SHORT TERM. (Today through Saturday) Issued at 312 AM CST Fri Dec 6 2019
A large area of low clouds covered the Upper Midwest with pockets of clear skies in central and southern Minnesota. A surface ridge was centered across South Dakota this morning. This ridge will move eastward today, shifting the winds from the northwest, to the west/southwest tonight. Although the atmosphere is quite dry above the boundary layer this morning. The question is whether there is enough mixing in the boundary layer to erode the cloud cover this morning, or until winds shift to the southwest, and more cloud cover begins to spread across the Dakotas, and into western Minnesota this afternoon. The best area of mixing and clearing skies will occur in eastern Minnesota, and western Wisconsin. Farther to the west, less mixing and the added cloud cover across the Dakotas will lead to cloudy skies for most of today. Temperatures could be cooler if more cloud cover is expected over the west. Later tonight, the surface ridge will move off to the east. Warmer air will start to move across the Dakotas, and into Minnesota by late tonight, and into Saturday. As models have been too cool lately with highs, or roughly 5 degrees off, so I am increasing temperatures slightly from guidance on Saturday afternoon. At this time, mid to upper 30s are going to be widespread across the southern half of Minnesota, and western Wisconsin. Depending upon the amount of cloud cover initially Saturday morning, temperatures could reach the 40s, especially along the Buffalo Ridge.
LONG TERM. (Saturday night through Thursday) Issued at 312 AM CST Fri Dec 6 2019
There's little in the way of change this morning with the long term forecast, with mild weather continuing into Sunday, followed by an abrupt reminder of what the heart of winter feels like in Minnesota and Wisconsin.
On Sunday night and Monday, the highly advertised Alberta Clipper system arrives. GFS and ECMWF models have been quite consistent and persistent with this feature, so confidence remains high in a measurable snowfall and a potentially messy commute to start the week. Progged QPF amounts remain around 0.25-0.35 inches, which doesn't sound like much, but given anticipated snow ratios of 20:1 we look to have the potential for a solid 3-5" snowfall across central MN/WI, with lesser amounts around 1-2" along the Iowa border. Given both GFS and ECMWF models are showing pressure tracks/moisture/forcing relatively consistent with our climatology of the Alberta Clipper archetype that yields 6"+ at KMSP, would be surprised if we don't see at least Advisory amounts. Some blowing snow will be possible as well with strong cold air advection ensuing, mainly from west central into southern MN.
Models are beginning to narrow in on the extent of Arctic air following the clipper, with -22C to -25C 925-850mb temperatures settling in for Tuesday and Wednesday. This will most likely correspond with highs from -5F to +5F on those days. Several days of sub-zero lows are expected as well (Tue-Thu), with Wednesday most likely the coldest morning. Could get within a couple degrees of record lows if we can clear the clouds out.
AVIATION. (For the 06Z TAFS through 06Z Friday night) Issued at 1041 PM CST Thu Dec 5 2019
Extensive MVFR stratus doesn't seem to be going anywhere, contrary to the model guidance. Since there are virtually no improving trends, will hold onto the stratus well into Friday morning before mixing and scattering out late morning. This is a low confidence forecast, however.
KMSP . Cigs should remain MVFR overnight and into Friday morning. It isn't clear if/when the stratus will scatter out, but it's not appearing likely until at least mid morning.

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.
