Several areas of shower and storm activity are expected across parts of the eastern two-thirds of the country in the next few days. Though a few severe storms are possible, nothing widespread is anticipated.
First, a disturbance develops in central MT this afternoon, tracks into ND late tonight, and then into MN on Saturday. Scattered showers and storms will accompany this feature and initially, a few severe storms will be possible in MT this evening and possibly holding some strength as they make it into western ND around or slightly after midnight before weakening into central ND during the overnight.
Next, another disturbance develops in CO and WY this afternoon and tracks east through the weekend mainly in the vicinity of a front that will be draped from southern NE/northern KS to the Mid-Atlantic states. Scattered showers and storms develop in CO and WY by this afternoon and move through the central Plains late this evening into midday Saturday and into the Midwest Saturday night and Sunday.
The same front by Sunday will be draped from KS to Quebec and will continue to be the main trigger for shower and storm activity Sunday/Sunday night from the southern Plains to western NY.
Widely isolated to scattered showers and storms are likely through the weekend across the Southeast as tropical moisture continues to affect this region.
Finally, ongoing showers and storms early today exiting MN and mainly affecting IA, WI, and IL will continue moving southeast throughout the day. Heavy rainfall at times is expected with this activity especially early in central and eastern WI as well as northern IL, then later on through central IL and northern IN.
