSUED AT 330 PM EST TUE FEB 9 2016

WATER VAPOR AND MESOANALYSIS STILL DEPICTING A DEEP AND BROAD
AREA OF CYCLONIC FLOW ACROSS MUCH OF THE EASTERN CONUS. THIS IS
LEADING TO SNOW SHOWERS AND MAYBE EVEN SNOW SQUALLS AT TIMES.
GIVEN THIS GENERAL FLOW AND THE OPEN GREAT LAKE WATERS SOME OF OUR
MOISTURE IS COMING OFF THE LAKES. MOST OF THE SNOW SHOWERS WILL
REMAIN LIGHT...BUT OF FEW OF THESE SHOWERS COULD BE MODERATE TO
EVEN HEAVY AT TIMES. THIS WILL STILL LEAD TO ADDITIONAL LIGHT
ACCUMULATIONS AND REDUCTIONS IN VISIBILITY. OVERALL GIVEN THIS
WILL OPT TO LEAVE OUR CURRENT ADVISORY AS IS.

THE OTHER STORY WILL BE THE CONTINUAL COLD AIR ADVECTION
OVERTIME...WE WILL SEE TEMPERATURES DROPPING INTO THE MID TEENS
OVERNIGHT. BASED ON THE SOUNDINGS WE COULD SEE OCCASIONAL GUSTS
AT TIMES WITH DECENT MIXING...SO DID KEEP SOME GUSTY WINDS AT
TIMES TONIGHT. NOW FOR WEDNESDAY THIS BROAD LOW WILL BEGIN TO EXIT
EAST AND THIS WILL AID IN WAINING THE SNOW SHOWERS THROUGH THE DAY
FROM SW TO NE. THE CLOUDS SHOULD ALSO BEGIN EXITING THE REGION IN
THE SAME FASHION...TEMPS WILL REMAIN WELL BELOW NORMAL WITH HIGHS
TOPPING OUT IN THE LOW 20S AND EVEN TEENS IN SOME OF THE HIGHER
TERRAIN. THE POTENTIAL FOR CLEARING SKIES COULD LEAD TO A VERY
COLD NIGHT THURSDAY NIGHT...HOWEVER THERE IS SOME UNCERTAINTY ON
CLEARING IN THE SW DUE TO ANOTHER WAVE. THERE REMAINS A FAIR
AMOUNT OF UNCERTAINTY ON THE TRACK AND IF WE GET ANY CHANCE OF
PRECIP IN THAT AREA...RIGHT NOW KEEPING IT DRY. EITHER WAY RIGHT
NOW TEMPS LOOK TO DROP INTO THE SINGLE DIGITS.

.LONG TERM...(THURSDAY THROUGH TUESDAY)

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY AFTERNOON)
ISSUED AT 1250 PM EST TUE FEB 9 2016

SCATTERED TO NUMEROUS SNOW SHOWERS ARE STILL THE STORY THIS
AFTERNOON AND WSR-88D IS INDICATING SOME OF THESE SHOWERS MAY BE
HEAVY AT TIMES. THE HEAVIER SNOW SHOWERS ARE VERY DIFFICULT TO
PIN DOWN AND FOR NOW USED A TEMPO GROUP TO HANDLE THIS. GENERALLY
MOST SITES WILL SEE MVFR TO IFR CONDITIONS FROM TIME TO TIME.
OTHERWISE WE SHOULD BEGIN TO SEE IMPROVING TAFS IN TERMS OF
VIS...AS SNOW SHOWERS AND FLURRIES BEGIN TO EXIT THE REGION WED
AFTERNOON AND NIGHT. WINDS WILL GENERALLY REMAIN LIGHT OUTSIDE OF
ANY HEAVIER SNOW SHOWER/SQUALL...WHERE WINDS COULD BRIEFLY GUST
15 TO 20 KTS.
