Area Forecast Discussion
National Weather Service Grand Rapids MI
331 PM EDT Tue Jun 22 2021

LATEST UPDATE...
Synopsis/Discussion/Marine

.SYNOPSIS...
Issued at 330 PM EDT Tue Jun 22 2021

- Warm advection showers Wednesday

- Brief break Wednesday night into Thursday morning

- Periods of storms with significant rainfall Thursday to
  Wednesday

&&

.DISCUSSION...(This evening through next Tuesday)
Issued at 330 PM EDT Tue Jun 22 2021

- Warm advection showers Wednesday

The convection from the northern stream shortwave will be out of
this area by early this evening. However the showers move back it
toward morning. The showers are a result of another northern
stream shortwave interacting low to mid level warm advection that
develops as the surface high moves off to our east. A 40 to 50
knot low level jet develops during the day with it's axis aimed
toward Mount Pleasant by mid afternoon. There is not enough
instability for thunderstorms but we will, nonetheless get rain
showers.

- Brief break Wednesday night into Thursday morning

Once that next northern stream shortwave gets east of us Wednesday
evening we get a break in the showers for around 18 hours (more or
less). Wednesday night, should for the most part be dry, as will
Thursday morning.

- Periods of storms with significant rainfall Thursday to
  Wednesday

This could be a very wet period from midday Friday into the middle
of the following week. A large, blocking, upper low developing
over the mid Pacific, is locked in place through at least the
middle of next week as a series of system merge with it. This
causes a large upper ridge to from down stream of it over western
North America. That in turn deeps a central North America trough
from northern Canada to nearly the Gulf coast. The frontal system
associated with that stalled polar jet on the eastern side of
that trough stays near us from Thursday into the middle of next
week. This means a series of surface waves track along the front
given us periods of showers and thunderstorms from Thursday
afternoon into some point next week. Each one of these waves on
the front could bring 1 to 3 inches of rain into our area. If this
really keeps happening for nearly a week, with could become a
real flood threat.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 222 PM EDT Tue Jun 22 2021

Showers and a few thunderstorms with small hail will continue to
move through mid-Michigan this afternoon. Cloud bases are
generally VFR but a heavier downpour may create temporary IFR
visibility, though the probability of this is low at any
particular location. Winds gusting from the west today will go
light and variable around sunset then trend more from the south-
southeast early in the morning. Rain showers from mid-level
moisture streaming in Wednesday morning are expected, with a
trend toward MVFR ceilings near and north of MKG, GRR, and LAN.

&&

.MARINE...
Issued at 330 PM EDT Tue Jun 22 2021

The developing southwest flow on the west side of the departing
surface high results in strong southwest winds starting tomorrow
and continuing into Thursday. We have issued a beach hazard
statement and small craft advisory from tomorrow into Thursday as
a result.
