323 AM CDT MON MAR 9 2009

.DISCUSSION...
/318 AM CDT MON MAR 9 2009/
NEXT FEW DAYS WILL CONTINUE TO BE BUSY WEATHERWISE WITH CONCERNS
ABOUT FLASH FLOODING...SEVERE WEATHER AND STRONG GRADIENT WINDS.
WILL BE ISSUING A FLASH FLOOD WATCH FOR NERN MO AND PART OF W
CNTRL IL FOR TONIGHT AND TUESDAY MORNING. MODELS ARE IN GENERALLY
GOOD AGREEMENT THAT TROUGH ALONG THE WEST COAST WILL MOVE ACROSS
THE UPPER MIDWEST ON TUESDAY NIGHT. WHILE GFS IS THE DEEPEST WITH
THIS SHORTWAVE...IT HAS SUPPORT FROM THE CANADIAN GEM AND ITS
TIMING OF THE SURFACE FRONT LINES UP PRETTY WELL WITH THE REST OF
THE MODELS. SO HAVE USED A BLEND OF THE NAM/GFS FOR THIS FORECAST.

HAVE REMOVED POPS FOR THIS MORNING AND SCALED BACK TO CHANCE POPS
TO COVER JUST CNTRL AND NERN MO/W CNTRL IL THIS AFTERNOON WHERE
925-850 MOISTURE CONVERGENCE AND LARGE SCALE ASCENT WILL BE
INCREASING. HAVE INCREASED TO CATEGORICAL POPS AND ADDED MENTION
OF HEAVY RAINFALL OVER NERN MO/W CNTRL IL TONIGHT WHERE SFC-850MB
MOISTURE CONVERGENCE WILL INCREASE DRAMATICALLY ALONG DEVELOPING
LOW LEVEL TROUGH UNDER BROAD LARGE SCALE ASCENT. PWATS WILL REACH
1.25 INCHES OR GREATER WHICH IS OVER TWO STANDARD DEVIATIONS ABOVE
NORMAL. WILL KEEP HEAVY RAINFALL THREAT GOING UNTIL MIDDAY TUESDAY
WHEN PWATS BEGIN TO DROP AS DRIER MID LEVEL AIR MOVES IN.

SPC HAS MOST OF CWA IN SLIGHT RISK THROUGH TUESDAY.  CHANCES FOR
SEVERE WEATHER WILL INCREASE TONIGHT AS INSTABILITY BEGINS.  SPC
SREF MUCAPES WILL EXCEED 500 J/KG WITH DEEP LAYER SHEAR IN THE
50-70KT RANGE...SO THERE IS A RISK OF WIND PRODUCING MCS ALONG THE
WNW-ESE ORIENTED WARM FRONT IN ADDITION TO ISOLATED LOW TOPPED
SUPERCELLS.  SEVERE THREAT CONTINUES UNTIL THE SURFACE FRONT MOVES
THROUGH ON TUESDAY WITH SREF MEDIAN MUCAPES IN THE 500-1000
J/KG...BUT ANY BREAKS IN THE CLOUDS WOULD CAUSE MORE INSTABILITY
THAT CURRENTLY FORECAST. STRENGTH OF MOISTURE CONVERGENCE AND ORIENTATION
OF FRONT TO UPPER LEVEL FLOW SUGGESTS POTENTIAL FOR A LINE ALONG
THE FRONT...BUT VERY STRONG LOW AND DEEP LAYER SHEAR SUGGESTS
THAT THERE WILL BE SOME SUPERCELLS.

SOUTHERLY WINDS WILL BEGIN TO INCREASE BY THIS EVENING AND WILL
CONTINUE THROUGH TUESDAY BEHIND THE FRONT AS PRESSURE GRADIENT
TIGHTENS AROUND DEEPENING SURFACE LOW.  WILL MENTION THESE WINDS IN
THE HAZARDOUS WEATHER OUTLOOK.

LOWERING AND THICKENING OF CLOUD COVER. CONVECTION ANTICIPATED TO
DEVELOP TOMORROW EVENING WITH STRONG WARM ADVECTION...SO HAVE
ADDED CB GROUPS AT ALL TERMINALS. LATER SHIFTS SHOULD BE ABLE TO
PIN DOWN BEST TIME OF CONVECTION AND ADD TEMPO GROUPS.
