short term today through Friday ...

shear axis weak boundary that has been plaguing the the cwfa for the
last few days will finally shift northward today. Meanwhile, high
pressure aloft and at the surface will try and get a foothold in the
se portion of the cwfa.

With the shear axis weak boundary shifting northward today, the
focus for any precip will also be shifting northward. Even though
the airmass will remain very moist and tropical, precip should
mostly remain unorganized for most of the outlook area. Since the
boundary will flirt with the ga tn border, extreme northern ga
should have the highest amounts of rainfall for the short term
period. Currently, widespread 1" to 2" is possible in this area, but
some locally higher amounts are possible through Friday. For now,
these values shouldn't cause any widespread flooding issues, but
some localized flooding is possible. Will hold off issuing a flood
watch for now. The axis should remain mostly north of the cwfa again
on Friday, so the highest chances will remain in that area.

Hi temps today and Friday will creep up a few degrees, but still
average a few degrees below normal. Even a few peeks of sunshine are
possible south of i-20 today. A bit more sunshine is possible on
Friday.

long term Friday night through Wednesday ...

first half of the extended forecast period remains rather damp as we
deal with the approach, passage and remains of cindy. Still looking
at Friday night as the main severe weather threat as the low mid-
level shear associated with the remnants of cindy sweep through the
region. Instability appears to be moderate at best, but sufficient
to support the marginal to slight risk of severe wind gusts with an
isolated tornado threat. General area of interest still looks to be
roughly along north of the i-85 corridor. Flood threat will be highly
dependent on how much rainfall we get in the next 36 hours leading
up to the passage of the low. Frontal boundary gets stretched out
across the forecast area Saturday with ample moisture remaining. Main
focus for precipitation shifts into central georgia at that time and
slowly diminishes from north to south through Monday Tuesday.

End of the extended forecast period is looking dry and quite pleasant
for the middle of summer. Northwest upper flow and surface high
pressure building over the eastern u.S. Ushers in a dry airmass and
temperatures at or below seasonal normals.

12z update...

bkn ifr CIGS should continue for the next several hours, along
with the on off light rain showers. Do expect CIGS to gradually
lift through the morning, and eventually settle around 035. Winds
may flirt with due south later this afternoon, but overall, the
direction should remain on the east side. Models are hinting at
ifr CIGS again overnight... But kept at low MVFR for now.

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.
