What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

331 pm edt Sat jun 23 2018

Short term tonight through Sunday night
The closed upper low drifting over the great lakes will continue to
weaken and push northeast. The broad upper trough that has persisted
over our forecast area will become more zonal overnight. Impulses
moving through the upper flow will continue to produce showers and
thunderstorms through the evening... But show a diminishing trend
overnight. However... With multiple outflow boundaries around there
will be a possibility for a few thunderstorms overnight. The ridge
aloft builds across the area on Sunday... With a diminished chance
for convection.

A few severe thunderstorms moved through far northwest ga and
continued to push east out of the forecast area. The severe
thunderstorm watch has been cancelled. However... There is the
possibility of more strong to severe storms during the afternoon and
evening as convection continues to develop to our west.

For Sunday afternoon... The heat index values across central ga range
from 101 to 104 with isolated values of 105. The next shifts will
take another look for a potential heat advisory.

Long term Monday through Saturday
Mainly only tweaks to the long term based on the latest
guidance.

previous discussion...

still not much change in the over all pattern for the next 6
days, but we may be seeing the beginning of a pattern shift by
day 7. North and central ga will stay in west to northwesterly
upper level flow through Wed thu. This will allow waves and
moisture to continue to move across the area keeping the
southeastern u.S. Convectively active through the period. Still
expecting mainly diurnally driven storms each day as instabilities
peak everyday between 18z-00z across the cwa. The airmass is also
expected to stay fairly moist with pws in the 1.5 to 1.9 inch
range through day 6 7 as well. By Friday it looks like the upper
level flow begins to turn to the NE as a wedge of surface high
pressure build down the eastern seaboard. If this happens we could
see mainly cloudy skies for the Friday Sat with temps dipping a
bit more into the 80s. This is still 7 to 8 days away and do not
have a lot of confidence in this. This is also the first time the
models are showing a possible pattern shift in about a week or
so. As for now will continue with a steady as she GOES approach to
the forecast and keep highs in the lower 90s and chance pops
every afternoon through day 7.

18z update... Should be mostlyVFR this afternoon by but some MVFR
ceilings are developing due to showers and thunderstorms. Some MVFR
stratus possible toward sunrise. Convection should continue to
develop through the evening and diminish later tonight. Winds should
remain on the west side... Occasionally gusty this afternoon.

Expecting overall fewer thunderstorms on Sunday.

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.
