12z tafs
kaus is expected to be around the upper end of lifr and ifr
categories through 14z this morning. After 14z, CIGS over the austin
area airports are forecast to mix lift toVFR conditions through
late tonight. For the san antonio area airports CIGS will be
lingering between ifr and MVFR CIGS through 15z before low clouds
lift toVFR conditions for rest of today and evening. Kdrt is
forecast to remainVFR for the entire forecast period. Winds are
light and variable this morning with a prevailing southerly flow of 5
to 10 knots range forecast this afternoon and evening. The better
chances for rain are forecast across the coastal plains this
afternoon with no impact to the area terminals. Low MVFR CIGS could
happen late tonight across the i-35 sites, however, opted to monitor
closely the situation and wait for new model data to come in to
increase confidence to the late part of the forecast.

short term (today through Monday)...

a mid level shortwave trough axis over western and northern texas is
evident on the latest 6.95um satellite imagery. This trough axis
will drop southward through the area today, bringing some drier and
more stable northerly flow in the mid-levels to our region. We expect
much less coverage of showers and storms this afternoon compared to
Saturday and will only go with a 20-30% chance for areas along and
east of the i-35 corridor. Otherwise, temperatures will warm today
with highs ranging from the mid 90s to near 104. Heat index values
may briefly rise close to advisory levels for areas along and east of
the i-35 corridor this afternoon. For now, we prefer to address the
heat with a special weather statement as confidence is not quite high
enough to warrant a heat advisory.

Upper level ridging continues to build over the region on Monday and
with the low-level thermal ridge strengthening to our west,
temperatures will warm considerably. With continued humid conditions
in the low-levels, afternoon heat index values will likely require a
heat advisory for a good portion of south central texas, except for
possibly a few counties in the hill country.

Long term (Monday night through Saturday)...

mid and upper level ridging will continue over the region as we head
into the middle of the work week. This pattern will keep above normal
temperatures in place along with elevated heat index values across
all of south central texas through Wednesday. We will keep the
forecast dry for all areas on Tuesday, but will opt for a low chance
for showers and storms across portions of the hill country, i-35
corridor and coastal plains on Wednesday as a weak upper disturbance
moves in from the northwest. In addition, the models continue to
hint a weak cold front will approach central texas late Wednesday.

This boundary weakens rather quickly on Thursday and will likely not
bring any relief from the heat.

For the latter half of the week, the oppressive upper ridge will
contract a bit and become better established over the desert
southwest. This should allow temperatures to ease slightly, but we
will continue to have above normal warmth through Friday, with near
normal readings on Saturday. Most areas will also remain dry, but a
few afternoon showers and storms are still possible across the
coastal plains.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
