.UPDATED AVIATION DISCUSSION.

.DISCUSSION...
QUIET WX TDA AS WE ARE IN BETWEEN SYS WITH MILD PAC AIR OVR THE
AREA.  FIRST CONCERN IS WITH THE SYS NOW NEAR 46N/132W AND THE
HANDLING BY THE MDLS.  FOR THE MOST PART...HNDLG IS FAIRLY
CONSISTENT WITH THE NAM CLEARLY THE OUTLIER HERE.  NAM CLOSES OFF H5
LOW AND TRACKS IT ACRS IA AND SEEMS TO BE WAY OVER DONE ON THE
MOISTURE INFLOW INTO THE SYS.  AS A RESULT A LARGE BULLSEYE OF PCPN
DEVELOPS IN THE TROWL ALNG THE H7 FNT...HENCE THE FCST OF 26 INCH
SNOWFALL.  FEEL THE ENS-GFS IS LKLY THE BEST WAY TO GO ATTM AND
LEANED THAT WAY.  WENT WITH A SIG INC IN POPS FOR FRI INTO ERY
SAT...BUT KEPT AMTS DOWN.  WILL START OUT AS -RN...BUT SHOULD SEE IT
TRANSITION INTO -SN DURG THE NGT FRI.  DONT EXPECT TO SEE AMOUNTS
ALL THAT GREAT.  NEXT WX SYS FOR SUN NGT INTO TUE IS A BIT COOLER
THAN IT APPEARED YESTERDAY.  FEEL THERE WILL BE A STRONG PUSH OF
WARM AIR...WITH IT LKLY TO BE WARMER THAN THE CUR GFS INDCTS.
SHOULD BE A WET SYS WITH PRETTY GOOD RAFL OVR THE SERN HLF OF IA AND
WUD NOT BE SURPRISED TO SEE A LARGE AREA OF 1+ INCH AMTS.  DECENT
DEFORMATION SNOW IS QUITE LKLY OVR THE NWRN PART OF THE CWA.
OVERALL ACTIVE PATTERN APPEARS TO BE IN ORDER FOR SOME TIME TO COME
WITH THE STRONG PAC JET AND FLOW BCMG FLATTER.  DECENT SUGGESTION OF
PTRN GOING INTO A -PNA PATTERN...WHICH SUPPORTS THIS THINKING.

&&

.AVIATION...13/18Z
A WEAK SHORTWAVE WILL PASS TO THE NORTH OF IOWA TONIGHT BUT A
DISTURBANCE IN THE FLOW WILL LIKELY KICK OFF SOME SHOWERS...MAINLY
OVER SRN MN BUT THESE MAY DRIFT INTO NRN IA...MAINLY AFFECTING KMCW
AND KALO.  SAT PIX SHOWING SOME ACCAS IN SDKTA AND WRN MN WITH THIS
FEATURE WHICH INDICATES SOME INSTABILITY...PROMPTING ME TO PUT A
TEMPO IN FOR SOME VERY LIGHT SHOWERS.  VFR COND XPTD THROUGH 02Z
THEN MVFR/LCL IFR ASSOCIATED WITH SHOWERS.

.DMX WATCHES/WARNINGS/ADVISORIES...NONE.
