Discussion              

While high pressure shifts off the coast today, it’ll remain close enough to generate another decent day in the Mid-Atlantic region with afternoon high temperatures here well up in the 70’s. A strong cold front will approach the area later tomorrow and there will be an increasing chance of showers as we end the work week. The strong cold front should pass through the region on Saturday and winds will pick up noticeably at night with the influx of the coldest air mass of the fall season so far. Winds will remain an important factor on Sunday as the overall pressure gradient field tightens across the northeastern states as Tropical Storm Philippe merges with this incoming upper-level trough system. Temperatures on Sunday are liable to be confined to near 60 degrees for 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.
