Synopsis
Issued at 315 pm edt Thu jun 20 2019
- drying out Friday through most of Saturday
- unsettled and stormy period at times Sunday through Tuesday
- quieting down briefly next Wednesday

Discussion (this evening through next Thursday)
issued at 315 pm edt Thu jun 20 2019
our attention is starting to transition from the rain event last
night and this morning, to the next potential wet period that looks
to be Sunday through Tuesday.

The last of the rain from this last system is just about to exit
east of the area as of 19z 3 pm edt this afternoon. We should see a
mostly dry couple of days as a fairly sharp upper ridge slowly
builds over the area, and a canadian sfc ridge funnels drier air
over the area. The ridge will only slowly build east, helping to
keep the drier air in a little bit longer. It is possible that a mcs
may come as close to us as chicago Fri night Sat morning. It looks
like the instability gradient and flow will stay just far enough sw
to allow for a dry forecast into Saturday.

The better chance for storms will come in beginning on Sunday. This
is the case as the long wave trough over the plains will lift a sfc
low to the ne, and give the warm front instability gradient enough
of a push to make it over the area. It appears that there will be
multiple waves that move through in the SW flow aloft. Tough to give
any details about a complicated situation with short wave activity,
timing, degree of instability etc... However, we will have the
potential to build decent instability at times, the flow aloft will
be conducive for organization of storms, and we will have plenty of
deep moisture to work with. This could end up being a fairly busy
period at times with severe weather and some flooding possible.

We should see the system move out by Wednesday, which would allow
for the area to dry out again with high pressure building overhead.

Right now, this dry period looks limited in duration as short waves
look to move toward the area again on Thursday.

skies are clearing from the north as I write this. I would think
by 06z all TAF sites should be clear. Winds will be light but
there is enough dry air that I do not think fog will be an issue
but given the amount of rain that fell, and that the winds are
light, I would watch carefully at azo, btl and to some extent jxn
and grr between 06z and 12z for dense fog. Whatever fog does
develop it will mix out quickly Friday after sunrise. Expect
nearly clear skies all day Friday at all TAF sites. Winds will be
light too.

Marine
Issued at 315 pm edt Thu jun 20 2019
weather impacts to mariners will be rather limited through Saturday,
with winds expected to be under 20 knots. Impacts look to ramp up a
bit for Sunday, and will last through Tuesday as a fairly decent
sized system slowly moves through the region. We are looking at
small craft advisories being likely during that time frame, along
with multiple chances of stronger storms.

Hydrology
Issued at 315 pm edt Thu jun 20 2019
the rain event from last night through this morning is winding down
across the area. Rainfall amounts ranged from around an inch up
north, to as much as locally around 5 inches around the kalamazoo
area. The flood advisory for most of the southern two rows of
counties (except jackson county) was extended into Friday with roads
closed, and standing water remaining in place. Two river points are
under a flood warning, eagle on the looking glass river, and
vicksburg on the portage river are forecast to come up to flood
stage. The rest of the rivers are still expected to see significant
rises, but staying within their banks.

We will have a chance for things to stabilize a bit, with what looks
to be almost 48 hours of dry weather and sunshine with longer days.

However, we will need to watch the period from Sunday through
Tuesday closely. There looks to be a potential of multiple rounds of
storms with the next system expected to affect the region for a few
days. Locally heavy rainfall will be possible with each round, which
will not be good on saturated soils from this recent event.
