Surface and upper-level ridge building across the region allow for
mostly clear skies and northwest surface winds around 10 knots
today. Otherwise, winds to become light and variable after 22 00z.

short term... Today through Friday night
surface and upper-level ridge to prevail across the region
through much of the short-term period ending Saturday morning.

By the end of the period, however, southerly flow to return as
surface ridge shifts east and upper-flow becomes southwest. Could
see a few showers developing across east texas by daybreak
Saturday morning.

Under mostly clear skies, temperatures to range from highs in the
lower 70s today with overnight lows in the low to mid 40s. Highs
on Friday to again climb into the low to mid 70s. Otherwise, a
slight warming trend to return on Friday night as low temperatures
fall into the mid to upper 40s. 05
long term... Saturday through Thursday
southwest flow out ahead of this trough will contain weak
perturbations in it to support scattered convection with the greater
coverage likely across our northwest zones by Sat aftn as ECMWF has
consistently modeled. Even the GFS is now likewise with E tx and nw
la QPF signal. There will not be much of any surface feature
associated with this trough on Saturday pm just perhaps a little
heating helping out as the signal diminishes into the evening (ie
sunset).

The consistent ECMWF midterm is now joined once again by GFS with a
weak surface reflection of the filling low and trough in the plains
to mid west. The westerlies will not be enough to clear out the slow
moving remnants. However, as a strong cold front barrels into the
picture the QPF signal will flash wet for our CWA as the remaining
moisture is focused for a good last soaking before sinking slowly
into the i-20 corridor late Sunday and early Monday with no change
on timing really. The cca will be too late for any help Monday pm.

Will need to watch for the possibility of strong to severe
thunderstorms late Sunday night and into Monday ahead of the cold
front as some model prognostications support a moderately unstable
airmass ahead of the front on Monday. The key will be is there
enough deep layer moisture ahead of the boundary. Model dew points
surge back into the lower 60s so surface based activity is very
likely. There is a 15% in our upper red river valley of ok tx and
seems that this could very well be our first slight risk of spring.

The remainder of the extended package looks cooler and drier with no
frost as Tuesday am is too windy and then Wednesday is upper 30 dew
points. 24

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.
