.LONG TERM (Sunday through Friday)...An inverted mid and upper
level trough was located across the northwest Gulf of Mexico and
is forecast to close off Saturday night through Sunday somewhere
in the vicinity of the Upper Texas Coast. The GFS and ECMWF move
the low southwest over the Mid Texas Coast on Monday. A spoke of
vorticity and pool of higher moisture is shown to wrap around the

increase in coverage of showers and storms across the central and
eastern CWA. Precipitable water values are forecast to increase to
around 2 to 2.25 inches along and east of I-35 Sunday. The GFS
indicates deep easterly flow develop on Monday as the low is

moisture expanding farther western into the CWA. Pockets of
locally heavy rainfall will be possible Sunday and Monday.
The mid and upper level low will weaken and continue west through
