AREA FORECAST DISCUSSION
National Weather Service Sioux Falls SD
258 PM CDT Fri Apr 3 2020

.SHORT TERM...(This Evening through Sunday Afternoon)
Issued at 253 PM CDT Fri Apr 3 2020

Residual cloud cover from yesterday`s system hanging around across
the region with clearing beginning to work toward the James
River. This, along with CAA, has kept temperatures well below
normal with most struggling to make it out of the 20s.

Surface high pressure builds in overnight and will set up a rather
chilly morning Saturday. Good radiational cooling will push lows
into the teens for most.

Broad upper level ridging will keep the weekend fairly quiet with
temperatures moderating into the mid 40s to mid 50s for Saturday and
mid 50s to mid 60s for Sunday. If we can stay on the lower end of
the spectrum as far as cloud cover, temperatures could be even a
shade higher than forecast. Precipitation should be minimal,
although a subtle mid level disturbance and push of mid level warm
advection could bring a small chance Sunday night.

.LONG TERM...(Sunday Evening through Friday)
Issued at 253 PM CDT Fri Apr 3 2020

This trend continues into early next week as well with temperatures
continue to push upwards. High temperatures in the 60s and 70s are
expected for Monday and Tuesday and 850 mb temps sit in the 90th
percentile of climatology. Will continue to advertise low end
precipitation chances with guidance flagging decent instability,
although still quite a bit of doubt that this will be utilized or
even accessible.

Cold front works though for the second half of Tuesday and will send
temperatures for the Wednesday onward back into the 50s to mid 60s.
Chances for significant precipitation again appear low as our region
is stuck in between a closed low digging into the desert SW with a
northern stream trough running along the Canadian border. At this
point, the main impacts from these systems look to avoid our region
but certainly time for this to change.

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1209 PM CDT Fri Apr 3 2020

Precipitation has largely exited our area although a few flurries
remain possible into the afternoon. MVFR ceilings will gradually
clear from west to east through the afternoon and evening.
Breezy northwest winds will also decrease by evening with clear
skies and light winds overnight.
