SHORT TERM. (Today and Tonight) Issued at 401 AM CST Thu Dec 5 2019
Shallow ground fog will continue through mid-morning, as winds remain very light and clear skies allow for continued radiational cooling. Temperatures below freezing and a very shallow moisture layer have limited the extent of fog, with the Buffalo Ridge in southwest Minnesota being the location most likely to see continued areas of fog through sunrise.
High temperatures will again be mild today ahead of a cold front which moves through later tonight. The pressure gradient will increase throughout the day, with winds shifting to northwesterly and becoming breezy this evening, gusting 25 to 35 mph. The parent weather system which brings this cold front through will be very moisture-starved, so no precipitation is expected. Overnight low temperatures will be notably colder than in previous nights despite some cloud cover with single digit readings likely in southwest Minnesota.
LONG TERM. (Friday through Wednesday) Issued at 401 AM CST Thu Dec 5 2019
The Canadian surface high over the region on Friday will keep temperatures below freezing for most. The quiet northwest flow pattern that the area has been under the past several days will begin to change subtly this weekend as the flow aloft becomes more westerly. Near the surface, winds become southerly on Saturday on the back side of the high pressure heading off to the east. This will allow for a couple more days of very mild temperatures region- wide before a big change comes Sunday night into Monday.
An amplified ridge over West Coast will help force a northerly jet stream over the Rockies on Sunday night. A well-defined shortwave on the nose of this jet will bring a round of widespread light snow to the Northern Plains Sunday night into Monday morning. Given the cold nature of the air mass in place when this shortwave moves through, high SLRs are likely, which would result in fluffier and more blowable snow than with past systems this winter. Brisk north winds gusting 25 to 35 mph on Monday afternoon may be enough to loft this snow, causing some blowing and drifting issues for those traveling. Temperature-wise, Monday will mark the beginning of severals day with well below average temperatures. Reinforcing shots of cold air are brought southward as shortwaves move along the western side of a deep longwave trough over the Great Lakes. Single digit highs are possible Tuesday, which currently looks to be the coldest day of the next seven. Overnight temperatures in the negative single digits will be good reason to dress warmly. There is low confidence on when warmer air may return, with models diverging notably in how quickly they bring a return to westerly flow aloft: varying from next Thursday to next Sunday.
AVIATION. (For the 18Z TAFS through 18Z Friday afternoon) Issued at 1115 AM CST Thu Dec 5 2019
Low clouds/stratus over North Dakota and northern South Dakota will continue to move southeast into the region this afternoon. This will result in MVFR to IFR ceilings at all terminals through late night. Conditions improve with VFR ceilings through the end of the period.
Light west winds shift to the north-northwest with gusts up to 20 knots this afternoon.

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.

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.
