Vfr conditions are in store for area TAF sites through the forecast
period. Gusty northwest winds will ease shortly with winds expected
to decrease steadily overnight. Other than a few high clouds to our
north, skies will remain clear through the period.

short term (tonight through Wednesday night)...

the surface ridge is over texas and will continue to slowly drift
ese then E over the next 36 hours. The result will be two cold
nights, with morning lows expected in the mid to upper 20s. A freeze
warning is in effect for the entire area tonight. Low dew point will
allow for quick warming once the Sun is up, but it will still be cool
on Wednesday.

Long term (Thursday through Tuesday)...

the surface high and upper level ridge will move east on Thursday,
starting a slow warming trend into the weekend. It will be short-
lived though, as another shallow cold front moves through the region
on Sunday. Besides colder temperatures, southerly flow above the
cold layer will lift moist, gulf air (called isentropic upglide),
which will generate cloudy skies, maintain below normal temperatures,
and bring occasional light rain Sunday night through early Tuesday.

An upper level trough will move through the southern rockies and into
texas by Tuesday. This is where the medium range GFS and ecmwf
forecasts differ significantly, with the GFS having a sharper trough
and much better vertical motion. A blend of these yields high rain
chances Tuesday night and Wednesday, along with mentioning isolated
thunderstorms since the lift provided by the trough and instability
above the near-surface cold dome should allow for isolated
thunderstorms among the widespread showers. Thanksgiving day appears
to be dry with near normal temperatures.

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.
