LONG TERM [Friday through Tuesday]...
The extended period will begin with the last in the series of weak
low pressure waves exiting to our east, with another ridge of high
pressure building in for a fair and cool Friday. The first half of
Saturday looks to be fair and cool at this time as well, but yet
another wave of low pressure may try to return from the Gulf of
Mexico for later on Sat, lasting into Sunday and possibly Monday
as well, with the best chances for rain over the southern portion
of the CWA. Due to the uncertainty of the situation and
significant differences between the 00 UTC GFS (which would call
for fair and dry conditions with a slow moderating trend Sun-Tue),
and the earlier 12 UTC ECMWF (which would likely keep more
unsettled conditions across the area), will await the arrival of
the 00 UTC Euro before making the final call. The new 00 UTC ECMWF
is in, and little has changed. Therefore, will keep PoPs in the
fcst through Sunday Night.
