A very stormy start to the week is on the way with showers, thunderstorms and flooding expected through Wednesday. A cool and unsettled pattern will take hold for the second half of the week and next weekend putting the streak of excellent weather conditions for the weekends in jeopardy.
Monday through Tuesday, a cold front will slowly approach the Philadelphia and New York City metropolitan areas with showers and thunderstorms expected. The strongest thunderstorms will be capable of wind gusts over 60 mph, frequent lightning, heavy downpours, hail, and even an extremely isolated tornado. The strongest thunderstorms are expected Monday afternoon, but thunderstorms will remain strong through Tuesday. Due to the thunderstorms capable of producing very heavy downpours, flash flooding and urban flooding will be a high risk. Visibility in and around the thunderstorms will also be poor. In addition to the thunderstorms, low clouds and areas of fog can be expected. Winds will be from the southwest at 5 to 15 mph. Temperatures Monday afternoon will rise into the lower to mid 80's along the coast and mid to upper 80's throughout the rest of the region. Low temperatures tonight will fall into the lower to mid 70's. High temperatures Tuesday will range from the lower to mid 80's along the coast and mid to upper 80's throughout the rest of the region.
