Area forecast discussion, Jun 5, 6:19 AM CDT, 2 hours 17 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
619 AM CDT SUN JUN 5 2011

.DISCUSSION...
ISSUED 215 AM CDT SUN JUN 5 2011

EARLIER THUNDERSTORM ACTIVITY HAS MOVED WELL EAST OF THE STATE.
HAVE HAD A BIT OF CLEARING OVER THE AREA...WHICH HAS LED TO SOME
PATCHY DENSE FOG BEING REPORTED NEAR GALESBURG. THE HIGH-
RESOLUTION MODELS THE LAST 24 HOURS HAVE BEEN HINTING AT SOME SORT
OF MCS DEVELOPMENT OVER MISSOURI AND IOWA AROUND THE CURRENT
TIME...AS THE LOW LEVEL JET OVER THAT AREA INCREASES TO AROUND
30-40 KNOTS. INDEED...SOME SHOWERS AND STORMS HAVE BEEN FIRING
FROM SOUTHEAST IOWA INTO CENTRAL MISSOURI THE LAST HOUR OR TWO.

THE PRIMARY FORECAST ISSUE INVOLVES CONVECTIVE DEVELOPMENT THROUGH
MONDAY...WITH THE PERSISTENT HEAT AND HUMIDITY ALSO PLAYING A
LARGE ROLE.

SHORT TERM...TODAY THROUGH TUESDAY...

EXACT PLACEMENT OF SYNOPTIC BOUNDARY HAS BEEN COMPLICATED BY THE
OUTFLOWS FROM THE EARLIER THUNDERSTORMS...BUT APPEARS TO BE RE-
ESTABLISHING ITSELF ROUGHLY FROM DANVILLE TO JUST SOUTH OF
PITTSFIELD...THEN EXTENDING WESTWARD TO NEAR KANSAS CITY.
CONVECTION TO OUR WEST SHOULD CONTINUE TO INCREASE THE NEXT FEW
HOURS...BUT TAKE MORE OF A SOUTHEAST CURVE AS THE UPPER RIDGE AXIS
SHIFTS TO THE WEST. WILL GO WITH BROAD 30-40 PERCENT RAIN CHANCES
TODAY. SEVERE WEATHER THREAT WILL BE COMPLICATED DUE TO THE
BOUNDARIES AND UNEVEN DESTABLIZATION...BUT WOULD MOST LIKELY BE
ACROSS THE SOUTHWEST HALF OF THE CWA.

00Z MODELS INDICATING MOST LIKELY MCS DEVELOPMENT TONIGHT SHOULD
BE TO OUR NORTH. WITH THE UNCERTAINTY FROM THE AFTERNOON
CONVECTION...WILL LINGER SLIGHT CHANCE POPS ACROSS THE CWA INTO
THIS EVENING...AND CONFINE THEM ALONG AND NORTH OF I-74
OVERNIGHT. WITH UPPER RIDGING DRIFTING BACK OVERHEAD...STORM TRACK
WILL BE TO OUR NORTH AND THUS DRY CONDITIONS ARE LIKELY MONDAY
INTO TUESDAY.

TEMPERATURE-WISE...HIGHS TODAY WILL BE A GOOD DEAL LOWER THAN
SATURDAY...BUT STILL IN THE MID TO UPPER 80S. HIGHS IN THE LOWER
90S LIKELY AGAIN ON MONDAY. MID 90S SHOULD BE WIDESPREAD OVER THE
CWA ON TUESDAY...WITH HEAT INDEX VALUES AROUND 100 DEGREES.

LONG TERM...WEDNESDAY THROUGH SUNDAY...

UPPER RIDGING TO BECOME MORE AMPLIFIED ALONG THE EAST COAST
BEGINNING ON WEDNESDAY. LONGER RANGE MODELS CONTINUE TO SUPPORT A
TREND FOR THURSDAY/FRIDAY SIMILAR TO WHAT IS CURRENTLY
HAPPENING...WITH THE RIDGE FLATTENING AND A COLD FRONT BECOMING
STATIONARY ON TOP OF IT. GFS/ECMWF/CANADIAN MODELS ARE IN GOOD
AGREEMENT IN THE ARRIVAL OF THE FRONT IN OUR AREA ON THURSDAY. THE
CANADIAN IS MORE AGGRESSIVE IN PUSHING IT ALL THE WAY THROUGH BY
FRIDAY MORNING...WHILE THE OTHER MODELS LINGER IT IN OUR AREA INTO
THE FIRST PART OF THE WEEKEND. THE EXISTING CHANCE POPS THURSDAY
THROUGH FRIDAY STILL APPEAR REASONABLE...AND POPS FRIDAY
NIGHT/SATURDAY MAY NEED TO BE BOOSTED IN LATER FORECAST PACKAGES.

GEELHART

.AVIATION...
ISSUED 618 AM CDT SUN JUN 5 2011

CLUSTERS OF STRONG TO SEVERE THUNDERSTORMS HAVE BEEN PUSHING
ACROSS WEST CENTRAL ILLINOIS THE LAST COUPLE HOURS. WORST OF THE FIRST
BATCH SHOULD JUST MISS KSPI TO THE SOUTHWEST AS THE FORECAST
PERIOD BEGINS...BUT A SECOND BATCH MAY ARRIVE AROUND 1330-1400Z IF
IT HOLDS TOGETHER. KPIA WILL ALSO SEE A CLOSE PASS FROM THE SECOND
BATCH OF STORMS. HAVE GONE WITH TEMPO GROUPS FOR TSRA AT THESE
SITES AS WELL AS KBMI...BUT HELD ONTO VCTS FURTHER EAST FOR NOW...AS
SOME OF THE HIGH-RESOLUTION MODELS SHOWED A MARKED DECREASE IN
COVERAGE AS THE STORMS REACH THAT FAR EAST. THREAT OF CONVECTIVE
ACTIVITY APPEARS TO BE MINIMAL BY ABOUT 20Z. VFR CONDITIONS
EXPECTED AFTERWARD THROUGH ABOUT 06Z...WITH SOME POTENTIAL MVFR
VISIBILITIES LATE IN THE PERIOD.
