Previous
Short term tonight through Thursday night
Current radar loop shows showers and some isolated thunderstorms
across the area this afternoon. Currently there is not as much
activity as yesterday but there is a bit drier airmass over the
state also. We are kind of in between two shortwaves right now
with the second one moving into NW ga just before sunrise
Thursday. There is a decent amount of moisture in the atmosphere
right now but the deepest moisture is east and west of the state.

As this second wave punches into our area early tomorrow morning
we will see increased thunderstorm activity Thursday morning and
afternoon. This coincides well with SPC increasing the slight
risk area to include most of north and central ga. With increased
instability and pws in the 1.5 to 1.8in range looks like the
greatest risks tomorrow will be periods of heavy rain, strong
gusty winds, and hail. Shear values are expected to very weak so
not looking for any tornadic activity. Temps will remain in the
80s to near 90 with low temps in the 60s and 70s.

Long term Friday through Wednesday
Still no major changes needed to the extended portion of the
forecast.

Typical summertime conditions expected for much of the long term
portion of the forecast. Mostly diurnal convection with near to
above normal temps expected. There is one fly in the ointment on
Saturday. The models are still hinting at the potential for an mcs
during the early part of Saturday. Run to run consistency has been
pretty good with timing, but struggling with location.

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.
