AREA FORECAST DISCUSSION

.DISCUSSION...
224 PM CDT

HAVE BASED NEAR TERM OF FCST ON CURRENT SATLT/MESOSCALE TRENDS.
AFTERNOON VIS IMAGERY SHOWS MID LVL LOW NOW NEAR TWIN CITIES MOVG
ESEWD INTO W CNTRL WI. ASSD TSTM CLUSTER EXPECTED TO STAY N
OF FA THIS EVENING. OF GREATER CONCERN IS CU FIELD ACROSS NRN
IA/SRN MN. EXPECT THIS AREA TO ERUPT WITH DEEP CONVECTION LATE
THIS AFTN AS BOUNDARY TRAILING SWWD FROM LOW OVR MSP INTERACTS
WITH STRONG INSTABILITY AXIS. SBCAPE IN AREA NW OF MCW HAD RISEN
TO 3500 J/KG AS OF 18Z. AS STORMS DVLP ALONG THIS BOUNDARY DURG
THE COURSE OF THIS EVENING...EXPECT LINEAR COMPLEX TO FORM AND
MOVE SEWD. AS A RESULT...WILL MAINTAIN LIKELY POPS AS PER PREVIOUS
FCST...AND MOVE THIS ZONE OF SHOWERS AND STORMS SEWD ACROSS FA
TONIGHT AND TUESDAY. WIND PROFILES LOOK PRETTY WEAK THOUGH...AND
GIVEN LATE NIGHT-MORNING EVENT...CONCUR WITH IDEA THAT MAIN THREAT
WITH THESE STORMS WILL BE LOCALLY HEAVY RAINFALL.

ONLY SIG CHG TO PREVIOUS FCST IS TO ADJUST TIMING OF PRECIP FOR
QUICKER FROPA ON TUESDAY. MODELS HAVE GONE BACK TO FASTER FRONTAL
MOVEMENT ADVERTIZED IN EARLIER RUNS. A COUPLE OF REASONS FOR
CONCURRING WITH THIS SCENARIO INCLUDE INCREASING DOWNWARD
MOMENTUM SUGGESTED BY WATER VAPOR IMAGERY...AND SUBSEQUENT RISES
IN SFC PRESSURE SURE TO BECOME MORE APPARENT AFTER DIURNAL HEATING
SUBSIDES. ALSO...EXPECT OUTFLOW FROM CONVECTIVE DEVELOPMENT
OVERNIGHT TO PUSH/PROPAGATE EFFECTIVE COLD FRONT SWD ACROSS FA
DURING TUESDAY. STILL LOOKS LIKE GREATEST COVERAGE OF SHWRS/TSTMS
ACROSS AREA WILL BE IN PERIOD FROM AROUND MIDNIGHT N AND W...TO
MIDDAY TUESDAY OVR SERN PORTION OF FA WHERE STORMS MAY REFIRE
AFTER DIURNAL DOWN TIME ON TUESDAY.

OTHER CHG IS TO CONTINUE TREND OF INCRSG POPS FOR LATE WED NGT-
THURSDAY AHEAD OF NEXT SHORT WAVE. MODEL TRENDS CONTINUE TO BE
TOWARD A MORE VIGOROUS WAVE WITH AN ORIENTATION MORE CONDUCIVE TO
STRONGER VORTICITY ADVECTION. ASSD WIND MAX LOOKS MORE SUPPORTIVE
OF PERSISTENT...ORGANIZED STORMS. AS A RESULT...HAVE BUMPED UP POPS
INTO CHC MENTION. ONLY COMPLICATING FACTOR WILL BE HOW MUCH LLVL
FORCING/MOISTURE CONVERGENCE WILL BE AVBL AS COLD FRONT MOVES
THROUGH ON THURSDAY. EUROPEAN MODEL FOCUSES DEEPEST MOISTURE INTO
OLD FRONTAL BOUNDARY FCST TO STALL FROM SRN PLAINS TO S OF LWR OH
VLY. ANYWAY...LATER GUIDANCE WILL LIKELY ADJUST TIMING/INTENSITY
OF THIS NEXT SYS SO BELIEVE IT PRUDENT TO JUST GO WITH CHC POPS AND
TO MINIMIZE DURATION OF PRECIP MENTION.

LITTLE CHG DAYS 6-7 AS PERSISTENCE WOULD SUGGEST ANOTHER SYS
PASSING WELL N OF AREA OVER WEEKEND. THEREFORE...WILL KEEP POPS IN
MAINLY SAT NIGHT-SUNDAY AS PER HPC GUIDANCE AND COLLABORATION WITH
ADJACENT FO/S.

