WEATHER BLOG: Ushering In Cooler Air

#mdwx: Climate normals for BWI-Marshall on Monday are 78F for the max and 58F for the min.

We are on track Monday to top out in the mid 70s. Lows overnight will dip into the lower 50s.

Tuesday will bring an even cooler shot of air with highs forecast to reach into the mid/upper 60s.

It's all thanks to the passage of a cool front and an area of Canadian high pressure ushering in cooler air.

We will have a chilly start to the day Tuesday, but plenty of sunshine will make for a comfortable afternoon.

Dry weather will then continue through the work-week before our next threat for rainfall moves in late Friday into Saturday.
