..NO THUNDERSTORM AREAS FORECAST
..SUMMARY
THUNDERSTORMS ARE NOT EXPECTED ON TUESDAY.
..SYNOPSIS
A SHORTWAVE EMBEDDED WITHIN BROADER-SCALE UPPER TROUGHING WILL MOVE
SOUTHEAST ACROSS THE ROCKIES INTO THE PLAINS ON TUESDAY. AS THIS
OCCURS, LEE CYCLOGENESIS IS EXPECTED OVER THE CENTRAL HIGH PLAINS.
THIS LOW WILL DEVELOP SOUTH/SOUTHEAST INTO TX OVERNIGHT AND ENSUING
LOW-LEVEL SOUTH/SOUTHEASTERLY WINDS WILL TRANSPORT MODEST GULF
MOISTURE NORTHWARD INTO PORTIONS OF SOUTH TX LATE IN THE PERIOD.
FORECAST SOUNDINGS SUGGEST MOISTURE WILL BE RELATIVELY SHALLOW AND
WARMER MIDLEVEL TEMPERATURES WILL LIMIT INSTABILITY. WHILE SOME WARM
ADVECTION SHOWERS COULD OCCUR OVER TX TUESDAY NIGHT INTO EARLY
WEDNESDAY AHEAD OF AN SOUTHEASTWARD ADVANCING COLD FRONT,
THUNDERSTORM POTENTIAL APPEARS LOW.
