Area Forecast Discussion
National Weather Service Sioux Falls SD
642 PM CDT Thu Apr 19 2018

.SHORT TERM...(This evening through Friday)
Issued at 309 PM CDT Thu Apr 19 2018

A mild and fairly pleasant day across the area, even with
temperatures 15 degrees below normal. Surface high pressure is
gradually shifting east with southeast flow expected to develop
through the night into Friday. This will allow for relatively mild
overnight lows in the 20s with increasing clouds.

The right entrance region of the northern jet and a developing low
pressure over the Rockies will combine to bring a minor chance for
showers to the area on Friday. Low level temperatures will be warm
enough to allow high temperatures to vary from 45 to 55 degrees.

.LONG TERM...(Friday night through Thursday)
Issued at 309 PM CDT Thu Apr 19 2018

Dry and increasingly mild weather is expected Saturday through
Monday as a cut off low pressure slow moves across the Southern
Plains and the northern branch of the jet stream shoots across the
Canadian border. This will allow high to gradually increase from
the 50s into the 60s on Monday. Monday night into Tuesday a fairly
weak system will move through and bring a chance for showers.
Behind this wave mild weather will again build into the area.
