The National Weather Service in Twin Cities/Chanhassen has issued
a Heat Advisory, which is in effect from 1 PM this afternoon to
10 PM CDT Monday. The Excessive Heat Watch is no longer in
* TEMPERATURE...Highs near 90 and dew points in the 70s will make
for heat indices around 95 to 100 degrees for both Sunday and
Monday. Low temperatures tonight will only fall into the mid
70s, providing little relief from the heat.
* IMPACTS...The high heat indices during the day will lead to
increased risk for heat-related illness for those active
outdoors or with limited access to air conditioning.
Take extra precautions...if you work or spend time outside. When
possible...reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when possible
and drink plenty of water.
To reduce risk during outdoor work...the occupational safety and
health administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by heat
should be moved to a cool and shaded location. Heat stroke is an
emergency...call 9 1 1.
Monday highs reach the lower 90s across much of southern and central Minnesota and parts of Wisconsin:
Twin Cities metro area highs are projected to reach the lower 90s Monday, followed by upper 80s Tuesday through Friday.
A few scattered showers and an isolated thunderstorm are possible over eastern Minnesota and western Wisconsin during the early morning hours today. The main event will be later this afternoon and evening, as showers and thunderstorms develop in western Minnesota and spread eastward.
The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential rain pattern Sunday afternoon through Sunday night:
The color chart to the right of the loop refers to the strength of the signal that returns to the radar, not to the amount of rain. It’ll rain in some areas that look dry in the NAM model, but the loop shows the general rain pattern as it develops and spreads southeastward. Check forecast updates.
The Storm Prediction Center of the National Weather Service shows a slight risk of severe weather for much of Minnesota and northwestern Wisconsin Sunday and Sunday night, which means that scattered severe thunderstorms are possible. Here are local details, from the NWS:
