Synopsis
Issued at 242 am edt Mon mar 18 2019
- no significant precip this week and seasonal temperatures

Discussion (today through next Sunday)
issued at 242 am edt Mon mar 18 2019
not much to write about this week with only a couple chances for
fairly light precipitation. We expect floodwaters to continue to
recede through the period.

There should be some diurnally driven snow showers this afternoon
mostly across eastern zones as lapse rates are still steep enough
to allow enhanced CU development there.

The only other chance of precipitation comes late Wednesday into
early Thursday as a clipper dives south from central canada.

Moisture is limited and it appears the best lift will be just east
of the forecast area so any QPF should be light.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 717 am edt Mon mar 18 2019
vfr conditions through Tuesday morning. Snow showers are possible on
Monday afternoon but should not be heavy enough to significantly
lower visibility. Winds will be west AOB 10 knots.

Hydrology
Issued at 313 pm edt Sun mar 17 2019
most rivers have crested and are now falling, but a few larger,
slower-response rivers are near crest now. Minor flooding near river
banks is occuring along several river points. A dry week ahead with
only limited additional snowmelt runoff due to dry air (dewpoints
generally below 32) will allow rivers to slowly recede.

Substantial areal flooding (not near rivers) occurred or is still
occurring in and near newaygo county, though some improvement has
occurred over the past day. Numerous homes have been affected.

Numerous roads are closed, either due to water still over the road
or damage done to the roads. This area was at the unfortunate
intersection of having a majority of their 3 to 5 inches of snowpack
water content melt along with 1 to 2 inches of rainfall on Thursday,
over a frozen ground which increased runoff.

Grr watches warnings advisories
None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
