Isolated areas of MVFR are possible early and then lift toVFR.
Airmass worked over from storms last night and from subsident zone
north of the activity over the gulf. Texas tech 3km WRF shows the
potential for redevelopment after 20-21z with best chances for
thunderstorms from kcxo to the coast. Texas tech 3km WRF and the
nam end this activity around 03z or shortly thereafter. Guidance
and gfs20 show potential for a return to MVFR starting around 09z

precip off the coast has been contracting and dissipating as the mcv
weakens. Gradient is loosening and we can probably cancel the
coastal flood advisory and gale warnings early if this trend
For the update, we brought grids up to date with latest
obs satellite radar trends. Think we'll mostly see a break in the
action for a while as atmos recovers. But suspect with daytime
heating and residual boundaries we can probably get some sct
showers and tstms to redevelop across inland areas later this
afternoon. Think broadbrushed 30-50% pops look good. 47|

The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
