Marine Weather and Tides
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it.
8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue.
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

UPDATE. (Issued 847 PM CST Sat Nov 28 2020) No changes to the forecast. Quiet conditions will prevail tonight. Expect a few wind gusts to 20 mph this evening over far southeast Wisconsin as a 850 wind max moves across southern Lake Michigan.
SHORT TERM. (Issued 227 PM CST Sat Nov 28 2020)
Tonight through Sunday night:
Quiet weather continues today and tonight as influence from surface high skirting to our south continues across the Ohio River Valley. Looking at overnight lows to fall into low 30s to upper 20s with a few high clouds.
Meanwhile, a mid-level shortwave trough begins to works its way across the southern Canadian Plains overnight. This will bring a surface low into the Lake Superior region early Sunday morning, which will drag a cold front across central and southern WI Sunday morning into the afternoon. This will bring some more clouds with it, but given the lack of moisture in model soundings, it will mainly be dry. Otherwise, expect breezy winds to develop and shift to the west then northwesterly behind the front. This will usher in colder temps with daytime temps falling from around 40 degrees into the 30s by the late afternoon and overnight lows dipping into the 20s.
LONG TERM. (Issued 227 PM CST Sat Nov 28 2020)
Monday through Saturday:
Dry and colder conditions are expected to continue into early next week as Sunday's shortwave trough merges with another mid- level wave coming up from the Southern Plains/Mississippi River Valley. As these systems phase to our east, they are progged to lift up the Mid- Atlantic region Monday. This will bring a potent surface low into the Northeast as well. Although the northeast storm system will remain well to our east, southern WI will be on the back edge of this system and will likely see breezy to gusty northerly winds continue through Monday given the sub-990mb strength and the tighter pressure gradient. Breezy winds will briefly come down Monday night into Tuesday as the system meanders over the Northeast.
Meanwhile, another shortwave trough will dig across the Plains Tuesday and bring a weaker low across the region. The GFS and ECMWF vary on how they handle this secondary/weaker low, where the GFS brings it across the Midwest and eventually merging with the Northeast system, while ECMWF works the low southward across the Plains. Nevertheless, southern WI will likely only see an increased pressure gradient once again and breezy conditions without any precip from this system. However, models agree in a southward shift of the mid-level shortwave trough before cutting off over the Southern Plains, which models then hint at this system lifting northeastward into next weekend.Otherwise, high pressure looks to build in for the later half of the week with slightly warmer temps and dry conditions.
AVIATION. (Issued 847 PM CST Sat Nov 28 2020)
Expect a few wind gusts to 20 knots this evening over far southeast Wisconsin. Otherwise, light southwest winds will prevail into late Sunday morning. Then a cold front will bring gusty northwest winds midday Sunday through Sunday night. Cloud bases will be scattered to broken around 3-5kft. A period of MVFR is possible late Sunday morning, but didn't have the confidence to include in TAFs.
MARINE. (Issued 227 PM CST Sat Nov 28 2020)
Breezy southwesterly winds will gradually come down through the evening, but a few gusts nearing small craft levels will be possible. Then expect winds to increase and shift to west then northwest behind Sunday morning/afternoon's cold front. Strong pressure gradient will develop on the backside of the low that will lift across the Mid-Atlantic into the Northeast and result in stronger winds later Tuesday into Monday. Will likely need a small craft advisory later Sunday evening into Monday, while Gale conditions are expected over the open waters. As the Northeast systems meanders around the region through Tuesday, may see another round of gales across the northern open waters Tuesday night into Wednesday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
