740 pm edt Wed apr 25 2018

Short term tonight through Thursday night
Focus of the short-term forecast period remains the small but
tightly wound system barreling through the region tomorrow. Medium-
range models in fairly good agreement concerning timing and strength
of this system as it approaches and sweeps through. Two main areas
of concern with the system, area of better instability across
central georgia in the warm sector and the mid upper-level cold pool
associated with the closed upper low sweeping across the north. Also
seeing a fairly strong low mid-level jet sweeping across the state.

Biggest concern is when where if any of these elements line up to
enhance the risk for severe thunderstorms. Enough potential for spc
to update the day2 outlook to include a marginal risk across
essentially all of my cwa. As far as timing is concerned, looks like
we should see some showers into the far west and northwest by day
daybreak. Best chances for thunderstorms pushes into the west by mid
to late morning and progresses east across the forecast area into
the afternoon. Some lingering thunder into the evening across the
east and north associated with the lingering steeper lapse rates in
the core of the upper low.

long term Friday through Wednesday ...

only tweaks to the long term based on the latest guidance.

Much of the long term will be rather quiet weather wise.

previous discussion...

trended chances pops to diminish in the north and east with
departing shortwave attendant sfc low at the start of the fcst
period Thursday night. Kept slight thunder mention given some
elevated instability possibly attained with upper forcing.

Another wave quickly on the heels for Friday afternoon into
night, though most guidance has trended drier with this feature
as there lacks moisture transport return ahead. Cannot rule out a
few showers in parts of the north and east ahead of this so have
slight pop mention in the afternoon.

Rest of long term has good consensus to become dominated by a
blocking bermuda ridge so expecting a warmer and drier pattern
shift. Temps should moderate back to above normal by Sunday into
next week with many locations reaching the upper 70s or near 80.

00z update...

ceilings 040-050 should continue to scatter this evening... But
few-sct could linger most of the night. Increasing mid-level
clouds from the northwest after 06z with MVFR ceilings spreading
east and south between 12z and 18z. Isolated to scattered showers
into the western portions of the area... Generally after 12z and
increasing in coverage from through 18z. Isolated to scattered
thunderstorms expected by 18z. Northwest winds diminishing to less
than 8kt after 00z. Winds shift over to northeast and eventually
southeast most areas by 12z.

Atl confidence... 00z update...

medium on timing of MVFR tomorrow, as well as timing of the shift
from NW to NE wind direction. High otherwise.

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.
