Issued at 705 AM EDT Mon Mar 19 2018

Our stretch of quiet and warmer weather continues today, with high
temperatures into the 40s and low 50s. It will be breezy today and
tonight, with increasing clouds across the south. Lows will drop
into the 20s. Light snow is expected Tuesday and Wednesday, with
minor accumulations possible in locations south of highway 24,

.SHORT TERM...(Today through Wednesday)
Issued at 401 AM EDT Mon Mar 19 2018

An upper level system will move across the far southeast portion
of the area from Portland to Lima. Light snow accumulations of up
to 2 inches are possible from Tuesday into Wednesday as the
deformation zone associated with this system lingers over the
area. Temperatures will be much below normal Tuesday and Wednesday
with highs only around 40.


.LONG TERM...(Wednesday night through Sunday)
Issued at 401 AM EDT Mon Mar 19 2018

Waves of energy of pacific origin will be transported east late
this week and over the weekend across the upper level jet highway
and into the Midwest. These systems will bring plenty of potential
for rain and the possibility for accumulating snow. Still some
uncertainty about timing and location details, but an active and
wet pattern is looming from Friday into this coming weekend. A
rain and snow mix is likely from Friday night through Saturday as
thermal profiles hover close the the rain/snow threshold.
Otherwise, temperatures most days this week will be 5 to 10
degrees below normal with highs mainly in the 40s.


.AVIATION...(For the 18Z TAFS through 18Z Tuesday Afternoon)
Issued at 100 PM EDT Mon Mar 19 2018

VFR this period as ridging sfc and aloft persist across the Great
Lakes. Low pressure lifting through the TN valley tonight/Tue will
lead to increasing e-nerly flow with sfc gusts aoa 20kts at times.
