AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
1108 AM CDT TUE APR 10 2012

.UPDATE...ADDED AVIATION SECTION FOR 18Z TAF'S.

&&

.AVIATION...BNA/CKV/CSV...HIGH PRESSURE CONTINUES TO BUILD INTO
MIDDLE TENNESSEE, WITH MID-LEVEL MOISTURE PRODUCING SOME
CLOUDINESS ACROSS THE MID STATE TODAY. EXPECT GUSTY WINDS THIS
AFTERNOON AS THE PRESSURE GRADIENT CONTINUES TO TIGHTEN UP, WITH
DRY LOW LEVELS AND VFR WX THE NEXT 24 HRS.

&&

.PREV DISCUSSION... /ISSUED 641 AM CDT TUE APR 10 2012/

UPDATE...FOR AVIATION.

AVIATION...
12Z TAFS...VFR THROUGH THE PERIOD. A COLD FRONT AND SHORTWAVE WILL
CROSS THE REGION THIS MORNING WITH SCT-BKN MID LEVEL CLOUDS. GUSTY
NW WINDS WILL FOLLOW FROPA...TO 20KT AT TIMES. WINDS WILL DIMINISH
TONIGHT UNDER SKC.

13

PREV DISCUSSION... /ISSUED 343 AM CDT TUE APR 10 2012/

DISCUSSION...
FORECAST REASONING WILL LEAN TOWARD A CONSENSUS MODEL SOLUTION
COMPROMISE FOR THE FORECAST PERIOD UNLESS OTHERWISE NOTED.

MAIN FORECAST QUANDARIES...FROST/FREEZE POTENTIAL TONIGHT AND
WED NIGHT...TEMPS...OVERALL WX PATTERN THIS WEEKEND INTO EARLY
NEXT WEEK.

AS FOR TODAY...AS OF 08Z...NOTING THE WEAK DISTURBANCE ALOFT ACROSS
MO MOVING CLOSER TO THE MID STATE IN NWLY UPPER LEVEL FLOW. WEAK
SFC BOUNDARY ACROSS SWRN PORTIONS OF THE MID STATE ALSO. BELIEVE
OVERALL THAT THE NAM HANDLES THIS BEST WITH MOVING THIS DISTURBANCE
THRU THE MID STATE THIS MORNING...WITH DECREASING CLOUDINESS THIS
AFTERNOON. DO NOT HAVE A LOT OF CONFIDENCE IN THE GFS SOLUTION PER
ITS DEVELOPMENT OF ISO/SCT SHWRS WITH THIS FEATURE. THE SFC
BOUNDARY IS EXPECTED TO MOVE SWD DURING THE DAY...MOVING WELL S OF
THE MID STATE BY THE AFTERNOON HRS...NOT PROVIDING AN ADDITIONAL
FOCUSING MECHANISM FOR SHWR DEVELOPMENT WITH DIURNAL HEATING
INFLUENCES PLAYING A ROLE ALSO. CAN NOT TOTALLY RULE OUT THE
FORMATION OF SOME SHWRS ACROSS SW PORTIONS OF THE MID STATE...
PER THE LATEST RUN OF THE HIGH RESOLUTION RAPID REFRESH DEPICTING
SOME POTENTIAL FOR ISO SHWRS PASSING ACROSS THE SW CORNER OF THE
MID STATE LATER THIS MORNING/EARLY AFTERNOON. BUT OVERALL...JUST DO
NOT FEEL CONFIDENT ENOUGH AT THIS TIME TO MENTION ANY CHANCES OF
RAINFALL. THUS...WILL LEAVE THE MID STATE DRY TODAY. WITH CLOUD
COVERAGE AND SOME COOLER AIR WORKING IN ACROSS THE MID STATE
.WILL GO WITH HIGHS AROUND 70 N TO LOWER 70S S...UPPER 60S PLATEAU.

