AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON KY
148 PM EDT SUN MAY 22 2011

.SHORT TERM.../THE REST OF TODAY/

EASTERN KENTUCKY REMAINS IN THE WARM SECTOR OUT AHEAD OF A LOW
PRESSURE SYSTEM CURRENTLY SWIRLING ACROSS THE NORTHERN PLAINS.
DEWPOINTS ARE RUNNING A FEW TO SEVERAL DEGREES WARMER THAN YESTERDAY
AT THIS TIME. CURRENT MOSAIC RADAR SHOWS A CLUSTER OF SHOWERS AND
THUNDERSTORMS MOVING THROUGH INDIANA...ASSOCIATED WITH A TRAVERSING
SHORT WAVE TROUGH. THE TAIL END OF THIS FEATURE MAY BE ABLE TO KICK
OFF SOME ISOLATED ACTIVITY AS IT APPROACHES EARLY THIS
AFTERNOON...HOWEVER THE MORE INTERESTING FEATURE IS THE ONGOING MCS
IN AR/TN. THE 12Z WRF/HRRR GENERALLY SUSTAIN THIS COMPLEX AS IT
MOVES THROUGH TENNESSEE AND SOUTH CENTRAL KENTUCKY AND EVENTUALLY
PORTIONS OF EASTERN KENTUCKY. THE 12Z WRF DOES LOOK A BIT FAST
COMPARED TO THE RADAR TRENDS...WITH THE HRRR HAVING THE BETTER HANDLE
OF THE TIMING. BETWEEN 19 AND 20Z...THE EDGE OF THE FORCING FROM THIS
COMPLEX WOULD BE ON DOORSTEP. AS SUCH...WILL INCREASE POPS INTO THE
GOOD CHANCE RANGE FOR ALONG AND WEST OF I-75...AND MAINTAIN 40
PERCENT ELSEWHERE. A FEW STORMS MAY APPROACH SEVERE LIMITS TODAY WITH
MODERATE INSTABILITY AND SHEAR AVAILABLE. HIGH TEMPERATURES PEAKING
IN THE MIDDLE 80S LOOK ON TARGET.

THE PREVIOUS SHORT TERM FORECAST DISCUSSION FOLLOWS...

/EARLY MORNING/

AS SUSPECTED...A FEW OBS STATIONS AROUND THE CUMBERLAND WHERE THE
HEAVIER RAINS FELL ON SATURDAY ARE REPORTING VISIBILITIES HAVE
DROPPED TO LESS THAN A MILE WHERE SKIES HAVE CLEARED OUT. SAT IMAGERY
SHOWS THE SWATH OF MID LEVEL CLOUDS CONTINUING TO SHIFT EAST AND
EXPECT THAT FOG WILL CONTINUE TO DEVELOP IN AND AROUND THE RIVER
VALLEYS...PARTICULARLY IN AREAS THAT SAW RAIN ON SATURDAY AND HAVE
ISSUED AN SPS TO COVER THIS. ONCE THE SUN COMES UP...THE FOG SHOULD
BEGIN TO LIFT AS HEATING COMMENCES...AND IS EXPECTED TO MIX OUT
ENOUGH BY 9 AM THAT IT WILL NO LONGER IMPACT MORNING MOTORISTS.

THE PREVIOUS SHORT TERM FORECAST DISCUSSION FOLLOWS...

/TODAY THROUGH TUESDAY/

ACTIVITY FROM SATURDAY EVENING HAS DWINDLED AND MOVED INTO OH AS OF
06Z LEAVING A STRATOCU CU DECK OVER EAST KENTUCKY THIS MORNING. JUST TO
THE WEST...SKIES HAVE CLEARED OVER THE HEART OF THE COMMONWEALTH
ALLOWING FOR AREAS OF DENSE FOG TO DEVELOP. NOT SEEING ANY PROBLEMS
YET OUTSIDE OF THE USUAL FOG PRONE AREAS BUT WITH THE CLEARING SKIES
EXPECTED TO BEGIN MOVING IN OVER THE AREA BEFORE SUNRISE WILL
CONTINUE TO MONITOR CONDITIONS CLOSELY...ESPECIALLY AROUND THE
CUMBERLAND WHERE MOST OF THE HEAVIER RAINS FELL YESTERDAY AS AN
ADVISORY OVER PORTIONS OF THE AREA MAY BECOME NECESSARY.

