.SYNOPSIS...
High pressure builds east over Ontario this evening as
low pressure move into the region from the west. A warm front will
lift north Tuesday into Wednesday with the cold front moving through
on Wednesday. The low will exit to the east late Wednesday as high
pressure builds into the region on Thursday.
&&
.NEAR TERM /THROUGH TUESDAY NIGHT/...
High pressure creating dry and cool conditions will continue through
this evening into Tuesday. A low pressure system will push into the
Great Lakes region early on Tuesday with the accompanying warm front
moving north across the area. Precipitation chances will increase
Tuesday afternoon as the low pressure system approaches. There will
be a low potential for strong thunderstorms with strong winds being
the main threat, though this will be isolated given the weak shear
lack of forcing. Timing will be key as well as it will be focused
more during the afternoon/early evening on Tuesday for areas west of
I-77 ahead of the cold front. Confidence is low in severe potential
for that time period and the potential will dissipate as the front
progress east after sunset. Temperatures overnight tonight will be
cool with lows in the low 60s to upper 50s. Some low areas out east
may dip down into the low 50s as well. High temperatures tomorrow
will rebound slightly from today with passing warm front and be in
the mid 80s.
&&
.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
Low pressure will exit the region to the east by mid Wednesday as
high pressure builds in from the west. A dry forecast is expected as
the high moves across the Great Lakes region Wednesday evening and
throughout the day on Thursday. Temperatures will be cooler behind
the cold front with highs in the low 80s as north to northeasterly
flow takes over. Overnight lows will be in the mid to low 60s down
to the upper 50s in the far eastern portions of the area.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
High pressure will build eastward throughout the day on Friday as a
surface low develops in south-central Canada. The low and
accompanying cold front will move eastward across the region on
Saturday into Sunday bringing potential for showers and
thunderstorms. High pressure will begin to build into the region on
Sunday into early next with dry weather and cooler temperatures
expected. Through the weekend highs are expected to be in the mid
80s for Friday and Saturday and drop down into the upper 70s behind
the front on Sunday. Overnight lows will follow a similar pattern
being the mid to low 60s then dropping into the 50s behind the cold
front.
&&
.AVIATION /00Z Tuesday THROUGH Saturday/...
VFR conditions are anticipated through the majority of the TAF
period. Skies will be mostly clear to partly cloudy tonight.
Clouds will increase but stay mostly VFR on Tuesday. There could
be some MVFR ceilings at TOL and NWOH by Tuesday afternoon. A
weak cold front will move into the NWOH Tuesday afternoon with
scattered showers and isolated thunderstorms possible. Winds
will be starting out from the northeast to east tonight 5 to 10
knots. A few gusts up to 20 knots are possible for ERI this
evening. Winds will generally become southeast 5 to 10 knots
Tuesday morning then becoming southwest Tuesday afternoon.
Outlook...Non-VFR conditions possible with showers and
thunderstorms Tuesday afternoon through Wednesday evening.
Additional non-VFR possible in showers and thunderstorms on
Saturday.
&&
.MARINE...
Northeast winds to 10 to 20 knots and waves of 2 to 5 feet will
continue around and east of the Islands through this evening and
a Small Craft Advisory and Beach Hazards Statement remain in
effect until 10 PM EDT this evening. Conditions are a bit
marginal from Geneva-on-the-Lake OH to Ripley NY, however
guidance suggests that there could be a brief uptick in
winds/waves this evening so opted to maintain the headlines.
Winds will become southeasterly and diminish to 6 to 12 knots
overnight before diminishing further and shifting to the south
Tuesday afternoon.
Winds are expected to become more variable and increase to 6 to
12 knots as low pressure moves east across the lake Tuesday
night into Wednesday with northeast winds increasing to 10 to 15
knots behind the low Wednesday afternoon through Thursday.
There may be a period where winds approach 20 knots and waves
near 3 to 5 feet during this time; Small Craft Advisories and
Beach Hazards Statements may need to be considered if
winds/waves trend higher. Flow will become lighter and more
variable Friday before winds shift to the southwest and increase
ahead of an approaching cold front Saturday.
