Aviation
Vfr conditions will persist through the 22 06z TAF period. Areas
of cirrus CIGS will continue to spread E across the region during
the overnight hours, quickly diminishing thinning from W to e
by prior to daybreak Friday. While some cirrus may linger across
the region during the day, this should thicken up and spread e
into E tx SE ok during the afternoon, and into portions of sw
ar WRN la by late afternoon early evening. Some ac may also affect
portions of NE tx SE ok SW ar by late afternoon early evening as
well. Lt vrb winds will linger tonight through much of Friday, as
sfc ridging remains in place across the region. 15

short term... Tonight
the evening rgb satellite imagery indicates an extensive cirrus
shield quickly spreading E across much of E tx SE ok, entering
portions of SW ar and WRN la, well ahead of a shortwave trough
associated with a well-defined closed low just W of the four
corners region along the nv az ut border. The short term progs
continue to suggest this cirrus shield will shift E across the
remainder of the region overnight, along and ahead of h700-500
ridging over the SRN plains. Satellite imagery suggests that the
cirrus may be a bit dense in spots, thus have beefed up the sky
grids to reflect partly cloudy wording areawide. Meanwhile, the
evening sfc analysis indicates ridging that has begun to expand
swd into the region from ERN ks WRN mo ERN ok, which has resulted
in winds decoupling to near below 5kts as of mid-evening. Given
the dry air mass and light winds in place, temps should continue
to slowly fall overnight, but the presence of the cirrus shield
will help limit the overall temp fall, with min temps several
degrees milder than what was observed this morning. Have made some
minor adjustments to min temps based on the 02z obs, but the
remainder of the forecast is in good shape.

Zone update already out... Grids will be available shortly.

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.
