AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
251 PM CDT TUE SEP 18 2007

.DISCUSSION...

DAYS 1-2...

THUNDERSTORM CHANCES THIS EVENING AND TOMORROW WILL BE THE MAIN
FORECAST CONCERNS.

12Z UPPER AIR MAPS HAD THE UPPER TROUGH OVER THE ROCKIES, WHILE WV
LOOP SHOWS THIS FEATURE HAS ALREADY ROTATED OFF TO THE NORTHEAST.
THIS HAS HELPED PUSH THE SFC TROUGH FURTHER TO THE EAST, AND THE
TROUGH AXIS/OLD PACIFIC FRONT HAS MOVED THROUGH MOST OF THE
WESTERN CWA. WINDS HAVE ALREADY VEERED AT DDC, AND DEWPOINTS HAVE
BEEN DROPPING AT OUR WESTERN SITES. HOWEVER, RICH LOW LEVEL
MOISTURE REMAINS IN THE EAST WITH SURFACE DEWPOINTS CLOSE TO 70 F
AND 850MB DEWPOINTS IN THE MID TEENS C. MODIFYING THE 12Z SOUNDING
FROM DDC FOR SURFACE CONDITIONS OF 84 OVER 64 GIVES CAPE VALUES OF
AROUND 2000 J/KG. SHORT FUSE COMPOSITE HAS VALUES PRETTY CLOSE TO
THIS, ALTHOUGH WITH THE CLOUD COVER STILL HANGING AROUND IN OUR
EAST WE STILL HAVE A CAP FOR SFC BASED CONVECTION. STILL, LATEST
SATELLITE LOOP SHOWS BREAKS IN THE CLOUDS AND BETTER VERTICAL
DEVELOPMENT OUT IN BARBER AND PRATT COUNTIES. THINK THAT WE SHOULD
START SEEING THUNDERSTORMS GOING UP ALONG THE BOUNDARY IN THE
EASTERN TWO TIERS OF COUNTIES LATER THIS AFTERNOON. THERE SHOULD
BE PLENTY OF INSTABILITY AND WINDS ALOFT ARE FAIRLY DECENT,
ALTHOUGH NOT A LOT OF DIRECTIONAL SHEAR. THUNDERSTORMS THAT DO GO
UP SHOULD BRING SOME HAIL AND POSSIBLY SOME DAMAGING WINDS. THE
CONVECTIVE ACTIVITY SHOULD DIMINISH AFTER SUNSET AS WE LOSE THE
INSTABILITY.

THE TRUE SURGE OF COLD AIR STALLS OUT OVER NORTHERN KS TONIGHT AND
THEN PUSHES BACK NORTH TOMORROW AS THE LEE SFC TROUGH REDEVELOPS
AND STRONG SOUTHERLY FLOW KICKS IN. LOW LEVEL MOISTURE THAT WAS
SHUNTED OFF TO THE EAST TODAY WILL RETURN BY TOMORROW. BOTH THE
GFS AND NAM MODELS SHOW A WEAK LITTLE SHORTWAVE DISTURBANCE MOVING
THROUGH TOMORROW, WHICH COULD HELP FOCUS THUNDERSTORM DEVELOPMENT.
NAM MODEL SOUNDINGS AGAIN HAVE CAPE VALUES OVER 2000 J/KG.
BUMPED UP POPS JUST A TAD AND ADJUSTED THEM A BIT FOR TIMING, BUT
THINK WE SHOULD SEE A DECENT CHANCE FOR SOME WIDELY SCATTERED
STORMS. THE SOUTHWESTERLY FLOW ALOFT AND LEE SFC TROUGH WILL
CONTINUE INTO WEDNESDAY NIGHT AND THURSDAY. NOT A HUGE AMOUNT OF
UPPER LEVEL FOCUS EVIDENT FOR THURSDAY, BUT NOT OUT OF THE
QUESTION SOMETHING ISOLATED COULD BUBBLE, SO INCLUDED SOME VERY
LOW POPS.

AS FOR TEMPERATURES, MADE ONLY MINOR TWEAKS TO WHAT WE HAD GOING.
WITH 850MB TEMPS IN THE UPPER TEENS TO LOW 20S, WE SHOULD BE ABLE
TO GET HIGHS INTO THE 80S TO LOW 90S ON BOTH WEDNESDAY AND
THURSDAY. MOISTURE AND SOUTHERLY WINDS STAYING UP OVERNIGHT WILL
HELP KEEP LOWS MAINLY IN THE 60S.

