AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
847 PM EST THU FEB 24 2011

...MESOSCALE UPDATE...

MESOSCALE UPDATE 2...

LOW-LEVEL HELICITY CONTINUES HIGH. VWP FROM KHPX INDICATES 70 KNOT
WINDS AT 3 KFT. SURFACE INSTABILITY A LITTLE WEAK WITH TEMPERATURES
IN THE MID 50S...BUT UPSTREAM SITES OVER WESTERN KENTUCKY HAVE
REPORTED WIND DAMAGE...POTENTIALLY TORNADIC...AS WELL AS SOME HAIL.
BASED ON THIS POTENTIAL...HAVE ISSUED A TORNADO WATCH ACROSS SOUTH
CENTRAL KENTUCKY UNTIL 07Z.

MESOSCALE UPDATE 1...

SFC LOW PRESSURE SYSTEM OVER NE ARKANSAS AND ASSOCIATED UPPER LEVEL
TROUGH OVER KANSAS/OKLAHOMA AS OF 0Z THIS EVENING WILL CONTINUE ENE
PROGRESS TONIGHT BRINGING STRONG TO SEVERE STORMS TO SOUTH CENTRAL
KY.  LOOKING AT THE 21Z HRRR AND 18Z NAM...THE SFC LOW WILL
STRENGTHEN AS IT MOVES NE THROUGH NORTH CENTRAL KY ALONG A SFC
BOUNDARY AND AXIS OF PRESSURE FALLS.  LARGE SCALE ASCENT ASSOCIATED
WITH THIS SYSTEM AS WELL AS A 70 TO 80 KT H85 JET...30 KTS 0-1 KM
WIND SHEER...AND LOW LCL/S ALL SUPPORT STRONG CONVECTION WITH
DAMAGING WINDS AND ISOLATED TORNADOS BEING THE MAIN THREATS.
CONVECTIVE MODE LOOKS TO REMAIN SIMILAR TO WHAT WE/VE SEEN OUT TO
OUR WEST THIS EVENING...LOTS OF BOWING/LEWP SEGMENTS ALONG THE MAIN
LINE ASSOCIATED WITH THE COLD FRONT WITH ISOLATED STRONG CELLS JUST
AHEAD OF THE LINE.  ISOLATED TORNADOS/DAMAGING WINDS COULD POSE A
THREAT IN EITHER TYPE OF CONVECTION.  WOULDN/T BE SURPRISED TO SEE A
TOR WATCH SOMETIME THIS EVENING FOR SOUTH CENTRAL KY POSSIBLY INTO
THE BLUEGRASS REGION DEPENDING ON HOW FAR NE THAT SFC LOW TRACKS.
STAY TUNED TO WEATHER.GOV AND NOAA WEATHER RADIO FOR THE LATEST
WATCH/WARNING INFO.

IN ADDITION TO THE SEVERE THREAT...FLOODING WILL STILL BE A THREAT
TONIGHT AS THE HEAVY CONVECTION MOVES THROUGH THE AREA.  CENTRAL KY
IS MOST PRIMED FOR THIS THREAT AS THEY HAVE RECEIVED 1-2 INCHES OF
RAINFALL AS OF 7PM EST THIS EVENING.  FLOODING PROBLEMS MAY BE MINOR
ADVY LEVEL TYPE OR THEY COULD ESCALATE TO FLASH FLOODING IF WE GET A
PERIOD OF TRAINING STORMS.  WILL CONTINUE TO MONITOR.

FINALLY...WILL BE UPDATING THE WIND GRIDS TO SHOW SOME STRONGER
WINDS AHEAD OF THE MAIN LINE OF CONVECTION AS THE SFC PRESSURE
GRADIENT WILL BE TIGHTENING PRODUCING A STRONGER SOUTHERLY FLOW OVER
SOUTH CENTRAL KY THAN PREVIOUSLY FORECAST.

.SHORT TERM (TONIGHT AND FRIDAY)...

...HEAVY RAIN...FLOODING...AND A RISK OF SEVERE WEATHER POSSIBLE
ACROSS THE LOWER OHIO VALLEY OVER THE NEXT 24 HOURS...

