SHORT TERM. (This Evening through Saturday) Issued at 242 PM CST Fri Jan 22 2021

Not many changes to the forecast. Models still very consistent supporting snow potential for late tonight into Saturday night. No real hints that a warning will be needed, just a solid advisory, especially north of I-90.

Broad warm advection will be the main driving force for snowfall production, and that forcing in and around about 800 mb to 700 mb looks like the preferred layer, although lift lower in the atmosphere may also produce some snowfall. While instability driven enhanced frontal forcing is not anticipated some banding will be likely. The better forcing moves into south central SD late tonight and spreads across areas near and especially north of Interstate 90 through the morning. Far southeast SD into northwest IA may see a quick glancing shot of light snow in the morning, then see a break for a few hours before the main wave brings additional cooling and saturation into the area by mid afternoon into the early evening. This short break could reach as far north as Interstate 90 in far eastern SD and southwest MN right around mid day, before filling in again. Nothing in the soundings hints at any concerns for mixed precipitation, so will see pretty much a straight forward snowfall event. There is always a chance for some patchy freezing drizzle when saturation in the ice bearing layer dries out, but not seeing any significant signals. Temperatures should be pretty steady in the 20s through the day.

The mid level wave and lower level warm air advection quickly shift east during the evening with most locations out of the snow between 6 pm to midnight from west to east. Raised lows a touch with some wind and clouds, but still in the teens.

LONG TERM. (Saturday Night through Friday) Issued at 242 PM CST Fri Jan 22 2021

Weak upper level ridging will move through on Sunday which will bring dry and cool conditions. Highs mostly in the 20s, just a touch below normal.

Weak ridging continues Monday into Tuesday as stronger troughing moves through to the south of the area. This will keep colder air in place so temperatures will remain below normal. Highs in the teens to lower 20s both days with lows mostly in the single digits, possibly below zero as well with the fresh snow cover. Tuesday night into Wednesday a weak wave moves through and some light snow will be possible.

Wednesday night into Friday broad and fairly sharp upper level ridging will move into the area as a trough of low pressure digs into the west coast. Much warmer air will surge out ahead of this trough, but will have to keep an eye out for stratus potential as the warm air aloft appears to come flying in before it can get to the surface which might just create a strong inversion and trap low level moisture.

AVIATION. (For the 06Z TAFS through 06Z Saturday night) Issued at 1039 PM CST Fri Jan 22 2021

Light south/southeasterly winds overnight. Light snow will begin to develop over south central SD after 10Z tonight, then spread to the north and east through the day on Saturday, most affecting areas from the Interstate 90 corridor and northward. With that will come lowering ceilings and visibilities. Southeasterly winds will increase a bit during the afternoon, gusting near 20 kts a times, which may result in some blowing snow. Light snow will continue into Saturday evening, diminishing from west to east after 03Z.

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.
