.PREV DISCUSSION... /Issued 322 PM EDT Tue Oct 20 2020/

SHORT TERM /Tonight through Wednesday Night/...
No major forecast concerns. Isolated light showers over far SE
counties now not expected to measure unless something changes.
Some more substantial showers further SE could make it but will
dissipate after sunset either way. More coverage of SHRA and some
isold TSRA Wed afternoon but again mainly over middle and east
GA. Convection Wed should not be strong or severe but something
to watch. Guidance PoPs a tad lower than this time yesterday which
can`t argue against based on model RH and height fields. Temps
still above average for the foreseeable further.

SNELSON

LONG TERM /Thursday through Tuesday/...
At the start of the forecast period, a slightly more unsettled
pattern will come into play with isolated to scattered PoPs on the
increase. At the surface, high pressure will wedge into the area
from the northeast Thursday into Friday. PoPs will be on the return
as deeper moisture increases and maximized on Friday as a midlevel
disturbance traverses the area.

Meanwhile, a cold front to the northwest will not make progress into
the area and instead stalls over the Tennessee Valley over the
weekend. Scattered convection can still be expected Saturday as deep
moisture remains in place. PoPs Sunday look more isolated with
increased upper ridging. Upper flow turns southwest Sunday into
Monday ahead of the next front, beyond which time model
discrepancies increase substantially. While the ECMWF has favored a
strong cold frontal passage by midweek, the latest GFS holds any
front to the west through that time.

With no cold front in the offing through at least early next week,
temperatures will remain 5-10 degrees above normal.
