Discussion
A major rain event is on the way...low pressure generated some rain in the Mid-Atlantic region last night as we began a transition to a cooler weather pattern, but a much more significant system will affect us on Saturday and Saturday night with as much as 1.50 to 3.00 inches of rain. Last night's system will pull away from the region this morning and high pressure will briefly try to build into the area. Another - and much more impressive - low pressure system will track along a frontal boundary this weekend from the Ohio Valley into southwestern New York State and it is likely to generate heavy rain for much of the I-95 corridor on Saturday and Saturday night. Embedded thunderstorms will also play a role in this unfolding large system; especially, in southern sections of the Mid-Atlantic region. Lingering showers are possible early Sunday and it’ll stay on the cool side of normal, but it'll turn warmer with more sunshine as we begin the new work week.
