Synopsis
Issued at 309 am edt Wed mar 29 2017
a ridge of high pressure will track eastward through michigan
today. This fair weather system will provide the region with dry
weather. Clouds will thicken up during the day as a low pressure
system approaches from the southwest. This system will spread a
mixture of precipitation types to the area late tonight... That
will transition to all rain during the day on Thursday. The wet
and cool weather will then persist into Friday.

Short term (today through Friday)
issued at 309 am edt Wed mar 29 2017
the main challenge in the short term deals with the potential
impacts for later tonight through Thursday. Overall it appears
parts of interior lower michigan could see some impacts mainly
from wet snow.

We are going to have to monitor this system carefully and may have
to make bigger adjustments to the forecast with time. The cooling
and drying airmass that we currently have in place is lowering the
wet bulb temperatures down ahead of the approaching storm system.

This will act to create more of a snow sounding when the steadier
precipitation moves in later tonight. Fgen strengthens
overhead... With favorable upper jet setup suggests the
precipitation could organize into a band... Especially after
midnight or Thursday morning. Up high... Weakness in the stability
could support a period of higher snow rates. Currently the
northern row or two of zones in my CWA look to be at the greatest
risk with the main window from 09z to 18z. This would include the
area along and north of a mount pleasant to big rapids line. Still
some uncertainty as mixed precipitation could occur and low level
temperatures may struggle to fall below freezing possibly
limiting impacts. We will continue to highlight the potential in
the hazardous weather outlook and social media.

Low level wet bulb temperatures are still not far from snow going
into Thu evening. If this system trends a little colder... Snow
could persist even into Thu afternoon and evening. Stay tuned.

Long term (Friday night through Tuesday)
issued at 309 am edt Wed mar 29 2017
there may be a few lingering showers Friday night as low pressure
moves east across northern ohio, otherwise the weekend looks dry with
highs in the 50s as high pressure builds in behind the departing low.

The next chance for measurable rain comes late Monday and Monday
night as low pressure moves from the plains east across the ohio
valley. Most of the precipitation associated with this system will
stay south of michigan. However, the southern CWA will see the
highest chances for light rain. Highs Monday and Tuesday will be in
the 50s.

Aviation (for the 12z tafs through 12z Thursday morning)
issued at 738 am edt Wed mar 29 2017
patchy fog this am will quickly dissipate given the dry airmass in
place. High clouds will thicken up during the day with the bases
lowering into the evening... But still remainingVFR. Then after
midnight precipitation will be developing and moving in. It looks
like a mixture of rain and snow will be possible for kgrr and
kmkg... With mainly rain elsewhere. For now I put MVFR conditions
in the forecast for later tonight.

Marine
Issued at 309 am edt Wed mar 29 2017
with a largely offshore wind... No marine headlines are expected
today to tonight.

Hydrology
Issued at 320 pm edt Mon mar 27 2017
most rivers have demonstrated within bank rises after rainfall over
the last 4 days. However, more elevated river levels at ionia,
hastings, eagle, and holt may be susceptible to additional rainfall
expected Thursday and Friday, possibly another 0.50"-1.00". This may
act to provide secondary river crests heading into the end of the
week and weekend, potentially higher than the current crests.
