Key Points – Monday, October 2, 2017:
Synopsis: Good Monday morning! Big weather story in the short-term will be heavy rain and flash flood concerns as a potent disturbance interacts with a frontal boundary tonight bringing very heavy rain and storms to Minnesota and southeast South Dakota overnight. The weather pattern looks to become drier by mid-week as this front shifts well south of the area.
Today’s video (6:48):
Marginal threat for a few stronger storms with wind and hail from late this afternoon through tonight. Heavy rainfall is the biggest threat here.
Below is a future radar animation from the latest hi-res NAM showing the storms ramping up beginning this evening and continuing throughout the overnight hours, mainly from central Minnesota into southeast South Dakota.
Very heavy rains of 2-5″ appears rather likely tonight in the circled area on the map below off the latest hi-res NAM model.
A drier and cool weather pattern sets in mid to late week. We may see another round of rain chances on Friday, especially south. Confidence is lower at this time.
