.DISCUSSION...
308 PM CDT

PERIOD OF TRANQUIL WEATHER AS NO SIGNIFICANT SYSTEMS TO AFFECT THE
REGION OVER THE NEXT SEVERAL DAYS.

STRONG UPPER LEVEL LOW HAS CONTINUED TO SLOWLY LIFT NORTH-
NORTHEAST ACROSS QUEBEC TODAY WHILE HEIGHTS RISE OVER THE UPPER
MIDWEST...WESTERN GREAT LAKES AND MID MS VALLEY AS A RATHER BROAD
UPPER RIDGE PROGRESSES EASTWARD FROM OVER SASKATCHEWAN AND EASTERN
MT AND WY TO WESTERN MANITOBA AND THE DAKOTAS AS THE LEADING WAVE
MOVES OVER THE AK PANHANDLE AND THE B.C. COAST AHEAD OF THE MAIN
UPPER TROUGH AXIS NEAR 150W.

VERY MILD AIR HAS ALREADY SPREAD WILL EAST OVER THE PLAINS WITH
THE 12Z RAOBS FROM THIS MORNING SHOWING 850MB TEMPERATURES OF
+10C OR BETTER OVER THE UPPER AND MID MO VALLEY. THIS WARM AIR TO
CONTINUE TO SPREAD EASTWARD AND OVER THE LOCAL AREA AS THE UPPER
PATTERN CONTINUE TO PROGRESS. MODELS HAVE UPPER RIDGE AXIS TO THE
MS RIVER BY 18Z THU WITH 850 TEMPS AROUND +10C. FEEL THAT THE NGM
MOS PUTTING TOO MUCH WEIGHT ON THESE H8 TEMPS SO GUIDANCE MAX
TEMPS TOO WARM. FORECAST SOUNDINGS SHOW A PRETTY SHALLOW MIXED
LAYER DURING THU AFTERNOON...ONLY UP TO AROUND 925MB. THIS GIVES
MAX TEMPS IN THE LOWER AND MID 60S ACROSS THE FA...MORE IN LINE
WITH THE MAV AND MET AND MEX MOS.

B.C. SHORT WAVE TO MOVE QUICKLY ACROSS CANADA REACHING EASTERN
SHORE OF HUDSON BAY BY 12Z FRI. TRAILING COLD FRONT TO STRETCH
BACK ACROSS THE UPPER GREAT LAKES AND THE UPPER MIDWEST. COMPACT
SHORT WAVE/UPPER LOW CURRENTLY OVER THE ID-WY BORDER IS FORECAST
BY MODELS TO MOVE EAST-SOUTHEAST TO THE KS-MO BORDER BY THIS TIME
AND IS EXPECTED TO SLOW ANY SOUTHWARD PROGRESS OF THIS FRONTAL
BOUNDARY SO TEMPS TO WARM EVEN MORE WITH MID AND UPPER 60S
EXPECTED FRI AFTERNOON.

WHILE SURFACE DEW POINTS CLIMB A BIT ON THE SOUTHWEST SURFACE FLOW
AHEAD OF THE APPROACHING FRONT THE MODELS SHOW A LACK OF ANY
SIGNIFICANT DEEPER MOISTURE AS THE SW FLOW FEEDS DRY AIR
NORTHEASTWARD FROM THE SOUTHERN HIGH PLAINS. THE COLD FRONT IS
PROGGED TO EVENTUALLY SAG SOUTH OF THE WI BORDER ACROSS NORTHERN
IL BY SAT MORNING WITH LITTLE FANFARE GIVEN LACK OF MOISTURE OR
FORCING...AND CORE OF COLD AIR KEPT DISPLACED WELL TO THE NORTH
OF THE AREA. TEMPS WILL DROP OFF TO CLOSER TO SEASONABLE ON SAT
THEN START REBOUNDING AGAIN SUN AS UPPER RIDGE REBUILDS IN
RESPONSE TO NEXT SHORT WAVE TROUGH MOVING TO THE INTERIOR WEST.

