Area Forecast Discussion National Weather Service Grand Rapids MI 258 PM EST Sun Jan 26 2020

LATEST UPDATE . Synopsis/Discussion/Marine

SYNOPSIS. Issued at 258 PM EST Sun Jan 26 2020

Fairly quiet weather pattern this week with just occasional chances for light snow showers or freezing drizzle.

DISCUSSION. (This evening through next Sunday) Issued at 258 PM EST Sun Jan 26 2020

Colder and drier air slowly filters in tonight and Monday with some lake enhanced light snow showers this evening as sfc trough pushes through. The DGZ dries out after midnight but any precip should be pretty much over by then.

The next chance for any precip is Monday night into Tuesday when some light snow showers or freezing drizzle is possible as another weak shortwave trough comes across Lower Michigan in fairly dry northwest flow.

Model consistency continues to be poor for the weekend with large ensemble spread in how a southern stream low ejects from the southwest CONUS and whether it phases with the northern stream soon enough to affect the Great Lakes. At this point it looks like it will not but the northern stream shortwave trough could be vigorous enough to bring some snow Friday night into Saturday.

AVIATION. (For the 18Z TAFS through 18Z Monday afternoon) Issued at 1247 PM EST Sun Jan 26 2020

Conditions may be improving this afternoon as drier air moves in from the northwest. MVFR conditions should slowly replace IFR from west to east across Lower Michigan by late afternoon. Ceilings are expected to lower blo 1000 feet again tonight. Winds will be west to northwest around 10 knots through Monday morning.

MARINE. Issued at 258 PM EST Sun Jan 26 2020

Small craft advisory is canceled as winds and waves are forecast to remain below criteria. Fairly tranquil conditions will continue through the week.

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.
