Discussion
Upper ridge seeming to be having more of an influence on our
weather today, as there is no convection developing just yet,
despite development earlier in the day over the last couple of
days. Upper trof and cold front over the wrn CONUS continues to be
blocked by the ridge.

Still appears that we will not get much from this trof cold front
in the way of rain, even as the trof pushes up and over the ridge
later in the work week. It does, however, still look like we will
see a cool down to some degree. The lack of rainfall with the cold
front may lessen the longevity of the cooler airmass, as dry soils
and dry air will likely heat back up more quickly. That said, have
trended slightly above the blended guidance for temps in the
extended.

Dry, near-zonal flow will continue to hold through the weekend
before the models diverge significantly just beyond the end of the
pd. 12

for the 25 18z terminal forecast, will be prevailingVFR flight
categories with clouds and ceilings around or above 4 kft into the
late afternoon or early evening with mostly high cirrus coverage
around 25-30 kft thereafter. Have omitted mention of convection
this issuance, but will amend when afternoon heating and
available moisture allow isolated showers and thunderstorms to
develop. The afternoon convection will most likely be over parts
of east and northeast texas into northwest louisiana, southwest
arkansas, and southeast oklahoma affecting ggg tyr txk shv
terminals. MVFR visibilities look to return on Tuesday morning
between 26 10z-26 14z and some ceilings around 2 kft between
26 12z-26 14z. Surface winds will be light and variable to light
east or southeast 5-8 knots through the forecast period. 06

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.
