National Weather Service Grand Rapids MI
509 PM EDT TUE JUL 12 2016
LATEST UPDATE...
Update
.SYNOPSIS...
Issued at 322 PM EDT Tue Jul 12 2016
We'll have a few opportunities for rain during the next 36 hours as
several waves of low pressure move across Lower Michigan. A few of
the storms may become strong to severe late this afternoon and again
Wednesday. Additionally, heavy rain remains a threat in this muggy
atmosphere. Cooler and drier air will move over Lower Michigan late
in the week and the weekend.
&&
.UPDATE...
Issued at 509 PM EDT Tue Jul 12 2016
The storms have formed a nearly solid line with gusty winds so I
used the HRRR 19z run to update the grids to show the progression
of the line eastward through the rest of our CWA. Little question
nearly every place from kalamazoo through harrison will see these
storms this evening. The storms should be out of the area by 8 pm.
&&
.SHORT TERM...(This evening through Thursday night)
Issued at 322 PM EDT Tue Jul 12 2016
Radar is beginning to light up as a trough moves across the cwa.
TSRA have developed west of US-131 and are building south as the
line heads east. The storms are encountering a low shear environment
but an unstable one in which low level lapse rates are around
7.5c/km. This type of sounding will likely result in a few storms
that produce strong winds. In addition, pwats over 2 inches will
help the storms produce heavy rainfall. Storms should exit the cwa
by early evening leading to a generally dry night.
We may see a couple of rounds of showers/storms Wednesday due to
short waves moving through the flow. The first arrives around
sunrise and the second after 18z. Each of those may result in
storms, however the afternoon storms stand the best chance of
becoming severe. SPC slight risk covers almost all of Lower
Michigan. Shear values climb to around 30-40 knots Wednesday and so
hail also becomes a threat in addition to strong winds. An uptick in
the LLJ to around 35 knots late in the day will aid in storm
development too.
The next short wave arrives around 06z Thursday ahead of the cold
front. More storms are possible overnight and then conditions will
quiet down Thursday afternoon and night. It's worth noting that
precipitable water values increase to around 2 inches again
Wednesday...after decreasing tonight...and so a heavy rain threat
will remain in place through Wednesday.
.LONG TERM...(Friday through Tuesday)
Issued at 322 PM EDT Tue Jul 12 2016
Temperatures will be seasonably cool on Friday as heights fall and
northwest flow continues through the weekend. The subtropical ridge
builds north again early next week and mid level warm advection and
moisture return could bring some isolated showers or thunderstorms
as early as Sunday.
Chances for showers and thunderstorms may be increasing by Monday as
any convection that forms at the top of the upper ridge should move
southeast into Lower Michigan. Model ensembles show some support for
an MCS, but at this time range there is a lot of spread/uncertainty
so chance POPs should cover it for now.
&&
.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 145 PM EDT Tue Jul 12 2016
VFR conditions will prevail today, but a line of showers and
thunderstorms could form and bring areas of MVFR and isolated IFR
conditions this afternoon across central Lower Michigan. These
storms will move east into eastern Lower Michigan this evening.
South winds will gust to 20 knots at times into this evening.
&&
.MARINE...
Issued at 322 PM EDT Tue Jul 12 2016
The SCA and beach hazards statement will remain in effect until 9 pm
tonight after which winds and waves will decrease below advisory
criteria. Headlines may be needed again Thursday as a cold front
moves across the lake and winds increase behind it.
&&
.HYDROLOGY...
Issued at 322 PM EDT Tue Jul 12 2016
Localized flooding is possible this afternoon and evening as pulse
thunderstorms develop. Any stronger pulse storm will be capable of
heavy rainfall. With surface dewpoints in the upper 60s to low 70s
and PWATs near 2 inches, high rainfall rates are likely.
