500mb analysis shows ridging across Mexico that extends into the
northern Gulf. A low pressure system is across southern NV. The low
pressure system will move east and fill through Monday. The ridging
across Mexico and the northern Gulf will build northeastward into
the southeast states. NW flow aloft will be in place across the CWA
by early mid Monday.
At the surface, a weak frontal boundary is situated across north
central GA. This boundary will slowly move south through the day as
high pressure builds in from the north. The front will likely become
stationary across far south GA or the panhandle of FL by tonight.
The high center currently across the western Great Lakes will move
east through the day and then offshore the mid Atlantic coast by
early Monday with a wedge building in from the NE.
Most of the forecast area will remain dry through the period.
However, areas closest to the stalled boundary could see some
isolated showers and thunderstorms mainly during the afternoon and
evenings. The highest pops should be across the southern quarter of
the CWA.

Key Messages
- Warm and mostly dry conditions will persist through much of
the week ahead as ridging builds over the region.
- A late week cold front will bring increasing rain chances by
Thursday into Friday.
Surface high pressure centered over the west Atlantic will slip
gradually southward off the Carolina coastline from Tuesday into
Wednesday. Ridging will build aloft over the Southeast during this
time, providing increasingly warm conditions as well as mostly dry
conditions through midweek. Only isolated diurnal convection is
possible around the periphery of the high Tuesday and Wednesday.
The ridge will begin to flatten and shift eastward as a
shortwave ejects into the Southern Plains late Wednesday and lifts
into the Mississippi Valley on Thursday. Some timing variations
remain regarding shortwave progression during this time, but chance
PoPs will generally increase across northwest and far north
Georgia on Thursday as the shortwave lifts northeastward. By Friday,
the surface cold front looks to finally get a push southeastward
into the CWA with PoPs likely to be maximized during the day Friday
ahead of the front. At this point, there are no strong signals for
severe weather, though some diurnally-enhanced stronger storms could
occur. QPF looks fairly unimpressive as well at this juncture with
probabilities for exceeding 0.5" currently less than 30-40%.
Surface high pressure builds into the forecast area by the
tail end of the forecast period next weekend, bringing a return to
drier and at least marginally cooler conditions.
Temperatures will remain above normal through the bulk of the
period, maximized midweek when highs will primarily range from the
mid 80s to near 90 before cooler late week conditions.
