UPDATE. For 00Z Aviation discussion below
SHORT TERM. (This evening through Sunday night) Issued at 358 PM CST Sat Dec 14 2019
After a brief pause in the clearing this morning followed by a short round of surprise light snow, clouds accelerated their dissipation trend again this afternoon. However, a mid level cloud deck across the Dakotas is tracking southeast and has already begun reaching west central MN. These clouds will be pivotal in the low temp forecast for tonight. It appears quite likely western and southern MN at a minimum will be affected, but central MN and WI are also in the running. Temperatures are forecast to be coldest in those areas, as cold as -20. However, if the clouds shroud those areas, which is appearing more and more likely to be the case with satellite trends, temperatures will need to be increased several degrees this evening for those areas.
Clouds will continue into Sunday and Sunday night. Highs Sunday will be cold with little advection, but warm air advection will begin Sunday night and result in steady or slowly rising temperatures through the night into the upper single digits or teens.
LONG TERM. (Monday through Saturday) Issued at 358 PM CST Sat Dec 14 2019
A very quiet pattern will persist through the long term with very little or no precip chances through at least next weekend. A lack of moisture and a zonal, to split flow pattern at times, will keep significant systems from forming. Dry short waves will be responsible for temperature swings, most notably Tuesday night where lows may drop below zero again, and then late week as mid level ridging brings temperatures back up to near freezing. Following the early week cold, temperatures going into the latter portion of the month look mild with no impressive cold air intrusions.
AVIATION. (For the 00Z TAFS through 00Z Sunday evening) Issued at 544 PM CST Sat Dec 14 2019
Mid level clouds over the eastern Dakotas will gradually expand into the area overnight, with ceilings gradually lowering throughout the day on Sunday. By the end of the period (00Z Monday), ceilings should lower into the MVFR category at western/northern sites (KAXN, KRWF, KSTC). Northwest winds will become light and variable this evening into Sunday morning, then increase to 6-10 knots from the south by Sunday afternoon.
KMSP . Mid-level clouds will be on the increase Sunday, with ceilings lowering to near-MVFR by the end of the period (Sunday evening).

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.
