.SYNOPSIS...
High pressure will remain over the Ohio Valley through early
next week.
&&
.NEAR TERM /THROUGH FRIDAY NIGHT/...
High pressure across the region will continue to promote dry
conditions. A cool air mass remains over the region and will
allow for temperatures to drop with calm, decoupling conditions
tonight. Have issued Frost and Freeze headlines for areas still
in the program. The cool valleys and drainage areas of interior
Northeast Ohio should do well tonight with cold temperatures with
areas to widespread frost conditions elsewhere, even fairly
close to the lakeshore.
High pressure becomes more centered across the area on Friday
and return flow will allow for slowly warming temperatures. High
temperatures should reach the 60s across the area on Friday and
lows will be marginally warmer to allow for less frost for any
counties still in the program.
&&
.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
High pressure will be centered over the Ohio Valley through the
weekend. Expect dry weather with mainly clear skies, light winds,
and gradually recovering temperatures in modest south-southwest
return flow behind the high pressure. Highs will be in the upper 60s
and lower 70s on Saturday and will generally range from near 70 to
the mid 70s Sunday. Lows Saturday night will range from the mid to
upper 30s in colder spots in eastern OH and PA to the low to mid 40s
near the lake and on hilltops where winds will stay up a bit. Add
roughly 5 degrees to the lows Sunday night, mainly in the 40s.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
Ridging surface and aloft will be the story through Tuesday, leading
to mild and dry weather. A weak shortwave and cold front will cross
through Tuesday night. This will be followed by a somewhat more
potent shortwave and associated cold front Wednesday night into
Thursday. Expect minimal rain shower chances and just a slight
airmass change with the first front Tuesday night. Have greater
potential for showers (but overall light QPF/low impact) Wednesday
night into Thursday, with a more noticeable cooldown expected behind
the second front to end next week.
&&
.AVIATION /18Z Thursday THROUGH Tuesday/...
VFR conditions are expected through the period with high
pressure across the region. Some scattered low VFR cumulus
remains over the area where some light flow remains off the lake
but these clouds should disappear with the diurnal cycle and
with backing flow. Light winds expected tonight with a south to
southwest wind direction favored into Friday.
Outlook...VFR expected through Tuesday.
&&
.MARINE...
High pressure will be in control through Tuesday, leading to
generally southwest flow over the lake with 10 knot or less winds
and 2 foot or less waves. A weak frontal passage Tuesday night will
cause a brief wind shift to the west, but with speeds likely staying
under 15 knots. A stronger front will cross Wednesday night,
ushering in somewhat stronger west to northwest winds behind it for
the end of next week. No marine headlines are expected for the next
several days, with the next opportunity later next week.
