Severe Thunderstorm Warning 275, NWS Wichita, KS

AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE WICHITA KS
925 PM CST MON NOV 14 2005

.UPDATE...

EVEN WITH A FAIRLY COMPLEX WEATHER SCENARIO SETTING UP, FOUND IT
TOUGH TO MAKE TOO MANY CHANGES TO THE ONGOING FORECAST.

STRONG UPPER WAVE CURRENTLY MAKING ITS WAY THOUGH THE ROCKIES AS WE
SPEAK. THERE HAS BEEN SOME WIDESPREAD RAIN SHOWERS NEAR GLD OVER
THE LAST FEW HOURS IN RESPONSE TO THIS APPROACHING WAVE. AM
EXPECTING THIS ACTIVITY OVER NW KS TO CONTINUE TRACKING SE TONIGHT
AND SHOULD EXPAND. THE 00Z/15 GUIDANCE HAS ACTUALLY INCREASED THE
AMOUNT OF MID LEVEL INSTABILITY LATE TONIGHT AND EARLY TUE MORNING
OVER CENTRAL AND PORTIONS OF SOUTH CENTRAL KS. WHAT USE TO BE MOSTLY
SLANTWISE INSTABILITY HAS NOW BECOME MORE UPRIGHT INSTABILITY. SO
KEEPING WITH THE THOUGHT THAT THERE SHOULD BE SOME ISOLATED BURSTS
OF MODERATE SNOW POTENTIAL. HOWEVER, FEEL THE AREAL COVERAGE OF
ACCUMULATING SNOW WILL BE VERY LIMITED AND THE BIGGER STORY MAYBE
THE BLOWING NATURE OF THE SNOW. THEREFORE FEEL THE WINTER ADVISORY
IS A GOOD CALL AND WILL LEAVE INTACT.

THE LATEST GUIDANCE HAS ACTUALLY DECREASED THE SURFACE WIND FIELDS
QUITE A BIT COMPARED TO THE 18Z RUNS. HAVE SEEN THIS QUITE A BIT
WHERE THE 18Z ETA GOES TO BULLISH WITH WINDS. SO WOULD NOT BE
SURPRISED IF WINDS ARE ACTUALLY A BIT LESS THAN WHAT WE CURRENTLY
HAVE GOING IN THE GRIDS. HOWEVER, TO KEEP WITH SURROUNDING OFFICES
AND SINCE ITLL STILL BE VERY VERY WINDY, WILL KEEP NPWS AS IS.

ACCAS HAS BEEN INCREASING OVER EASTERN OK AS ISENTROPIC LIFT
INCREASES ALONG AND NORTH OF THE WARM FRONT. STILL THINK SOME OF
THIS ACTIVITY SHOULD CLIP SE KS TONIGHT AND AGAIN PREVIOUS FORECAST
HAS THIS HANDLED WELL. LATEST FORECAST SOUNDINGS CONTINUE TO
INDICATE SOME FOG POTENTIAL IN SE KS WITH MOISTURE ADVECTION RELATED
TO SURGING WARM FRONT. THE AMOUNT OF FOG WILL BE DEPENDENT ON THE
COVERAGE OF SHOWERS AND STORMS WHICH MAY HELP TO SCOUR SOME OF THE
FOG OUT. SO FOR NOW WILL LEAVE MENTION OF AREAS IN.

.PREV DISCUSSION... /ISSUED 354 PM CST MON NOV 14 2005/

DISCUSSION...
FORECAST CHALLENGE IS THE TIMING OF A FRONT TONIGHT AND THE
POTENTIAL FOR SNOW TOMORROW MORNING. BULK OF THIS DISCUSSION WILL
CENTER AROUND THE TONIGHT THROUGH TUESDAY NIGHT PERIODS AS THIS IS
THE PRIMARY PERIOD OF CONCERN.

