Aviation 12z tafs
vfr skies and light winds will continue through early this evening.

Surface high pressure will gradually shift east late today, allowing
for a slight increase in S or SW winds. No winds over 12 knots are
expected across the area through 04z. A cold front arrives in the
late evening and is currently forecast to move through the TAF sites
between 05z and 07z. Significant wind gusts over 20 knots are not
forecast at this time through 12z, but there may be some gusts
approaching those levels by around 15z Tuesday. No low CIGS are
forecast to accompany the front.

short term (today through Tuesday)...

surface high with light to calm winds and a dry airmass is producing
well below normal temperatures early this morning. An upper level
trough dropping south across the northern plains causes a weak brief
lowering of surface pressures in the southern plains as the surface
high drifts to the southeast today. Temperatures warm to near normal
or slightly above normal today due to light mainly southwesterly
winds. As the upper level trough moves to upper mississippi valley,
it forces a cold front across our area this evening into overnight
with a reinforcing surface high in its wake. No rain is expected with
moisture levels remaining below normal. Temperatures fall several
degrees on Tuesday from today's readings on cold advection. A tight
surface pressure gradient along with some mixing of moderate winds
aloft indicates breezy conditions with some wind gusts to 25 mph or
so Tuesday late morning into mid afternoon.

Long term (Tuesday night through Sunday)...

surface high settles over our area Tuesday night into Wednesday.

Efficient radiational cooling is expected with low temperatures well
below normal. Another upper level trough moves down from canada on
Wednesday into Thursday. The surface high moves off to the southeast
allowing a warmup to ensue by Thursday. However, it will be short
lived as the upper level trough moves across the plains, a strong
cold front moves across our area Thursday night into Friday morning.

The recent ECMWF has sped up the trough passage across our area to
Friday night, while the other models have been consistent with an
early Friday passage. The ECMWF has slightly deeper moisture and
have retained slight chance pops for a few showers for Friday night.

Confidence is increasing that the coldest temperatures of this fall
season are expected Friday through next weekend as ensemble guidance
has narrowed its spread. Temperatures will average 13 to 18 degrees
below normal. Nearly efficient radiational cooling will allow for low
temperatures in the 30s across the much of the hill country. Some of
the typically coldest spots may flirt with freezing around sunrise
Saturday and Sunday.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
