An upper level ridge will build into the region and bring mild 
temperatures to the area over the next several days. Highs in the
65 to 70 degree range will moderate into the lower to middle 70s
by this weekend. Chances for rain increase Saturday night ahead 
of a strong cold front that will bring much colder weather to the 
area early next week.


.SHORT TERM...(This Evening through Wednesday)
Issued at 344 PM EDT Tue Oct 17 2017

Return flow will continue through Wednesday as the center of a large 
high pressure area drifts to the mid-Atlantic Seaboard. After winds 
of 5 to 10 mph tonight, winds will increase Wednesday with daytime 
heating and mixing to 10 to 20 mph with some gusts above 25 mph by 
afternoon. Very limited moisture will be available for clouds, so 
clear to mostly clear conditions will prevail.


.LONG TERM...(Wednesday Night through Tuesday)
Issued at 344 PM EDT Tue Oct 17 2017

Several more warm and dry days are ahead as an upper level ridge 
builds toward the Ohio River Valley. Temperatures should rise at 
least 10 degrees above normal at times through the end of the week. 
The pattern should start to break down by late this weekend as a 
large upper level trof becomes negatively tilted toward the Upper 
Great Lakes region. It looks like the colder air will come in 2 
stages, with the secondary and stronger cold front moving across the 
area Monday night. Favor the GFS handling of this system that has 
been reasonably consistent since Monday morning. After coordinating 
with neighboring offices, have lowered Tuesday high temperatures of 
the model blend significantly given very chilly air with 850 mb 
temps near 0C per GFS and EC and given clouds and showers.


.AVIATION...(For the 06Z TAFS through 06Z Wednesday Night)
Issued at 1234 AM EDT Wed Oct 18 2017

VFR conditions to prevail through the period and beyond.
Mixing of somewhat stronger wind fields aloft will occur once
inversion is lost with some gusts near 20 kts. Quick loss of gustiness
will occur after 00Z.
