1149 pm cst Sun dec 17 2017

Issued at 1141 pm cst Sun dec 17 2017
visibilities continuing to improve across NW mn as mixing and
clouds increase. Metars showing 3 miles or more across the area.

Light snow Monday morning in the devils lake basin will spread to
the ese into the the northern valley and across NW mn for the
afternoon. A quick 1 to 2 inches of accumulation with localized 4
inches remains possible.

Update issued at 954 pm cst Sun dec 17 2017
fog with variable reductions of visibilities continues to spread
across portions of the valley and most of NW mn. Southern edge
lifting out of fm metro area currently. Expected evolution of the
stratus will push it to the northeast as mixing increases thorugh
the overnight. Light snow into the northern valley is on track
for mid morning.

Update issued at 629 pm cst Sun dec 17 2017
fog and low stratus deck the main concern and impact this evening
and overnight. Lowest visibilities so far at crookston metar
showing a half mile. Will continue to monitor its evolution and
coverage. Dense fog advisory a definite possibility this
evening, will see how observations do over the next couple hours.

Short term (this evening through Monday)
issued at 200 pm cst Sun dec 17 2017
concerns will be fog potential tonight and then snow chances on
Monday. 12z guidance in good agreement.

Lots of questions regarding clouds and fog potential for tonight.

Clouds and fog remain this afternoon where sfc dewpoint values
are in the upper 20s low 30s. Latest rap guidance indicates this
low level moisture will remain in place, and advect northward this
evening, placed along and east of the valley. With this thinking
in mind, will go mostly cloudy with fog east of the valley. Not
sure about dense fog potential but will monitor into the evening
hours. Anticipate high clouds overtaking the region by 12z mon.

Warm air advection overnight will make min temp forecast tricky.

Steady temps along with clouds. Areas with no clouds this evening
will likely see a quick temperature drop before steadying and
possibly slowly rising. How far these temps fall is uncertain.

Left exit region of a strong upper level jet brings forcing and
snow chances to the northern half of the region on Monday.

Increase these snow chances based on the latest guidance. Most
guidance also indicating weak MUCAPE (up to 50 j kg). Given the
forcing along with the potential for weak instability, convective
type snow showers could lead to a quick 2-4 inches on Monday. Main
message is for widespread snowfall totals of 1-2 inches with
localized snowfall up to 4 inches possible.

Long term (Tuesday through Sunday)
issued at 200 pm cst Sun dec 17 2017
a sfc ridge builds into the area on Tuesday with NW flow aloft
becoming more zonal by Wednesday. This will allow an abundance of
pacific moisture to move across the northern rockies and into the
northern tier as sfc low pressure develops lee of the rockies and
moves across the plains. Models continue to show a band of snow
across the CWA Wed aftn... For the best chance of widespread snowfall
accumulations in the long term period. Models are showing
significant snowfall accumulation in the cascades northern rockies
so QPF amounts still in question as well as track of sfc features,
but do think one to three inch accumulations across at least eastern
nd is possible. QPF amounts and calculated snow fall accumulations
did come in a bit lower today which makes sense with what is
expected in the pac nw. Beyond wed, low chances of snow continuing
across the far south into Friday but main feature is a push of cold
air that brings christmas eve highs possibly into the single digits
below zero across the northern two thirds of the cwa. Adjusted
temps with a 50 50 superblend consall solution for thu-sun, however
coldest temps will be dependent on cloud cover, winds, and where
exactly the freshest snowfall sets up mid week.

Aviation (for the 06z tafs through 06z Monday night)
issued at 1141 pm cst Sun dec 17 2017
ifr at bji and tvf expected to improve overnight with stratus deck
eroding from the south and west. Light snow to impact all but the
far TAF Monday with some MVFR CIGS or vsbys.

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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 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.