AFTERNOON SFC MAP SHOWS A QUASI-STATIONARY BOUNDARY LOCATED ALONG
THE OHIO RIVER BETWEEN KY/IN.  WEAK VORTICITY MAX WAS MOVING THROUGH
THE REGION WHICH HAS BEEN RESPONSIBLE FOR THE FIRST WAVE OF
WIDESPREAD LIGHT TO MODERATE PRECIPITATION TODAY.  FURTHER SOUTH...A
WARM FRONT WAS LOCATED ACROSS FAR SOUTHERN TN WHICH IS SLOWLY MOVING
NORTHWARD. TEMPERATURES ACROSS THE REGION THIS AFTERNOON RANGED FROM
THE MID-UPPER 40S IN THE NORTH TO THE LOWER 50S IN THE SOUTH.

LATEST MODEL DETERMINISTIC MODEL GUIDANCE HAS CHANGED VERY LITTLE
AND IS IN PRETTY GOOD AGREEMENT.  CONSENSUS OF THE DETERMINISTIC
GUIDANCE AGREES WITH TAKING A DEVELOPING SFC LOW OVER TEXAS AND
SWINGING IT NORTHEASTWARD THROUGH ARKANSAS AND INTO KENTUCKY DURING
THE OVERNIGHT HOURS.  AS THIS OCCURS...STRONG LOW-LEVEL JET WILL
TRANSPORT A GOOD AMOUNT OF MOISTURE INTO THE REGION WHICH SHOULD
ALLOW WIDESPREAD SHOWERS AND STORMS TO CONTINUE THROUGH THE EVENING
AND OVERNIGHT HOURS. OVERALL TREND IN THE DETERMINISTIC MODELS HAS
BEEN SLIGHTLY MORE NORTH WITH THE SFC LOW TRACK WHICH RESULTS IN A
HEAVY PRECIP BAND SETTING UP ALONG THE OHIO RIVER.  COMPARING THE
ACTUAL MODEL OUTPUT TO REALITY HAS SHOWN THAT THE MODELS HAVE BEEN A
LITTLE TO FAR NORTH WITH RESPECT TO THEIR HEAVY RAIN BANDS...WHILE
THE ENSEMBLE RUNS HAVE DONE A MUCH BETTER JOB.  THUS...WE PLAN ON
STICKING CLOSER TO THE ENSEMBLE MEAN HERE WHICH RESULTS IN ONLY A
FEW CHANGES BUT MAINTAINS CONSISTENCY WITH OUR PREVIOUS FORECAST.

FOR TONIGHT...WE EXPECT SFC WARM FRONT OVER SOUTHERN TENNESSEE TO
SURGE NORTHWARD THIS EVENING AND GET INTO SOUTHERN KENTUCKY.  HOW
FAR NORTH THIS FRONT GETS IS IN QUESTION.  THE LATEST RUC13 AND HRRR
MODEL RUNS SUGGEST IT COULD GET A LITTLE NORTH OF THE PARKWAYS IN
KENTUCKY.  AFTER THE FRONT MOVES NORTH...SFC COLD FRONTAL BOUNDARY
WILL THEN SWEEP THROUGH FROM THE WEST LATE TONIGHT.  STRONGLY FORCED
LINE OF LINEAR CONVECTION CURRENT ACROSS WEST ARKANSAS AND EAST
TEXAS IS FORECAST TO SLIDE EASTWARD.  THE LATEST RUC...HRRR AND
OPERATIONAL LMK WRF AND EXPERIMENTAL WRF RUNS SHOW THAT THE
NORTHERN THIRD OF THIS LINE MAY IMPACT A PORTION OF SOUTH CENTRAL
KENTUCKY.  WHILE THE INSTABILITY IS RATHER MEAGER...IMPRESSIVE
LOW-LEVEL WINDS AND STRONG SHEAR ARE MORE THAN ADEQUATE TO SUPPORT
AND ISOLATED SEVERE WIND GUST HERE OR THERE ALONG WITH AN ISOLATED
TORNADO.  OVERALL...FEEL THAT DAMAGING WINDS WOULD BE THE PRIMARY
SEVERE THREAT AND THAT THREAT WOULD LIKELY BE LATER THIS EVENING
BETWEEN 25/03-10Z AND GENERALLY SOUTH OF THE PARKWAYS.  FURTHER
NORTH...FEEL THAT SEVERE THREAT IS MUCH MORE LIMITED SIMPLY DUE TO
THE EXISTING RAINFALL AND VERY LOW INSTABILITY.

