Discussion
Big changes are on the way this weekend with the influx of a much cooler air mass that had its origins up in northern Canada. A strong cold front will pass through the area on Saturday and winds will pick up noticeably by tomorrow night from a northwesterly direction. Winds will remain an important factor on Sunday as the overall pressure gradient field tightens across the northeastern states as the remnants of Tropical Storm Philippe invigorates this incoming upper-level trough system. Temperatures on Sunday are likely to be confined to the upper 50’s for afternoon highs and the stiff NW wind will make it feel even colder than the actual air temperature. Cooler-than-normal weather is likely to persist for much of next week in the Mid-Atlantic region.
