AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
322 PM CDT THU JUN 9 2011
.SYNOPSIS...
STATIONARY FRONT/OUTFLOW BOUNDARIES HAVE SET UP OVER NRN MO THIS
AFTERNOON. A SUBTLE S/W IN THE BROAD SOUTHWESTERLY 500MB FLOW WAS
SUPPORTING TSRA/SHRA OVER THE CWFA THIS AFTERNOON AND EXTENDING
WEST THROUGH NORTH CENTRAL IA. CLOUDS...PRECIPITATION AND EASTERLY
SURFACE FLOW NORTH OF THE STATIONARY FRONT HAVE KEPT TEMPERATURES
IN THE 60S AND 70S.
&&
.SHORT TERM...TONIGHT AND FRIDAY...
HAVE EXPANDED THE FLASH FLOOD WATCH TO THE ENTIRE CWFA. BELIEVE
NRN MO TSRA DEVELOPING NEAR THE SURFACE BOUNDARY WILL CONTINUE TO
LIFT NORTHEAST INTO THE SRN MOST CWFA LATE THIS AFTERNOON AND
EARLY THIS EVENING. THESE STORMS WILL WEAKEN AS THE MOVE AWAY FROM
THE SURFACE BOUNDARY BUT COULD STILL PRODUCE SOME HEAVY RAIN AND
PRIME THE GROUND FOR TSRA EXPECTED LATER THIS EVENING OVERNIGHT.
FOR THE OVERNIGHT HOURS MODELS SHOW A 500 MB S/W MOVING FROM THE
PLAINS INTO THE MS VALLEY BY LATE TONIGHT PROVIDING SOME BROAD
SCALE LIFT FOR TSRA DEVELOPMENT. THE LLJ WILL STRENGTHEN AHEAD OF
THE S/W THIS EVENING WITH THE BEST LOW LEVEL CONVERGENCE SETTING
UP OVER THE CENTRAL OR NRN CWFA. THIS ALONG WITH HIGH P/WS STILL
IN PLACE SUPPORTS A HEAVY RAIN THREAT. STORMS SHOULD ALSO BE ABLE
TO TAP SOME DECENT ELEVATED CAPE OVERNIGHT SUGGESTING AT LEAST A
LARGE HAIL THREAT. FRIDAY...MODELS CONTINUE TO LIFT THE MAIN UPPER
TROF INTO THE PLAINS AND MS VALLEY AND A SURFACE LOW ALONG THE
FRONT. THE LOW SHOULD MOVE THROUGH THE SRN CWFA DURING THE LATE
MORNING AND AFTERNOON. THE SEVERE THREAT WILL DEPEND ON HOW MUCH
THE ATMOSPHERE CAN RECOVER AFTER THE OVERNIGHT CONVECTION MOVES
OUT. AT THIS TIME IT LOOKS LIKE THE GREATEST THREAT WILL OVER THE
SOUTHERN THIRD WITH WIND AND HAIL BEING THE MAIN THREATS. A TORNADIC
POTENTIAL EXISTING NEAR THE TRACK OF THE SURFACE LOW IF SUFFICIENT
HEATING CAN OCCUR.
.LONG TERM...FRIDAY NIGHT THROUGH THURSDAY...
WILL KEEP POPS IN FOR THE ENTIRE AREA FOR FRIDAY NIGHT AS THE
UPPER AND SURFACE SYSTEM PULL AWAY FROM THE REGION. HIGH PRESSURE
BUILDS INTO THE REGION FOR SATURDAY INTO SATURDAY NIGHT BRINGING DRY
WEATHER AND PLEASANT MID JUNE TEMPERATURES. RETURN FLOW AND THREAT
OF WAA PRECIPITATION STARTS TO EVOLVE SUNDAY BUT MODELS HAVE BEEN
SLOWING THIS DOWN. AS A RESULT HAVE LIMITED POPS SUNDAY TO LOW
CHANCE OVER THE FAR SOUTHWEST.
FOR THE REST OF THE WEEK BROAD MID LEVEL TROFFING SETS UP OVER THE
WESTERN U.S. WITH ACTIVE WSW FLOW BECOMING ESTABLISHED OVER THE
PLAINS AND MISSISSIPPI VALLEY. THIS WILL KEEP CHANCE POPS IN THE
FORECAST FOR EACH DAY. TEMPERATURES THOUGH THE PERIOD SHOULD
REMAIN NEAR TO JUST BELOW NORMAL. ..DLF..