STILL FEEL THAT MAIN FORECAST CONCERN WILL BE THE HEAVY RAINFALL.
BASED ON THE ENSEMBLE GUIDANCE...STILL THINK THAT AREAS ALONG THE
BG/WKY PARKWAY ARE STILL IN LINE FOR THE AXIS OF HEAVIEST RAINFALL
WITH 3-4 INCHES POSSIBLE.  SOME ISOLATED HIGHER AMOUNTS WILL BE
POSSIBLE THOUGH.  FOR THAT REASON...WILL CONTINUE THE FLASH FLOOD
WATCH THROUGH THE OVERNIGHT HOURS.  HYDROLOGIC CONCERNS ASSOCIATED
WITH THIS RAINFALL IS DISCUSSED BELOW IN THE HYDROLOGY SECTION.

IN ADDITION...STRONG GUSTY GRADIENT WINDS ARE LIKELY TO DEVELOP
TONIGHT.  SUSTAINED WINDS OF 15-25 MPH WITH GUSTS UP OVER 30 MPH
WILL BE POSSIBLE RIGHT BEFORE AND AFTER FRONTAL PASSAGE.
TEMPERATURES WILL CONTINUE TO RISE THIS AFTERNOON AND EVENING WITH
DAYTIME HIGHS PROBABLY OCCURING LATE THIS EVENING.  TEMPERATURES
WILL FALL VERY LATE TONIGHT AS THE COLD FRONT PRESSES THROUGH WITH
LOWS DROPPING INTO THE LOWER-MID 30S IN THE WESTERN HALF WITH UPPER
30S TO THE LOWER 40S IN THE EAST.

FOR FRIDAY...SHOULD SEE A BIT OF POST FRONTAL CLOUD COVER AND
SCATTERED LIGHT SHOWERS OR SPRINKLES DURING THE MORNING HOURS
FRIDAY.  SOME PARTIAL CLEARING MAY DEVELOP LATER IN THE
AFTERNOON...BUT TEMPERATURES WILL REMAIN QUITE COOL WITH CONTINUED
COLD AIR ADVECTION BEING QUITE ACTIVE.  HIGHS ARE LIKELY TO TOP OUT
IN THE LOWER-MID 40S IN THE NORTH WITH MID-UPPER 40S IN THE SOUTH.

.LONG TERM (FRIDAY NIGHT - THURSDAY)...

FRIDAY NIGHT - SATURDAY NIGHT...

THE WEEKEND WILL START OUT ON A DRY NOTE AS HIGH PRESSURE BUILDS IN
BEHIND THE COLD FRONT AND H5 FLOW REMAINS ZONAL. EXPECT PARTLY TO
MOSTLY CLOUDY SKIES DURING THIS TIME AS ONLY MID AND UPPER LEVEL SKY
COVER WILL BE PRESENT. BEST CHANCE FOR MOSTLY CLOUDY SKIES WILL BE
ALONG AND NORTH OF THE OHIO RIVER. LOW TEMPERATURES ON SATURDAY
NIGHT WILL BE QUITE COOL...AROUND 30 DEGREES. SATURDAY WILL SEE THE
RETURN OF SOUTHERLY FLOW WITH HIGHS JUMPING INTO THE 50 TO 55 DEGREE
RANGE. WITH SOUTHERLY FLOW CONTINUING AND INCREASING SKY
COVER...SATURDAY NIGHT WILL YIELD MILD LOW TEMPERATURES IN THE UPPER
30S TO MID 40S.

SUNDAY - MONDAY...

