Area Forecast Discussion

.SYNOPSIS...
A weak surface trough will linger near Lake Erie through this
evening before shifting eastward. The area will remain
influenced by high pressure centered over the New England and
Mid Atlantic regions through the weekend.
&&
.NEAR TERM /THROUGH THURSDAY NIGHT/...
Scattered showers and storms may impact portions of northwest
Ohio, where fairly unstable conditions have developed this
afternoon with 500-1000 j/kg MLCAPE. Have maintained chance pops
for the next several hours, with precip chances expected to
quickly wane after sunset. Convection should remain widely
scattered, although slow storm motions may produce some brief
heavy downpours. Elsewhere, some lingering isolated showers over
far northeast Ohio and northwest PA should end over the next
several hours as an upper trough continues to move east away
from the area.
Conditions will remain dry overnight through Thursday night with
high pressure largely in control across the area. Have
maintained a dry forecast tomorrow despite some hi res guidance
hinting at a very isolated shower or two, but a lack of forcing
and much lower to non-exsistant instability precludes any pops
at this time. Lows tonight in the upper 50s to low 60s, with
lows a few degrees warmer Thursday night. Highs on Thursday in
the low to mid 80s.
&&
.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
Ridging remains the dominant synoptic weather feature over the
region Friday through Saturday night. Have maintained a dry
forecast at this time, but will need to watch potential upstream
MCS activity working into the northwest part of the area early
Friday. This remnant activity could bring some precipitation to
the area depending on the track, but confidence too low for
explicit forecast mention. Temps continue to warm into the
weekend with southerly flow, with highs Friday in the mid to
upper 80s and high Saturday in the mid 80s to low 90s.
&&
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
A more active pattern begins to setup by early next week, as
ridging remains entrenched across the eastern CONUS. However,
low amplitude upper trough attempts to slide eastward into the
Great Lakes region by midweek. This could bring a cold front to
the area by Tuesday or Wednesday, but models are trending a bit
slower. Above normal temps will persist into early next week,
then depending on the timing of the cold front, we could see
more seasonable temps by midweek, but odds still lean to
slightly above normal at this time.
&&
.AVIATION /18Z Wednesday THROUGH Monday/...
VFR will dominate through Thursday as high pressure strengthens
across the region. A weak trough crossing the region this
afternoon will combine with daytime heating to generate a few
widely scattered showers and thunderstorms over NW Ohio and in
NW PA. Coverage is low confidence, and it is possible that all
sites remain completely dry, but added VCTS at KFDY, and kept a
TEMPO for showers at KERI. As high pressure strengthens tonight,
all sites will be dry and VFR.
S to SE winds of 5-10 knots this afternoon will become light and
variable tonight then S to SE at 5-10 knots again Thursday. A
lake breeze will turn winds NE for a few hours at KCLE and KERI
this afternoon and again Thursday afternoon.
Outlook...VFR largely expected through Monday. There is
potential for some non-VFR visibility every morning in typical
locations for valley fog.
&&
.MARINE...
Quiet marine conditions are expected as high pressure
strengthens across the Great Lakes the rest of the week and
persists through early next week. This will result in generally
light S winds averaging 5-15 knots, but daily lake breezes will
turn winds E to NE each afternoon. SW winds will increase ahead
of a cold front slowly approaching the region Monday and
Tuesday, and expect SW winds of 10-20 knots, especially by
Tuesday.