06Z SFC ANALYSIS SHOWS THE DEEP LOW PRESSURE SYSTEM OVER THE
NRN/CENTRAL PLAINS WITH AN OCCLUDED FRONT STRETCHING EAST ACROSS SRN
MN/WI AND BECOMING MORE DIFFUSE THRU CENTRAL IN/SRN OH. LATEST IR/WV
IMAGERY SHOWS THE STACKED UPPER LOW CHURNING OVER THE NRN HIGH PLAINS
DRIFTING EAST...WITH A COUPLE OF NOTABLE SHORT WAVES ROTATING AROUND
THE LOW. ONE OF THESE WAVES CURRENTLY OVER NRN AR/SRN MO MAY BECOME
A FOCUS FOR CONVECTION CLOSER TO HOME THIS AFTERNOON AS THE LLJ
CURRENTLY NOSING UP THE MS VALLEY SHIFTS EAST TODAY...SENDING AMPLE
GULF MOISTURE INTO THE TN AND OH VALLEYS. FCST SOUNDINGS CONTINUE TO
ADVERTISE PLENTY OF INSTABILITY DEVELOPING AROUND THE AREA THIS
AFTERNOON AND LINGERING OVERNIGHT. ANY TSTMS THAT DEVELOP WILL HAVE
THE POTENTIAL TO REACH SEVERE LIMITS...PARTICULARLY OVER OUR WRN
COUNTIES WHERE THE BETTER MOISTURE RETURN LOOKS TO SET UP...WITH
STRONG WIND GUSTS AND HAIL THE PRIMARY THREATS. EXPECT THAT ANY
ACTIVITY THIS EVENING WILL BE STRONG ENOUGH TO SUSTAIN ITSELF THRU
THE EARLY OVERNIGHT HOURS...SO HAVE RAISED POPS INTO THE GOOD CHANCE
RANGE FOR BOTH PERIODS.

FOR MONDAY...THE CONSENSUS AMONG THE MODELS CONTINUES TO SUGGEST
ANOTHER POTENT SHORT WAVE RIDING UP THRU THE SW FLOW OVER THE TN/OH
VALLEYS AT SOME POINT DURING THE DAY. HOWEVER...DIFFERENCES IN THE
EXACT TIMING...STRENGTH...AND PLACEMENT OF THE WAVE STILL HAVE TO BE
SORTED OUT BUT AGAIN...WITH AMPLE INSTABILITY REDEVELOPING DURING THE
MORNING AND A 30 TO 40 KT LLJ OVERHEAD ANY SPARK WILL LIKELY BE
ENOUGH TO TRIGGER STRONG THUNDERSTORMS OVER THE AREA...WITH DAMAGING
WINDS AND HAIL AGAIN THE MAIN THREATS...AND HAVE MAINTAINED GOOD
CHANCE POPS THRU BOTH PERIODS.

BY TUESDAY A SLOW MOVING COLD FRONT IS EXPECTED TO STALL OVER THE
OHIO VALLEY AS A LOW PRESSURE SYSTEM WINDS UP OVER THE SRN/CENTRAL
PLAINS. SW SFC FLOW IS EXPECTED TO CONTINUE TO PROVIDE SOME MOISTURE
THRU THE LOWEST LEVELS HOWEVER DEEP MOISTURE LOOKS TO BE LACKING AS
THE LLJ VEERS AND EAST KY BECOMES CUTOFF FROM THE BETTER GULF
MOISTURE. STILL...WITH A FRONTAL BOUNDARY NEARBY AND MODELS
INDICATING CONSIDERABLE INSTABILITY REDEVELOPING DURING THE DAY YET
AGAIN...HAVE KEPT THE CHANCES FOR THUNDER GOING THRU THE DAY...WITH
THE BETTER CHANCES ALONG THE OH RIVER CLOSER TO THE FRONT.

