AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
638 AM CDT MON JUL 13 2015

.SYNOPSIS...
ISSUED AT 250 AM CDT MON JUL 13 2015

QLCS IN WI IS REINVIGORATING AS THE UPPER LEVEL JET PUSHING INTO
THE AREA STRENGTHENS THE MID-LEVEL FLOW AND SHEAR PROFILE UP
THERE. RADAR INDICATES SOUTHWARD-MOVING WESTERN PART OF THE LINE
IS BECOMING OUTFLOW DOMINATED WHICH SHOULD LESSEN OUR SHORT TERM
SEVERE THREAT. OTHERWISE THE CWA REMAINS IN THE WARM SECTOR WITH
RATHER WARM OVERNIGHT TEMPS AND SWEATY DEW POINTS.

&&

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 250 AM CDT MON JUL 13 2015

MAIN CONCERNS TODAY ARE TWOFOLD...SEVERE WEATHER THREAT THIS
MORNING AND AGAIN LATER TODAY...AND EXTREME HEAT THIS AFTERNOON
AND EARLY EVENING.

RECENT TRENDS INDICATE SEVERE RISK FOR THIS MORNING HAS DIMINISHED SOMEWHAT
AS UPPER LEVEL FLOW IS NOT AS SUPPORTIVE FOR THE WESTERN PART OF
THE WI QLCS MOVING TOWARD OUR AREA AS IT IS FOR THE NORTHEASTERN
SEGMENT.

ONCE THE QLCS AND ASSOCIATED CLOUDS EXIT THE AREA...A LINGERING
BOUNDARY WILL HAVE THE POTENTIAL TO SUPPORT REDEVELOPMENT OF
THUNDERSTORMS IN A SHEAR AND CAPE RICH ENVIRONMENT. THUS THE
SEVERE THREAT COULD REDEVELOP THIS AFTERNOON AND EARLY EVENING...
BUT THE MOST SIGNIFICANT SEVERE WEATHER IS MORE LIKELY TO OUR
EAST.

IF THE SEVERE THREAT IS NOT ENOUGH...HIGH TEMPS IN THE 90S TODAY
IN MANY AREAS ALONG WITH DEW POINTS WELL IN THE 70S WILL PUSH HEAT
INDEX VALUES AT OR ABOVE 100 DEGREES THIS AFTERNOON. ONLY CAVEAT
HERE WOULD BE IF COOL OUTFLOW AND LINGERING CLOUDS FROM THE QLCS
HOLD MAX TEMPS DOWN IN THE NORTHEAST/EAST PARTS OF THE CWA. AT
THIS POINT WILL CONTINUE THE ADVISORY AREA-WIDE AS CONFIDENCE IN
THIS SCENARIO IS LOW.

SOMEWHAT COOLER AND DRIER AIR WILL BEGIN PUSHING INTO THE AREA
LATER TONIGHT AND TAKE THE EDGE OF THE HEAT AND HUMIDITY.

.LONG TERM...(TUESDAY THROUGH SUNDAY)
ISSUED AT 250 AM CDT MON JUL 13 2015

ANOTHER FRONT WILL START DROPPING INTO THE AREA ON TUESDAY. THERE
ARE SOME QUESTIONS REGARDING RAIN CHANCES DURING THE MORNING HOURS
BASED ON WHAT HAPPENS WITH THE CONVECTION THAT DEVELOPS MONDAY
NIGHT. RIGHT NOW IT APPEARS THE NORTHEAST THIRD OF THE AREA MAY SEE
SOME LINGERING CONVECTION DURING THE MORNING.

TUESDAY AFTERNOON...AN UPPER LEVEL DISTURBANCE MOVES ACROSS
WISCONSIN AND ILLINOIS. THE PROXIMITY OF THE FRONT MOVING THROUGH
THE AREA SHOULD ALLOW CONVECTION TO DEVELOP ACROSS THE NORTHEAST
HALF OF THE AREA. THE HUMID CONDITIONS WILL CONTINUE ON TUESDAY BUT
TEMPERATURES SHOULD BE CLOSE TO NORMAL.

TUESDAY NIGHT THERE MAY BE SOME LINGERING SHOWERS AND THUNDERSTORMS
MAINLY EAST OF THE MISSISSIPPI RIVER DURING THE EVENING AS THE NEXT
FRONT MOVES INTO MISSOURI AND SOUTHERN ILLINOIS. AFTER MIDNIGHT DRY
CONDITIONS WILL BE SEEN AS WINDS COME OFF LAKE MICHIGAN.

COOLER AND LESS HUMID CONDITIONS WILL BE SEEN ACROSS THE AREA ON
WEDNESDAY WITH EAST TO NORTHEAST OFF LAKE MICHIGAN. TEMPERATURES
WILL BE A LITTLE BELOW NORMAL. HEAT INDEX READING OF 95 TO 100 WILL
BE POSSIBLE ACROSS THE SOUTH THIRD OF THE AREA.

