Synopsis
Issued at 312 am edt Fri aug 23 2019
- comfortable for the next few days
- next chance of rain: Monday-Tuesday

Discussion (today through next Thursday)
issued at 312 am edt Fri aug 23 2019
high pressure over the great lakes will continue to produce very
comfortable late summer weather through Sunday. As the high moves
east a trough over the ohio valley will help a sfc low move north
toward michigan. Models show this trough as negatively tilted which
suggests that it may be a decent rain producer. Indeed, precipitable
water values climb to 2 inches Monday afternoon as the LLJ noses
into the state. We have fairly high pops late Monday for this.

After Monday, chances for rain aren't zero, but they aren't that
high either. A persistent upper low over western ontario will see
several minor waves push across the state, but the best dynamics
stay north of the cwa.

Highs will be mainly in the 70s through the period. Other than
Monday night, lows will mainly be in the 50s.

Aviation (for the 12z tafs through 12z Saturday morning)
issued at 715 am edt Fri aug 23 2019
vfr conditions will continue through Saturday. Winds will be
north to northeast at 5 to 10 knots.

Marine
Issued at 312 am edt Fri aug 23 2019
north wind 5 to 15 knots will result in 1-3 foot waves
today 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.
