Coming up for air
The Doppler has been colorful lately. Sunday's rude awakening tracked about 800 miles from Pierre, SD all the way to Michigan. When the Doppler timeline looks like this, duck and cover.
Derecho alley?
I wrote more about our latest probable derecho event, and why Minnesota appears to be in the heart of "derecho alley" here.

Monday's storm wave produced another round of severe T-Storms south of the Twin Cities. The metro enjoyed garden variety storms. Another free lawn watering courtesy of Mother Nature.
'Peak severe'
Welcome to the heart of severe weather season in Minnesota. June is the most active month for severe storms around here. Your best chance for a chorus of "tone alerts" from your NOAA Weather Radio or smart phone? The weeks between Memorial Day and the 4th of July.
Most of us catch a break in rainfall and storms overnight. Then we watch the next series of storm waves blossom on Doppler Tuesday.
Tuesday severe risk
The best chance for severe storms? It still looks like Tuesday night across Minnesota. NOAA's Storm Prediction Center paints an enhanced risk over western Minnesota Tuesday nudging the far west metro suburbs. The rest of the Twin Cities, and a zone from Rochester to Brainerd ride the slight risk category.
Tuesday night bow echo?
NOAA's NAM 3 km model continues to insist on a developing squall line that could have bow echo (damaging wind and hail) potential Tuesday evening. The line is likely to form in eastern South Dakota Tuesday afternoon and race across Minnesota Tuesday evening. The most likely time of arrival in the Twin Cities appears to be around or just after midnight.
We'll have to keep an eye out for a few more severe storms Wednesday as the overall pattern shifts east.
Drying out Thursday
Drier and cooler breezes kick in starting Thursday. Thursday and Friday look sunnier. The next low pressure storm races east into Minnesota Friday night into Saturday. Father's Day looks sunnier right now with a cooler breeze.
Cooler breezes
Heat and humidity gradually fade as the week rolls on.
Keep an eye out for storms Tuesday night.
