Steamy in some areas on Sunday; chance of scattered showers/thunderstorms - Minnesota Public Radio News

Was it steamy enough for you on Saturday? I’d say yes to that.

The Saturday afternoon high temp at Minneapolis-St. Paul International Airport was 88 degrees. A few spots in the metro area touched 90. Dewpoints were in the steamy mid and upper 70s for much of the afternoon.

Sunday highs will be in the 80s in the Twin Cities and much of Minnesota and western Wisconsin. Northwestern and north-central Minnesota will have highs in the 70s:

The excessive heat warning in the Twin Cities metro area expires at 8 p.m. Saturday, replaced by a heat advisory for the overnight hours and much of Sunday. The metro area heat advisory will end at 6 p.m. Sunday. Sunday afternoon heat index values could reach 95 degrees in the metro area.

Thunderstorm chances

Areas of showers and thunderstorms are expected in Minnesota and western Wisconsin Saturday evening and overnight Saturday night. Some locations will have downpours at times. The National Weather Service Storm Prediction Center shows a marginal risk of severe weather in Minnesota and western Wisconsin this Saturday evening and overnight Saturday night. Marginal risk means that an isolated severe thunderstorm is possible.

You can hear updated weather information on the MPR network, and you’ll see updated weather info on the MPR News live weather blog.

A few scattered showers and thunderstorms are also possible on Sunday. By Sunday afternoon, the southern half of Minnesota plus western Wisconsin will have the best chance of scattered showers and thunderstorms.

Temperature trends

Twin Cities metro area highs are projected to reach the lower 80s on Monday and Tuesday, followed by mid 80s Wednesday, Thursday and Friday.

Interests elsewhere in the main Hawaiian Islands, and in the Papahanaumokuakea Marine National Monument, should monitor the progress of this system. For storm information specific to your area, please monitor products issued by the National Weather Service office in Honolulu Hawaii. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM HST (2100 UTC), the eye of Hurricane Douglas was located near latitude 19.5 North, longitude 150.1 West. Douglas is moving toward the west-northwest near 18 mph (30 km/h). This motion is expected to continue through the next couple of days, with a slight decrease in forward speed today. On the forecast track, Douglas will be near the main Hawaiian Islands late tonight and will move over parts of the state Sunday and Monday. Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Gradual weakening is expected through the weekend. However, Douglas is still forecast to be near hurricane strength when it nears the islands. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 110 miles (175 km). The estimated minimum central pressure is 984 mb (29.06 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected on Oahu on Sunday and Sunday night and are possible across Maui County and the Big Island late tonight and Sunday. Tropical Storm conditions are expected across Hawaii County and Maui County beginning late tonight or Sunday. Tropical Storm conditions are possible across Kauai County late Sunday. SURF: Large swells generated by Douglas are expected to affect the Hawaiian Islands during the next couple of days, and storm surge of 2 to 4 feet above normal tides is expected near the center of Douglas. The large swells and surge will produce life threatening and potentially destructive surf along exposed shores. RAINFALL: Heavy rainfall associated with Douglas is expected to affect portions of the main Hawaiian Islands from late tonight through Monday. Total rain accumulations of 5 to 10 inches are possible from Maui County westward to Kauai County, with the greatest amounts in elevated terrain. This rain may result in life-threatening flash flooding and land slides, as well as rapid water level rises on small streams. Douglas is expected to produce 2 to 5 inches of rainfall over the northern half of the Big Island.
