Area Forecast Discussion

338 AM EDT Fri Oct 18 2024
.SYNOPSIS...
High pressure will persist into the start of next week.
&&
.NEAR TERM /THROUGH SATURDAY NIGHT/...
Pleasant fall conditions will persist into the weekend as high
pressure remains dominant east of the Mississippi River. This
will keep conditions dry with mostly clear skies. These clear
skies will allow the daytime highs to climb into the mid to
upper 60s today. These will warm a bit more on Saturday as
clear skies mixed with southwesterly winds and WAA bring
temperatures close to 70 for many areas. Overnight lows will
still remain quite cold, dropping into the low to mid 30s as a
result of increased radiational cooling. As a result to these
temperatures, frost and freeze conditions remain possible across
the area tonight.
&&
.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
Low RH atmosphere and surface high pressure will continue to
dominate the sensible weather as we head through the end of the
weekend and into early next week. With 850mb temperatures into the
low/mid teens, enough insolation and primarily southwesterly surface
flow allows for upper 60s to 70s across the CWA, with Monday
slightly warmer than Sunday. Very quiet weather pattern for mid
October overall.
&&
.LONG TERM /TUESDAY THROUGH THURSDAY/...
Finally getting into a pattern change in the extended portion of the
forecast. Upper level low ejects out of the four corners region to
the mid Mississippi Valley, filling while it tracks eastward. Should
become an open wave by the time it reaches the southern Great Lakes
and do not anticipate much more than some cloud cover at this point.
This will be followed quickly by a cold front from a higher
amplitude trough axis aloft in the norther stream. Finally get into
some POPs again for the Wednesday through Thursday time frame, and a
cooler airmass trending for the end of the work week.
&&
.AVIATION /06Z Friday THROUGH Tuesday/...
Widespread VFR conditions will persist for much of the area
through this TAF period. With light winds tonight and a moist
lower level, there is a potential for patchy fog to develop
across counties east of I77. Highest confidence in fog
development is within the river valleys across the area however
confidence in the extent/development of this fog elsewhere
remains low, so opted to not include it in the TAF. Any
terminals impacted will likely have reduced visibilites to MVFR
distances. Winds will persist as light and variable through the
period, with a weak land breeze persisting through morning and
again occurring tonight.
Outlook...VFR expected through Tuesday.
&&
.MARINE...
Quiet lake conditions under high pressure with winds generally
southwesterly through the weekend and nearshore wave heights around
a foot or less. Southwest winds increase to 10-15kts ahead of a cold
front Wednesday which could increase the nearshore wave heights to
around 2 feet from Cleveland eastward through Dunkirk.
