Area Forecast Discussion
National Weather Service Grand Rapids MI
732 AM EDT Sat Jun 10 2017

LATEST UPDATE...
Aviation

.SYNOPSIS...
Issued at 328 AM EDT Sat Jun 10 2017

Winds will increase today as low pressure deepens across southern
Canada. Some gusts close to 40 mph can be expected by this
afternoon. Warmer and more humid air will arrive for Sunday and
Monday and thunderstorms will possible across central Lower
Michigan. The storms should become widespread on Wednesday as a
cold front moves in.

&&

.SHORT TERM...(Today through Monday)
Issued at 328 AM EDT Sat Jun 10 2017

A couple issues to deal with in the near term. The first is for
winds this afternoon and evening as model soundings show over 30
knots of wind in the mixing layer and even close to 40 knots by
this evening. There could be a few gusts near 45 mph late
afternoon or early evening but it looks marginal enough to hold
off on a wind advisory.

There is also the potential for an MCS to ride across the top of
the upper ridge Sunday into Monday and affect the northern half
of the forecast area. This will have to be watched. Most of the
forecast ensembles keep the action to our north but we have seen
similar cases in the past where convection moves on more southerly
than forecast. At this point we will follow the model blend and
keep the POPS across the northern zones.

.LONG TERM...(Monday night through Friday)
Issued at 328 AM EDT Sat Jun 10 2017

Very warm and humid wx will continue Monday night through midweek
along with gradually increasing potential for some showers and
thunderstorms toward midweek.

A few showers and storms are possible Tuesday with a boundary
potentially draped across our fcst area by then and based on 00Z
medium range guidance trends. However the better chance for
thunderstorms still appears to come Wednesday afternoon through
Wednesday night with a very warm and humid and potentially quite
unstable airmass in place out ahead of the approaching cold front.

High temperatures Tuesday should reach the upper 80's to lower 90's
and middle 80's to near 90 degrees for Wednesday. A 00z medium range
guidance consensus suggests that some showers and storms may linger
into Thursday especially over our eastern fcst area prior to fropa.

It will remain seasonably warm behind the cold front for late in the
week with high temps expected to reach the lower to middle 80's
Thursday and Friday. However a drier airmass will advect in behind
the front beginning late Thursday.

&&

.AVIATION...(For the 12Z TAFS through 12Z Sunday morning)
Issued at 732 AM EDT Sat Jun 10 2017

VFR conditions will continue through tonight. Southwest winds will
be on the increase with gusts over 20 knots by this afternoon and
continuing into this evening. There could be a few gusts over 30
knots by late afternoon and early evening.

&&

.MARINE...
Issued at 328 AM EDT Sat Jun 10 2017

Decided to replace the Gale Warning with a Small Craft Advisory
based on forecast winds remaining below 34 knots as stable layer
should reduce the winds and strongest gradient will remain north
of our marine zones.

&&

.FIRE WEATHER...
Issued at 328 AM EDT Sat Jun 10 2017

Red Flag Warning conditions will be approached this afternoon as
winds pick up with some gusts near 40 mph. Humidity should remain
above 30 percent as somewhat higher dew points arrive despite deep
mixing. Humidity will increase on Sunday.

&&

.HYDROLOGY...
Issued at 1249 PM EDT Fri Jun 9 2017

Scattered showers resulted in very little measurable rainfall last
night. Most reports came in under five-hundredths of an inch.
Additional showers and thunderstorms could develop today, mainly
east of Grand Rapids. Localized, brief periods of heavy rain
could develop, but should not have much of an impact on rivers.

Given recent dry weather and near normal stream flows, flooding
concerns are nil at this point. The weekend continues to look
mainly dry with a storm track focused north of Grand Rapids.
Portions of central Lower Michigan could see rain chances increase
Sunday night. However, the nighttime mode of convection is
relatively hard to capture with exact timing/placement. Any
variability could make a notable difference in resulting
precipitation amounts.
