You can not ask for better weather for the end of July with low humidity, seasonably cool temperatures, and clear skies in place. While this excellent weather pattern will continue through the week, the weekend is looking a bit unsettled with the threat for showers and thunderstorms.

High pressure will be in control today on through Friday afternoon with clear skies to scattered cloud cover expected. A few isolated showers are possible in the afternoon over northwestern New Jersey, however these showers will be very rare and associated with weak disturbances dropping south from the Great Lakes. Otherwise, dry and tranquil conditions are expected. Winds will be from the north at 5 to 10 mph through tomorrow afternoon before slowly veering to the southwest by Thursday morning. Temperatures this afternoon will range from the upper 70's to lower 80's for highs. Temperatures tomorrow and Thursday will range from the lower to mid 60's for lows and lower to mid 80's for highs. Temperatures on Friday will warm into the mid to upper 60's for lows and lower to mid 80's for highs.

A series of low pressure systems will lift from the Tennessee River Valley towards New England Saturday on through Monday. New Jersey will be on the warm side of this storm track, leading to more humidity and warmer yet seasonable temperatures. Showers and thunderstorms along with broken to overcast cloud cover can be expected through the period. The thunderstorms will be capable of very heavy downpours, frequent lightning, hail, and damaging wind gusts. Low temperatures will range from the mid to upper 60's through the period. High temperatures will range from the mid to upper 80's.

This warm and muggy period won't have much legs though as a cool Canadian air mass will return for the middle of next week with well below normal temperatures for New Jersey once again.
