Clear skies will prevail through the period as high pressure remains
over the area. North flow will continue through the period as a weak
front moves into the region this morning. Speeds should remain less
than 10 knots for the i35 sites but speeds this afternoon will be
around 10-15 knots for drt. Otherwise, no concerns are expected at
the terminals this TAF period.

short term (tonight through Friday night)...

currently left with a post frontal airmass with light NW surface
winds under clear skies. Efficient radiational cooling tonight with
lack of cloud cover will result in overnight temperatures in the 50's
for the hill country and around 60 degrees for the rest of south
central texas. The patchy fog that developed over the hill country
this morning cannot be ruled out again tomorrow morning, but based
on surface rh from forecast soundings in addition to MOS guidance it
is not likely.

Pleasant weather in store for Friday. The region will stay relatively
cool with highs reaching the upper 70's and low 80's. Winds will
begin to veer Friday afternoon as surface high slides east toward the
mississippi valley. Overnight lows in the mid to low 50's.

Long term (Saturday through Thursday)...

ridging over the central CONUS struggles to build as upper level
disturbances make their way across the northern plains over the
weekend. Has no effect on rain chances for our region but results in
zonal flow across the central CONUS into early next week. One of
these disturbances on Saturday tries to bring a front down south but
washes out before getting near the region, looks primarily like a
rain maker for the tx ok border.

As moisture deepens from continuous SE flow off the gulf, cloud cover
returns to the forecast starting Sunday, as well as the chance for
patchy morning fog development. Temperatures on a general warming
trend for the first half of the forecast period look to peak on
Monday in the mid to upper 80's for most locations with the exception
of reaching the low 90's out west.

Next upper level system approaches the region from the west on
Tuesday. Placement of this upper level feature differs slightly with
global models but general agreement on being centered over the four
corners region as a cut off low early Tuesday and kicking off
convection across the central plains northern portion of the state
later in the day. As this low works it's way over the rockies, it is
ingested into mean upper level flow and traverses across the plains
as an open wave. Chances for rain are brought into the forecast for
Tuesday but expect most of the convection to be located just north of
the area where most of the forcing will be. 30 pops are kept in the
forecast through the end of the forecast period with another low
dipping out of the pacific northwest and moving east, aiding in
keeping an overall troughing pattern over the southwestern us.

With a general wetter pattern taking root at the end of the period,
it will be something to watch over the next several days as models
begin to develop a well grounded scenario. Currently there is no
concern about persistent rain chances, just beneficial rains for the
area.

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.
