What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Louisville, KY wrote its last area forecast discussion before this severe thunderstorm warning went out at May 22, 12:06 PM CDT, 1 hour 27 minutes earlier.

Area forecast discussion, May 22, 12:06 PM CDT, 1 hour 27 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
106 PM EDT SUN MAY 22 2011

...UPDATED AVIATION DISCUSSION...

...FORECAST UPDATE...

THE DENSE FOG ADVISORY HAS BEEN CANCELLED THIS MORNING AS MUCH OF
THE FOG HAS LIFTED THIS MORNING WITH THE DAYTIME HEATING. A FEW
SHOWERS AND THUNDERSTORMS HAVE DEVELOPED THIS MORNING JUST TO THE
WEST OF THE FORECAST AREA AND WILL MOVE INTO THE REGION SOON. THE
LATEST HRRR RUNS HAVE A FAIRLY GOOD HANDLE ON CURRENT SHOWER/STORM
DEVELOPMENT. THIS MODEL SHOWS SCATTERED CONVECTION DEVELOPING ACROSS
MUCH OF THE FORECAST AREA LATE THIS MORNING SO HAVE RAISED POPS FOR
THIS MORNING INTO THE CHANCE CATEGORY FOR ALL BUT THE NORTHEASTERN
QUARTER OF THE FORECAST AREA. OTHERWISE THE FORECAST IS IN PRETTY
GOOD SHAPE. UPDATES ARE ALREADY OUT.

.SHORT TERM (TODAY AND TONIGHT)...

WELL...COMPLICATED SUNDAY AM FCST.  1ST OFF...T/TD SPREADS ARE IN
THE 0-4 DEGREE SPREAD RANGE WITH SFC DEW POINTS IN THE MID 60S.
LIGHT SWLY WINDS ARE ON TOP OF GENLY CLR SKIES AND EARLIER SAT
EVENING RAINFALL OF 1/4 INCH TO NEARLY 1 INCH AROUND LOUISVILLE. THE
11-3.9 MICRON SATELLITE LOOP SHOWING RAPID INCREASE IN FOG OVER SRN
INDIANA. AREAS OF DENSE FOG HAVE DROPPED BWG/GLW TO IFR ALREADY AND
SEVERAL WEB CAMS SHOWING THICKENING FOG.  HAVE ISSUED A SPS TIL 4 AM
AND WILL REPLACE THIS WITH A DENSE FOG ADVISORY FOR WESTERN 2/3 OF
THE AREA...BASICALLY WEST OF I75.  HOWEVER...MAY MAKE CHANGES TO
AREA JUST BEFORE PRESS TIME AND CHECK MICROSCALE OBS AND WEB CAMS.
RIGHT NOW FEEL 100% CONFIDENT FOR NPW OVER SRN INDIANA.

AFTER THE FOG BURNS OFF...THE ATTENTION TURNS TO CONVECTIVE
CHANCES.  MODELS INITIALIZATION IS EXTREMELY POOR...ESPECIALLY WITH
EARLIER MCS OVER ARKANSAS. THE MCS CONTINUES TO WEAKEN AND WILL
PROVIDE A BIT OF A MORNING SHIELD ABV THE FOG WHICH WILL BE BURNING
OFF BY 14Z. LLVL JET OVER AR BRINGING SUFFICIENT WAA TO INITIATIVE
ISOL CONVECTION TO OUR SOUTH...LIKE NEW CELL OVER NE MS...SO WILL
KEEP SLGT CHANCE POPS FOR BOTTOM 2 TIERS OF COUNTIES FOR MID TO LATE
MORNING.

SOUNDINGS SHOWING INCREASING INSTABILITY THIS AFTERNOON...DESPITE
CLOUD COVER...WITH LIS -4 TO -6 AND CAPES AROUND 1000 J/KG. THE MOST
STRIKING PART OF SEVERAL DIFFERENT MODEL SOUNDINGS IS THE RAPID
INCREASE OF PWATS...BUT WITH MID LEVEL WINDS OF 30-35 KTS...SO
STORMS THAT DO FIRE FROM CONVECTIVE HEATING WILL MOVE ALONG. HAVE
KEPT POPS IN THE 30-40% RANGE WITH NEXT POSSIBILITIES WEST OF I 65
FROM 19-03Z.

OVERNIGHT IS EVEN MORE LESS CLEAR...WITH SEVERAL MODELS TRYING TO
BRING A MCS IN FROM THE WEST FROM S/WAVE AHEAD OF THE H5 LOW TOWARDS
12Z...BUT CONFIDENCE IS QUITE LOW.  FOR NOW KEEP POPS OVERNIGHT AND
WILL LET DAY SHIFT DELVE INTO THIS.

