AVIATION (12Z TAFS)...

CONCERNS FOR AVIATION WITH THE THUNDERSTORM ACTIVITY LATE THIS
MORNING THROUGH THE EVENING. VFR CONDITIONS WITH MODEST WESTERLY
WINDS WILL BE FOUND OUTSIDE OF STORMS...WITH CIGS AT OR ABV 5K
FT. INSIDE STORMS CIGS NEAR 3K FT AT THE LOWEST WITH VSBYS DOWN TO
2 TO 4 SM AND STRONG WIND GUSTS. THUNDERSTORMS SHOULD START TO
DECREASE AND END LATE THIS EVENING...LEAVING LIGHT WNW WINDS AND
SCT OR FEW CLOUDS OVERNIGHT.

PREV DISCUSSION... /ISSUED 401 AM EDT SUN JUN 22 2008/

SHORT TERM...
TODAY THROUGH MONDAY NIGHT

HIGH PLAINS ENVIRONMENT CONTINUES ACROSS THE SOUTHERN GREAT LAKES.
DEEPENING UPPER LOW PRESSURE OVER THE UPPER GREAT LAKES CONTINUES TO
BRING VERY UNSTABLE AIR TO THE REGION AS NUMEROUS MID LEVEL SPEED
MAXIMA TRANSLATE OVER THE NORTHERN ROCKIES AND MERGES WITH THE GREAT
LAKES VORTEX...AMPLIFYING IN THE PROCESS. THE NEXT DISTURBANCE IN A
SERIES OF IMPULSES CAN BE SEEN DIGGING INTO THE UPPER MIDWEST ON
WATER VAPOR IMAGERY. RADAR DATA CONFIRMS STRONG LIFT ASSOCIATED WITH
THIS DISTURBANCE...AS NOTED BY A BROKEN LINE OF HIGH BASED
CONVECTION OVER NORTHERN IA INTO WI. LOCALLY...A FEW ACCAS WERE
PRESENT ASSOCIATED WITH ONE OF THE MANY SMALL SCALE MID LEVEL
DISTURBANCES. ISOLATED THUNDERSTORMS HAVE FINALLY DISSIPATED WITH
LACK OF ANY SIGNIFICANT FORCING IN THE REGION. STALLED SFC TROUGH
WAS LOCATED ACROSS THE REGION EXTENDING FROM UPPER LOWER MICHIGAN TO
SW PORTIONS OF THE CWA. TEMPS ACROSS THE FA WERE GENERALLY IN THE
UPPER 50S LOWER 60S...WITH CALM WINDS AS OF 07Z.

FORECAST MODELS WERE AGAIN IN GOOD AGREEMENT WITH EACH OTHER...ONLY
A FEW SMALL DIFFERENCES NOTED BETWEEN THE GFS AND NAM...MAINLY WITH
REGARD TO MOMENTUM FIELDS. UTILIZED THE NAM/RUC/GFS/SREF FOR
GUIDANCE.

