    We are probably going to have a change of plan and not head south, as the risk area will be too far south to drive to deep south TX. We are currently thinking of heading SW as this area will position us closer to tomorrow's risk area over SW TX. Though we will sstop for lunch in Stephenville then look at the 1700z update for day 2 from SPC, look at charts then make a decision on where to go.

    Given the SPC 2 day outlook update and 12z model output for tomorrow - we will probably now head south to Fredericksburg - which is NW of San Antonio. Could be some storms south of there later, and gets us positioned to drop south of there for tomorrow's risk over Sern TX.

    Looking very messy to the SW at the moment with the MCS dominating that region.

    Thanks for posting that up NL, actually a nice cumulus field west and southwest of Fredericksburg where we are headed.

    Really crisp blue skies here in Stephenville, compared to the hazy blue skies yesterday, cold front to our south has scoured some moisture away - so we now have 55F instead of 73F Td's of yeaterday. Temp a comfortable 24C instead of mid 30s of yesterday.

    IND

    CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

    VALID 271849Z - 272045Z

    CONVECTION IS BEGINNING TO DEEPEN/INTENSIFY ACROSS PORTIONS OF THE

    MID MS VALLEY...ESPECIALLY FROM SERN MO INTO SRN IL. THIS ACTIVITY

    IS EVOLVING WITHIN A VERY BUOYANT AIRMASS CHARACTERIZED BY STEEP LOW

    LEVEL LAPSE RATES...ON THE ORDER OF 8 C/KM IN THE LOWEST 3KM...AND

    MLCAPE VALUES OF ROUGHLY 2500 J/KG. LATEST VIS IMAGERY AND LONGER

    RADAR LOOPS SUGGEST TWO REMNANT MCS VORT CENTERS ARE LOCATED JUST NW

    OF SGF AND NEAR LIT. WITH BOUNDARY LAYER EXPECTED TO FURTHER

    DESTABILIZE IT APPEARS A RATHER BROAD SWATH OF ENHANCED THUNDERSTORM

    ACTIVITY WILL EVOLVE FROM NERN AR...NEWD INTO PORTIONS OF SRN

    IL/IND...PARTLY DRIVEN BY AFOREMENTIONED UPPER VORT MAXIMA...BUT IN

    LARGE PART BY AFTERNOON HEATING. GIVEN THE WEAK SHEAR ENVIRONMENT

    IT APPEARS DOWNBURSTS OR PERHAPS SOME HAIL MAY ACCOMPANY THE

    STRONGEST ACTIVITY. WILL CONTINUE TO MONITOR THIS REGION FOR

    POSSIBLE WW.

    The cumulus field to the SW of Fredricksberg , currently in Rocksprings has started to gain

    intensity, not severe by any stretch of the imagination but heading in the right direction,

    up to 18,000ft and half inch hail.

    Yes, can see those cells on Barons SW of Junction, still a long way to go down to the I-10, but will intercept those storms if they are still going when we get down there, we've just passed through Hamilton. Cells should move east which will give us an advantage.

    In 30-50 mins or so those cells have grown twice in size to around 38,000ft and traveling

    E/SE at around 6-12 mph, hope they keep intensifying, how far to intercept around 60-80 mile?

    LOOKS LIKE a nice Supercell in front :(

    any rotation on that Tom B)

    edit...that thing is huge

    Nice to hear from you Pat. Danny suggested that you send me the clip where we were nearly hit by the CG co that I can tie it in with my video to get the same strike from different angles.
