.SHORT TERM...
(Today through Sunday)
Issued at 327 AM EDT Sat Apr 26 2025
500mb analysis shows a shortwave trough moving across the CWA early
this morning. A broken line of showers and thunderstorms developed
out ahead of the trough this evening and continues to push east
across the CWA this morning. The convection should continue to
weaken and push well east of the outlook area before sunrise.
At the surface, a cold front currently stretches from the central
Great Lakes back through the mid Mississippi River Valley. The front
will continue to push south and east today and finally through the
CWA by early Sunday. High pressure will build in from the NE later
Sunday. There isn`t a lot of forcing at the surface or aloft with
the front, but there is some minimal surface instability. Do think
isolated showers and thunderstorms could develop along and ahead of
the front during the heat of the day.
Will have to watch for patchy dense fog in the NW portion of the CWA
this morning. Clear skies, abundant low level moisture and near calm
winds will allow for prime foggy conditions.
Drier air will settle across the area tonight. Not much cooler air
expected behind the front.

.LONG TERM...
(Sunday night through Friday)
Issued at 327 AM EDT Sat Apr 26 2025
Key Messages:
-Initially drier conditions early week will trend more active by
late week.
-Temperatures remain above normal through the long term.
Surface high pressure will migrate southward from the Northeast U.S.
to settle off the Mid-Atlantic coastline by Monday. Subsidence will
generally promote drier conditions for the eastern portions of the
area on Monday, though at least isolated PoPs will be possible for
the western half or so of the area Monday afternoon around the
western periphery of the high.
Meanwhile, midlevel ridging builds over the Southeast by Tuesday as
the surface high centers off the Carolina coastline. This will kick
off a warming trend that will continue into midweek, though the
ridge will begin to flatten southeastward by Wednesday as a trough
pushes into the Plains and promotes cyclogenesis by Wednesday
night into Thursday. PoPs will initially be limited primarily to far
north Georgia on Wednesday as primary frontal forcing remains north
of the area. Coverage will trend upward Thursday into Friday as the
shortwave kicks eastward and sends the surface cold front toward the
area. While the strength and orientation of the shortwave trough
remains uncertain at this early juncture, will need to monitor for
any strong/severe thunderstorm potential.
Temperatures will be increasingly above normal through the long
term. Highs will increase from the upper 70s to mid 80s Monday to
the mid 80s to lower 90s by Wednesday into Thursday, some 8-12
degrees above normal.

Stronger convection has pushed off well to the east of the metro
area. MVFR and potentially IFR possible overnight, especially
where the heavy rainfall occurred. Winds should switch over to
the NW side shortly and remain there through the remainder of the
period. Isold shra possible along a front this afternoon, but
chances remain too small to mention at this time.