TODAY...AFOREMENTIONED UPPER LEVEL IMPULSE WILL PUSH INTO THE OHIO
VALLEY REGION...FORCING LARGE SCALE ASCENT AND COOLING OVER THE
REGION. MID LEVEL LAPSE RATES WILL TAKE ON HIGH PLAINS VALUES AS H85
TO H5 LAPSE RATES APPROACH NEAR ADIABATIC VALUES AT 8 C/KM. DISMAL
LL MOISTURE IN PLACE WILL BE HIGHLY OFF SET BY AMPLE MID LEVEL
COOLING/STEEP MID LEVEL LAPSE RATES/AND ADDED ASCENT ON THE LEFT
EXIT REGION OF A POTENT 80-90 KNOT UPPER LEVEL JET STREAK. PROGGED
SB CAPE VALUES OF 1100-1600 J/KG WILL BE MORE THAN SUFFICIENT TO
ALLOW FOR INTENSE UPDRAFTS...ESPECIALLY IN THE SW WHERE THE
AFOREMENTIONED PARAMETERS WILL BE BEST COLLOCATED...INCLUDING 0-6
KM BULK SHEAR OF 30 TO 35 KNOTS. HAVE ADDED SEVERE MENTION IN THE
SOUTH DUE TO THESE CONCERNS WITH MENTION OF LARGE HAIL AND
DAMAGING WINDS...ESPECIALLY WITH 1)DECENT CAPE IN THE HAIL GROWTH
ZONE 2)SUBSTANTIALLY DRY AIR ALOFT/INVERTED V SOUNDINGS/LOW WET
BULB ZERO AT APPROX 7KFT AND PROGGED SFC-MID LEVEL THETA-E DIFF OF
GREATER THAN 20K. NOT RULING OUT DAMAGING WINDS OR HAIL IN THE
NORTH...JUST EXPECT BEST COVERAGE OF SEVERE TS TO RESIDE IN THE
SOUTHERN THIRD OF THE FA WHERE BETTER UPPER LEVEL SUPPORT IS
EXPECTED. LINGERING SFC TROUGH ACROSS THE FA LOOKS TO BE THE FOCUS
POINT FOR INITIATION LATE THIS MORNING/EARLY THIS AFTERNOON.
EXPECTING A SITUATION SIMILAR TO YESTERDAY WHERE NUMEROUS TS
DEVELOPED/CONGEALED AND PUSHED E/SE WITH THE MEAN FLOW. WEAK 0-3
KM SHEAR /10-15 KNOTS/ LOOKS TO AGAIN LIMIT DEVELOPMENT OF A SELF
SUSTAINING LINEAR CONVECTIVE SYSTEM. HOWEVER...SHORTLIVED BOWING
SEGMENTS WILL BE POSSIBLE. THINGS WILL WIND DOWN THIS EVENING AS
HEATING IS LOST AND UPPER WAKE SUBSIDENCE LOOKS TO SETTLE INTO THE
FA.

MONDAY...HAVE CONTINUED LOW CHANCE POPS IN THE EAST WHERE CYCLONIC
FLOW AND STEEP LAPSE RATES PER H5 TEMPS AT -18C WILL BE IN
PLACE...SUPPORTING CONVECTION. NO STRONG CONCENTRATED MID LEVEL
IMPULSES ARE PROGGED AT THIS POINT...BUT ONE MAY BE IN THE CARDS
GIVEN THE NATURE OF THIS SYSTEM. THIS WOULD INCREASE CONVECTIVE
CHANCES AND ALLOW BETTER COVERAGE. WILL HOLD ONTO PREVIOUS FORECAST
FOR NOW.

HAVE RAISED TEMPS TODAY PER H8 MIXING...WITH H8 TEMPS SIMILAR TO
YESTERDAY. HAVE LOWERED HIGHS MONDAY...ESPECIALLY IN THE NW WHERE
LONG
FETCH SUBSIDENT FLOW WILL HOLD TEMPS IN THE 60S AT BEH...SOME 15
DEGREES BELOW NORMAL. HAVE ALSO LOWERED MINS SOME MONDAY
NIGHT...WITH CLEAR SKIES/LIGHT WINDS/AND DRY AIR IN PLACE.

LONG TERM (TUESDAY THROUGH SATURDAY)...

STRONG CONSISTENCY IN THE MEDIUM RANGE MODELS CONTINUES...WITH
LITTLE DIFFERENCE IN THE OPERATIONAL EURO AND THE GFS. A COMPARISON
OF THE H500 FIELDS ARE NEARLY IDENTICAL...WITH SOME SLIGHT PLACEMENT
DIFFERENCES WITH SFC FEATURES ON WEDNESDAY AND THURSDAY. WILL USE
AND BLEND OF NAM12 AND THE GFS FOR THE TUESDAY PERIOD...THEN
TRANSITION TOWARDS THE EURO SOLUTION WITH ITS STRONG CONSISTENCY THE
LAST FEW DAYS. HIGH CONFIDENCE IN THE TUES/WED TIMEFRAME WITH ABV
NORMAL CONFIDENCE IN THE THURS-SAT TIMEFRAME.

