    We will take the drive up Highway 287 from Decatur to Amarillo today (Sun 3rd May) and arrive at the Fabled Big Texan Restaurant. This will give us a Shot at Elevated Storms with Hail and Good Lightning Opportunities Tomorrow and will also take in a Visit to Greensburg for the Team to see how that Town is coping exactly 2 Years to the day of the EF5 Greensburg Tornado, there may even be a Memorial Service There tomorrow.

    After tomorrow we then get into some More good Chances for Tornadic Storms over Oklahoma with my Favourite Set Up namely the Dryline and Warm Front Triple Point Set up.

    DAY 3 CONVECTIVE OUTLOOK

    NWS STORM PREDICTION CENTER NORMAN OK

    0245 AM CDT SUN MAY 03 2009

    VALID 051200Z - 061200Z

    ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS THE SRN PLAINS...

    ...SYNOPSIS...

    MODELS REMAIN CONSISTENT WITH GENERALLY ZONAL FLOW EXTENDING FROM

    THE WRN U.S. TO THE MS VALLEY...BUT DIFFER IN THE TIMING/

    AMPLIFICATION OF AN EMBEDDED TROUGH EXPECTED TO MOVES ACROSS THE

    CENTRAL PLAINS ON TUESDAY. THE 00Z ECMWF IS SLOWER THAN THE 00Z

    NAM/GFS WITH THE TROUGH BECOMING MORE AMPLIFIED INTO THE CENTRAL/

    SRN PLAINS AND OZARKS REGION BY 12Z WEDNESDAY. MEANWHILE...THE

    NAM/GFS INDICATED A BROAD TROUGH PROGRESSING ACROSS THE CENTRAL

    PLAINS TUESDAY AFTERNOON...WITH LITTLE HEIGHT FALLS INTO THE SRN

    PLAINS.

    FARTHER N...THE DAY 2 SHORTWAVE TROUGH OVER THE NRN PLAINS IS

    EXPECTED TO TRACK NEWD ACROSS MN/WI AND DEAMPLIFY AS IT MOVES INTO

    CONFLUENT FLOW REGIME OVER ONTARIO.

    ...SRN PLAINS...

    ELEVATED TSTMS/MCS SHOULD BE ONGOING AT THE START OF DAY 3 ACROSS

    MAINLY OK...WITH SOME OF THIS ACTIVITY PRODUCING ISOLATED SEVERE

    WITHIN WAA REGIME ALONG NOSE OF 40-50 KT SSWLY LLJ. THIS ACTIVITY

    SHOULD SHIFT EWD THROUGH ERN OK TO AR AND WEAKEN IN INTENSITY/

    SEVERE THREAT AS THE LLJ DIMINISHES IN STRENGTH TUESDAY MORNING.

    ALTHOUGH MODELS DIFFER IN THE TIMING/AMPLIFICATION OF THE SHORTWAVE

    TROUGH...50 KT WNWLY MID LEVEL FLOW IS EXPECTED TO EXTEND ACROSS

    KS/OK AND N TX TO AR BY AFTERNOON. SLY LOW LEVEL FLOW ACROSS TX

    WILL ALLOW A WARM FRONT TO MOVE NWD FROM CENTRAL TX TO ALONG THE RED

    RIVER VALLEY BY MID-LATE AFTERNOON. A DRY LINE IS EXPECTED TO MIX

    EWD AND SHOULD EXTEND SWD FROM WRN KS THROUGH THE ERN TX PANHANDLE

    TO THE TX BIG BEND REGION...WITH A TRIPLE POINT LIKELY LOCATED OVER

    WRN N TX. MOISTURE WILL RETURN NWD THROUGH THE WARM SECTOR WITH

    MID-UPPER 60S SURFACE DEWPOINTS REACHING THE RED RIVER VALLEY

    TUESDAY AFTERNOON. STEEP MID LEVEL LAPSE RATES ATOP THE

    MOIST...WARM SECTOR WILL RESULT IN A MODERATELY UNSTABLE AIR MASS.

    TSTMS SHOULD DEVELOP MID-LATE TUESDAY AFTERNOON FROM THE TRIPLE

    POINT SWD ALONG THE DRY LINE IN NRN TX...WITH ADDITIONAL DEVELOPMENT

    POSSIBLE ALONG THE LEFT OVER OUTFLOW BOUNDARY FROM THE MORNING MCS

    OVER OK.../ESPECIALLY WHERE THIS BOUNDARY INTERSECTS THE DRY LINE/.

    MODERATE INSTABILITY AND STRONG EFFECTIVE BULK SHEAR /EXCEEDING 50

    KT/ WILL SUPPORT SUPERCELLS WITH VERY LARGE HAIL...DAMAGING WINDS

    AND A TORNADO THREAT. THE TORNADO THREAT MAY INCREASE SOME ACROSS

    THE SLIGHT RISK AREA EARLY TUESDAY EVENING AS SWLY LLJ STRENGTHENS

    FROM NRN TX INTO SRN/SERN OK. POTENTIAL WILL EXIST FOR ANOTHER MCS

    TO DEVELOP TUESDAY NIGHT ACROSS PARTS OF OK/N TX AND SPREAD EWD INTO

    AR/SRN MO.

    ...CENTRAL PLAINS TO UPPER MS VALLEY...

    SURFACE FRONT...ATTENDANT TO SHORTWAVE TROUGH MOVING ACROSS MN/WI

    TUESDAY...WILL SPREAD EWD INTO THE UPPER MS VALLEY...AND SLOWLY SWD

    ACROSS THE CENTRAL PLAINS. WEAK LOW LEVEL MOISTURE RETURN ALONG AND

    AHEAD OF THIS BOUNDARY WILL PRECLUDE THE DEVELOPMENT OF STRONG

    INSTABILITY. MODELS SUGGEST TSTMS SHOULD DEVELOP ALONG THIS

    BOUNDARY TUESDAY AFTERNOON WITH AN ISOLATED THREAT FOR HAIL/ STRONG

    WIND GUSTS...WITH THE GREATEST POTENTIAL ACROSS IA SWWD TO CENTRAL

    KS WHERE EFFECTIVE BULK SHEAR WILL BE STRONGER

    After that it looks like North West Flow for the remainder of Tour 1 Trip so it could be 9/10 Chase days which is unheard of.

    On our way to Amarillo and one of the team has bravely decided to do the 72oz challenge :o

    Can you guess who it is?

    There is a live web cam for the Big Texan if you want to watch!! As we are on the move we can't search for their website as our internet access is so slow!!!
