...DISCUSSION...

ERN PACIFIC UPPER LOW OFF THE CA/NRN BAJA COAST IS EXPECTED TO BE
FORCED EWD INTO THE SRN PLAINS THIS WEEKEND. THIS FEATURE WILL
EJECT AT A FAIRLY LOW LATITUDE WITH A MID LEVEL SPEED MAX POSSIBLY
TRANSLATING ENEWD ACROSS NRN MEXICO INTO FAR SOUTH TX AND THE NWRN
GOM. IT/S NOT ENTIRELY CLEAR HOW MUCH MOISTURE/INSTABILITY WILL
OVERSPREAD TX AHEAD OF THIS FEATURE. OTHERWISE DEEP LAYER SHEAR AND
FORCING WOULD SUGGEST AT LEAST A LOW POTENTIAL FOR A FEW ROBUST
THUNDERSTORMS. GIVEN THE THERMODYNAMIC UNCERTAINTIES WILL NOT
INTRODUCE SEVERE PROBS AT THIS TIME.
