AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
1218 AM CDT MON APR 4 2011

.DISCUSSION...
ISSUED 915 PM CDT SUN APR 3 2011

STORMS ARE DEVELOPING ALONG THE COLD FRONT...SINCE THAT IS THE
ONLY PORTION OF THE AIRMASS THAT IS UNSTABLE ENOUGH TO
THUNDERSTORMS. OUR 00Z SOUNDING WAS QUITE CAPPED WITH LIMITED
MOISTURE. STORMS SHOULD BECOME LESS SEVERE IN THAT TYPE OF
AIRMASS. STORMS MAY CONTINUE TO PERSIST ACROSS OUR AREA...BUT
SEVERE REPORTS SHOULD BECOME LESS NUMEROUS. HAIL WILL BE THE MAIN
THREAT...WITH DAMAGING WINDS POSSIBLE.

THE SEVERE THUNDERSTORM WATCH GOES UNTIL 2 AM...AND STORM
EVOLUTION WILL DICTATE WHETHER ANOTHER WATCH WILL BE NEEDED BEYOND
THAT. STRATIFORM RAIN MAY LINGER FOR A TIME BEHIND THE FRONT...BUT
IT WILL NOT BE WIDESPREAD BASED ON UPSTREAM DRY INTRUSION BEHIND
THE FRONT.

TEMPS WILL REMAIN WARM FOR MUCH OF THE NIGHT DUE TO SOUTHERLY
WINDS CONTINUING FOR MUCH OF THE NIGHT AHEAD OF THE COLD FRONT.
EVEN AFTER THE FRONT PASSES...COLD AIR WILL LAG BEHIND THE FRONT
ENOUGH THAT LOW TEMPS WILL NOT BE AFFECTED AS SIGNIFICANTLY. WILL
KEEP THE MILD LOWS FOR TONIGHT. WE MAY EVEN NEED TO BUMP THEM UP A
FEW DEGREES FROM THE CURRENT FORECAST.

.AVIATION...
ISSUED 1218 PM CDT SUN APR 3 2011...FOR THE 06Z TAFS

THE LINE OF STORMS HAS GENERALLY DIMINISHED AS IT HAS ARRIVED IN
OUR WESTERN CWA. WILL STILL KEEP A 2 HOUR WINDOW OF TEMPO FOR MVFR
CIGS/VIS AS THE COLD FRONT PROGRESSES EAST. THE LINE IS BROKEN
INTO SEGMENTS...SO CONFIDENCE IS NOT HIGH THAT EACH SITE WILL
REACH THAT MVFR CRITERIA. THE STRONGEST STORM APPROACHING THE AREA
IS EXPECTED TO AFFECT SPI BY 0630Z AND DEC BY 0745Z...IF IT HOLDS
TOGETHER. STRONG WINDS WOULD BE THE MAIN HAZARD...WITH HAIL POSSIBLE.

WINDS BEHIND THE FRONT ARE LOOKING STRONGER THAN PREVIOUSLY
FORECAST. WE COULD SEE WINDS OVER 30 KT AT ALL TAF SITES BY 12Z-
15Z...ESPECIALLY INCREASING AS MIXING EXTENDS INTO THE LOWER
TROPOSPHERE.

MVFR CLOUDS MAY LINGER THROUGH MUCH OF THE DAY...BUT PRECIP
SHOULD DIMINISH BY 17Z-18Z. WE KEPT VCSH TOMORROW MORNING...BUT
CONFIDENCE IS LOW THAT MEASURABLE PRECIP WILL OCCUR VERY FAR BEHIND
THE LINE OF STORMS.

NORTHWEST WIND GUSTS SHOULD DIMINISH BELOW 20KT AFTER 00Z MONDAY EVENING.

.PREV DISCUSSION...
ISSUED 205 PM CDT SUN APR 3 2011

SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT

MAIN FORECAST CONCERN THIS PERIOD WILL BE WITH THE SEVERE WEATHER
POTENTIAL THIS EVENING AS THE COLD FRONT PUSHES INTO OUR AREA.

SHORT TERM MODELS IN DECENT AGREEMENT WITH RESPECT TO THE TIMING
OF THE COLD FRONTAL PASSAGE ACRS THE FORECAST AREA LATER THIS
EVENING. FRONT OVER CENTRAL IOWA EARLY THIS AFTERNOON IS FORECAST
TO APPROACH THE MISSISSIPPI RIVER BY 00Z AS AN AREA OF LOW PRESSURE
TRACKS INTO NE IOWA/SW WISCONSIN. STRONG PRESSURE GRADIENT AHEAD OF
FRONT HAS PRODUCED 40 TO 50+ MPH GRADIENT WINDS THIS AFTERNOON AND
EXPECT THOSE TO SLOWLY DIMINISH AS THE FRONT APPROACHES...ESP ACRS
THE NORTHWEST LATER THIS EVENING. HI-RES MODEL SOLUTIONS CONTINUE
TO SUGGEST CONVECTIVE INITIATION RIGHT ALONG THE COLD FRONT EARLY
THIS EVENING OUT TO OUR NORTHWEST WHERE THE CAP WILL HAVE WEAKENED
CONSIDERABLY.

