LATEST UPDATE . Synopsis/Discussion/Marine/Hydro

SYNOPSIS. Issued at 252 PM EDT Sun Mar 29 2020

- Wind will decrease tonight

- Warming trend through the week

DISCUSSION. (This evening through next Sunday) Issued at 252 PM EDT Sun Mar 29 2020

-- Wind will decrease tonight --

A deep upper low over eastern Wisconsin will move northeast across Ontario tonight. Although clouds and showers will remain for much of the night, the wind will subside this evening but still be gusty. It's possible tonight that there may be some brief periods of wet snow mixing in with the showers, but no accumulation is expected.

As the upper low moves east, another short wave will move east across the Tennessee valley and the combination of the two will likely keep clouds over the cwa through Wednesday.

The next chance of rain comes Thursday night as the next cold front approaches.

-- Warming trend through the week --

As the upper low moves away from the Great Lakes, heights will rise and correspondingly will temperatures. Monday will be the coldest day with highs around 40, but then temperatures will gradually climb back to the upper 50s by Friday.

AVIATION. (For the 18Z TAFS through 18Z Monday afternoon) Issued at 142 PM EDT Sun Mar 29 2020

A deep upper low continues moving across the Great Lakes. Strong winds will decrease tonight but remain gusty. Look for MVFR cigs throughout much of the period with a few hours of IFR possible during the overnight period.

MARINE. Issued at 252 PM EDT Sun Mar 29 2020

Gales continue to be felt along the lake shore this afternoon. The wind will decrease below gale force late this evening, but remain gusty throughout the night. The gale warning remains in effect until 11 PM south of Pentwater. A Small Craft Advisory remains in effect until 11 PM from Pentwater to Manistee. The wind and waves will remain hazardous for small craft throughout the night and a Small Craft Advisory will be needed for all nearshore zones after the Gale Warning expires.

HYDROLOGY. Issued at 252 PM EDT Sun Mar 29 2020

One to two inches of rain fell over southern Michigan during the last couple of days and that has pushed rivers higher. Only one is in flood stage . the Portage River at Vicksburg, and it should fall below flood stage Monday.

The other rivers in southwest Lower Michigan will remain high this week, but crest below flood stage. After tonight's showers end, much of the upcoming week will be dry which will help river levels recede.

GRR WATCHES/WARNINGS/ADVISORIES. MI . Wind Advisory until 8 PM EDT this evening for MIZ043>046-050>052- 056>059-064>067-071>074.

Lakeshore Flood Advisory until 11 PM EDT this evening for MIZ043- 050-056-064-071.

LM . Small Craft Advisory until 11 PM EDT this evening for LMZ849.

Please verify all results. 5) Weather information is from numerous 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.
