.SYNOPSIS...
High pressure will lead to dry and mild conditions through the
week.
&&
.NEAR TERM /THROUGH TONIGHT/...
An expansive surface high pressure system centered over Ontario and
extending southward into the Ohio Valley will provide for dry and
mostly clear skies again tonight. With light winds, some river valley
fog will develop later tonight. Overnight lows will be in the mid
50s to lower 60s.
&&
.SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/...
Subsidence will persist across our area Tuesday into Tuesday night
as we remain on the northwest side of the tropical activity off the
Southeast Coast. Suppose we could see some high level clouds sneak
into mainly our far southeast/east, but generally expect sunny to
mostly clear conditions to prevail. We will remain seasonably warm
with highs on Tuesday in the mid 80s and lows Tuesday night in the
50s.
&&
.LONG TERM /WEDNESDAY THROUGH MONDAY/...
On Wednesday morning, a large upper ridge will extend from the
Mississippi Valley through the Great Lakes, with surface high
pressure covering much of the Ohio Valley, Great Lakes, northeastern
states, and Ontario/Quebec. These features will gradually shift to
the east and southeast through the rest of the week and into the
weekend, but they will remain the dominant weather features for the
ILN CWA through the extended forecast period. With a very dry air
mass in place, skies will likely remain mostly clear through the
forecast period, with little if any chances for rain. The forecast
through the weekend will thus remain dry. At some point early next
week, as the ridge moves toward the east coast, some return to a
more moist flow pattern may end up occurring by next Monday or
Tuesday.
In terms of temperatures, a general downward trend will be in
progress through Wednesday and Thursday, with easterly /
northeasterly flow on the southeastern periphery of the surface
high. This will bring high temps to the upper 70s on Thursday, which
will be the coolest day of the week, but is still a few degrees
above normal. Once the high moves further east and southeast,
boundary layer flow will pick up more of a southerly component, and
a warming trend will occur through the rest of the extended forecast
period.
&&
.AVIATION /16Z MONDAY THROUGH FRIDAY/...
High pressure and a dry airmass will lead to mainly clear conditions
through the TAF period. The one exception will be the development of
river valley fog once again late tonight into Tuesday morning. This
will lead to the potential for some IFR vsbys restrictions at KLUK.
OUTLOOK...No significant weather expected.
