Aided by nearly 100 percent sunshine Saturday and Sunday, southerly winds will push highs into the 70s today and perhaps even exceed 80° Sunday. However, early September-like readings this weekend will fall to early December levels in just four days.
The first shoe drops Sunday night with a moderate cold frontal passage that will lower temperatures about 20 degrees. However, the other shoe drops with a strong reinforcing cold front later Wednesday that will send temperatures reeling another 20 degrees to near-record lows. High temperatures Thursday may struggle to warm out of the 30s with Friday morning lows expected to fall into the mid to upper 20s. This would mean a 40-degree plunge from Sunday’s highs to those on Thursday, and an overall 50-degree difference between Sunday’s highs and Friday morning’s lows.
Meanwhile, heavy rains and extensive flooding are expected to continue along the mid-Atlantic coast today.
