Aviation 00z tafs
moisture return continues in advance of approaching cold front that
that will move through the region overnight and early Sunday. Front
expected around 11z aus drt and 12z Sat ssf. MVFR CIGS will develop
all locations starting around 04z east and around 08z for kdrt. Will
likely see brief period in advance of the front with ifr cigs. Cigs
will return to MVFR after frontal passage. Northerly winds will be
10-15 knots behind the front with occasional gusts to 20 knots
through early afternoon. After 20z northerly winds will gradually
decrease to near 10 knots. Expect some streamer showers across the
east in advance of the cold front and post frontal light rain showers
for several hours after the front passes.

short term (tonight through Sunday night)...

a surge of low to mid level clouds signals the approach of the next
weather system for tonight. A cold front will arrive in the pre-dawn
hours over the hill country and should push through our southern
counties by 15z. After 06z tonight showers will begin to form in the
warm sector mainly near and south of Sat through 09z and then begin
forming along the front as it enters our northern counties between
09z and 12z. The troughing pattern over canada and the NRN us
responsible for the front is quite dampened over the central us as a
persistent zonal pattern aloft remains over tx. Thus the front is
expected to produce moderate cooling and will remain shallow enough
to produce overrunning rain chances through the weekend.

There's a slight chance of thunder over parts of the coastal
prairies early Saturday but mainly due to deeper moisture and not
from any dynamic support aloft. The Sunday overrunning pattern should
focus mostly east of highway 281 where the elevated moist layer is
deeper.

Long term (Monday through Saturday)...

the overrunning pattern weakens slightly and pulls east Monday, but
cloud cover and light NE winds keep clouds overhead for continued
cool MAX temps. Another weak polar trough drops through the midwest
and brings another front into tx for early Tuesday. This push of
frontal air should be drier and deeper, so we should see some
partial clearing over the northern counties at least for Tuesday
afternoon. The drying trend is short-lived as a disturbance moving in
the zonal pattern aloft is on track to bring a quick round of rain
chances by Wednesday. Another disturbance passing mainly north of tx
into the central plains Thursday will hold the winds over our area
out of the E NE and maintain mostly cloudy to cloudy skies through
Thursday night. While there isn't much of a frontal push into south
tx with this system for Friday, a subsident regime in its wake could
clear out the low level moisture for Friday afternoon. The rapid fire
of these zonal disturbances are often handled poorly on timing and
locations, so the chance of rain and frontal impacts could be off
mainly in timing. The deterministic 12z GFS ecm runs show poor
agreement for next weekend to reflect this low confidence, the
general trend is that the weather should remain cool but relatively
mild by late november standards for the holiday weekend. Rain chances
look to be low, but that could change with the tracks of the fast
moving zonal perturbations.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
