short term today through Tuesday ...

to begin the short term period, the forecast area will be situated
near a weak upper level trough positioned between a broad upper
level ridge in place to the west of the forecast area over the
central plains, and to the east of the area over the western
atlantic. The upper-level troughing is allowing for a northward
advection of the deeper moisture, which will lead to a continued
moistening of the airmass and an overall unsettled pattern through
the period. Pwats of 1.3-1.6 inches across the area this morning
will steadily increase to 1.7-2 inches by Tuesday afternoon. At the
surface, a weak surface low in south georgia will continue to slowly
traverse northward into georgia through the period. This overall
pattern will allow for greater coverage of diurnally driven
convection during the afternoon and evening on Monday and Tuesday,
with primarily high-end chance to low-end likely pops expected
across the area each day.

Widespread severe weather is not anticipated on Monday and Tuesday,
although it is possible that a few storms may become strong to
marginally severe and could produce gusty winds and frequent
lightning. With the increased moisture, there is a possibility that
some of the stronger thunderstorms could produce locally heavy
rainfall, as well. Forecast high temperatures are expected to remain
above climatological normals on Monday. Especially along and north
of the i-85 corridor where highs could range from 5-8 degrees warmer
than average. Heat index values are anticipated to remain below heat
advisory criteria, but will nonetheless reach near or just above 100
across much of the area on Monday, with the exception of the higher
elevations in northeast georgia. Increased sky coverage and
convective coverage will contribute to slightly cooler temperatures
and heat index values less than 100 on Tuesday.

long term Tuesday night through Sunday ...

diurnally driven scattered to numerous showers and thunderstorms
will be the norm in the extended periods of the forecast. The area
will remain situated in the weak upper trough between the ridge
over the plains and western atlantic ridge. Moisture continues to
slowly increase across the area through the end of the week which
will will provide a boost each afternoon for convective development.

By the end of the week, the models are showing a cold front
pushing south out of the great lake state Thursday and into north
ga Friday. The models show this frontal boundary stalling across the
southeastern u.S. And keeping rain chances across the region
through the end of the forecast period. Another weaker wave also
pushes northeast out of the western gulf which will also keep
precip chances going through day 7. As for now, will continue
with scattered to numerous convection each day.

Temperatures, while tempered somewhat by increased convection, will
remain above normal through the week. The increased moisture will
also keep afternoon heat index values from the upper 90s to low
100s.

12z update...

ifr to low-end MVFR ceilings are in place over the southern
portion of the forecast area, including csg mcn and are expected
to build northward over atl ahn by 13z. Conditions will then
improve by 14-15z this morning. Soon after, a CU field at mainly
030-050 will develop and remain through the afternoon into the
evening. Scattered convection is anticipated to develop across
the forecast area during the afternoon hours. Coverage appears
sufficient to support a tempo group for tsra starting at 19-20z.

Winds through the TAF period are expected to be 6 kts or less,
starting from se, becoming E by late morning and shifting back to
se by 02-03z Tuesday. Tomorrow morning, it is possible for MVFR
ceilings and visibility restrictions to develop across csg mcn ahn
after 09z.

Atl confidence... 12z update...

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.
