area forecast discussion... Updated

728 pm est Sun feb 17 2019

Synopsis
A wintry mix of precipitation can be expected through tonight
with passing low pressure. Snow showers will linger on Monday,
and then a dry and seasonably cold Tuesday is expected under
high pressure.

Near term until 6 am Monday morning
Extended the wsw until 1am for much of the area, as freezing
drizzle is developing behind the main precipitation field. Pops
have been updated accordingly with current radar trends and
hires model guidance.

Previous discussion...

a typically challenging precipitation type forecast dominates
for tonight. Mid-level dry air is still slated to arrive
tonight, which will remove much of the ice nuclei and raise the
potential of drizzle freezing drizzle. Have kept this in the
grids after midnight. An extension expansion of the advisory for
this threat is also a possibility. Coverage of more substantial
showers will slowly decrease toward morning.

Short term 6 am Monday morning through Tuesday
Scattered northwest flow snow showers will continue into Monday
afternoon for much of the region, perhaps into the evening
hours along the southeast ridges. Modest snow totals of an inch
or less are foreseen for now given fairly meager moisture in the
dendritic growth layer and low inversion heights. However, some
decent lapse rates are indicated below these inversions, so the
possibility of a few heavier snow showers will need to be
considered.

Advancing high pressure will cut off the snow showers, and
clouds will decrease through Monday night. Some sunshine is
anticipated Tuesday, before mid and high clouds begin to
increase later in the day. Temperatures through this period will
run a bit below seasonal norms.

Long term Tuesday night through Sunday
Another messy system will move into the region Tuesday night
into Wednesday and Wednesday night. Many places will likely see
both some minor snow and freezing rain accumulation. This storm
is already mentioned in the hwo. Model solutions waver on what
will happen with the next system. Right now the ECMWF and gfs
both show a system that should remain to the south of the region
Thursday and Friday, but the GEFS keeps this storm a bit
farther to the north. Have hedged with chance pops across the
southeast and slight chance pops for most other locations. The
next storm system begins to wrap itself together by Sunday
morning, moving across michigan and continuing on to the
northeast. Considering the storm track, precipitation should
generally be rain by day and snow by night. Temperatures will be
slightly above normal through the period.

Aviation 01z Monday through Friday
Conditions will deteriorate to ifr areawide, with potential for
lifr CIGS mixed in as a sfc low passes over the region. Given
current sfc temps and the lack of notable warming overnight,
added freezing drizzle for most sights until the sfc cold front
moves through and makes the boundary layer too turbulent for
drizzle.

Conditions will slowly improve after this frontal passage
through the rest of the day Monday. However, the switch to nw
flow will aid the development of lake enhanced snow showers
which will reinforce lower ceilings and create brief periods of
lower visibilities. These factors will likely keep MVFR
conditions in the area the entire day.

Outlook
Brief period ofVFR expected with high pressure Tuesday before
the next low pressure system reintroduces pcpn and widespread
restrictions Wednesday.