AS FOR TONIGHT...ONE OF THE MAIN FORECAST QUANDARIES CENTERS AROUND
POTENTIAL FROST/FREEZE CONDITIONS THAT COULD BE EXPERIENCED TONIGHT.
STRONG CANADIAN HIGH PRESSURE WILL BE BUILDING INTO THE MID STATE
BY LATE TONIGHT...ALONG WITH CLRING SKIES...AS DRY NWLY FLOW REESTABLISH
ITSELF ACROSS THE MID STATE...AS THE UPPER LEVEL RIDING PATTERN BECOMES
MORE ENHANCED ACROSS THE ROCKIES WITH AN UPPER LEVEL LOW CENTERED
ACROSS THE ERN GREAT LAKES REGION WITH TROUGHING DOWN THE ATLANTIC
COASTLINE. THERE IS SOME CONCERNS THAT WINDS WILL BE LIGHT ENOUGH THAT
IT WILL ALLOW FOR SOME MIXING NEAR THE GROUND AND THUS NOT ALLOW FOR
MAXIMUM RADIATIONAL COOLING POTENTIAL TO BE THE KEY PLAYER IN COOLING
THE AIR NEAR THE GROUND THAT WOULD BE NEEDED FOR PATCHY TO AREAS
OF FROST DEVELOPMENT ACROSS THE ENTIRE MID STATE. HOWEVER...FOR
LOCATIONS W OF THE PLATEAU...BELIEVE THAT SOME OF THE LOWER LYING
LOCATIONS WILL BE SUSCEPTIBLE TO PATCHY FROST DEVELOPMENT AS ANY
WINDS IN THESE LOCATIONS WILL SHOULD BE CLOSE TO CALM. SO NEAR
PRESS TIME...WILL ALSO ISSUE A FROST ADVISORY FOR THE LOWER LYING
LOCATIONS W OF THE PLATEUA FOR LATE TONIGHT. ACROSS THE PLATEAU...TEMPS
SHOULD GET CLOSE TO FREEZING...BUT AT THIS TIME...DO NOT HAVE THE
OVERALL CONFIDENCE TO BELIEVE THAT THIS WILL BE FOR CERTAIN...I.E.
THE ISSUANCE OF A FREEZE WARNING FOR THE PLATEAU...ESPECIALLY FOR
THE NRN PORTIONS OF THE PLATEAU...AND WILL THUS LET THE WATCH STAND
FOR NOW AND DEFER TO LATER MODEL RUNS...ANALYSIS...AND FORECASTERS
REASONING.

AS FOR WED...EXPECT CANADIAN HIGH PRESSURE INFLUENCES TO CONTINUE
BUILDING ACROSS THE MID STATE ON WED...WITH LITTLE IN THE WAY OF
CLOUDINESS...AND EVEN COOLER TEMPS...NOW 5 TO 10 DEGREES BELOW
SEASONABLE NORMS FOR THIS TIME OF YEAR. HIGHS WILL BE AROUND 60 N
TO MID 60S S...MID 50S PLATEAU.

AS FOR WED NIGHT...WITH ANOTHER CLR NIGHT IN STORE...AND APEX OF
CANADIAN HIGH PRESSURE CENTER WORKING ITS WAY TOWARD THE MID
STATE...OVERALL...BELIEVE THAT THE POTENTIAL FOR AREAS OF FROST
WILL BE THE GREATEST ACROSS THE ENTIRE MID STATE...AND EVEN A
STRONGER POSSIBILITY OF FREEZING TEMPS ACROSS THE PLATEAU. WILL
MENTION THIS POSSIBILITY IN THE MORNING HWO ISSUANCE. LOWS WILL
BE IN THE MID 30S...AROUND 30 PLATEAU.

AS FOR THU...AS SFC HIGH MOVES TO OUR E...THIS SHOULD ALLOW SOME
WARMER TEMPS ON THU...AS RIDGING ALOFT BECOMES MORE AND MORE
ENHANCED. WILL GO WITH HIGHS IN THE MID 60S...LOWER 60S PLATEAU.

AS FOR THE REMAINDER OF THE FORECAST PERIOD...FOR THE UPCOMING WEEKEND
AND INTO EARLY NEXT WEEK...UPPER LEVEL RIDGING WILL BE THE MAIN WEATHER
PLAYER ACROSS THE SE U.S WITH SOME QUESTION AS WHETHER THE MID STATE
WILL BE FAR ENOUGH AWAY FROM THE APEX OF THE UPPER LEVEL RIDGING
INFLUENCES TO EXPERIENCE THE POTENTIAL OF SHWRS/TSTMS AROUND ITS
PERIPHERY. BELIEVE WRN LOCATIONS NEAR THE TN RIVER VALLEY WILL HAVE
A SLIGHT CHANCE OF SHWRS/TSTMS ON SAT...AND AS UPPER LEVEL RIDGING
INFLUENCES SLOWLY MOVE EWD...MORE OF THE AREA WILL ON SUN...INCLUDING
MUCH OF THE NASHVILLE METRO AREA...WILL HAVE THE POSSIBILITY OF
EXPERIENCING SOME SHWRS/TSTMS. THIS SLIGHT CHANCE SHOULD SPREAD TO
THE ENTIRE MID STATE ON MON WITH A CHANCE OF SHWRS/TSTMS BY MID
WEEK AS THESE UPPER LEVEL RIDGING DYNAMICS CONTINUE TO MOVE EWD
AND WEAKEN...ALONG WITH A SFC FRONTAL SYSTEM APPROACHING THE MID
STATE. A QUICK RETURN TO WARMER THAN NORMAL AFTERNOON HIGH TEMPS
FOR THIS TIME OF YEAR WILL RETURN TO THE MID STATE TOO...WITH HIGHS
MAINLY IN THE MID TO UPPER 70S. LOWS WILL ALSO WARM FROM THE LOWER
40S...UPPER 30S PLATEAU ON THU NIGHT INTO THE MID 50S ACROSS MOST
OF THE MID STATE BY MON NIGHT.
