FORECAST CONCERNS CONTINUE TO BE TIMING OF COLD FRONT ACRS THE CWFA
TNT INTO WEDNESDAY...AND ASSOCIATED PRECIP CHANCES.

17Z SFC ANALYSIS INDICATING LOW PRESSURE NEAR IOWA CITY WITH COLD
FRONT EXTENDING SW THRU EAST CNTL IA. MODELS DIFFER A BIT ON
POSITION OF SFC WAVE WITH ETA PUSHING FEATURE TO SW WISCONSIN WHICH
SEEMS A BIT TOO FAR NORTH. AVN AND NGM TAKING LOW ON A MORE EASTERLY
TRAJECTORY...WHILE THE ETA-KF TAKES WAVE TO NEAR RFD BY 00Z WHICH
LOOKS MORE REASONABLE WITH THE EXTENT OF THE CONVECTIVELY MODIFIED AIR
MASS ACRS THE REGION. OTHER THAN SOME MESOSCALE DIFFERENCES NOTED ABOVE
IT APPEARS THE ETA INITIALIZED THE BEST THIS MORNING AND HAS BEEN DOING
A BETTER OVER ALL JOB WITH THE CONVECTION THE PAST 24 HOURS...SO WL SIDE
WITH THAT MODEL THIS FCST PD.

SHORTWAVE ENERGY NOTED ON WATER VAPOR LOOP ACRS THE DAKOTAS INTO ERN
WY FCST TO PUSH EASTWARD THIS EVENING AND GIVE OUR FRONT TO THE WEST
A DECENT PUSH. AS A RESULT...SHOWERS AND THUNDERSTORMS WILL BE LIKELY
AHEAD OF BNDRY TNT ACRS ALL BUT OUR FAR SERN GROUPS. ETA AND ETA-KF
INDICATING A SECONDARY WAVE DVLPG ON THE SRN END OF THE FRONT AS SHORTWV
ENERGY EJECTS OUT OF THE SRN PLAINS ON THU. THIS WL ENHANCE PRECIP CHANCES
ACRS THE SERN HALF OF THE CWFA WITH CHANCE POPS ACRS THE NORTH. BOTH NRN AND
SRN STREAM SHORTWAVES FCST TO BE PUSHING TO OUR EAST BY LT WED NIGHT THU
POPS WILL BE LOWERING FROM NW TO SE...WITH ALL BUT THE FAR SE OUT OF THE
PRECIP BY THU MRNG. THEN HIGH PRESSURE WL BUILD IN FOR THE END OF THE WEEK
AND THE FIRST PART OF OUR WEEKEND WITH MODEL DIFFERENCES REALLY STARTING
TO REAR THEIR UGLY HEADS AGAIN FOR THE SECOND HALF OF THE WEEKEND AND INTO
EARLY NEXT WEEK.

THE AVNX AND MRF SUGGESTING SRN STREAM SHORTWAVE ENERGY TO ROTATE ACRS THE
SRN PLAINS OVER THE WEEKEND WITH A MUCH STRONGER UPPER LVL SYSTEM ACRS THE
ROCKIES. SIG DIFFERENCES EVEN SHOWING UP BETWEEN THIS MORNINGS MRF AND THE
LATEST AVN MODEL IN JUST HOW THE NRN STREAM SYSTEM WILL AFFECT THE UPPER
LOW ACRS THE SOUTH. MODELS ARE NOT DOING VERY WELL WITH THIS WEEKEND PATTERN
SO RATHER THAN MAKE ANY SIG CHANGES TO GOING FCST...WL LEAVE CURRENT EFP
WORDING AS IS.

...PRELIMINARY CCF FOR COORDINATION PURPOSES...
