Summer heat returns to Valley

Hot thermometer             East-central and south-central Minnesota, including the St. Croix Valley, is under a heat advisory from noon to 8 p.m. today with highs expected in the upper 90s and heat indices topping 100 degrees.

Morning clouds are forecast to give way to partly sunny afternoon skies as a warm front lifting north brings hot, humid conditions to the region, according to the National Weather Service office in Chanhassen.

That warm front is forecast to bring with it an afternoon high near 97, and when combined with the humidity, heat indices near 104, said NWS weather forecasters.

The NWS advisory warns that today’s forecast hot, humid conditions increase the risk of heat-related stress and illness, especially for young children and the elderly, persons without air conditioning and people participating in strenuous outdoor activities.

The NWS recommends people wear light, loose-fitting clothing if possible, stay out of the sun, stay in shaded or air conditioned areas and drink plenty of fluids.
The good news is the extreme heat will not last long, NWS meteorologists said.

“The hot and humid air mass will be short-lived as a cold front moves across the area tonight. Expect cooler and drier conditions for the entire region Tuesday,” said an NWS statement.

After a hot afternoon, there is a 40 percent chance of late night and early morning showers and thunderstorms in the region with lows in the upper 60s and west-northwest winds 10 to 15 mph.

Showers and thunderstorms linger into Tuesday morning before skies turn partly sunny. It will be noticeably cooler, with highs near 82 and light west winds.

The rest of the week sees mainly sunny skies, with highs ranging from the middle 80s Wednesday to the lower 70s and upper 60s Thursday and Friday. Lows are forecast in the lower 60s Wednesday morning to the middle 40s Thursday night into Friday morning.