TUESDAY THROUGH WEDNESDAY...

TUESDAY LOOKS TO BE THE BEST DAY OF THE WEEK FOR THOSE WITH OUTDOOR
PLANS...JUST BRING ALONG SOME SUNSCREEN AS PLENTY OF SUNSHINE AND
DRY CONDITIONS AS SFC RIDGING AND UPPER LVL RIDGING MOVE ACROSS THE
REGION. SHRTWV WILL APPROACH TOWARDS EARLY WEDNESDAY AND WILL
POSSIBLY BRING SOME SHOWERS AND THUNDERSTORMS EARLY MORNING ON INTO
THE REST OF THE DAY. DEPENDING ON THE AMOUNT OF CLOUD COVER
DAMPENING THE HEATING/INSTABILITY...DECENT ENVIRON FOR MULTICELLULAR
STORMS... MAY BE STRONG WITH GUSTY WINDS AND HAIL AS THREATS. EURO
HAS BEEN HINTING THAT THE PRECIP COULD END OVERNIGHT INTO THURSDAY
AS LAPSE RATES COLLAPSE...INSTABILITY IS LACKING...SLIGHT RIDGE
MOVES OVER THE REGION AND A POSSIBLE LACK OF TRIGGER MAY ALL COMBINE
FOR A LULL IN THE PRECIP CHCS. HAVE LOWERED THE POPS FOR THE
OVERNIGHT PERIOD TO 25 TO START THE TREND FOR A DRIER OVERNIGHT
PERIOD INTO THURSDAY.

SLIGHTLY BELOW NORMAL TUESDAY...SEASONAL TEMPS WEDNESDAY.

THURSDAY THROUGH SATURDAY...

FAIRLY PROGRESSIVE FLOW ACROSS THE NORTHERN TIER OF THE CONUS...WITH
SFC HIGH ACROSS THE SOUTHERN APP MTNS AND UPPER LVL RIDGING OVER THE
SE STATES. SFC BOUNDARY WELL TO THE WEST...PLENTY OF MOISTURE
ACROSS THE REGION WITH DEWPTS INTO THE 60S...WILL CONTINUE LOW END
CHC POPS WITH A BETTER CHC IN THE AFTERNOON WITH DIURNAL/PULSE
ACTIVITY MOST LIKELY. BUFKIT SUGGESTS THAT SOME CAPPING MAY BE IN
PLACE AND LIMIT THE ACTIVITY...TREND TO WATCH AS MID LVL WARMING
STARTING TO SHOW A TREND IN THE MODELS AS H850-700 BUMP UP QUICKLY
THURSDAY AFTERNOON.

BOUNDARY STARTS TO SAG SOUTH AND EAST FRIDAY INTO SATURDAY...DECENT
CHCS FOR PRECIP EACH DAY...CHCS SHOULD START TO LESSEN AS YOU GO
LATER INTO THE WEEKEND WITH OVER INTO SUNDAY LOOKING MOSTLY DRY.
SLIGHTLY ABV NORMAL THURSDAY AND A BIT WARMER FOR FRIDAY...THEN JUST
A BIT ABV NORMAL FOR SATURDAY. MODELS AREA STARTING TO HINT A
POSSIBLE BIG TIME WARMUP IN ABOUT 8-10 DAYS...SOME SUPPORT FROM THE
PNA AND EPO INDEXES...MAY WE HIT OUR FIRST MID 90S OF THE
YEAR...WITH HEAT INDICES IN THE 100S? WILL HAVE TO WATCH THE GROUND
MOISTURE AS IT WILL PLAY BIG IN LIMITING ANY SIGNIFICANT HEAT.
