UPDATE.

00z Aviation update below.

PREV DISCUSSION. /Issued 325 PM EDT Wed Aug 5 2020/

SHORT TERM /Tonight through Thursday Night/ .

Seeing fairly widespread convection popping up this afternoon, but overall density of coverage remains somewhat sparse, and intensity remains limited for now. Morning sounding showed a bit of a mid- level cap and shallow lapse rates, but strong heating has not had much trouble overcoming those limitations this afternoon. Still likely to see some strong storms and cannot rule out a few isolated damaging wind gusts. Convection expected to wane through the overnight hours but atmosphere would support an isolated shower or brief thunderstorm through most of the overnight period. Looks like a repeat of this pattern tomorrow as the region remains under weak southwesterly upper flow pattern with ample moisture and moderate instability by midday with good surface heating.

LONG TERM /Friday through Wednesday/.

Fairly typical summertime pattern for the extended portion of the forecast.

An old frontal boundary across south-central/south GA will remain nearly stationary through the weekend. This boundary may begin pushing northward early next week, before dissipating. Near normal temps/humidity for this time of year will lead to the afternoon/evening development of showers and thunderstorms. The old frontal boundary may provide for some focus, providing for slightly higher pops in it's vicinity.

AVIATION. 00Z Update . Mainly VFR conditions thru period. Most convection has diminished though remnant outflow boundaries will keep an isolated chance going into this evening and overnight but chance too low to include mention for now. Some possible lower cigs making into eastern sites for the early morning but keeping SCT 1200-1500 ft with FEW at other sites (KAHN could get close to IFR but will maintain FEW005 and monitor trends overnight). Some MVFR vsbys possible as well mainly for sites other than near KATL. Thursday has similar trend to cu field 4-6 kft and SHRA/TSRA chances from 18-24z and possibly linger a bit later. Winds starting out mostly VRB given outflows and going light VRB overnight (keeping east side for KATL), then back SW 5-6 kts for Thursday afternoon near KATL before flipping again to east side for evening.

//ATL Confidence . 00Z Update . Medium on early morning lower cig potential. High on all else.

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.
