...UPDATED AVIATION DISCUSSION...

.DISCUSSION...

SHORT TERM (TONIGHT-SUNDAY NIGHT)...

POSITIVELY-TILTED UPPER TROUGH CONTINUES TO DIG INTO THE CENTRAL US
THIS AFTERNOON...WITH WELL-DEFINED SHORTWAVE DIGGING INTO THE TX/OK
PANHANDLES. AHEAD OF THIS FEATURE...SHARP FRONTAL BOUNDARY CONTINUES
ITS SLOW MOVEMENT INTO CENTRAL MISSOURI. WIDESPREAD CONVECTIVE COMPLEX
DEVELOPED EARLIER THIS AFTERNOON ACROSS ERN KS/WRN MO WHERE 850 HPA
CONVERGENCE WAS MAXIMIZED...AND INTERACTIONS WITH BAROCLINIC BOUNDARY
WAS ABLE TO OVERCOME MEAGER ELEVATED INSTABILITY. THIS ACTIVITY WILL
CONTINUE TO PUSH EAST OF THE CWA THIS AFTERNOON AS LOW LEVEL
CONVERGENCE CONTINUES TO SHIFT INTO EASTERN AND SOUTHERN
MISSOURI.

FRONT WILL BEGIN TO ACCELERATE EASTWARD TONIGHT AS SHORTWAVE DIGS
INTO THE SOUTHERN PLAINS AND SECONDARY VORT MAX DROPS INTO THE
EASTERN DAKOTAS. LOW LEVEL POST FRONTAL DOWNGLIDE WILL CAUSE A STEADY
DECREASE IN COVERAGE FROM WEST TO EAST THROUGH THIS EVENING...THOUGH
ELEVATED ISENTROPIC LIFT IN THE 295-305 K LAYER WILL LINGER UNTIL
700 HPA BOUNDARY SWINGS THROUGH AFTER 00Z. ADDITIONAL LIFT EXISTS
OVER NORTHWEST MISSOURI IN ASSOCIATION WITH WEAK DEFORMATION AXIS ACROSS
THIS REGION...WHICH WILL CONTINUE TO PIVOT EASTWARD ACROSS NORTHERN
MISSOURI THIS EVENING. WILL CONTINUE TO CARRY POPS FOR MUCH OF THE
REGION THROUGH THE EVENING UNTIL ELEVATED BOUNDARY PUSHES
THROUGH...THOUGH ANY ADDITIONAL PRECIP SHOULD BE LIGHT IN NATURE.

MODEST COLD AIR ADVECTION HAS ALREADY BROUGHT THE FREEZING LINE INTO
THE FAR NORTHWEST CWA...WHERE THERMAL PROFILES SUPPORT AN IP/SN
MIX...POSSIBLY EVEN MIXED WITH ZR. DEEP MOISTURE ACROSS THIS REGION
IS LESSENING...AND IS FOCUSED MAINLY BELOW 700 HPA WHICH IS BELOW
THE BEST LIFT IN DEFORMATION AXIS. THUS...EXPECT PRECIP ACROSS THIS
AREA TO CONTINUE TO DECREASE IN COVERAGE...WITH LITTLE IF ANY
ACCUMULATIONS OF WINTRY PRECIP. COLD AIR ADVECTION WILL CONTINUE INTO
THE REMAINDER OF THE CWA OVERNIGHT...WHICH WILL FAVOR SN OR IP IN ANY
AREAS WHERE PRECIP LINGERS. WITH BEST LIFT PUSHING WELL TO THE EAST
OF THE REGION...DO NOT EXPECT MUCH IF ANY ACCUMULATION OVERNIGHT.

HIGH PRESSURE WILL BUILD INTO THE NORTHERN AND CENTRAL PLAINS ON
SATURDAY. PREFERRED TO STAY CLOSER TO THE MORE PESSIMISTIC NAM
SOLUTION WITH CLOUD COVER ON SATURDAY GIVEN PLENTY OF LOW LEVEL
MOISTURE BEHIND TODAYS SYSTEM...WHICH WILL BE TRAPPED BELOW A FAIRLY
SIGNIFICANT LOW LEVEL INVERSION. THIS MOISTURE WILL SCOUR OUT FROM
WEST TO EAST THROUGH BY LATE AFTERNOON AS SFC HIGH CONTINUES TO BUILD
IN. LOW LEVEL RIDGING WILL CONTINUE TO STRETCH ACROSS THE CENTRAL AND
NORTHERN PLAINS THROUGH SUNDAY NIGHT...WITH SEASONAL TEMPS AND DRY
CONDITIONS EXPECTED THROUGH THIS TIME.

