    Currently In Decatur (Tx) about a 225 mile jaunt down to our Initial Target of San Angelo for tomorrow

    From the SPC

    ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PORTIONS OF SWRN...CNTRL

    AND SCNTRL TX...

    ...SRN PLAINS...

    PERSISTENT UPPER LOW OVER THE SWRN STATES/NRN MEXICO WILL FINALLY

    EJECT EWD ONTO THE SRN PLAINS ON WEDNESDAY. CLUSTERS OF TSTMS WILL

    LIKELY BE ONGOING EARLY IN THE MORNING OVER THE PERMIAN BASIN AND

    LOW-ROLLING PLAINS AHEAD OF THE TROUGH. THIS WILL PROBABLY EXPAND

    NEWD INTO PARTS OF NWRN TX AND OK DURING THE AFTN. MOST OF THIS

    AREA HAS BEEN CONVECTIVELY OVERTURNED SEVERAL TIMES DURING THE PAST

    COUPLE OF DAYS AND ONLY ISOLD HAIL/GUSTY WINDS CAN BE EXPECTED WITH

    THESE STORMS.

    A SLIGHTLY HIGHER PROBABILITY FOR ORGANIZED SVR STORMS WILL EXIST

    FROM THE BIG BEND AND WRN EDWARDS PLATEAU REGION SEWD INTO NRN

    COAHUILA WEDNESDAY AFTN. HERE...THE BOUNDARY LAYER WILL PROBABLY

    RECOVER FROM NOCTURNAL MCS/S AS THE LOW-LEVEL FLOW BECOMES SELY AND

    MAINTAINS FAVORABLE MOISTURE. DIABATIC HEATING WILL CONTRIBUTE TO

    MLCAPES OF 1000-2000 J/KG...ESPECIALLY AS COLDER TEMPERATURES ALOFT

    ASSOCD WITH THE TROUGH SPREAD EWD. THUS...TSTMS WILL LIKELY DEVELOP

    FROM THE SWRN TX MOUNTAINS INTO THE WRN EDWARDS PLATEAU BY

    AFTN...THEN GROW UPSCALE AS THEY HEAD ESEWD DURING THE EVENING.

    UPPER FLOW WILL BE STRONGER THAN PREVIOUS DAYS...ROUGHLY 45-50 KTS

    AT H5 ALONG THE BASE OF THE TROUGH...BOOSTING BULK SHEAR SUFFICIENT

    FOR SUPERCELLS WITH LARGE HAIL. ACTIVITY MAY EVOLVE INTO A LINEAR

    MCS DURING THE EVENING WITH DAMAGING WIND THREATS INCREASING ACROSS

    PORTIONS OF THE CNTRL-ERN EDWARDS PLATEAU. SRN END OF THIS MCS MAY

    MAINTAIN STRONGEST INTENSITY AS IT MOVES OFF OF THE SIERRA MADRE

    OCCIDENTAL AND MOVES TOWARD THE RIO GRANDE VLY. THOUGH INCREASING

    WLY FLOW WOULD ARGUE FOR A POSSIBLE ORGANIZED SVR SYSTEM TO MOVE

    ACROSS SCNTRL TX...ERN EXTENT OF THE SVR SHOULD BE MODULATED BY

    INCREASING CAP AND LWR THETA-E VALUES IN THE LWR TERRAIN.

    There's a nice squall line running through Texas at the moment

    There's also a tornado vortex signature showing on the San Angelo doppler (purple triangle) heading towards Menard.

    The team are currently heading south from Holliday along the squall line. Apparently they have some more fantastic pictures for us to drool over.. :whistling:

    Well, we ended up SW of Witchita Falls today, not as far SW as originally planned, and we waited for some storms to move up from the SSW along a slow moving cold front over Lake Kickapoo (great name) which was a great location to look South and see a line of storms approach over the water. Great cloud stuctures seen with a good shelf cloud developing - expect some good photos soon, cells didn't get supercellular with rotation in the end, so we took some photos then left the storms West of Witchita Falls then headed East to Ardmore, OK, where we are staying the night. Some weakish storms passing North just to the West of us tonight, not particularly electrically active.

    One of the highlights today, apart from some good storm structure photos, was seeing a tarantula walking across a track we had parked on, made us jump at first, then we got fascinated and took photos of it. It was only a small one aswell!

    Tomorrow there's a SLGT risk over Sern TX, but it will be too far (around 400 miles) for us to bother going to, particularly as we need to be back in DFW area on friday for the 5pm flight home. However, still the chance of some scattered t-storms over much of TX and OK tomorrow, so may see something.

    Hey Nick, have a good day and a good flight home, looks like you guys have had a great 07 tour which should bring a warm smile when you reflect back on the last week.

    cheers, Steve James Pete Tom Martin Andy

      Cool with heavy thundery downpours through the weekend & next week

      If you're hoping for some dry and warm weather, then it looks like you're in for a long wait, as the cool and showery conditions will continue through the weekend and much of next week. Some heavy and thundery downpours for many most days. Read the full update here

      Cool Showerfest continues for the next week. Hints of a change beyond that?

      With the jet stream close to the south and low pressure nearby over the next 7 days, expect showers or longer spells of rain over many areas, staying cool too, with temperatures below average. But hints of something drier and more settled arriving next weekend. View the full blog here