DAYS 3-7...

H5 PATTERN REVEALS TROUGH IN THE WESTERN CONUS WITH RIDGE ACROSS
EASTERN CONUS 00Z FRI. AS UPPER LOW CONTINUES TO DIG SOUTHWARD INTO
SOUTHERN CA, IT BECOMES CUTOFF FROM THE H3 JET. LOW IS EXPECTED TO
SPIN OFF THE CA COAST UNTIL JET STREAK MOVES SOUTH FROM WESTERN
CANADA INTO WA/OR BY SAT MORNING. THIS WILL TAKE LOW AND BEGIN ITS
TRACK NORTHEAST. GFS/ECMWF/CANADIAN MODELS ALL AGREE WITH LOW
OPENING BY 00Z SUN AND PUSHING NORTHEAST. AT THE SURFACE, MODELS
AGREE WITH LEE TROF DEVELOPING AND REMAINING IN PLACE THROUGH
FRIDAY. BY 00Z SAT, BOTH GFS/ECMWF DEVELOP WEAK SURFACE LOW IN THE
VICINITY OF WESTERN KS. NO REAL IMPRESSIVE SYSTEM TO CAUSE ANY
ISSUES ACROSS THE PLAINS UNTIL 00Z MON. ALTHOUGH DIFFERENCES EXIST
WITH PLACEMENT OF LOW, MODELS AGREE THAT COLD FRONT WILL SWEEP
ACROSS FA SOMETIME LATE WEEKEND/START OF WEEK. TIMING OF SYSTEM WILL
BE HIGHLY DEPENDANT UPON UPPER LOW OVER CA AND ITS MOVEMENT ACROSS
WESTERN CONUS. FOR NOW, SEE NO REAL REASON TO MAKE MAJOR CHANGES TO
ONGOING FORECAST DURING THIS PERIOD. IN TERMS OF TEMPERATURES, NO
REAL CHANGE IN H85 TEMPERATURES EXPECTED UNTIL FRONTAL PASSAGE EARLY
NEXT WEEK. DO NOTE LEE TROUGH IN PLACE ONCE AGAIN. THIS WILL KEEP
TEMPERATURES INTO THE UPPER 80S AND 90S ACROSS FA UNTIL NEXT FRONT
MOVES THROUGH REGION. GIVEN TIMING OF FRONTAL PASSAGE IS IN
QUESTION, WILL MAKE MINOR ADJUSTMENT THERE AS WELL.

.AVIATION...

DISCUSSION FOR 18Z TAFS.

GCK HAS CLEARED AND TROF IS NEAR SITE. CONTINUE TO SEE MVFR DECKS
AT HYS THIS AFTERNOON. VIS SATELLITE TRENDS SHOW THAT THIS SHOULD
COME TO AN END WITHIN THE NEXT COUPLE OF HOURS. GIVEN AMPLE MOISTURE
FROM DDC TO HYS, ANTICIPATED S/WV MOVING ACROSS FA AND DRYLINE
POSITION, EXPECT SOME CU TO BUBBLE BY MID AFTERNOON AT HYS AND DDC.
THUNDERSTORMS WILL DEVELOP ACROSS CENTRAL KANSAS LATER TODAY IN
VICINITY OF DRYLINE. DID NOT INCLUDE VCTS OR TSRA AT SITES JUST YET
AS EXACT LOCATION OF DEVELOPMENT IS IN QUESTION. ONCE THUNDERSTORMS
MOVE EAST, SKIES WILL CLEAR WITH DRYLINE PASSAGE. BY 06Z WED, ENOUGH
MOISTURE WILL ONCE AGAIN MOVE ACROSS SITES, THAT MVFR CEILINGS WILL
DEVELOP AND SURFACE WINDS WILL BE SOUTHEAST. SHOULD ALSO SEE
VISIBILITIES REDUCE. COULD SEE A BRIEF TIME PERIOD OF IFR CONDITIONS
AT SITES AROUND SUNRISE BUT FOR NOW, WILL ONLY REDUCE TO MVFR.
