.AVIATION...
TEMPTED TO BRING PREDOMINANT TSRA TO KSBN INSTEAD OF HEDGE VCTS WITH
LINE OF SHRA SHOWING INCREASED DEVELOPMENT PAST 30 MINUTES FROM VPZ
TO DNV INVOF 55KT LLJ. WILL CONTINUE TO MONITOR LATEST TRENDS AND
KEEP/PULL MENTION AS NECESSARY. LAPS/RUC SOUNDINGS AT KSBN
SUPPORTIVE OF ELEVATED CAPES THIS AM NEAR 300 J/KG WITH PLUME OF
7-7.5 C/KM 7-5H LAPSE RATES. JET FOCUS DECREASES/MIXES WITH TIME
THIS MORNING AND WILL ONLY MENTION SHRA AT KFWA. BIG QUESTION AS TO
WHETHER OR NOT CONVECTION WILL REFIRE ALONG FRONT BEFORE PASSING
KFWA FOR NOW WILL PLAY GREATER ODDS THAT TSRA HAS BETTER CHANCE OF
FIRING SOUTHEAST OF TERMINAL AND FORGO MENTION AND POTENTIAL
OVERFORECAST.

.SHORT TERM...
BUPMED POPS TO HIGH LIKELY AS SHRA BECOMING MUCH MORE NUMEROUS THIS
AM AS LOW LEVEL 50-60KT JET SUPPORT SLIDES EWD INTO CWA AS
PROGRESSIVE MID LEVEL TROF MOVES INTO MISSISSIPPI VALLEY. CORE OF
JET SLIDES TO SE CWA LATER THIS MORNING AND WEAKENS. NAM STILL A BIT
TOO AGRESSIVE WITH MOISTURE POOLING SFC DPS TO NEAR 60 SE CWA THIS
AFTERNOON AHEAD OF COLD FRONT MOVING THROUGH CWA. MID TO POSSIBLY

AND WILL COVER IN HWO. RAISED TEMPS SOUTHEAST IN LINE WITH SFC-925
THERMAL PATTERN AHEAD OF MID/LATE AFTERNOON FROPA. CHANCE FOR
SHOWERS QUICKLY ENDS LATE THIS AFTERNOON WITH DEEPER DRY.

.LONG TERM...
THURSDAY THROUGH TUESDAY...A FAST MOVING UPPER LEVEL SYSTEM WILL
APPROACH THE AREA BY LATE IN THE DAY THURSDAY. THE GFS HAS BEEN
TRENDING THIS SYSTEM A LITTLE STRONGER...BUT STILL QUITE DIFFERENT
FROM THE NAM. THE NAM SOLUTION BRINGS THE SURFACE LOW FARTHER
SOUTH...AND ACROSS THE FORECAST AREA. THE NAM INDICATES A
COMBINATION OF JET DYNAMICS...WARM AIR ADVECTION AND LOW LEVEL
FORCING INDUCING A CONVECTIVE COMPLEX OVER E IA/W IL THEN MOVING
ACROSS NORTHERN INDIANA THURSDAY EVENING. THE GFS KEEPS MOST OF THE
PRECIPITATION WELL TO THE NORTH OVER NORTHERN LOWER MICHIGAN AND
MINIMIZES CONVECTION ALONG THE FRONT. FAVOR...WITH RESERVATIONS...
THE MORE SOUTHERN NAM SOLUTION WHERE THE THERMAL BOUNDARY SHOULD
PROVIDE A FOCUS FOR STORMS TO DEVELOP UPSTREAM AND MOVE INTO THE
FORECAST AREA THURSDAY EVENING. MOISTURE FLUX APPEARS IMPRESSIVE
ALONG THIS BOUNDARY. HOWEVER...SPC CONCERN WITH NAM OVERDOING
MOISTURE RETURN APPEARS VALID AS NAM CAPES THURSDAY EVENING WERE
OVER 3000 J/KG. HAVE NOTICED THIS PATTERN WITH THE NAM IN RECENT
EVENTS...SO PREFER GFS CAPES AROUND 2000 OVER SW AREAS/LOGANSPORT.
KEPT A CHANCE OF STORMS IN FRIDAY AS TRAILING SYSTEM ALONG WITH
RESIDUAL BOUNDARIES COULD FIRE ADDITIONAL CONVECTION. KEPT HIGHS
MAINLY IN THE 70S THURSDAY THROUGH SATURDAY AS 850 MB TEMPS 10-14C
WARMED DRY ADIABATICALLY INDICATE HIGHS IN THE 70S. NEXT SYSTEM
SYSTEM SHOULD ARRIVE SUNDAY...THEN A LARGE SURFACE HIGH SHOULD BUILD
IN FROM THE NORTH. THE ECMWF IS A SLOWER WITH THIS SYSTEM AND
SUGGESTS RAIN MAY LINGER INTO MONDAY. KEPT MONDAY DRY. LOWERED TEMPS
SOME EARLY NEXT WEEK GIVEN TRAJECTORY OF COOL AND DRY AIRMASS. THE
CANADIAN OPERATION RUN ALSO SUPPORTS THE GFS.
