Lets break Monday down by hours.
Morning starts off with sunshine and some cloud cover, a nice start to the day with temperatuers in the mid to upper 50s.
By noon more cloud cover should roll through with spotty isolated showers beginning in our northern counties.
As we head towards dinner (and grills are fired up) showers will filter down to the south.
These will still be widely scattered but a few storms will be included with these by the evening.
Tuesday is a shower and storm day, staying scattered through the morning and becoming widespread during the afternoon, I would say most likely around 2-3pm.
Beyond Tuesday night we clear right back up and warm up as well so don't fret the sun going away.
By the end of the week we should be back to the mid to upper 70s with plenty of sunshine.
And just try not to think about the fact Lake Superior still has ice on it, brrrr.
