Another week of dodging showers and thunderstorms can be expected for the Garden State as a series of disturbances from the Pacific race across the country to die as they cross over New Jersey. A powerful upper level low over the Canadian Maritime will block up the pattern which will lead to cold fronts and areas of low pressure to slow and then weaken over New Jersey. As a result, showers and weak thunderstorms will be a threat today on through Friday leading to the threat for localized flash flooding and urban flooding.
Today, one such area of low pressure will collapse before even reaching the New Jersey coast with periods of showers and thunderstorms this morning. The thunderstorms will be capable of very heavy downpours, occasional lightning, and wind gusts up to 30 mph. The bulk of the rainfall will ext by 9 AM this morning. Scattered to broken cloud cover can be expected late this morning on through this afternoon with a few isolated to widely scattered showers and thunderstorms expected. Winds will be from the south at 5 to 10 mph. Temperatures will rise into the upper 70's to lower 80's throughout the state for highs.
Tonight, scattered to broken cloud cover is expected with areas of fog possible by morning. The fog will be locally dense with visibility below a mile, especially over southern New Jersey. A few isolated to widely scattered showers and weak thunderstorms are possible towards morning as well. Winds will be from the south at 5 to 10 mph. Temperatures will fall into the mid 60's for lows throughout the state.
Tomorrow on through Friday, waves of weak disturbances will lift northeast from the Tennessee River Valley towards New England. A warm front will attempt to lift through New Jersey into New England in this time period but fail. As a result, variable cloud cover can be expected with a threat for scattered showers and thunderstorms each day. Due to the high level of moisture in the atmosphere, although the thunderstorms are not expected to be severe, they will be capable of very heavy downpours leading to flash flooding, urban flooding, and visibility below a mile at times. Fog will also be a threat in the morning hours. Low temperatures will range from the mid to upper 60's for lows. High temperatures will range from the upper 70's to lower 80's along the immediate coast, lower to mid 80's over northern New Jersey, and mid to upper 80's over southwestern and central New Jersey.
High pressure will build in just in time for the weekend once again with clearing skies and dry conditions. Temperatures will range from the mid to upper 60's for lows and lower to mid 80's for highs.
