Short term (this evening through Tuesday)
issued at 350 pm cdt Mon aug 19 2019
area of stratus across central south dakota highlighting an area of
low level moisture working north ahead of a short wave moving east
along the south dakota nebraska border. With strong 850 hpa warm
air advection ahead of this wave, expect thunderstorms to develop
this evening once warm air is able to work around the elevated mixed
layer around 700 mb. Atmosphere is unstable with steep mid level
lapse rates leading to 2500-3000 j kg of cape. With 0-6 km bulk
shear near 50 knots along the i-90 corridor (with greater shear
values to the north), expect some storms to be severe. With the
freezing level embedded in the steep mid level lapse rates, expect
hail to be a possibility, along with strong damaging winds with a
wealth of dry air aloft. 12z sounding out of top indicated nearly
1.70" of precipitable water, which is near the 90 percent moving
average. Dew points have climbed to near 70 f south of i-90,
indicative of moist airmass working into the region. Training of
storms may lead to very heavy rainfall overnight.

Long term (Tuesday night through Monday)
issued at 350 pm cdt Mon aug 19 2019
more tranquil conditions are expected Tuesday into Wednesday as high
pressure builds into the northern plains. Disturbance moving across
nebraska Tuesday night into Wednesday may lead to some light
rainfall along the south dakota nebraska border.

Flow becomes more active late this week as dirty zonal flow ushers a
series of disturbances in the northern plains. This will result in
potential for unsettled weather for the weekend into the early part
of next week.

Aviation (for the 18z tafs through 18z Tuesday afternoon)
issued at 1230 pm cdt Mon aug 19 2019
MVFR stratus across central south dakota will begin to break up
early this afternoon. Expect cumulus to develop in central south
dakota this afternoon. Isolated storms are possible towards 00z
near the james valley, with the threat spreading east towards the
i-29 corridor in the 4-6 z time frame, and east after 06z. Large
hail and brief wind gusts are possible with convective activity
that develops.

MVFR to ifr stratus can be expected across much of the area
Tuesday morning, with gradually improving conditions towardsVFR
near 18z.

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.