FOR TEMPERATURES...USED A BLEND OF THE LATEST MAV/MET NUMBERS WITH
THE INHERITED FORECAST...WHICH DID NOT CHANGE ALL THAT MUCH. WILL
CONTINUE TO FAVOR THE MORE LIMITED DIURNAL RANGE THRU THE PERIOD THAN
WHAT THE GUIDANCE HAS SUGGESTED...WITH HIGHS INTO THE MID 80S TODAY
AND TOMORROW...AND OVERNIGHT LOWS IN THE LOWER TO MID 60S.

.LONG TERM.../TUESDAY NIGHT THROUGH SATURDAY/

PERIODIC CHANCES FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH
THE REMAINDER OF THE WORK WEEK AS A SERIES OF MID LEVEL DISTURBANCES
ACROSS THE OHIO AND TENNESSEE VALLEYS. AT THIS POINT...OPTING TO
KEEP POPS LOWER DO TO UNCERTAINTY IN PLACEMENT AND STRENGTH OF ANY
OF THESE WAVES. MEX GUIDANCE POPS ARE QUITE HIGH THROUGH THE WEEK
AND I CANNOT DISPUTE THESE HIGH POPS. GIVEN THE PROGRESSIVE NATURE
OF THESE WAVES...WE COULD SEE A ROUND OF PRECIPITATION DURING EACH
12 HOUR PERIOD THIS WEEK. HOWEVER...THERE WILL ALSO BE PLENTY OF DRY
PERIODS. THUS...CHANCE POPS SEEM LIKE A COMPROMISE FOR NOW. THE MAIN
UPPER LEVEL TROUGH WILL EJECT INTO KENTUCKY BY THURSDAY. GIVEN THE
STRENGTH AND FORCING ASSOCIATED WITH THIS FEATURE...GOING TO GO
LIKELY DURING THIS PERIOD INTO THURSDAY NIGHT. THE TROUGH MAY STALL
OVER THE AREA BY WEEKS END WHICH COULD KEEP SOME LIGHT PRECIPITATION
AROUND INTO NEXT WEEKEND. GOING TO CONTINUE TO UNDERCUT GUIDANCE
WITH RESPECT TO HIGHS AND GO CLOSE TO GUIDANCE AT NIGHT.

&&

.AVIATION.../18Z TO 18Z/...UPDATED

A BROKEN LINE OF THUNDERSTORMS MOVING IN FROM CENTRAL TENNESSEE AND
WESTERN KENTUCKY WILL REACH SME BETWEEN 20 AND 21Z AND LOZ BETWEEN 21
AND 22Z. AM COUNTING ON THESE HOLDING TOGETHER ENOUGH FOR TEMPORARY
MVFR IMPACT AT BOTH TERMINALS AT THESE TIMES. AT JKL...THERE IS MORE
UNCERTAINTY...AND WILL ONLY CARRY A VCTS. DEPENDING UPON CLEARING AND
THE AMOUNT OF RAINFALL RECEIVED...IFR FOG AT BOTH SME AND LOZ IS
CERTAINLY POSSIBLE. FOR NOW...HAVE CONTINUED TO MENTION A DROP DOWN
TO MVFR. OVERNIGHT...A LOW LEVEL JET WILL RAMP UP ACROSS THE OHIO
VALLEY...BRINGING A RENEWED THREAT OF CONVECTION ACROSS THE AREA. THE
CONVECTION WILL LIKELY EASE UP BY THE MID-MORNING HOURS ON
MONDAY...WITH ONLY WIDELY SCATTERED STORMS POSSIBLE LATER IN THE
AFTERNOON. SOUTHWEST WINDS OF 5 TO 10 KTS WILL LIGHTEN UP TOWARDS
DUSK THIS EVENING...AND THEN RAMP UP TO AROUND 10 KTS AFTER 15Z ON
MONDAY.

.JKL WATCHES/WARNINGS/ADVISORIES...NONE.