HAVE GONE ABV GUIDANCE BY A COUPLE OF DEGREES BUT DROPPED LOWS A
DEGREE OR TWO FROM PREVIOUS FCST. SSW WINDS WILL BE INCREASING TO
10-18 MPH THIS AFTN...BUT TEMPS WILL BE INHIBITED BY MID AND HIGH
LEVEL CLOUDS. IT APPEARS THERE WILL BE A 1-3 HOURS WINDOW OF
OPPORTUNITY WHERE SOME SUN WILL ALLOW TEMPS TO START CLIMBING
TOWARDS THE MAGIC CONVECTIVE TEMP OF 83-85.

.LONG TERM (MONDAY - SATURDAY)...

MONDAY THROUGH WEDNESDAY

PERSISTENT SUMMER-LIKE TEMPERATURES WILL CONTINUE EACH DAY. MOIST
AIRMASS IN PLACE WITH PRECIPITABLE WATERS ABOVE NORMAL. EXPECT
MULTIPLE SHORTWAVES TO CROSS REGION IN BROAD SOUTHWESTERLY FLOW WITH
UPPER LOW...CURRENTLY OVER SOUTH DAKOTA...FORECAST TO MOVE INTO THE
GREAT LAKES MONDAY AND ANOTHER UPPER LOW FORECAST TO MOVE IN AND
REPLACE IT WEDNESDAY OVER THE CENTRAL PLAINS. GIVEN THE DIFFICULTY
IN TIMING THESE SMALL SCALE FEATURES WILL MAINTAIN CHANCE-RANGE POPS
THROUGH THIS PERIOD. AS OF THIS TIME...AREA MODEL SOUNDINGS LOOK
LIKE THEY PRESENT THE BEST SEVERE THREAT MONDAY AFTERNOON. LAPSE
RATES ARE STEEP WITH MID-LEVEL TEMPS FAIRLY COOL...THE UPPER LOW
WILL BE ON CLOSEST APPROACH OVER THE GREAT LAKES...AND EXPECTED
SURFACE TEMPERATURES IN THE MID 80S. HOWEVER...SHOULD ONE OF THESE
WAVES BRING PRECIP IN THE MORNING...THE THREAT FOR SEVERE WEATHER
COULD BE SHORT-CIRCUITED DEPENDING ON HOW QUICKLY THE DEBRIS CLOUDS
GET OUT AND ALLOW HEATING.

OVERALL RAINFALL TOTALS FOR THIS PERIOD WILL RANGE FROM 1-2 INCHES
WITH ISOLATED HIGHER AMOUNTS.

THURSDAY AND BEYOND

THE SECOND UPPER LEVEL LOW MENTIONED ABOVE WILL MOVE INTO THE OHIO
VALLEY. THIS SHIFT SHOULD FORCE THE FRONTAL BOUNDARY TO MOVE THROUGH
THE REGION. WITH MORE DYNAMIC FORCING IN PLACE...SOME SEVERE STORMS
ARE STILL POSSIBLE AHEAD OF THIS FRONT. THERE ARE STILL SOME TIMING
DIFFERENCES BETWEEN THE MODELS ABOUT HOW QUICKLY THESE FEATURES WILL
MOVE THROUGH. SHOULD THE SLOWER MODELS WIN OUT...ANY DRYING BEHIND
THEM WOULD BE BRIEF AS YET ANOTHER UPPER LOW DROPS IN FROM THE
PACIFIC NORTHWEST.

&&

.AVIATION (18Z TAF ISSUANCE)...

MULTIPLE WAVES OF ENERGY WILL ROTATE AROUND AN UPPER LEVEL LOW WHICH
WILL TRACK FROM SRN MN ACROSS THE GREAT LAKES THROUGH THE TAF
PERIOD. THE MAIN CHALLENGE THIS WILL POSE IS FOR THE FORECASTING OF
PERIODS OF SHOWERS AND STORMS THAT MAY IMPACT THE TERMINALS. THE
GENERAL CONSENSUS AMONG THE MODELS IS THAT SCATTERED STORMS WILL
DEVELOP AND MOVE ACROSS CENTRAL KENTUCKY THIS AFTERNOON. WITH THE
SCATTERED NATURE OF THESE STORMS WILL MENTION ONLY A CB GROUP AT SDF
AND LEX AS CERTAINTY OF STORM DEVELOPMENT IN THE VICINITY OF THE
TERMINAL IS NOT VERY HIGH. WITH STORMS ALREADY DEVELOPING NEARER TO
BWG WILL MENTION VCTS THERE.

IT LOOKS LIKE THERE WILL BE A BREAK IN PRECIPITATION THIS EVENING
BEFORE STORMS DEVELOP AGAIN AFTER MIDNIGHT. IN GENERAL FLYING
CONDITIONS WILL BE VFR OUTSIDE OF ANY THUNDERSTORMS.
