AREA FORECAST DISCUSSION National Weather Service Sioux Falls SD 509 AM CST Mon Dec 16 2019

SHORT TERM. (Today and Tonight) Issued at 337 AM CST Mon Dec 16 2019

Very quiet forecast from the next seven days with dry forecast expected. Patches of stratus is expected to shift south and east throughout the day today leading to partial clearing, but weak flow and snow cover should limit mixing. Have forecast highs mainly in the 20s today.

Weak west to east winds remain tonight. Clouds could hang tough east of I-29, while better clearing develops across South Dakota overnight. Lows will generally be in the teens.

LONG TERM. (Tuesday through Sunday) Issued at 337 AM CST Mon Dec 16 2019

West to northwest flow aloft remains through mid week, but with the jet positioned well to the south of the forecast area, will be a struggle to warm substantially. Have nudged temperatures up a bit closer to mean amongst the various model solutions, as the national blend has been erring on the cool side of things as of late. Weak cool front works through the area Tuesday afternoon with the crux of the cooling focused to the east across the upper Midwest. Potential for a cool night across the area on Tuesday night, however, models are suggesting a fair amount of high clouds across the area Tuesday night limiting cooling potential.

Northern branch of the upper level jet tries to reestablish across the Northern Plains, mainly north of the forecast area. A weak and very moisture starved trough works through the region Thursday night into Friday morning, otherwise, upper level ridging should lead to continued dry conditions. With low level flow out of the south or west, expect temperatures to return to at or above normal levels. Potential for fog with melting snow cover late in the week, but will work on timing as time draws near.

AVIATION. (For the 12Z TAFS through 12Z Tuesday morning) Issued at 505 AM CST Mon Dec 16 2019

Very difficult forecast today. MVFR ceilings slowly drifting east across east central SD into southwest MN. IFR and occasional LIFR conditions in northeast NE and northwest IA have been very slowly drifting north. More than likely once the sun comes up the IFR and LIFR conditions will dissipate and shift south. What happens with the MVFR ceilings is a tougher call. Models really struggling dealing with this low level cloud cover. It seems like there are some hints that this MVFR cloud cover will dissipate gradually by late morning into the afternoon, but once the sun sets it will likely redevelop again.

FSD WATCHES/WARNINGS/ADVISORIES. SD . NONE. MN . NONE. IA . NONE. NE . NONE.

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.