TONIGHT THROUGH TUESDAY NIGHT:
QUITE A TIME TO COME BACK AFTER A LONG TIME OF FROM DOING THE
FORECAST AS ALMOST EVERY ASPECT OF THE GOING FORECAST NEEDED TO BE
CHANGED OR TWEAKED. THIS IS DUE TO FRONT COMING THROUGH FASTER AS
WELL AS WRAP AROUND PRECIPITATION LINGERING AROUND LONGER WHICH
PREVIOUS MODELS RUNS DID NOT INDICATE.

STRONG ISENTROPIC LIFT IN THE 295K TO 300K LAYER WILL DEVELOP
TONIGHT WITH THE BEST LIFT IN SOUTH CENTRAL AND SOUTHEAST KANSAS.
WITH SOME MOISTURE TRANSPORT MOVING INTO THE AREA, SOME ELEVATED
INSTABILITY IS GENERATED. THIS SHOULD RESULT IN A FEW THUNDERSTORMS,
MAINLY IN PORTIONS OF SOUTHEAST KANSAS AFTER MIDNIGHT.

A STRONG SHORTWAVE, CURRENTLY DIGGING INTO THE NORTHERN PLAINS, AND
ASSOCIATED COLD FRONT, WHICH IS CURRENTLY MOVING THROUGH THE
NEBRASKA PANHANDLE, WILL PUSH THROUGH OUR AREA BETWEEN 06Z AND 12Z
TUESDAY. BEHIND THIS FRONT, VERY STRONG WINDS ARE EXPECTED. 40-50 KT
WINDS FROM ABOUT 900MB TO 850MB COMBINED WITH A TIGHTENING PRESSURE
GRADIENT WILL LIKELY RESULT IN SURFACE WINDS OF 30-40 KT WINDS WITH
GUSTS OF 50 KTS POSSIBLE. AS A RESULT, A HIGH WINDS WARNING HAS BEEN
POSTED FOR SOUTH CENTRAL KANSAS WITH A WIND ADVISORY FURTHER EAST.

AS THE LOW DEEPENS OVER NORTHEAST OKLAHOMA AND MOVES TO THE
NORTHEAST INTO MISSOURI, OUR FIRST SHOT OF WINTER WEATHER WILL
OCCUR. FAVORABLE TEMPERATURES ALOFT FOR SNOW COMBINED WITH VERY GOOD
FRONTOGENESIS FROM ABOUT 700MB TO 650MB, A TROWAL STRUCTURE AND
ELEVATED INSTABILITY ALL POINT TO THE POSSIBILITY OF SEEING HEAVY
BANDED SNOW FROM ABOUT 12Z TO 18Z TUESDAY ALONG AND NORTH OF THE
TURNPIKE. THERE ARE SEVERAL NEGATIVE FACTORS WHICH DECREASE MY
CONFIDENCE. FIRST SOIL TEMPERATURES ARE STILL WARM, HIGH WINDS WILL
BLOW AROUND ANY SNOW THAT DOES FALL AND THERE IS SOME DEGREE OF
UNCERTAINTY IN HOW COLD THE SURFACE TEMPERATURES WILL BE DURING THE
TIME WHEN SNOWFALL IS EXPECTED. HAVING SAID ALL THIS, A WINTER
WEATHER ADVISORY FOR PORTIONS OF CENTRAL KANSAS HAS BEEN ISSUED FOR
THE POSSIBILITY OF BLOWING SNOW AND NEAR BLIZZARD CONDITIONS.

WEDNESDAY THROUGH MONDAY
THE SYSTEM WILL BE PROGRESSIVE AND SHOULD BE OUT OF OUR FORECAST
AREA BY THE AFTERNOON HOURS OF TUESDAY LEAVING OUR COLDEST
TEMPERATURES OF THE YEAR IN ITS WAVE WEDNESDAY MORNING. A SERIES OF
UPPER LEVEL DISTURBANCES WILL MOVE INTO THE AREA FOR THIS WEEKEND.
MADE SOME MINOR TWEAKS TO THE EXTENDED FORECAST TO ACCOUNT FOR THIS
BUT CONFIDENCE IS NOT HIGH ENOUGH AT THIS POINT TO MENTION ANY
PRECIPITATION.