CONVECTIVE SIMULATIONS FROM BOTH THE 4KM WRF AND NCEP'S HI-RES
ARW AND NMM MODELS INDICATE CONVECTIVE MODE WILL EVOLVE FROM
DISCRETE SUPERCELLS ACRS NRN MO INTO EASTERN IOWA INTO MORE OF A
QUASI-LINEAR CONVECTIVE SYSTEM LATER THIS EVENING AS IT HEADS INTO
OUR AREA. VERY IMPRESSIVE LOW LEVEL (MOSTLY UNIDIRECTIONAL) SHEAR
PROFILES AHEAD OF THE SYSTEM SUGGESTS THE MAIN THREAT WOULD BE
FROM STRAIGHT LINE WIND DAMAGE AND LARGE HAIL AS FORECAST SOUNDINGS
CONTINUE TO INDICATE STEEP MID LEVEL LAPSE RATES PRESENT ACRS THE
FORECAST AREA THIS EVENING. LOCATIONS ALONG AND NW OF THE IL RIVER
HAVE THE HIGHER PROBABILITIES OF ISOLD TORNADOES EARLY THIS EVENING
AS THEY WILL BE CLOSER TO THE SFC WAVE WITH A MORE BACKED LOW
LEVEL WIND PROFILE. OPERATIONAL NAM PRECIP WATER VALUES UP TO 1.4
INCHES BY MID AND LATE EVENING...WELL ABOVE NORMAL FOR THIS TIME
OF YEAR. NAM ALSO INDICATING A SECONDARY WAVE OF LOW PRESSURE WILL
MOVE UP THE FRONT LATER THIS EVENING WHICH WILL TEND TO SLOW THE
FORWARD PROGRESS OF THE COLD FRONT OVERNIGHT. IN ADDITION...500 MB
TROF AXIS AND ADDITIONAL LIFT STILL WELL WEST OF THE FORECAST AREA
LATE TONIGHT SUGGESTING A CONTINUATION OF THE HIGHER POPS WELL INTO
MONDAY MRNG NW WITH THE HIGHEST POPS CLOSER TO THE FRONT OVER SE IL.

FRONT IS EXPECTED TO PASS OFF TO OUR EAST BY AFTERNOON WITH A
RENEWED THREAT FOR SEVERE WEATHER JUST OFF TO OUR EAST AND SOUTH
TOMORROW AFTN. UPPER LEVEL TROF IS THEN FORECAST TO SHIFT OFF TO
OUR EAST MONDAY NIGHT TAKING ANY LINGERING RAIN CHANCES ACRS OUR
SE WITH IT. QUIETER WEATHER TO SETTLE INTO THE MIDWEST FOR TUESDAY
AND WEDNESDAY AND HIGH PRESSURE BUILDS INTO THE REGION. NEXT
SHORTWAVE AND FRONTAL BOUNDARY FORECAST TO APPROACH THE AREA
DURING THE DAY WEDNESDAY BUT MOISTURE AVAILABILITY AHEAD OF THE
SYSTEM LOOKS MEAGER AT BEST.

NOT A GREAT DEAL OF TEMP DROP OFF EXPECTED THRU MOST OF THE
EVENING AS THE FRONT WILL REMAIN OUT TO OUR WEST. WILL SIDE WITH
THE WARMER GUID NUMBERS...ESP ACRS THE EAST AND SOUTH WHERE THE
FRONT WILL NOT ARRIVE UNTIL MONDAY MORNING. HIGH TEMPS ON MONDAY
WILL BE DURING THE MORNING HOURS...WITH STEADY OR SLOWLY FALLING
TEMPS THEREAFTER AS STRONG LOW LEVEL COLD ADVECTION AND WIDE SPREAD
CLOUD COVER SHOULD HELP TO KEEP TEMPS FROM MAKING MUCH OF A
RECOVERY...ESP ACRS THE WEST AND NORTH.

WILL CONTINUE TO HANG ON TO THE WIND ADVSY INTO EARLY THIS EVENING
BUT AS MENTIONED ABOVE...AS THE FRONTAL BOUNDARY APPROACHES FROM
THE WEST LATER THIS EVENING...EXPECT WINDS TO SLOWLY DIMINISH...ESP
ACRS THE WEST AND NORTH.

LONG TERM...THURSDAY THROUGH SUNDAY

RATHER ACTIVE PATTERN DURING THIS PERIOD WITH MODEL SOLUTIONS
SHOWING SOME SIGNIFICANT SPREAD AFTER THURSDAY WITH RESPECT TO
THE NEXT TROF DEEPENING IN ACRS THE WESTERN PORTION OF THE COUNTRY.
PATTERN EVOLVING INTO A SOUTHWESTERLY FLOW ALOFT DURING THIS
PERIOD WITH SEVERAL SHORTWAVES FORECAST TO SHIFT NE OUT OF THE
LONGWAVE TROF POSITION. TIMING IS HANDLED DIFFERENTLY BY THE
MEDIUM RANGE MODELS AS WE HEAD TOWARDS THE END OF THE WORK WEEK
WITH THE MORE AMPLIFIED...SLOWER SOLUTION...DEPICTED ON THE LATEST
ECMWF LOOKING MORE REASONABLE. EVEN WITH THAT SOLUTION...WILL HAVE
TO HOLD ON TO AT LEAST LOW CHANCE POPS DURING THIS PERIOD AS THE
COLD FRONT THAT IS FORECAST TO PUSH ACRS THE FORECAST AREA LATE
ON WEDNESDAY WILL BE CLOSE TO OUR AREA INTO NEXT WEEKEND...ENHANCING
THE CHANCES FOR SHOWERS AND THUNDERSTORMS AS THE SHORTWAVES KICK
OUT OF THE SOUTHWEST TROF. WITH THE TRANSITION TO A SOUTHWESTERLY
FLOW ALOFT...TEMPS WILL BE CLOSE TO OR ABOVE NORMAL DURING THIS
PERIOD.
