Synopsis
Issued at 320 am edt Fri oct 20 2017
unseasonably warm and dry conditions will continue today into
Saturday with highs each day well into the 70s. A cold front will
move through later Sunday into Monday with chances for rain. Much
cooler weather then arrives behind this front into Tuesday and
Wednesday.

Short term (today through Saturday)
issued at 320 am edt Fri oct 20 2017
upper ridge axis builds over the region today while surface high
pressure shifts off to the east-southeast. This will result in
unseasonable warmth as low level flow becomes more southerly.

Skies will remain mainly clear under subsident stable regime
otherwise.

Mild similar conditions will persist into tonight and Saturday as
south-southwest flow deepens in advance of a deep upper trough.

Some increase in high cirrus is expected, though this should not
impact temperatures as highs once again reach well into the 70s.

Long term (Saturday night through Thursday)
issued at 320 am edt Fri oct 20 2017
the aforementioned upper trough will fracture eastward with
southern energy into the lower mi valley and northern stream jet
energy more focused through the western northern lakes. This will
force a slowing weakening frontal circulation east through the
area later Sunday into early Monday. Good moisture return within
llj core and decent right entrance jet dynamics height falls
should allow for a period of rain along the front. However, expect
line to narrow and diminish a bit in intensity as it shifts east
into the local area during this time. Temperatures will once again
be well above normal into Saturday night Sunday otherwise.

Strong pacific jet energy does eventually carve rather substantial
negative height anomalies into the great lakes and ohio valley by
Tuesday and Wednesday. A brief intrusion of much cooler air will
be the result as strong CAA wing wraps in with lake
enhanced effect showers under deep trough. Models continue to
suggest at least a partial phase with leftover lower ms valley
shortwave in the transition later Monday-early Tuesday. The gfs
continues to be weaker farther east (drier) while the ecmwf
remains more phased less progressive with a much wetter solution
locally (1-2 inches of rain). Will cover these periods with chance
pops at this range given the differences.

Aviation (for the 18z tafs through 18z Saturday afternoon)
issued at 1255 pm edt Fri oct 20 2017
not much has changed since the previous forecast. Expect light
winds out of the south under mostly clear skies.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
