AREA FORECAST DISCUSSION
National Weather Service Sioux Falls SD
1053 PM CDT Mon May 27 2019

.SHORT TERM...(This Evening through Tuesday)
Issued at 328 PM CDT Mon May 27 2019

Potent upper level low that brought areas of heavy rainfall last
night and earlier this morning continues to move east into the
Great Lakes region with broad subsidence in its wake. This recent
rainfall has already started to cause havoc on area rivers with
pronounced rises underway. River flooding will be something that
will be a concern for the days to come.

Could see a few lingering sprinkles out of the remaining cloud cover
but otherwise it will likely be later tonight and early Tuesday
before the next better chance of measurable rainfall. The next
impulse should spark an additional round of showers and
thunderstorms across Nebraska which will move east/northeast with a
few of the high res models clipping our areas south of I-90 with
rain by the early morning and daybreak hours. Severe threat
appears fairly minimal but there is a few hundred joules of
elevated CAPE across our far south to prompt SPC to leave a
marginal risk for severe weather.

The main closed upper low approaches the region later Tuesday into
Tuesday night and will lead to a much better threat of widespread
rainfall across the region. Latest guidance continues to bury the
surface boundary to the south of our area and thus would expect the
main severe threat to remain well south of our area as well. With
that said, there is enough elevated instability and deep layer shear
that the slight/marginal risk over our southeastern half appears to
capture the severe threat adequately. Probably of bigger concern
with the antecedent soggy conditions is the potential for additional
rainfall. Surface low track is still a bit uncertain but there looks
to be two potential areas of focus for the higher rainfall amounts
with one across our northwest quadrant and then potentially across a
few of our NW Iowa counties depending on where convection develops.
As with any convectively influenced QPF, rain amounts are tough to
pin down but a broad average of 0.5 to 1.0 inch looks good with
likely some locations picking up an additional inch plus.
Obviously this will be something to monitor over the next 24
hours, especially across our more sensitive areas. WPC has
highlighted our area in a marginal risk for excessive rainfall.

.LONG TERM...(Tuesday Night through Monday)
Issued at 328 PM CDT Mon May 27 2019

Upper level low is slow to meander across our region with lingering
rain chances Wednesday, perhaps even into Thursday. Beyond that, we
get stuck in between the northern and southern stream jets with no
significant systems expected. Various models still have an
occasional weak disturbance but thankfully the threat for additional
impactful rainfall looks low. Temperatures look to start off in the
60s for highs for the middle of the week before rising back into the
70s to near 80 by late week into the weekend.

.AVIATION...(For the 06Z TAFS through 06Z Tuesday night)
Issued at 1050 PM CDT Mon May 27 2019

Mid-level cloud decks are expected to continue through the night.
Locations south of I-90 including KSUX will likely see a couple
hours of showers and a few weak thunderstorms move through during
the early AM hours Tuesday. Winds will be light overall
throughout the next 24 hours, but could be breezy gusting to 30 kt
in the immediate vicinity of overnight showers. Morning fog looks
unlikely given persistent light winds and abundant cloud cover.
Showers and thunderstorms return Tuesday evening.
