Synopsis
Issued at 300 am edt Wed mar 20 2019
- rain showers developing today; a few wet snow flakes may mix in
north of i-96
- fair weather Saturday into Sunday
- a wintry mix of precipitation possible Sunday night and Monday

Discussion (today through next Tuesday)
issued at 300 am edt Wed mar 20 2019
the merging of northern stream and southern stream upper level
disturbances moving in from the west will bring rain showers late
this morning through this afternoon into this evening. Some wet
snow flakes may mix in at times mainly north of i-96. However
this looks like a predominantly rain event and this notion is
supported by latest runs of the hrrr. Even if pcpn briefly
transitions to wet snow at times there would be very little if any
snow accumulation.

A cold front will come through Thursday night and bring a few
light snow showers and flurries. A high pressure ridge will bring
fair wx Saturday into Sunday. Considerable medium range guidance
discrepancies lead to a lower confidence forecast by Sunday night
and Monday. At the moment guidance trends suggest potential for a
wintry mix of pcpn or rain Sunday night into Monday. Fair wx will
then return Tuesday through midweek as high pressure builds in
from the northwest.

Aviation (for the 00z tafs through 00z Wednesday evening)
issued at 1140 pm edt Tue mar 19 2019
vfr conditions will continue overnight before gradually
deteriorating to MVFR mid to late Wednesday morning as low clouds
move in and rain showers develop. Conditions will deteriorate
further to ifr Wednesday afternoon as CIGS continue to lower and
due to patchy fog and rain. Primarily ifr conditions will then
continue through Wednesday evening due to low clouds showers and
fog. A few wet snow flakes may mix in at some of the terminals
Wednesday evening but potential for snow was too low to warrant
inclusion in any of the terminal forecasts at this time.

Hydrology
Issued at 1136 am edt Tue mar 19 2019
the grand and muskegon rivers remain high after the widespread
rainfall and snowmelt last week. Flood warnings remain in effect for
the grand river at comstock park and robinson township, and along
the muskegon river at newaygo and bridgeton. Meanwhile, a flood
advisory remains in effect for newaygo county as frozen ground
continues to limit the ability of the standing water to drain away
from some roads and houses.

Water levels on both the grand and muskegon are expected to slowly
fall over the coming days. A round of rainfall is expected across
the area during the day tomorrow (Wednesday) which looks like it
could drop between 0.25 and 0.50 inches of rain in some locations.

This has the potential to enhance the issues with ponding and
stranded water across newaygo county, but should not result in any
significant additional rises on the bigger rivers.

Grr watches warnings advisories
None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
