River Flood Warning 75, NWS Sioux Falls, SD

Area Forecast Discussion
National Weather Service Sioux Falls SD
322 PM CDT Sun Mar 17 2019

.SHORT TERM...(This evening through Monday)
Issued at 308 PM CDT Sun Mar 17 2019

Well needed quiet conditions prevail across the region today with
a batch of mid level clouds working their way along the MO River
this afternoon and more meaningful sunshine to the north. Bubble
of surface high pressure will slowly sag southward overnight to
our west and could bring another round of some patchy fog
development by the early morning hours Monday.

Not much of a change weather-wise for the daytime hours Monday with
a mix of sun and clouds. Afternoon high temperatures look to run in
the mid to upper 30s north of I-90 where deeper snowpack still
exists and low to mid 40s south.

.LONG TERM...(Monday night through Sunday)
Issued at 308 PM CDT Sun Mar 17 2019

Extended portions of the forecast largely characterized by a
building upper level ridge over the western US with northwesterly to
northerly flow over our region. Shortwave sneaks southward in the
flow on Tuesday although is largely moisture starved until it is
south of our forecast area. At this time, don't expect much in the
way of precipitation other than maybe something very light along
the NE/SD border. Amplified upper level ridge drifts overhead by
the middle and later portions of the work week leading to another
period of quiet weather. The next period of concern will be for
the upcoming weekend as a fairly strong upper level low lifts up
in the southwest flow. This will lead to the potential for another
round of rain and thus raised POPs accordingly. Given the
recent/ongoing hydro problems and sensitivity to any additional
rain, will want to keep an eye on the weekend time frame.

As far as temperatures, look for slowly moderating temperatures
thru the week. Afternoon highs generally start off around or below
normal to start the week with widespread 30s and 40s. By the
later half of the work week, more amplified upper level ridging
should provide for near to above normal high temperatures running
in the 40s and 50s, perhaps near 60 across our far south. Bumped
temps up a tad again for Thursday and Friday but kept changes
tempered based on ensemble spread.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1210 PM CDT Sun Mar 17 2019

Area of MVFR ceilings currently over NW IA should continue to
gradually diminish thru the afternoon hours with only very hit or
miss restrictive level ceilings elsewhere. Otherwise, look for
occasional mid and high level ceilings thru the afternoon. Could
see some fog redevelop later tonight and early Monday but kept
mention fairly minimal in the TAFs at this point due to low
confidence in extent.
