Twin Cities Weather: Hot, Humid Days Give Way to Stronger Storm Risk Later This Week

Moisture from the Gulf plus monsoonal flow will fuel scattered severe storms capable of damaging winds, hail, heavy downpours.

Overview

  • Hot, humid conditions will persist through Thursday with daytime highs near 90–93°F and heat-index values in the mid-90s, producing uncomfortable afternoons and warm nights.
  • Nighttime conditions will stay muggy with lows around the low 70s, which can reduce overnight cooling and raise heat stress for people without air conditioning.
  • A few isolated thunderstorms are possible north of the metro area in the midweek period, but storm coverage and intensity are expected to increase late Thursday into Friday.
  • Forecasters warn scattered storms Thursday evening into Friday could produce damaging straight-line winds, hail, and heavy downpours that may cause brief flash flooding in localized areas.
  • Periods of heavy rain Friday should cool daytime temperatures into the upper 70s, and the region is forecast to settle to milder, drier conditions with highs in the mid-80s by the weekend with morning fog possible.
