.DISCUSSION...
Issued at 332 PM EST Sun Feb 8 2026
- Not much precip with the next clipper
A northern stream shortwave trough and clipper low tracks north
of Lower Michigan Monday into Tuesday. An area of warm air
advection and isentropic ascent could bring light snow or mixed
precip into the northern forecast Monday night, but moisture
profiles look rather dry so slight to chance POPs look good for
now. QPF expected to be trace to a couple hundredths so impacts
of any frozen or freezing precip should be limited.
Temperatures moderate briefly before cold air returns for mid-
week as the clipper moves east and Canadian high pressure builds
in. Inversion heights remain AOB 5 kft AGL with fairly dry
soundings, so there are currently no POPs for Tuesday night and
Wednesday. It`s still possible POPs would need to added if
moisture profiles look more promising in the northwest flow
following the cold FROPA on Tuesday.
- Late Week Storms may stay south
An active southern stream is expected during the latter half of
the week and into next weekend, but the longer range guidance has
trended towards keeping the surface low tracks further south with
a separate northern stream and any phasing holding off until
perhaps next week. So only chance or slight chance POPs in the
current forecast for Thursday night and again over the weekend as
deep moisture/surface lows remain well to the south of Lower
Michigan.