THE END OF THE WEEKEND INTO THE FIRST PART OF THE WEEK WILL BRING AN
ACTIVE PERIOD OF WEATHER AS SOUTHERN STREAM SHORTWAVE ENERGY EJECTS
OUT OF THE SOUTHWEST CONUS AND GREAT PLAINS SURFACE LOW MOVES TOWARD
THE LOWER GREAT LAKES. MODELS STILL DISAGREE ON THE TIMING/PLACEMENT
OF SURFACE LOW...HOWEVER BEST CHANCES FOR COLD FRONTAL PASSAGE
APPEAR TO BE EARLY MONDAY MORNING THROUGH MIDDAY. PREFER THE FASTER
GFS SOLUTION AS IT HAS OTHER MODEL SUPPORT AND IS NOT EVEN AS FAST
AS ITS ENSEMBLE MEAN. DO NOT LIKE THE SLOWER ECMWF AS IT TENDS TO
HOLD ONTO EJECTING SOUTHWEST ENERGY TOO LONG. THEREFORE...EXPECT
SCATTERED RAIN SHOWERS AND ISOLATED THUNDERSTORMS DUE TO ISENTROPIC
LIFT TO INCREASE FROM WEST TO EAST ON SUNDAY. BY SUNDAY
EVENING...EXPECT LIKELY CHANCES FOR RAIN SWEEPING ACROSS THE AREA
AHEAD OF THE COLD FRONT THOUGH THE EVENING HOURS. THIS WILL ALSO BE
THE BEST CHANCE FOR THUNDERSTORMS...SOME OF WHICH COULD BE STRONG TO
SEVERE. A 60 KNOT LOW LEVEL JET IS EXPECTED TO COMBINE WITH SOME
INSTABILITY EVIDENT ON FORECAST SOUNDINGS TO CREATE A DAMAGING WIND
THREAT. HOWEVER...AS IS GENERALLY THE CASE WITH STRONG DYNAMIC/LOW
INSTABILITY SITUATIONS...WILL THE STRONG WINDS ALOFT BE ABLE TO MIX
DOWN TO THE SURFACE THROUGH A SOMEWHAT STABLE LAYER. THE BEST CHANCE
FOR THIS TO OCCUR WILL BE IN ANY THUNDERSTORM. CANNOT RULE OUT
ISOLATED TORNADOES EITHER AS CONVECTIVE MODE WILL LIKELY BE IN THE
QLCS FORM. SPC HAS OUTLOOKED AREAS JUST TO THE WEST WITH THIS
SYSTEM...WITH THE MENTION OF POTENTIALLY EXPANDING AN OUTLOOK
EASTWARD WITH FUTURE UPDATES. STAY TUNED. ALSO OF CONCERN WILL BE
THE POTENTIAL FOR HEAVY RAIN LATE SUNDAY NIGHT THROUGH EARLY MONDAY
AS ANOTHER INCH TO POSSIBLY 2 INCHES OF RAINFALL COULD FALL OVER A
SHORT PERIOD OF TIME. WITH OUR RECENT RAINS...FLASH FLOODING WILL
ALSO BE A THREAT.

COLD FRONT LOOKS TO SLIDE THROUGH THE AREA BY MONDAY AFTERNOON WITH
HIGH PRESSURE BUILDING BACK INTO THE REGION BEHIND THE FRONT BY
MONDAY NIGHT. WILL HAVE TO WATCH NON-CONVECTIVE WIND POTENTIAL ON
MONDAY AFTERNOON VERTICAL THETA SURFACES ON TIME HEIGHT CROSS
SECTIONS WE SHOULD BE ABLE TO MIX INTO A 40 TO 50 KNOT LAYER OF WIND
JUST ABOVE THE SURFACE. ADDING TO THE WIND POTENTIAL...A DRY SLOT
HAS POTENTIAL TO WORK INTO THE AREA IN THE AFTERNOON WHICH COULD
INCREASE MIX DOWN POTENTIAL.

TEMPERATURES ON SUNDAY WILL WARM NICELY INTO THE LOW TO MID 60S AS
WE STAY IN THE WARM SECTOR AND STRONGER SOUTHERLY FLOW ADDS A WAA
COMPONENT. SUNDAY NIGHT WILL ALSO BE MILD WITH LOWS ONLY DROPPING
INTO THE LOWER 50S. MONDAY WILL LIKELY FEATURE AN EARLY HIGH
TEMPERATURES WITH THE MERCURY DROPPING OFF LATER IN THE DAY AS
STRONG COLD FRONT WORKS THROUGH AND CAA COMMENCES.

MONDAY NIGHT - THURSDAY...

SURFACE HIGH PRESSURE WITH ZONAL FLOW ALOFT WILL DOMINATE THROUGH
TUESDAY NIGHT WITH FLOW TRANSITIONING TO A MORE NORTHWEST PATTERN BY
MID WEEK. EXPECT MUCH COOLER LOW TEMPERATURES MONDAY NIGHT THROUGH
WEDNESDAY NIGHT WITH THE MERCURY BOTTOMING OUT IN THE 30 TO 35
DEGREE RANGE. HIGHS SHOULD GRADUALLY MODERATE TO THE FROM THE LOW
50S ON TUESDAY TO THE MID AND UPPER 50S ON THURSDAY. THIS PORTION OF
THE FORECAST IS EXPECTED TO REMAIN DRY ASIDE FROM LINGERING SHOWERS
EAST OF I 65 ON MONDAY EVENING.

