Now through Monday...
A closed upper low over the East Coast opens, leaving a weakening
upper trough centered along the East Coast into the weekend. This
will keep the Southeast under dry northeasterly upper flow into the
weekend in the process. Shortwave energy moving east of the
Mississippi River digs an upper trough over the river through the
weekend into the coming week, with the trough shifting east to
over the Eastern Conus in the coming week. A surface ridge
develops over the Appalachians, then builds southwest through the
rest of the week into the weekend, bringing east to southeast low
level flow to the Southeast, moving Gulf and Atlantic moisture
inland over the region. The forecast area will see an increasing
chance of showers and thunderstorms in the coming week.
A weak ridge building over the Southeast the rest of the week will
bring high temperatures rising to well above seasonal norms through
the forecast, with around 90s expected over most of the forecast
area Wednesday, then rising to the low to mid 90s by Saturday. The
advancing upper trough will drop high temperatures back into the
upper 80s to around 90 by Monday. More seasonal low temperatures in
the mod 60s to near 70 Wednesday night to the upper 60s to low 70s
for the rest of the forecast.
Weak, diurnally driven flow and decreasing tidal cycle will keep the
risk of Rip Currents Low through the weekend into the coming week.
