...OK/AR...
SHORT-WAVE TROUGH OFF THE COAST OF NRN BAJA PENINSULA IS EXPECTED TO
EJECT INLAND THEN ACROSS THE SRN ROCKIES INTO WEST TX BY 13/18Z.
MID LEVEL SPEED MAX ASSOCIATED WITH THIS FEATURE SHOULD TRANSLATE
DOWNSTREAM ACROSS NORTH TX INTO THE ARKLATEX REGION AS THE WAVE
BEGINS TO DAMPEN LATE IN THE PERIOD. NORTH OF THE PRIMARY JET...MID
LEVEL LAPSE RATES SHOULD STEEPEN SIGNIFICANTLY. THIS LARGE SCALE
ADJUSTMENT WILL LIKELY BECOME FAVORABLE FOR AT LEAST SHALLOW MID
LEVEL CONVECTION...PRIMARILY DURING THE 21-03Z TIME FRAME. BOTH THE
GFS/NAM SUGGEST PARCELS LIFTED NEAR 700MB MAY BECOME BUOYANT ENOUGH
FOR LIGHTNING DISCHARGE AS CLOUD TOPS COULD APPROACH 400MB. EVEN SO
TSTM ACTIVITY SHOULD PROVE WEAK AND MOSTLY ISOLATED WITHIN AN
OTHERWISE INCREASING WARM CONVEYOR OF PRECIP.
