KSFY Severe Weather Team Forecast
Rainfall Extending Into Monday
10/20/2019 | From KSFY Television Meteorologist Sam GabrielliA low pressure, that is currently in central South Dakota, will march eastward with time. It will continue to strengthen with time as it crosses into the Twin Cities by Monday evening. As a result, a lot of cloud cover and chances for rain and wind will stick around through early this week. Unfortunately, high temperatures will remain below normal as most spots will fall into the low to mid 40s tonight, only recovering into the 40s and low 50s for Monday.
The wind will begin to pick up in intensity tonight out of the southeast. As the low pressure slowly tilts to the east on Monday, more of a northwest wind will develop with this system. Wind gusts tonight through Monday night may reach the 40-45+ mph range! This is something to note if you have travel plans with a high profile vehicle.
The other issue with this storm system is the rain of course. Flash flooding will not be of concern, but most locations will see between 0.25-0.50" of rainfall when this is all said and done. In fact, some isolated tallies of an inch of rain or more is likely in communities across eastern South Dakota and western Minnesota. This is not the best news when it comes to harvest, but we did go about a week without measurable precipitation.
We will dry out and see the bright sunshine by the time Tuesday afternoon rolls around! High temperatures will also slightly warm up, topping 50° in some spots. After Sunday and Monday's storm, the next opportunity for moisture will arrive on Wednesday as a new clipper system will jet in from the northwest. It might bring a light rain/snow mix to northern South Dakota, but most locations will only see rain as its precipitation type.
A much drier pattern will settle in Thursday into Friday as temperatures will start to approach average readings. The final weekend of October may bring some isolated high temperatures in the low 60s, but we are quite a few days out to get the full details.