HAWBLITZEL

MEDIUM RANGE (MONDAY-FRIDAY)...

FOR MONDAY...ZONAL FLOW WILL PREVAIL ACROSS THE CENTRAL CONUS...WITH
OUR ATTENTION DRAWN TO THE UPPER LEVEL LOW THAT WILL MOVE ONSHORE
OVER THE PACIFIC NORTHWEST. THIS UPPER LEVEL LOW WILL DIG FURTHER
SOUTH ACROSS THE ROCKIES MONDAY NIGHT INTO TUESDAY.

THE MAIN DISCREPANCY WITHIN THE MODELS IS IN REGARDS TO THE TRACKING
AND TIMING OF THE SURFACE LOW AS IT SWEEPS ACROSS THE CENTRAL
PLAINS. BOTH THE ECMWF/GEM SHOW THE SYSTEM STARTING TO IMPACT THE
AREA BY TUESDAY MORNING. GFS ON THE OTHER HAND IS A BIT
SLOWER...WITH PRECIPITATION NOT MOVING IN UNTIL LATER TUESDAY
AFTERNOON. GFS/ECMWF KEEP THE REGION PREDOMINANTLY IN THE WARM
SECTOR AS THE SYSTEM PROGRESSES EASTWARD. GEM MODEL THOUGH IS
SHOWING MORE OF A SOUTHERN TRACK WHICH WOULD PUT US NORTH OF THE
WARM FRONT. FORECAST REFLECTS MORE OF A GFS/ECMWF TRACKING...BUT
BEING DAYS 5-6...A LOT CAN STILL CHANGE IN THE MODELS. AS THE
ASSOCIATED COLD FRONT APPROACHES THE REGION TUESDAY EVENING...A
STRONG SOUTHERLY FLOW COMBINED WITH A LOW LEVEL JET OF AROUND 50KT
WILL USHER IN WARM MOIST AIR INTO THE AREA...WHICH WILL AID IN THE
POTENTIAL FOR THUNDERSTORMS. AT THIS TIME...CAN'T RULE OUT THE
POSSIBILITY FOR SOME SEVERE WEATHER WITH THESE THUNDERSTORMS TUESDAY
AFTERNOON AND EVENING. WITH THE ECMWF BEING THE MORE PROGRESSIVE
MODEL COMPARED TO THE GFS...IT SHOWS THE COLD FRONT SWEEPING
EASTWARD OVER THE AREA TUESDAY NIGHT.

ANOTHER FEATURE OF THIS SYSTEM IS THE POTENTIAL FOR SOME WRAP-AROUND
PRECIPITATION AS THE SFC LOW PROGRESSES EAST OF THE REGION. WITH
HIGH PRESSURE SINKING SOUTHWARD INTO THE CENTRAL PLAINS BEHIND THE
PASSAGE OF THIS SYSTEM...COLDER AIR WILL FILTER INTO THE AREA AND
RESULT IN THE CHANCE FOR A RAIN/SNOW MIX ON WEDNESDAY AS THE
REMAINING PRECIPITATION EXITS THE AREA.

FOR THE LATTER HALF OF NEXT WEEK...HIGH PRESSURE WILL REMAIN OVER
THE CENTRAL CONUS WITH DRY CONDITIONS AND NEAR TO SLIGHTLY ABOVE
SEASONAL NORMAL TEMPERATURES EXPECTED.

.AVIATION...

FOR THE 06Z TAFS...LATEST SATELLITE IMAGERY AND OBSERVATION TRENDS
SHOW THE BACK EDGE OF THE HIGH IFR/MVFR CIGS PUSHING THROUGH
SOUTHEASTERN NEBRASKA AND NORTHEASTERN KANSAS. THE RUC CONDENSATION
PRESSURE DEFICIT FORECASTS SEEMS TO MATCH THIS AREA REASONABLY WELL
AND THROUGH COMBINATION OF EXTRAPOLATION AND MODEL OUTPUT THINK
THAT THE TERMINALS WILL ACTUALLY SCATTER OUT MUCH SOONER THAN
PREVIOUSLY THOUGHT. THIS YIELDS VFR CONDITIONS BETWEEN 08Z AND 10Z.
SKIES ARE EXPECTED TO BECOME CLEAR BY THIS AFTERNOON AS STRONG AND
DEEP ISENTROPIC DOWNGLIDE AND DRY SHOULD INHIBIT CLOUDS.