.AVIATION...

0000 UTC TAFS...MAIN FORECAST QUESTIONS FOR 00Z TAFS CONTINUE TO
REVOLVE AROUND CHANCES/TIMING OF CONVECTION LATER THIS EVENING AND
AGAIN ON TUESDAY.

AREA OF STRONG/SEVERE THUNDERSTORMS HAVE DEVELOPED ACROSS SOUTHERN
WI LAST FEW HOURS...IN VICINITY OF WEAK LOW PRESSURE REFLECTION
ASSOCIATED WITH MID LEVEL DISTURBANCE AND CONVERGENT BOUNDARIES
NOTED IN AFTERNOON SFC ANALYSIS. LOW LEVEL MOISTURE POOLING FROM
NORTHEAST IA TO SOUTH CENTRAL WI...WHERE SPC/RUC MESOANALYSIS
INDICATES AXIS OF GREATEST INSTABILITY. FARTHER SOUTH...RECENT
ACARS SOUNDINGS FROM KORD INDICATE WEAK CAPPING REMAINS IN
800-850 HPA LAYER...WHICH ALONG WITH LACK OF SIGNIFICANT LOW LEVEL
CONVERGENCE AND MOISTURE POOLING IS PREVENTING DEVELOPMENT THIS
FAR SOUTH/SOUTHEAST AT THIS TIME. WHILE LARGER SCALE FORCING/LOW
LEVEL MOISTURE CONSIDERATIONS SHOULD BECOME SOMEWHAT MORE
FAVORABLE WITH TIME ACROSS NRN IL THIS EVENING...DIURNAL DECREASE
IN LOW LEVEL INSTABILITY WILL LIKELY LIMIT SOUTHEASTWARD EXTENT
AND INTENSITY OF CURRENT IA/WI ACTIVITY. THUS THINKING OF PREVIOUS
FORECAST REMAINS VALID...WITH IDEA OF WEAKENING LINE/AREA OF
CONVECTION EVENTUALLY SAGGING SOUTHEAST LATER THIS EVENING.
CONFIDENCE IN COVERAGE AND TIMING SUPPORT MAINTAINING VCTS FOR NOW
AND WILL MONITOR PROGRESS OF CURRENT ACTIVITY FOR POSSIBLE UPGRADE
TO TEMPO/PREVAILING MENTION IF NEEDED.

COLD FRONT WHICH LAGS CURRENT CONVECTION ACROSS UPPER MIDWEST IS
PROGGED TO SAG ACROSS FORECAST AREA ON TUESDAY. AGAIN SOME
UNCERTAINTY EXISTS WITH COVERAGE/TIMING OF CONVECTION ON TUESDAY
AND THIS WILL BE AT LEAST SOMEWHAT DEPENDANT ON EVOLUTION OF
TONIGHTS STORMS. APPEARS AS THOUGH BEST INSTABILITY WILL
EVENTUALLY MOVE SOUTH OF TERMINALS BY MID/LATE AFTERNOON HOURS SO
FOR NOW HAVE AGAIN MAINTAINED IDEA OF PREVIOUS TAFS WHICH APPEARS
TO HAVE THIS WELL IN HAND.

WINDS FROM SOUTHWEST TO DIMINISH AOB 10 KTS THIS EVENING...THEN
BECOME WEST/NORTHWEST AROUND 10 KNOTS DURING TUESDAY AFTERNOON. OF
COURSE CONVECTIVE OUTFLOW MAY MAKE DIRECTION MORE VARIABLE.

RATZER

&&

.MARINE...
212 PM CDT

A COLD FRONT EXTENDING SOUTH AND SOUTHWEST FROM LOW PRESSURE IN
ONTARIO WILL MOVE ACROSS NORTHERN LAKE MICHIGAN OVERNIGHT AND THE
SOUTHERN PART DURING TUESDAY. SOUTH AND SOUTHWEST WINDS WILL
CONTINUE TO PICK UP TO 10 TO 20 KT DURING THE REST OF THIS
AFTERNOON AND TONIGHT AS THE FRONT APPROACHES. HIGH PRESSURE
GRADUALLY MOVES ACROSS THE MIDWEST TUESDAY NIGHT AND WEDNESDAY.
LOW PRESSURE WILL MOVE UP THE OHIO VALLEY THURSDAY NIGHT AND
FRIDAY.
