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.

UPDATE. (Issued 931 PM CST Sun Jan 17 2021)
Another round of light snow within cyclonic for se WI but mid level drying will gradually end the snow from west to east into the early morning hours. Up to one half inch will be possible. More flurries are expected afterward and probably through Mon.
SHORT TERM. (Issued 312 PM CST Sun Jan 17 2021)
Tonight and Monday:
Low pressure over Lower Michigan will slowly pull away tonight. Southeast WI is still seeing light snow showers with this low level moisture stuck in cyclonic flow, along with weak low level frontogenesis. Very light snow showers or flurries may linger for portions of southern WI through much of the night until the upper low moves out and drier air can move in.
Cyclonic flow aloft will linger, but overall forcing will be weaker than today. Therefore, we should not see snow, but clouds will likely hang on all day. Given drier air aloft, we could actually see a few holes develop in the cloud cover Monday afternoon, especially near the lakeshore, but don't get your hopes up. High temperatures should be a notch cooler tomorrow than they were today.
LONG TERM. (Issued 312 PM CST Sun Jan 17 2021)
Monday night through Sunday:
We have a chance of less cloud cover Monday night which will allow us to drop into the teens overnight. Anywhere we clear out will have a chance at seeing single digits, especially toward central WI.
Our next shortwave trough and associated surface low in the train of waves will arrive Tuesday afternoon. There is an increasingly more consistent signal of this feature dropping light snow across most the IA/WI/IL corridor Tuesday afternoon and evening.
We can expect a brief warm-up on gusty southwest winds Wednesday in advance of a potent low that will be crossing Ontario Wednesday night into Thursday. Precip should remain north of southern WI with this system. We should remain dry under brisk northwest winds until Saturday morning. There is a chance for accumulating snow for late next weekend.
AVIATION. (Issued 931 PM CST Sun Jan 17 2021)
Vsbys with the light snow over se WI will range from 2-5SM into the early morning hours, then ending. MVFR Cigs will prevail tnt- Mon but areas of VFR Cigs 3.5-4.5 kft will occur at times.
MARINE. (Issued 312 PM CST Sun Jan 17 2021)
Winds will remain steady out of the northwest or west through Tuesday. Low pressure crossing Ontario will drag a cold front through the Upper Great Lakes Wednesday night. Southerly wind gusts ahead of this front may reach gale force Wednesday afternoon and evening for both north and south halves, but probably not the nearshore area of southeast WI. This is a short window for gales, but there is decent agreement amongst model forecasts. Gusty northwest winds are expected for the remainder of the week, although they should remain below gale force.

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 numerous 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.
