   SEVERE THREAT IS EXPECTED TO SLOWLY INCREASE THIS AFTERNOON AS
   STORMS DEVELOP/INTENSIFY WITH TIME.  EVENTUAL WW ISSUANCE IS
   POSSIBLE.
  
   LATEST VISIBLE SATELLITE AND RADAR LOOPS SHOW CONVECTION SLOWLY
   DEVELOPING ACROSS THE DISCUSSION AREA…BOTH INVOF A SEA BREEZE
   BOUNDARY NEAR THE SERN TX/SRN LA COAST AND ALSO FARTHER N INTO SRN
   MS NEAR THE SYNOPTIC-SCALE FRONT.  THE CONVECTION IS INITIATING
   WITHIN A THERMODYNAMIC ENVIRONMENT FEATURING VERY STEEP LAPSE RATES
   THROUGH A DEEP LAYER…AND A VERY MOIST BOUNDARY LAYER.  THIS
   COMBINED WITH DIURNAL HEATING IS YIELDING MIXED-LAYER CAPE VALUES
   NOW AS HIGH AS 3500 J/KG FROM SERN TX EWD ACROSS SRN LA.
  
   AS HEATING/DESTABILIZATION CONTINUES…AND AS A COMPACT UPPER
   LOW/VORT MAX SHIFTS SEWD OUT OF OK INTO THE ARKLATEX
   REGION…LARGE-SCALE ASCENT SHOULD INCREASE ACROSS THE DISCUSSION
   AREA…SUPPORTING AN INCREASE IN BOTH STORM COVERAGE AND INTENSITY.
   WHILE PROFILER/VWP DATA AND MORNING RAOBS REVEAL MODEST FLOW ALOFT
   — AND THUS SHEAR VALUES GENERALLY UNSUPPORTIVE OF
   SUPERCELLS…DEGREE OF INSTABILITY APPEARS SUFFICIENT TO OVERCOME
   THIS LIMITATION AND YIELD AN INCREASING POTENTIAL FOR LARGE HAIL AND
   LOCALLY DAMAGING WINDS THROUGH THE AFTERNOON.  WHILE WW IS NOT
   IMMINENT…INCREASING POTENTIAL MAY EVENTUALLY WARRANT WATCH
   ISSUANCE.

Don’t worry about any falling sattelite hitting you, Alabama. NASA says the odds are one in 21 trillion! However, if you do beat the odds, NASA urges you not to touch it. Here is the current UARS sattelite location.

Tropical Storm Maria has formed in the Atlantic. Maria looks like she could impact the continental US. Stay connected to AlabamaStormTrackers.com and LiveStormsNow.com for the latest on Tropical Storm Maria and all tropical activity in the Atlantic basin.

The HPC now puts some rather hefty rainfall totals across portions of Alabama into the weekend and next week.  Currently….the NHC continues to hold at Tropical Depression status.  There continues to be a high likelihood that Lee will be born sometime in the next 12 hours.  We will update more as information becomes available…
