You know Summer is back when the three H's of the season make their mark. You knew this was going to happen sooner or later. As high pressure strengthens off the North Carolina coast, temperatures will climb towards the 80's and 90's while humidity increases each day. Of course, with the heat and humidity comes the threat for showers and thunderstorms each day along with fog in the morning. The heat wave won't last long though and will come to a crash end by this weekend.
Today, high pressure off the North Carolina coast will take hold with clear skies to scattered cloud cover. Winds will back to the southwest at 5 to 15 mph. Temperatures will climb into the lower to mid 80's for highs this afternoon with increasing humidity.
Tonight, scattered clouds can be expected with areas of fog developing towards morning. The fog will be locally dense with visibility below 2 miles. Thunderstorms will be a threat, especially over northern New Jersey. The thunderstorms will be capable of wind gusts over 40 mph, heavy downpours, hail, and frequent lightning. Winds will be from the south at 5 to 10 mph. Temperatures will fall into the mid 60's for lows.
Tomorrow on through Thursday; hazy, hot, and humid weather will be in place. Fog, locally dense, will be a threat in morning hours. In the afternoon to late night periods, disturbances will dive from the Great Lakes towards New Jersey with showers and strong to severe thunderstorms. Although severe thunderstorms will be isolated, they will be capable of wind gusts over 50 mph, very heavy downpours, frequent lightning, hail, and even an extremely isolated tornado. The best potential for thunderstorms will be over northern and central New Jersey. Temperatures will range from the upper 60's to lower 70's for lows and upper 80's to lower 90's for highs.
On Friday, a very strong cold front will drive south from southeastern Canada through New Jersey with widespread showers and strong to severe thunderstorms. Low temperatures will range from the mid to upper 60's. High temperatures will range from the mid to upper 80's throughout the state as the heat wave breaks.
High pressure from the Canadian Maritime will take hold for Saturday and Sunday which will mean a fresh, cool, dry air mass will return just in time for the weekend. Temperatures will fall back to the upper 50's to lower 60's for lows and upper 70's to lower 80's for highs.
