Two areas of low pressure will pass well to the north and well to the south of the Lake, as this ridge axis remains in place across the western Lakes into Monday. The ridge will finally move east of the area Tuesday, allowing a cold front to push southeast across the lake Tuesday night. LMZ080-669-671-673-675-777-779-870-872-874-876-878-210330-

Synopsis
Issued at 220 pm edt Fri apr 20 2018
high pressure will provide clear skies and gradually warmer
temperatures through the weekend. Mild weather this weekend and
beyond with highs in the 60s. Dry weather through Monday, followed
by increasing chances for rain into Wednesday.

Short term (tonight and Sunday)
issued at 220 pm edt Fri apr 20 2018
high pressure will anchor across the ERN lakes this period as srn
stream bowling ball wraps up across ok Sat and into ar sun. Thus
clear skies and light winds will predominate through Sunday.

Long term (Sunday night through Thursday)
issued at 220 pm edt Fri apr 20 2018
potent SRN stream SW will hold south through the tn valley through
tue before lifting out through the mid atlantic Wed ahead of kicker
nrn stream SW disturbance amplifying sharply through the WRN lakes.

This system looks to bring a good chance for rain to the area Wed as
it swings through the oh valley. Subsequent following secondary
disturbance wraps up through the NRN lakes Fri with another round of
rain likely late Thu into early fri. Combination of both of these
vigorous systems will drive another shot of cold air, albeit brief,
into the oh valley for fri. Until then extended spring like
temperatures abound with daily highs in the 60s outside typical lake
shadow northwest zones.

Aviation (for the 18z tafs through 18z Saturday afternoon)
issued at 134 pm edt Fri apr 20 2018
vfr conditions to dominate with light winds. A weakening system to
the west runs into the drier air mass leaving little more than the
mid clouds late Sat am into the afternoon.

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.
