.SYNOPSIS...
High pressure will maintain influence over the region today. A
weak cold front may clip the eastern fringe of the forecast
area early Tuesday before strong Canadian high pressure builds
southeast over the northeastern United States Tuesday through
the end of the week.
&&
.NEAR TERM /THROUGH TUESDAY/...
High pressure will remain over the region through the near term
period, although a weak (and dry) cold front could clip NW PA
and possibly Northeast Ohio late tonight into early Tuesday.
Behind this feature, strong Canadian high pressure will build
southeast across the northeastern CONUS and Lower Great Lakes.
Dry weather is anticipated through Tuesday, although the air
mass will begin to cool a bit starting Tuesday. Today`s highs
will be in the 70s and lower 80s with the coolest temps in the
low to mid 70s anticipated close to the lakeshore with the
warmest temps in the mid to possibly upper 80s expected across
interior northwestern and north-central Ohio from roughly Knox
County to Hancock County. Tonight`s lows will generally be in
the 50s. Tuesday`s highs will be a few degrees cooler in the
upper 70s to lower 80s at inland locations with breezy onshore
winds producing highs in the low to mid 70s along the lakeshore.
Patchy to fog will likely develop at inland locations during
the predawn hours today. As of now, fog related headlines
probably won`t be needed since widespread reduced visibilities
are not expected, but will continue to monitor satellite and
observations as the sunrise approaches.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
The aforementioned Canadian high will continue to build
southeast across the northeastern CONUS through the short term
period, resulting in cooler temperatures and continued dry
weather. Temperatures will be in the 40s across most of the area
Tuesday night, however breezy northeast flow will advect warmer
temperatures off of Lake Erie with 50s and lower 60s anticipated
across NW OH. Wednesday will be the chilliest day of the week
with highs in the 60s and lower 70s anticipated. Widespread lows
in the 40s are expected Wednesday with a few spots likely
dipping into the upper 30s across the higher terrain of far NE
OH/NW PA. Winds will be too elevated for frost development and
there may be some high clouds that could limit radiational
cooling. However, a few spots as far west as the I-71 corridor
could attempt to fall into the upper 30s if cloud cover ends up
being lower than currently forecast. Thursday`s highs will be
in the upper 60s to lower 70s across most of the area, however
southwestern zones will likely see max temps in the mid to upper
70s. Thursday night`s lows will largely be in mid 40s to lower
50s.
&&
.LONG TERM /FRIDAY THROUGH SUNDAY/...
The high will settle over the Mid-Atlantic Friday through the
weekend. This will place the local area on the western flank of
the high, resulting in the return of southerly flow and warming
temperatures during the long term period. The dry period will
continue through the weekend as upper ridging persists over the
eastern Great Lakes. Highs are expected to gradually rise
Friday through Sunday with mid 70s to lower 80s anticipated by
Saturday and Sunday.
&&
.AVIATION /06Z Monday THROUGH Friday/...
VFR conditions will continue for this TAF update and through
Monday evening. Skies will remain mostly clear through the nest
24 hours. There may be some patchy light fog around TOL, MFD,
CLE, and YNG early this morning with 5sm BR between 09z and 13z.
Otherwise, quiet weather is expected for aviation.
Light and variable winds are expected for the rest of tonight
into Monday morning. A light lake breeze may bring north-
northeast winds around 5-8 knots Monday afternoon.
Outlook...Patchy fog possible early Monday morning and Tuesday
morning. VFR otherwise.
&&
.MARINE...
High pressure over the Great Lakes will continue to keep the
weather very quiet this week. Winds will be light and variable
with a trend to favor a light onshore flow today and tomorrow
with a lake breeze. There will be a trend to favor a light
offshore flow at night. High pressure over Ontario will
gradually moves to southern Quebec and New England through the
end of this week. A stronger Northeast flow will start to
develop on Tuesday, strengthening to 20-25 knots as well as
higher waves Tuesday night through Wednesday night. A small
craft advisory is very likely for most if not the entire
southern nearshore of Lake Erie during this time frame or mid
week period. Winds will become lighter and Easterly by the end
of the week. By Friday, a light southerly or offshore flow will
return over the lake.
