discussion...

another well earned spring day continues this afternoon after
weeks of dreary, overcast skies. A dry column with ridging
building across the region is yielding a completely cloudless sky
areawide. A nearly identical day setting up for our Friday with
abundant sunshine and light northerly winds.

The surface high will slide off to the east Saturday allowing for
the return of southerly flow and increasing low level moisture.

Scattered to broken cloud cover will develop with a few isolated
showers possible mainly across southeast texas. The increasing
moisture will limit radiational cooling beginning Saturday night
with forecast lows about 10 degrees warmer than tonight and
tomorrow night.

A steadily weakening area of low pressure moving across the
midwest this weekend will swing the next cold front through the
area during the day Monday. This front will be accompanied by
scattered showers and thunderstorms although there is considerable
divergence with regards to how much instability will be available
for convective activity with the GFS resolving much higher values
than the ecmwf. Should the GFS solution prove more accurate, a few
strong to severe storms could be possible.

Behind the front, ridging once again builds in across the region
with very pleasant conditions expected both Tuesday and Wednesday.

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.