MORE SIGNIFICANT COOLING OFF ADVERTISED FOR MID-LATE NEXT WEEK AS
THE MAIN EASTERN PACIFIC/WEST COAST TROUGH MOVES OUT OVER THE
PLAINS. CURRENT MODEL OUTPUT HAS THE ASSOCIATED SURFACE LOW
TRACKING UP ACROSS THE DAKOTAS KEEPING THE LOCAL AREA IN THE WARM
SECTOR WITH A CHANCE OF SHOWERS.

.AVIATION...
1213 PM CDT

1800 UTC TAFS...QUIET PERIOD ON TAP AT THE TAF SITES OVER THE NEXT
24 HOURS AS A RIDGE AXIS MOVES THROUGH THE REGION OVERNIGHT. WINDS
HAVE GONE MORE NORTHERLY AS A WEAK BACKDOOR SFC TROF CAME THROUGH
THIS MORNING. THESE WINDS WILL CONTINUE TO DIMINISH THROUGH THE
DAY AND THIS EVENING AS THE RIDGE AXIS MOVES IN FROM MN/IA WITH
WINDS GOING LIGHT AND VARIABLE OVERNIGHT. THE LOW LEVELS OF THE
ATMOSPHERE WILL BE DRY ENOUGH THAT NO FOG SHOULD FORM OVER NIGHT
EVEN WITH THE CLEAR SKIES...LIGHT WINDS...AND RIDGE OVER HEAD.
WINDS WILL GO BACK AROUND TO THE SOUTH THURSDAY MORNING AND SLOWLY
PICK UP IN INTENSITY THROUGH THE MORNING. SKIES SHOULD MAINLY BE
CLEAR OUTSIDE OF SOME VERY THIN CIRRUS. EXPECT VFR CONDITIONS
THROUGHOUT.

.MARINE...
204 PM CDT

AFTER A BRIEF PERIOD OF WINDS DIMINISHING OVERNIGHT INTO WEDNESDAY
MORNING AS A SFC RIDGE MOVES THROUGH THE LAKE...WINDS WILL BE BACK
ON THE INCREASE OUT OF THE SOUTHWEST AS A POTENT LOW PRESSURE
SYSTEM DEVELOPS UP IN CENTRAL CANADA. WITH THE WARMER
SOUTHWESTERLY WINDS...IT LIKELY WONT BE A SITUATION LIKE THIS
PAST WEEKEND AS IT IS TOUGHER TO PULL DOWN THE STRONGER GUSTS OVER
THE LAKE IN A WARM AIR REGIME. HOWEVER...WITH THE POTENCY OF THIS
SFC LOW AS IT REACHES THE SOUTHERN RIM OF THE HUDSON
BAY...SUSTAINED WINDS WILL APPROACH 30KTS WITH FREQUENT GUSTS UP
IN THE GALE FORCE RANGE. THESE WINDS SHOULD START TO SUBSIDE EARLY
ON FRIDAY AS THE LOW PASSES THROUGH THE BAY AND DROPS A COLD FRONT
INTO THE NORTHERN HALF OF THE LAKE. HIGH PRESSURE THEN BUILDS IN
BEHIND THIS FRONT AND BRINGS A MORE QUIET PERIOD ACROSS THE LAKE.

CURRENT SMALL CRAFT ADVISORY WILL LIKELY BE DROPPED WITH THE
AFTERNOON ISSUANCE AS WINDS HAVE SUBSIDED BELOW ADVISORY CRITERIA
AND WEB CAMS FROM ACROSS THE REGION SHOW THAT THE WAVES HAVE
DROPPED AS A RESULT. WINDS ARE AGAIN EXPECTED TO INCREASE ON
THURSDAY WITH THE SOUTHWESTERLY WINDS SO WILL LIKELY HAVE TO ISSUE
ANOTHER SMALL CRAFT ADVISORY FOR THURSDAY INTO FRIDAY.
