Area Forecast Discussion
National Weather Service Sioux Falls SD
626 AM CDT WED JUL 13 2016

.SHORT TERM...(Today and Tonight)
Issued at 303 AM CDT Wed Jul 13 2016

Shortwave over south central South Dakota and western Nebraska will
continue tracking slowly eastward today, while a frontal boundary
sags southeastward through the forecast area through mid afternoon.
A good amount of elevated instability exists near and ahead of the
front this morning and will potentially become the focus for
scattered thunderstorm activity today. Models begin to fire storms
along the boundary around daybreak through mid morning, mainly south
and east of a Tyndall to Sioux Falls to Windom line. These storms
will shift eastward with the boundary focusing mainly across
northwest Iowa into the mid/late afternoon. Bulk shear values reach
as high as 40 to 50 kt ahead of the front, with MUCAPE values up
around 2500 j/kg on the RAP and GFS, and much higher with the NAM.
Mid level lapse rates are pretty steep, with a very long hodograph,
so if we do manage enough mid level moisture, a few strong to severe
storms will also be possible as early as mid morning. Main threat
will be hail to golf balls and gusts to 65 mph. Tornadic threat is
very low. Highs today will be in the 80s.

Skies will clear behind the front, with mostly clear skies
continuing overnight. winds will be light from the northwest, with
cooler advecting into the region. Lows will reach the mid 50s to
lower 60s.

.LONG TERM...(Thursday through Tuesday)
Issued at 303 AM CDT Wed Jul 13 2016

Cool mid level temperatures and a band of mid level moisture
spreading into southwestern Minnesota and nearby areas by Thursday
afternoon will be timed with a pretty weak short wave to produce
some convection. It should be pretty anemic given the meager CAPE
which should be less than 500 J/kg, and in fact am tempted to go
just with a slight chance of showers, but will leave in isolated
thunder for now. The day will be cooler under a northwesterly low
level flow, with highs in the mid 70s over most of southwest
Minnesota, ranging up to 80 to 85 along the Missouri River.

Late Thursday night and Friday, warming aloft appears to do a slow
start, with an associated increase in moisture and instability.
Keeping a chance of thunderstorms developing slowly from the west
fits with current model projections. The storm threat should
continue to increase into the weekend and peak about Saturday night
with CAPE up to the 2000-3000 J/kg range. Weak and hard to time
waves in the westerly flow should nevertheless provide some lift for
initiation. Surface warming will lag behind the warming aloft, with
Friday being the coolest day, having highs in the 75 to 80 range.

The slow warming after Friday should put highs into the 80s by
Sunday. By then, the developing and capping upper ridge will begin
to make itself felt, and the chance of storms should begin to drop
off. This is a trend that looks to continue Monday and Tuesday, with
Tuesday rain free and up to sizzling 90 plus levels highs,
accompanied by higher dew points and humidity. Tuesday may see
excessive heat by afternoon. If the heat index is not quite there
yet, it will surely be right after the forecast period on Wednesday,
as the midsummer ridge builds stronger over the area.
