short term tonight through Wednesday night ...

forecast area transitions from mild and dry, back to summertime
through the next 36 hours. Low-level flow begins shifting from dry
northwesterly to northeast and eventually southeast tonight through
the day tomorrow. Last of the pesky little waves riding through the
base of the large eastern us upper trough continues to pass this
afternoon with minimal effect. Surface ridge center shifts to the
mid-atlantic coast overnight and offshore tomorrow opening up the
region to increasingly strong moisture return. Tomorrow should still
be relatively precipitation-free as moisture remains shallow and
little upward forcing present other than afternoon heating. For now
i am keeping low pops confined to the southern fringes of the
forecast area. Pops tomorrow night a little uncertain as the medium
range models begin developing a weak upper low over the central gulf
coast. Again, for now, I am leaning toward keeping my pops limited,
generally slight chance and confined to the southwest corner. Low
temperatures continue to moderate back toward seasonal normals as
afternoon temperatures remain close to normal.

long term Thursday through Tuesday ...

active long term still on tap with widespread shower storm
potential daily given the environmental setup. Only a few
adjustments to raise some late week weekend pops given more
certainty. Otherwise did a refresh on general blend of guidance
and does not appear to deviate from fcst prior. Previous
discussion follows...

long term Wednesday night through Monday ...

no big changes in the long term trend for this model run. Still
looking at high pressure off the mid atlantic coast with a rapid
return flow into the southeast states for Wednesday night into
Thursday. Have added slight chance for far west central ga after
06z Thursday... Increasing pops area wide after 12z Thursday.

Models still hinting at a weak short wave moving from the northern
gulf across ga by the end of the week. Otherwise our area remains
in an unstable moist air mass through the period. An upper trough
deepening over the great lakes and into the oh valley over the
weekend may help push a front into tn. So... Likely pops look
reasonable for north ga on Saturday and have stayed with that.

Otherwise... Mainly chance pops area wide through the period.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
