last few areas of convective showers with a few embedded
rumbles of thunder and even some small hail will continue to
move east to northeastward out of the area this morning with
drier air with an initial cold front pushing through. winds will
begin to trend higher this morning and will increase further
with the approach of a secondary cold front associated with an
occluded low pressure system currently sitting over central ia.
this cold front will push through today and will advect in a
drier airmass and colder temperatures into the area.
temperatures in the mid 40s this morning will drop into the low
30s by this evening. any residual rain showers will begin to
change over to snow by late this afternoon and evening.
this frontal passage is accompanied by a tight pressure
gradient due to the occluded low pressure system moving eastward
through the southern great lakes and this will bring very gusty
southwesterly winds which will become more westerly later
today. gusts at times will approach 45 mph, a few locally
stronger gusts may also be possible today. a wind advisory has
been issued for the entire cwa from 7 am est this morning until
7 pm est this evening. a few strong gusts could still occur
either before the start time and just after the end time but the
majority of the strongest gusts will occur between that time.
secure loose items and lawn furniture to avoid damage.
lows saturday morning will drop into the mid to upper 20s. a
break in precipitation chances for the majority of the day on
saturday but another trough drops into the great lakes late
saturday night into sunday. this will bring snow showers across
the area with some light accumulations, mainly less than an inch
of snowfall. however, as the trough drops further southeastward
sunday afternoon into monday morning a more north to
northwesterly flow will arrive and this will produce some lake
effect snow showers, and areas nearby and adjacent to lake
michigan will see additional accumulations of about 1 to 2
inches. roads will become slick/slippery at times especially in
the heavier lake effect bands. highs on sunday will range in the
low to upper 30s with the warmer temperatures further east into
ohio. lows by monday morning will get down to the low to mid 20s
across the area. another reinforcement of colder air will
filter in with a more northwesterly flow monday and into
tuesday morning with highs on monday right around the freezing
mark and lows on tuesday morning in the upper teens to low 20s.
some slight warming will occur by the middle of the week with a
more zonal flow aloft in place. highs by wednesday will warm
into the 40s with a few locations getting around 50 degrees.
some light rain showers will be possible ahead of another trough
that will drop southeast into the region late wednesday into
thursday. this will bring some slight cooling for thursday with
highs ranging from the mid 30s northward and low 40s for
locations further south. a mix of rain and snow will be possible
mainly north of us-30 on thursday. another zonal pattern will
envelop the area by friday providing a bit of warming once again
with highs on friday in the mid to upper 40s with even a few 50s
possible. we really will be on a temperature rollercoaster for
the end of the week, and confidence in the going forecast this
far out is a bit lower pending cloud cover and exact trough
placement and strength.

predominantly mvfr conditions at the terminals, with potential
for periods of vfr/ifr. temporary vfr conditions this morning
will diminish to mvfr and potentially ifr as the low pressure
system centered over lake mi drifts e-ne through this evening.
light rain/drizzle or even a few snow showers may develop at
ksbn as a trough pivoting around the low passes this morning,
with brief dips to ifr ceilings/visibilities possible. kfwa
could see a few showers later this morning into the early
afternoon, but confidence was too low to include anything beyond
vcsh at this point. otherwise, southwest winds gusting to around
35-40 knots are expected through late afternoon, gradually
shifting more westerly with time. ceilings look to return to
high end mvfr/vfr towards the end of the period as dry air works
its way in and winds shift westerly.
