.SYNOPSIS...
High pressure will lead to mainly dry conditions and seasonable
temperatures through the weekend.
&&
.NEAR TERM /THROUGH TODAY/...
A compact mid level low pressure system will drop southeast across
the lower Great Lakes today. As it does, an associated weak cold
front will sag southeast into our area this morning before washing
out heading into this afternoon. It will be tough to rule out a few
light rain showers or sprinkles this morning across our north, but
with an overall lack of deeper moisture, think the main effect will
just be some increase in clouds. Temperatures will remain mild with
afternoon highs mostly in the low 70s.
&&
.SHORT TERM /TONIGHT THROUGH 6 PM SUNDAY/...
Surface high pressure will reestablish itself across the Ohio Valley
tonight into Sunday. This will lead to dry and mild conditions. Lows
tonight will be in the 40s with highs on Sunday in the low to
possibly mid 70s.
&&
.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
By Sunday night, large scale ridging will be moving in, amplified by
a strong area of low pressure moving through southern Canada toward
the Hudson Bay area. This allows for continued warm air advection
into the Ohio Valley region and recent model runs have come in even
warmer Monday and Tuesday, with daytime highs tickling the upper 70s
in spots along the Ohio River while overnight lows fall to the upper
40s/low 50s.
The cold front associated with this system will be dragged across
the Great Lakes region Tuesday into Wednesday, though FROPA looks to
be dry. Behind FROPA, strong continental high pressure pushes in
from Canada and temperatures look to moderate back closer to
seasonal norms, around 10 degrees cooler than previous days. Large
scale ridging and surface high pressure hang around through the end
of the working week, slowly getting shunted east as another longwave
disturbance begins to develop in western Canada.
&&
.AVIATION /04Z SATURDAY THROUGH WEDNESDAY/...
Some river valley fog will be possible through daybreak with some
IFR to VLIFR vsby restrictions affecting KLUK. Meanwhile, a weak
cold front will drop down into our area this morning. This could
lead to a few spotty light rain showers at the northern TAF sites.
Otherwise, expect to see just an increase in VFR stratocumulus this
morning into this afternoon. Surface high pressure will then develop
across the region as we head into tonight, leading to a decreasing
cloud trend through the second half of the TAF period.
OUTLOOK...No significant weather expected.
