Area Forecast Discussion
National Weather Service Grand Rapids MI
322 PM EDT WED SEP 7 2016
LATEST UPDATE...
Synopsis/Short Term/Long Term/Marine/Hydrology
.SYNOPSIS...
Issued at 306 PM EDT Wed Sep 7 2016
A slow moving cold front will trigger several rounds of showers
and thunderstorms across the region through tonight. Locally heavy
rain and a few severe thunderstorms are possible. High pressure
will gradually move in later Thursday into Thursday night leading
to a slightly drier airmass. A strong wave of low pressure arrives
Friday night into Saturday with additional showers and
thunderstorms forecasted.
&&
.SHORT TERM...(This evening through Friday night)
Issued at 306 PM EDT Wed Sep 7 2016
Will maintain the current set of headlines with the Flood Watch
for much of the region. Pwat values are extremely high with values
up around 2.25 inches. Lcls are low and the structure of the cape
is mostly thin and deep. All this supports efficient rainfall
production with any cells. One shortwave is moving through MI
right now...with another over IA. Thus multiple lines of
convection are forecasted. A low level jet moves in tonight and
strengthens to around 50 knots. Unidirectional flow is seen above
850 mb tonight...so some training could occur. This will add to
the flood risk. Damaging winds possible in any stronger downdrafts
as the low level jet moves in. With decent 0 to 3 km Cape this
afternoon and evening...and stronger 0 to 1 km shear...there could
be an isolated tornado especially with some boundaries around.
With a stronger mid level wave moving in for Friday night...this
lift should trigger additional showers and thunderstorms...a few
of which could be strong to severe.
.LONG TERM...(Saturday through Wednesday)
Issued at 306 PM EDT Wed Sep 7 2016
A seasonably strong cold front will move through the state Friday
night. The low pushing the front through the cwa has strong upper
support. The ecmwf and gfs are in good agreement with the position
and strength of the supporting short wave. So, confidence is fairly
high that we'll see showers and thunderstorms Friday night. Although
instability is not all that high, shear values ramp up from around
20 knots to 50 kts by Saturday morning. A few of the storms could be
strong given the shear values.
We'll dry out later Saturday and Sunday as cooler and drier air
moves in. Highs will retreat to the mid 70s Saturday through Monday.
Lows Sunday night may fall into the 40s across the northern
cwa.
Another cold front will approach Tuesday. The upper support with it
isn't as strong as the Friday night system, but could still give us
scattered storms.

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 1234 PM EDT Wed Sep 7 2016
A mix of vfr and mvfr conditions will continue this afternoon with
mvfr conditions due to low clouds and reduced visbys in showers
and isolated storms. Coverage of rain and scattered thunderstorms
will likely increase late this afternoon and tonight and
conditions will briefly dip down into the ifr/lifr flight
categories in heaviest rain and thunderstorms.
Areas of fog will also develop during the early morning hours
Thursday and cause conditions to deteriorate to a mix of mainly
ifr/mvfr. Conditions will only very slowly improve from a mix of
ifr/mvfr to primarily mvfr late Thursday morning and early
afternoon as cigs/visbys slowly improve.
&&
.MARINE...
Issued at 306 PM EDT Wed Sep 7 2016
Decided to go with a small craft advisory and beach hazards for
southern parts of the Nearshore area. There is a window shown
around the low level jet tonight and Thursday morning when winds
could increase considerably. This is not certain to happen but the
risk is there so will go with a headline.
&&
.HYDROLOGY...
Issued at 306 PM EDT Wed Sep 7 2016
With pwat values over 2 inches...low lifted condensation levels
and thin deep cape...rainfall rates will be high in any
thunderstorms. The ground is already saturated from recent
rainfall...so runoff will be efficient. The flow above 850 mb is
mostly unidirectional this afternoon and tonight...so a few hours
of training is possible. As a result...will keep the flood watch
going. As for the larger rivers...it looks like it will take at
least 2 inches of basin average rainfall to trigger impacts. This
could happen so will need to monitor trends closely.
River rises are likely through the end of the week.
