the Labor Day weekend. Temperatures will be a bit below normal
for the next couple of days, but, warm back above normal over the

Strong cold front was working steadily SE across the forecast area
with a broken line of showers and a occasional lightning strike.
Despite decent instability...organization has been limited resulting
in main threat will be a period of heavy rainfall. Timing out of the
area should be around 00Z. Highest pops reflected along/ahead of the
front with isolated mention ahead of it. Dry air was rapidly working
in behind the front with only concern after this being high risk
of rip currents into Thursday. Waves already rocking along the SE

High pressure will dominate conditions across the region with any
major upstream changes hampered initially by remnants of "Hermine"
that will likely be raising havoc along the East coast. Med range
models suggest disruption in the upper flow may keep dry conditions
in place through at least Monday. Will have some pops in at the end
of the period but otherwise will maintain dry forecast with slow
warming trend to above normal levels.
