August 6, 2011 — 11:25am
Doppler Radar Estimates. NWS Doppler (from MPX/Twin Cities) shows some 3-4" rainfall estimates from near Clarissa to Baxter, as thunderstorms continue to track from west to east along a nearly stationary warm frontal boundary. The NWS has issued a Flood Advisory, here are the details:
THE NATIONAL WEATHER SERVICE IN DULUTH MN HAS ISSUED AN * URBAN AND SMALL STREAM FLOOD ADVISORY FOR... WEST CENTRAL AITKIN COUNTY IN EAST CENTRAL MINNESOTA... CROW WING COUNTY IN EAST CENTRAL MINNESOTA... THIS INCLUDES THE CITY OF BRAINERD... SOUTHERN CASS COUNTY IN NORTH CENTRAL MINNESOTA... * UNTIL 145 PM CDT * AT 945 AM CDT NATIONAL WEATHER SERVICE RADAR INDICATED RAINFALL AMOUNTS OF 1 TO 2 INCHES ACROSS THE BRAINERD LAKES REGION...AND LOCAL SPOTTERS HAVE REPORTED STANDING WATER ON AREA ROADS.

MOVE TO HIGHER GROUND.
Nagging Storms. NWS Doppler radar at 11:20 am shows strong storms from just north of Alexandria to Little Falls, the Brainerd area, east to Aitkin, just grazing the far northern suburbs of the Twin Cities. The chance of storms in the metro will increase by mid/late afternoon as a cool front approaches - a few of the storms may turn severe. Most of central/southern MN is in a "slight risk" of severe storms, according to SPC.

Another round of heavy rain across the southern half of the state and will continue to linger through the first half of the day today. I am intrigued by the stretch of pleasant weather that looks to be settling in over the next several days as a bubble of high pressure slowly drifts over the region.

Sticky sunshine returns Tuesday with dewpoints spiking in the upper 60s and low 70s. This could help spark a few strong to severe storms later with rounds of heavy rain overnight. Some in southern Minnesota could see as much as 1 to 3 inches of rain through early Wednesday. Check the blog for more details. -Todd Nelson
I hope you get out to enjoy one more comfortable day across the region Monday, as 90s and high dew points make a return Tuesday. That'll also come with the potential of strong storms and heavy rain. When will the nice weather come back - and stick around? Click for more! - D.J. Kayser
A faint puff of Canadian air drops temperatures and humidity levels Sunday and Monday. Better sleeping weather. We warm up later in the week but dangerous heat, extended days or weeks above 90 or 100F, stays south of Minnesota into early August. Check the blog for more details. -Todd Nelson
Friday was volatile, waking up to heavy showers and T-storms passing just south of the MSP metro. After a few hours of warm sunshine another band of severe storms mushroomed up north. The pattern is still ripe for a few more T-storms today, but Sunday should be drier with more clouds than sun and temperatures holding in the 70s across much of the state. We warm up a little next week, but the worst of the blast-furnace heat stays south of Minnesota.
