.SYNOPSIS...
Issued at 210 PM EDT Wed Oct 10 2018 

A cold front will swing through the area this evening with showers 
and an isolated thunderstorm possible. Expect much more fall like

.SHORT TERM...(Tonight and Thursday)
Issued at 210 PM EDT Wed Oct 10 2018

Swd trailing cold front in association with deepening sfc cyclone 
over wrn WI will accelerate ewd this evening. Disorganized broken 
band of showers along prefrontal trough will work quickly eastward 
and end west to east mid evening. Strong post frontal low level cold 
advection then follows on Thu with gusty wrly winds.

.LONG TERM...(Friday through Tuesday)
Issued at 210 PM EDT Wed Oct 10 2018

Remarkably colder this period compared to prior unseasonably warmth. 
Vigorous deep layer troughing to manifest across se Canada in 
response to secondary strong disturbance amplifying through James 
Bay Sun night followed by tertiary additional wave Wed. Net effect 
will be increasing low level thermal trough developing across the 
Great Lakes as successive influxes of cold advection carve sewd 
behind each shortwave. Accompanying cold fronts will be moisture 
starved and orphaned from stronger dynamics aloft thus mainly dry 
and unseasonably cool through the period.

.AVIATION...(For the 00Z TAFS through 00Z Thursday Evening)
Issued at 727 PM EDT Wed Oct 10 2018

Pre-frontal trough working east across area with narrow line of
mainly showers. Sfc obs indicate some gusty winds along southern
portion of this line with gust to near 30 knots at KLAF as it
moved through. This line will be clear of KSBN at 00z and should
move through KFWA between 01 and 02z. Satellite and sfc obs also 
show chaotic cigs with conditions variable from VFR to IFR. Should
eventually see cigs settle to MVFR range as upstream solid 
stratocumulus deck and main cold front advancing through IL 
push through our region and cloud deck likely persists into 
at least mid day Thursday.