.HYDROLOGY...

* FORECAST OVERVIEW AND RAINFALL -

LATEST SUITE OF DETERMINISTIC AND ENSEMBLE GUIDANCE HAS NOT CHANGED
TOO MUCH BETWEEN THE 24/06Z AND 25/12Z RUNS.  BOTH THE OPERATIONAL
GFS AND NAM RUNS CONTINUE TO SHOW AN AXIS OF HEAVY PRECIPITATION
FALLING JUST ALONG AND SOUTH OF THE OHIO RIVER.  COMPARING THE
MODELS TO REALITY HAS SHOWN THE MODELS HAVE BEEN A LITTLE TOO FAR
NORTH WITH THEIR AXIS OF HEAVY PRECIPITATION.  THE 24/12Z GFS
ENSEMBLE AND 24/09Z SREF ENSEMBLE MEANS ARE A BIT MORE TO THE
SOUTH...JUST ALONG AND NORTH OF THE BLUEGRASS AND WESTERN KY
PARWKAYS.  SINCE PRECIPITATION SEEMS TO BE VERIFYING CLOSER TO THE
ENSEMBLES...WE ARE LEANING ON KEEPING OUR AXIS OF HEAVIEST PRECIP
ORIENTED IN CENTRAL KY...NEARLY PARALLEL TO THE BLUEGRASS AND
WESTERN KY PARKWAYS.  IN GENERAL...THIS IS NOT MUCH OF A CHANGE IN
THE PREVIOUS FORECAST...BUT MAYBE JUST A HAIR NORTH OF WHERE WE
FORECASTING BEFORE.

RAINFALL THIS AFTERNOON AND EVENING WILL BE GENERALLY BE ON THE
LIGHT SIDE WITH LESS THAN 0.50 INCHES.  HEAVY RAINS WILL MOVE BACK
IN LATER TONIGHT AND DURING THE OVERNIGHT HOURS ACROSS CENTRAL
KENTUCKY.  STORM TOTAL RAINFALL OF 3-5 INCHES LOOKS LIKELY IN THE
HEAVY RAIN CORRIDOR.  ELSEWHERE 2-4 INCHES OF RAINFALL STILL LOOKS
LIKELY THROUGH FRIDAY.

* BASINS OF CONCERN -

THE FOLLOWING BASINS ARE LIKELY TO EXPERIENCE HYDROLOGIC ISSUES OVER
THE NEXT 24-48 HOURS...GREEN...BARREN...ROUGH RIVER...ROLLING FORK
AND LICKING RIVER BASINS.

ON THE BARREN RIVER...DRAKES CREEK NEAR ALVATON WILL LIKELY GO INTO
FLOOD ON FRIDAY.  AM EXPECTING TO SEE A RISE AT BOWLING GREEN...BUT
NOT THAT MUCH. ON THE GREEN RIVER...BROWNSVILLE WOODBURY AND
ROCHESTER ARE LIKELY TO HIT FLOOD STAGE ON FRIDAY.  OVER ON THE
ROUGH RIVER...DUNDEE IS CURRENTLY RISING IS EXPECTED GO INTO FLOOD
ON FRIDAY.

OVER ON THE ROLLING FORK RIVER...WE SHOULD START TO SEE THE RIVER
RISE AT BOSTON LATER THIS AFTERNOON AND EVENING WITH A SHARP RISE
OCCURING OVERNIGHT.  IT WILL LIKELY GO INTO FLOOD FRIDAY AFTERNOON
AND MAY GET CLOSE TO MODERATE FLOOD BY THE WEEKEND.

