KSFY Severe Weather Team Forecast
Above Average Temperatures To Start Off Autumn
9/23/2019 | From KSFY Television Meteorologist Sam GabrielliSome patchy fog is not out of the question in river valleys this morning, otherwise we will remain quiet and crisp. Surface high pressure will take control of our weather, bringing in plenty of sun and high temperatures above average today. Today also marks the first official day of fall! Expect afternoon thermometer readings to enter the upper 70° range for most locations, with those in central South Dakota and along the Missouri River to reach the low 80s.
Our friendly high pressure system will move towards the Ohio River Valley tonight and into Tuesday but will continue to usher in mild temperatures and plenty of sun once again. High temperatures will reach the 80s during the day Tuesday.
Heads up for those of you that live in Sioux Falls and points east! A storm or two may develop along an incoming cold frontal boundary in the evening hours. Any storms that decide to develop may turn strong or severe, thus producing wind gusts up to 60 mph or some isolated large hail. The best opportunity for the storms appears to be over northwest Iowa and for those in southwest Minnesota, where a slight risk of severe weather is issued by the Storm Prediction Center.
Our pattern will quiet down again Wednesday, but a breezy northwest wind will drop high temperatures back below normal. As we progress into the end portion of the week, it appears more and more likely that a storm system will be approaching from the west. Details on rainfall forecast and timeline of the rain is too vague at this point. High temperatures will also bump below normal to end the 7-Day Forecast as well.
