Aviation
Low level jet and weak isentropic lift will develop shra over our
area this morning with best chances of tsra east of the TAF sites as
upper level shortwave trough moves across our area. Have removed vcsh
as probs have decreased slightly. Shortwave trough moves east of our
area later today with lift weakening and decreasing coverage of
shra tsra. Will monitor radar and model trends for possible updates
to mention precip in the tafs after 16z. Ifr MVFR CIGS and patchy
MVFR vsbys will slowly lift toVFR midday into afternoon only to
lower back to MVFR ifr overnight. SE winds 7 to 14 kts will prevail,
except a period of vrbl less than 5 kts early this morning.

short term (today through Saturday)...

upper air analysis last evening showed a negatively tilted trough
extending from utah to south texas. The flow over texas was generally
from the southwest. At the surface, high pressure was centered to the
northeast and winds across our CWA were from the east to southeast.

Dewpoint temperatures were 5-15 degrees higher than 24 hours ago.

During this period the upper trough will be reinforced by another
trough moving down from the northwest. The low level flow will remain
from the southeast and this combination will produce a chance for
showers and thunderstorms over the eastern half of our area. The best
chances will be during the day today and Saturday. With the
southeasterly flow temperatures will increase and be well above
normal.

Long term (Saturday night through Thursday)...

the upper trough will move across the plains Saturday and Sunday. It
will bring a cold front through our CWA Saturday night and Sunday
morning. The front will bring a widespread chance for rain. Behind
the front breezy northerly winds will bring in cooler, drier air. The
upper flow will become northwesterly Monday. Another dry cold front
will move through the region Tuesday keeping temperatures down
through the end of the period.

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.
