Area Forecast Discussion
National Weather Service Grand Rapids MI
743 AM EDT Mon Oct 23 2017

LATEST UPDATE...
Aviation

.SYNOPSIS...
Issued at 317 AM EDT Mon Oct 23 2017

Rain, occasionally heavy, will spread across the area this afternoon
and last much of tonight. Rain will continue Tuesday before
tapering off Tuesday night. Rain showers will be less frequent for
the latter half of this week. Temperatures will be seasonably
cool with highs in the upper 40s to low 50s for much of the week.
It will feel blustery Tuesday and Wednesday with gusty winds.

&&

.SHORT TERM...(Today through Tuesday)
Issued at 452 AM EDT Mon Oct 23 2017

Have expanded the flood watch westward to encompass the entire forecast
area. The focus for the heaviest rain has shifted northwest and
there now may be a reduced threat for heavy rain along the US-127
corridor around Lansing and Jackson. We will keep this area in the
watch however given uncertainty in the details. It is looking
increasingly likely that a sizable part of the forecast area could
receive 4-5 inches of rain, most of which will fall from this
afternoon into Tuesday morning, which could impact commutes this
evening and especially Tuesday morning. There are indications
that significant rainfall accumulations could continue well into
the day Tuesday, boosting totals even further.

We are close enough in time to the event to utilize convection allowing
models. Not surprisingly, they advertise much greater QPF due to better
depiction of the impressive fgen that is too narrow to be properly
resolved by the global models. It's looking more likely that the
deformation/fgen area will rotate over the forecast area this
evening. This will result in prolonged durations and greater coverage
for rainfall. With the rotation of the mid-level thermal gradient comes
a significant Fs contribution to the mid-level frontogenesis further
boosting upward vertical motion and precipitation rates. Atmospheric
moisture remains rather extreme for this time of year. The 00Z
APX and GRB soundings were 265 percent and 185 percent of normal,
respectively. Therefore the environment supports intense rainfall
rates.

A peek at the 23/00Z ECMWF reveals that additional rainfall Tuesday
could be significant particularly to the northeast in the vicinity
of Mount Pleasant and Clare. In fact, these areas may end up with
the greatest totals by the middle of the week.

.LONG TERM...(Tuesday night through Sunday)
Issued at 452 AM EDT Mon Oct 23 2017

Rain showers will be diminishing in coverage Tue night, however they
will not quite come to an end until probably Wed night. The sfc low
and associated wrap around pcpn will shift out, taking the heavier
rainfall with it. The long wave upper trough will hold in across the
area, and another short wave will dive SE over the area on Wed.

We will likely see a reprieve in the rain showers on Thu as we will
be sitting in between storm systems. A short wave upper ridge will
control the weather between the departing low, and the next low
poised to move in from Canada. Temperatures will try to recover some
with a solid srly gradient ahead of the next system, and some
possible sunshine.

Rain shower chances will reappear on Fri, and will linger off and on
through the weekend. The next cold front will pass through early
Friday, with the secondary cold front with the upper wave coming
through Friday evening. A break looks possible late Sat and early
Sun before yet another upper low digs SE across the area. These
showers have the potential to mix in with some snow at night with
temps dropping into the 30s and freezing heights approaching the
sfc.

&&

.AVIATION...(For the 12Z TAFS through 12Z Tuesday morning)
Issued at 743 AM EDT Mon Oct 23 2017

IFR conditions will predominate through at least 00Z this evening with
perhaps some brief MVFR. A rather narrow north to south band of moderate
to heavy rain positioned near the lakeshore this morning will move
slowly eastward today, resulting in deteriorating conditions from
west to east at the terminals. Winds from the northwest will intensify
tonight resulting in another threat for low level wind shear.

&&

.MARINE...
Issued at 452 AM EDT Mon Oct 23 2017

Based on latest WW3 guidance and in coordination with other
offices, went with a small craft advisory areawide beginning
this evening and a gale watch areawide beginning Tuesday morning.

&&

.HYDROLOGY...
Issued at 310 PM EDT Sun Oct 22 2017

Showers will spread into the area from the west through this
evening, with coverage of rain filling in overnight. This looks to
bring about a half-inch of rain to west Michigan by about 8AM Monday
morning. Rain may be moderate in intensity at times, but is not
expected to cause flooding overnight.

There should be a brief decrease in shower activity Monday morning
before another round of rain develops over Lower Michigan Monday
afternoon and lasts into Tuesday. Most locations look to receive at
least an additional inch of rainfall, but a north-to-south
orientated swath of heavier rain, with amounts of possibly 3 to 5
inches, is expected over the Lower Peninsula. At this time, it looks
like this heavier swath of rain will be located somewhere between
U.S. 131 and the Detroit-area. A Flood Watch therefore remains in
effect for counties generally east of U.S. 131. Localized flooding,
ponding on roadways, and rises in rivers, creeks, and streams could
occur within the area of heaviest rain. Confidence in the location
of the heaviest rain is not high, and refinements to the forecast
are still possible.
