Weekend Weather Spotlight: 5-7-21

Two troughs of low pressure will produce rain, storms, and even some snow in parts of the country through the weekend. 

First, a trough will move from the eastern Great Lakes today through the Northeast on Saturday producing scattered showers and a few storms today and tonight in the eastern Great Lakes, Ohio River Valley, and Mid-Atlantic, and then building east through the Northeast on Saturday and Saturday night. Nothing too major is expected with this activity, maybe some heavy downpours and an isolated severe storm can't be ruled out in south-central Virginia and parts of central and eastern NC this evening

The other trough will have bigger impacts on areas from the northern Rockies eastward producing heavy rain, severe storms, and even the possibility of a little snow. This activity will increase in coverage this afternoon and evening in western and central MT and builds east through the overnight into western ND and extending south into western and central SD. This will bring some much-needed precipitation to these regions. Parts of eastern MT and western ND could see snow mix in or a complete changeover to snow for a period of time during the overnight into Saturday morning, and some light snow accumulations will be possible. Further south a severe storm and heavy rain threat develop beginning in northern and central KS Saturday afternoon or evening, and gradually grow into a large thunderstorm complex that will head east through the rest of the weekend moving through the Mid MS River Valley, Ohio River Valley, and into the Mid-Atlantic and southern New England by Sunday evening and overnight. There will be a threat for a few severe storms on Sunday evening mainly as storms develop into a line south and west of the main area of storms through the Southern MS River Valley.
