Update
Updated for 00z aviation discussion

Aviation
00z TAF discussion:
vfr conditions are expected for the next 24 hours with no aviation
concerns. Light mainly easterly winds will occur with a gradual
shift to the southeast through the end of the period. 28

Discussion
Tonight and Wednesday: strong high pressure ridging will prevail
over the area through the period. For tonight, strong radiational
cooling and light winds will allow for temperatures to fall into
the low mid 40s across the area. Clear skies will continue over
the region on Wednesday, with high temperatures climbing into he
upper 70s to around 80 for much of the area. 15
Wednesday night through Monday: a warming trend will be underway at
the beginning of the period as mid level ridge builds over the lower
mississippi river valley in response to a digging trough over the
southwest us. At the surface, east-northeasterly flow around high
pressure, anchored along the east coast, will keep gulf moisture cut
off with dewpoints remaining in the 50s through Friday. With the
bulding ridge and dry air in place, efficient warming will occur
both Thursday and Friday afternoons. Will likely bump up MAX temps a
few degrees those days.

As deep layered ridge moves to the east by Saturday, warm advection
ahead of weak trough over tx will lead to increasing convective
chances over western portions by afternoon. While lapse rates around
6-7c km and vertical totals in the mid 20s are not overly
impressive, 25-30 knots of deep layered shear may allow for a few
strong storms through Sunday.

A more potent mid level wave will approach by Monday. Better lapse
rates associated with the cold core will continue to provide some
strong storm potential. 26

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.
