Synopsis
Issued at 240 am edt Sat aug 24 2019
- comfortable weather continues through the weekend.

- showers storms likely Monday night through Tuesday morning.

Discussion (today through next Friday)
issued at 240 am edt Sat aug 24 2019
a large dome of high pressure over the great lakes will result in
clear skies through Sunday. So another day with highs in the mid 70s
lows around 50 is expected. Late in the weekend, the high will drift
east and more humid weather will return. A sizable upper trough
will move through late Monday ahead of a cold front and give us a
good chance at seeing rain. Locally heavy rainfall appears possible
given precipitable water values around 2 inches. QPF in excess of an
inch is progd for much of the western CWA late Monday into Tuesday.

This looks like mostly a rain event with a few embedded non severe
storms due to limited instability.

After the cold front moves through Tuesday, drier and cooler air
will flow into the CWA and highs will fall back to the lower to mid
70s.

Aviation (for the 12z tafs through 12z Sunday morning)
issued at 718 am edt Sat aug 24 2019
vfr conditions will continue through Sunday. Winds will be east
to northeast at 5 to 10 knots today.

Marine
Issued at 240 am edt Sat aug 24 2019
high pressure over the great lakes will result in 1-2 foot waves and
variable winds around 10 knots today and tonight.

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.
