Aviation 12z tafs Corrected wording
ceilings have been fluctuating between MVFR andVFR this morning and
expect this trend to continue through 17-19z before daytime heating
results in ceilings lifting toVFR at all terminals. With
southeasterly winds 10-15 knots remaining in place through the taf
period and another strengthening 40 knot low level jet overnight,
expect intermittent MVFR stratus to develop again 02-05z Friday.

Frequent gusts in the 20-25 knot range are again expected from late
morning into the evening as scattering ceilings allow for stronger
winds above the surface to mix down. With the nasa geos-5 biomass
burning fields indicating a swath of denser smoke shifting west
of the interstate 35 terminals towards drt and persisting through
the day, have prevailed haze in the drt TAF with visibility drops
to MVFR (4-5 sm) possible as this smoke lingers through the end of
the TAF period. Otherwise, will be watching the higher terrain of
mexico for any thunderstorms that are able to make a run for drt
but overall coverage is too low to mention in the taf.

short term (today through Friday)...

upper air analysis last evening showed a low over the inter-mountain
west and a high over the southeast. The flow over texas was
southwesterly. At the surface, winds were from the southeast keeping
dewpoint temperatures in the middle 70s over most of our cwa. The
upper pattern will be stagnant during this period with southwesterly
flow remaining in place. Strong southeasterly flow in the low levels
will also continue. Despite the moist boundary layer there will be a
strong cap in place and no lifting mechanism, so we will stay dry
through this period. Most of the area will start off cloudy and then
clear during the afternoon. High temperatures will be a few degrees
above normal today and Friday. There will be a slight chance for
thunderstorms tonight in val verde county as storms will develop over
the higher terrain in mexico and could move across the rio grande,
but this is unlikely. Morning lows will also be above normal with
cloudy skies trapping radiation.

Long term (Friday night through Wednesday)...

the upper high over the southeast will continue to dominate through
the long term period. The upper flow will continue to be from the
southwest. And at the same time, the low level flow will continue to
be southeasterly. High pressure will keep any surface boundaries away
from our cwa. With subsidence keeping the boundary layer capped the
extended period will continue dry. Temperatures will continue above
normal, but will not change significantly from day to day.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
