A warm front this morning and a powerful cold front this evening will produce showers and strong to isolated severe thunderstorms through this evening. However, high pressure will take hold just in time to produce excellent weather conditions for this weekend before a hot and humid air mass takes hold for next week.
A warm front will lift northward this morning with periods of showers and isolated thunderstorms. The primary threat will be heavy rainfall with localized urban flooding, very wet roadways, and visibility below 2 miles in heavy rain and fog. Once the warm front lifts northward, scattered cloud cover can be expected. Winds will veer from the east to southwest at 5 to 15 mph. Temperatures this afternoon will rise into the lower to mid 80's over much of New Jersey with upper 70's to lower 80's along the immediate coast for highs this afternoon.
A strong cold front will approach this evening with showers and thunderstorms becoming widespread this evening after 5 PM. The strongest thunderstorms will be capable of wind gusts over 50 mph, frequent lightning, hail, and very heavy downpours. Localized flash flooding and urban flooding will be a threat along with visibility falling below 2 miles. Temperatures will fall into the upper 50's to lower 60's for lows by tomorrow morning.
High pressure will be in control tomorrow on through Sunday with clear skies to scattered cloud cover. Winds will be from the northwest at 5 to 15 mph. Temperatures tomorrow will range from the upper 70's to lower 80's for highs. Temperatures on Sunday will range from the mid to upper 50's for lows and lower to mid 80's for highs.
A hazy, hot, and humid air mass will take hold for Monday and remain in place through next Friday with a threat for showers and thunderstorms at any time. The strongest thunderstorms will be capable of wind gusts over 50 mph, very heavy downpours, frequent lightning, hail, and even an isolated tornado. Fog will be a threat each morning and may be locally dense. Low temperatures will range from the mid to upper 60's, possibly lower 70's in urban areas. High temperatures will range from the lower to mid 80's along the immediate coast and mid to upper 80's over the rest of the state with high levels of humidity. Some locations may even touch the lower 90's in the Delaware River Valley and urban areas.
