PREV DISCUSSION... /Issued 306 AM EST Mon Jan 23 2017/

SHORT TERM /Today through Tuesday/...

Low pressure aloft over the n GA area is forecast to exit
the area to the ENE this morning. This will lead to an overall
diminishing and ending of the current ongoing showers through
the day with a drier airmass moving over the forecast area tonight
and Tuesday. Wrap around shower potential over n Ga is not played
up by the Hi-Res models so pops trend down through the morning.

Associated surface low pressure moves off to the E as well and
this increases the pressure gradient across the area that will
increase strong gusty winds through the morning. The current ongoing
wind advisory will be continued as sustained winds of 20 mph with
higher gusts can be expected for most areas. The winds will diminish
tonight as a surface ridge approaches the area and moves over on Tuesday.
The wind advisory may need to be extended for some areas of n GA
tonight and this will need to be re-evaluated during the day.

Otherwise a much better weather day is in store for Tuesday.

Forecast high temperatures are running 2-6 degrees above normal today
if we are lucky and 5-9 degrees above normal for Tuesday. Forecast
low temperatures are running 5-9 degrees above normal tonight.

Overall confidence is medium.

LONG TERM /Tuesday Night through Sunday/...

Medium range models in relatively good agreement, at least concerning
the large scale pattern, through the extended forecast period. With
this in mind, and considering the limited time available to delve
deeper into the extended period due to ongoing weather concerns, I
have generally loaded a model blend through the extended period and
made minimal tweaks. Mid-week system brings rain back into the
forecast by Wednesday afternoon, with best chances along and ahead of
the frontal boundary sweeping through Wednesday night into Thursday
morning. Models are keeping any wrap-around moisture north of the
forecast area Thursday night and this period is now dry in our
forecast grids as well. The remainder of the period still looks dry
and seasonably cool.
