SOUTHEAST TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
235 PM CST MON FEB 26 2001

CLOUDY CONDITIONS WILL PERSIST THRU THE WEEK WITH SOUTHWEST FLOW
MOVING OVERHEAD. CHANCE OF PRECIPITATION CONTINUES THRU AT LEAST SAT
AS IMPULSES EMBEDDED IN THE FLOW ALOFT MOVE OVER THE AREA. TOUGH TO
FORECAST TIMING AND PRECIP COVERAGE IN PATTERNS LIKE THIS SO WILL
KEEP CHANCE POPS THRU THE PERIOD. BEST CHANCE LOOKS TO OCCUR IN THE
WED/THU TIMEFRAME WHEN COLD FRONT MOVES THROUGH THE AREA. AS USUAL,
EACH MODEL HAS ITS OWN DIFFERENT SPIN. WILL RIDE WITH ETAS FOR NOW
WHICH DEPICTS FROPA AROUND SUNRISE WED NORTH AND LATE AFTN SOUTH.
TEMPS COULD BE A BUST IF THIS ISNT THE RIGHT ONE, BUT NEED TO
PICK.  OVERRUNNING PRECIP SETS UP THU/FRI. QUESTION IS WHEN THE TROF
OUT WEST DECIDES TO MOVE. ECMWF/MRF SIMILAR IN BRINGING IT ACROSS
THE AREA FRI NT. NOGAPS AND SOME OF THE ENSEMBLES HAVE THE TROF MORE
AMPLIFIED AS MOVES ACROSS LATE SAT. WILL KEEP CLOUDS IN THE FCST
TILL SUNDAY AND INTRODUCE PC CONDITIONS MONDAY.
