Synopsis
Issued at 223 am edt Sun aug 25 2019
- one more day of fair weather
- showers and a few thunderstorms move in Monday

Discussion (today through next Saturday)
issued at 223 am edt Sun aug 25 2019
sfc high will provide one more day of fair weather and then
moisture begins to return as it moves east tonight and Monday.

Moisture advection and isentropic ascent increases on Monday with
scattered showers breaking out during the morning and increasing
into the afternoon.

A sfc low tracking north of lake superior will bring a trailing
cold front through late Monday night. Thunderstorms are expected
along the front but coverage and strength will be mitigated by
marginal instability during late night passage. Precipitable water
values are approaching 1.9 inches overnight so heavy rain rates
are expected with any deep convection, and any area that sees
training of storms in southerly flow could get some localized
flooding late Monday night into early Tuesday morning.

Another period of fair and cool weather to follow for Wednesday
through Saturday as canadian high pressure returns and persists
across the central great lakes.

Aviation (for the 12z tafs through 12z Monday morning)
issued at 718 am edt Sun aug 25 2019
vfr conditions will continue through tonight. Winds will be east
around 5 to 10 knots.

Marine
Issued at 223 am edt Sun aug 25 2019

build through Monday. A small craft advisory will likely be needed

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
