A beautiful, crisp day on tap. No changes needed at this time.
Northwest winds will continue to decrease today as high pressure builds in. Light winds will then continue through Monday night.

SHORT TERM .
Today through Monday . Forecast Confidence is High . Quiet conditions are expected for today and tomorrow as high pressure sits over the area. Mostly sunny skies will give way to more clouds tonight as a low pressure system passes to the south. The dry air associated with the high pressure is expected to keep precipitation south of the area, but flurries can't be completely ruled out along the state line as 850mb convergence may briefly overcome the dry air. Clouds will linger into Monday, but temperatures will be warmer with highs in the mid 20s to low 30s.
Monday night through Tuesday night . Forecast confidence high.
A large upper low and associated sfc low will track from south central Canada to New England during this period. The sfc low will gradually deepen as it does so. Ahead of this feature, a west to east sfc ridge will shift south across srn WI Mon nt-Tue AM. Modest wly winds will prevail on Tue shifting nwly for Tue nt with a dry cold frontal passage. A cold night, mostly in the single digits, is forecast for Tue nt.
LONG TERM . Wednesday through Saturday . Forecast confidence medium.
Will continue to use the ECMWF and NBM as guidance in the extended fcst. Polar high pressure will arrive for Wed with a cold day expected. Milder temps are then expected the remainder of the week as sly flow and warm advection develops ahead of an approaching shortwave trough from the wrn USA. A weak cold frontal passage will eventually occur on Sat. The airmass may remain dry enough for no precipitation.
AVIATION(06Z TAFS) .
MVFR ceilings are clearing this morning with VFR conditions expected for the remainder of the day. Winds will be from the northwest and decrease through the day becoming light and variable this evening. Clouds will move back in from the south tonight with ceilings around 7,000 to 10,000 feet.
MARINE . Northwest winds will decrease today as high pressure builds in. Light winds will then continue until Tuesday as deepening low pressure system develops over southern Ontario. Winds will increase from the northwest through Tuesday with gusts up to 30 knots Tuesday night into Wednesday morning. A Small Craft Advisory may be needed for the nearshore waters Tuesday night.

I do not sell or share any user data or anything else for that matter. I do not keep site logs longer than I need to to keep bad actors off the site. Basically, I delete them after looking at them. If you are subject to CCPA, Google ads on this site will not be based on your past behavior so you will likely not see an ad for a lawn mower just because you looked for one at a big box website. I do not believe this site is subject to CCPA but I am doing what I can to follow the guidelines anyway.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

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.