ON THE KENTUCKY RIVER...DIX DAM HAS HAD THEIR GATES OPEN ALLOWING
HERRINGTON LAKE TO DRAIN OFF A BIT.  BASED ON OUR CALCULATIONS...WE
FIGURE THAT THEY CAN HANDLE ABOUT 3 INCHES OF RAIN...WHICH IS VERY
CLOSE TO WHAT WE'RE FORECASTING.  THE RELEASE OF WATER AT THE DAM
PLUS THE RAINFALL WILL LEAD TO RISES ALONG THE KENTUCKY RIVER AT
HIGH BRIDGE AND FRANKFORT.  AT THIS TIME WE EXPECT THESE STATIONS TO
STAY BELOW ACTION STAGE...BUT THIS COULD CHANGE OVER THE NEXT FEW
DAYS.

FURTHER EAST...WE'LL LIKELY SEE RISES ON THE LICKING RIVER AT
CYNTHIANA AND BLUE LICKS SPRINGS.  ALSO WILL LIKELY SEE SOME RISES
OVER ON STONER CREEK IN PARIS KY AS WELL.  CYNTHIANA AND BLUE LICKS
SPRINGS WILL LIKELY HIT FLOOD STAGE ON FRIDAY AS WELL.

WHILE WE WILL DRY OUT OVER THE WEEKEND...MUCH OF THE WATER IN THE
RIVERS FEEDING THE OHIO WILL CAUSE THE OHIO TO SEE A STEADY RISE
OVER THE WEEKEND.  A SECONDARY WEATHER SYSTEM EARLY NEXT WEEK MAY
RESULT IN ADDITIONAL HEAVY RAINFALL WHICH COULD PUSH SEVERAL POINTS
ALONG THE OHIO INTO FLOOD.  MOST LIKELY WE WOULD EXPECT TO SEE TELL
CITY AND CANNELTON HIT FLOOD STAGE.

IF YOU LIVE IN A FLOOD PRONE AREA ALONG ANY CREEK OR STREAM IN
CENTRAL KENTUCKY...KEEP ABREAST OF THE WATER LEVELS AND BE PREPARED
TO SEEK HIGHER GROUND IF FLOODING OCCURS.

* SIGNIFICANT CHANGES -

BASED ON THE DATA ABOVE...WE HAVE ONLY MADE SMALL CHANGES TO OUR
HEAVY RAINFALL AXIS.  IN GENERAL...WE STILL FEEL IT WILL BE CENTERED
ACROSS CENTRAL KENTUCKY...WITH A SLIGHT NORTHWARD ADJUSTMENT NOTED.

* CONFIDENCE LEVEL -

CONFIDENCE IS VERY HIGH FOR REACHING ACTION/FLOOD STAGE FOR GAUGES
ALONG PORTIONS OF THE GREEN/BARREN/ROUGH RIVER/ROLLING FORK AND THE
LICKING RIVER BASINS.

CONFIDENCE IS MODERATE FOR REACHING ACTION/FLOOD STAGE FOR GAUGES
ALONG THE KENTUCKY RIVER.

.AVIATION (00Z TAF ISSUANCE)...

SURFACE LOW NOW OVER CENTRAL ARKANSAS...DEEPENING...AND ON ITS WAY
TO CENTRAL KENTUCKY. A WARM FRONT AHEAD OF THE LOW IS PROVIDING
ENOUGH LIFT FOR WIDESPREAD RAINS...BRINGING LOW CIGS AND VSBYS. THE
LOW SHOULD BE OVER CENTRAL KENTUCKY SOMEWHERE BETWEEN KSDF AND KBWG
JUST AFTER 06Z. AS STORMS MOVE THROUGH WITH THE COLD FRONT AHEAD OF
THE LOW...WILL THE GUSTIEST WINDS AT THE KBWG SITE...WHICH WILL BE
DEEPER INTO THE WARM AIR AHEAD OF THE SYSTEM.

STORMS SHOULD END BEFORE DAYBREAK...BUT MAY HAVE LINGERING RAIN
KEEPING VSBYS DOWN. MODELS INDICATED RESIDUAL LOW LEVEL MOISTURE
THAT WILL KEEP CIGS DOWN LIKELY THROUGH THE MORNING HOURS.

THE EXACT LOCATION OF THE LOW WILL MAKE A BIG DIFFERENCE IN THE
WINDS AT THE TAFS...SO HAVE PUT IN BEST ESTIMATE FOR EACH OF THE
SITES. THE STRENGTH OF THE GRADIENT SHOULD BE ENOUGH TO GENERATE
GUSTY CONDITIONS THROUGH THE NIGHT...EVEN OUTSIDE OF THUNDERSTORMS
COMING.