A NEW THUNDERSTORM COMPLEX SHOULD DEVELOP SOMEWHERE IN SOUTHEAST
NEBRASKA/NORTHWEST MISSOURI AREA WEDNESDAY EVENING AND MOVE
GENERALLY EAST NORTHEAST OVERNIGHT. ALTHOUGH NOT CERTAIN...THE
MODELS ARE SUGGESTING A WING OF ELEVATED CONVECTION MAY DEVELOP
WEDNESDAY EVENING ACROSS THE SOUTHWEST THIRD OF THE AREA. IF THE
THUNDERSTORM COMPLEX DEVELOPS WHERE IT IS CURRENTLY SUGGESTED BY THE
MODELS...IT WOULD MOVE INTO THE AREA AFTER MIDNIGHT WITH THE WESTERN
HALF OF THE AREA HAVING THE BETTER CHANCES OF SEEING RAIN.

THURSDAY ON...

THE HIGH PRESSURE THAT WAS OVER THE GREAT LAKES MOVES TO THE EAST
COAST ALLOWING A WARM FRONT TO MOVE THROUGH THE AREA ON THURSDAY AND
FRIDAY. THE POTENTIAL EXISTS FOR AN ORGANIZED THUNDERSTORM COMPLEX
TO MOVE ACROSS THE AREA ON THURSDAY WITH POSSIBLE REDEVELOPMENT OF
ADDITIONAL STORMS THURSDAY NIGHT INTO FRIDAY. AS SUCH THE MODEL
CONSENSUS HAS CHANCE TO LIKELY POPS THURSDAY AND THURSDAY NIGHT WITH
SLIGHT CHANCE POPS ON FRIDAY. TEMPERATURES WILL BECOME INCREASINGLY
WARM AND MORE HUMID ON FRIDAY.

FRIDAY NIGHT THE MODEL CONSENSUS HAS SLIGHT CHANCE POPS FOR THE
AREA. HOWEVER...THERE ARE QUESTIONS REGARDING THE OVERALL POTENTIAL
FOR RAIN CHANCES. ANY TRIGGER IS EXCEEDINGLY WEAK AND THERMAL DATA
SUGGESTS THE POTENTIAL FOR A WARM LAYER ALOFT. SO THE POSSIBILITY
DOES EXIST THAT FRIDAY NIGHT MAY BE DRY.

THE MODEL CONSENSUS HAS VERY WARM AND HUMID CONDITIONS FOR SATURDAY.
A LAYER OF WARM AIR ALOFT IS EXPECTED TO PREVENT ANY CONVECTION FROM
DEVELOPING DURING THE AFTERNOON. HEAT INDEX VALUES ARE PROJECTED TO
BE AROUND 100.

SATURDAY NIGHT INTO SUNDAY THE MODEL CONSENSUS HAS GENERALLY CHANCE
POPS FOR THE AREA. ANOTHER FRONT IS FORECAST TO MOVE THROUGH THE
AREA BUT THERE ARE DISAGREEMENTS ON THE OVERALL TIMING. HUMID
CONDITIONS WILL CONTINUE WITH TEMPERATURES CLOSE TO NORMAL.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z TUESDAY MORNING)
ISSUED AT 634 AM CDT MON JUL 13 2015

OUTFLOW BOUNDARY FROM THE CONVECTIVE COMPLEX OVER NORTHEAST
ILLINOIS WILL MOVE THROUGH KCID/KMLI AREAS BY 1330Z/13. CONVECTION
BEHIND THE BOUNDARY HAS THE BEST CHANCE OF AFFECTING KDBQ WITH
POTENTIAL MVFR CONDITIONS. OTHERWISE EXPECT VFR CONDITIONS THROUGH
00Z/14 WITH TSRA DEVELOPING AGAIN AFT 18Z/13. IF A TSRA AFFECTS A
TAF SITE AFTER 18Z/13 A BRIEF PERIOD OF IFR CONDITIONS MAY BE
SEEN. AFT 00Z/14 VFR CONDITIONS ARE EXPECTED TO CONTINUE.

SEVERE WEATHER...THERE IS A THREAT OF SEVERE THUNDERSTORMS THIS

THREAT IS DAMAGING WINDS...AND ADDITIONALLY THERE IS A RISK OF
TORNADOES THIS AFTERNOON AND EARLY EVENING. THE SEVERE RISK IS
GREATER EAST OF A LINE FROM DUBUQUE TO THE QUAD CITIES TO
BURLINGTON IOWA AND RELATIVELY LOWER TO THE WEST.

EXTREME HEAT...TEMPERATURES IN THE UPPER 80S TO LOWER 90S WITH DEW
POINTS WELL INTO THE 70S WILL PUSH HEAT INDEX VALUES UP TO OR
ABOVE 100 DEGREES THIS AFTERNOON. SINCE THIS IS THE FIRST HEAT
EPISODE OF THE SEASON...WE HAVE HAD LITTLE OPPORTUNITY TO
ACCLIMATE...THUS IMPACTS ARE MORE LIKELY ESPECIALLY FOR
INDIVIDUALS WHO ARE ACTIVE OUTDOORS THIS AFTERNOON.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

THUNDERSTORMS WILL BE POSSIBLE ON TUESDAY MAINLY EAST OF THE
MISSISSIPPI. SEVERE STORMS ARE NOT EXPECTED.

ADDITIONAL ROUNDS OF THUNDERSTORMS ARE POSSIBLE WEDNESDAY NIGHT
