Summery Conditions (June 29-July 3)

Discussion: An area of low pressure off coastal New England will dominate the pattern through about Thursday of this week. This will provide periods of northerly flow to New Jersey and the Mid-Atlantic US which will not allow record-type heat. We should still get warm though with plenty of humidity due to high PWAT values and dew points failing to dip below the 60s. This should continue the theme of warm, humid and slightly unsettled. No washout days. Plenty of blue sky, sun and friendly clouds…but the chance for pop-up showers and thunderstorms on any day. It looks like we spike to the warmest day of the week on Friday, July 3 before moderating back into just highs in the 80s for the holiday weekend.

Note: Unless specifically mentioned by location (Example: NNJ elevations, SENJ immediate coast, Interior CNJ/SNJ, etc.) assume the following forecasts are statewide for New Jersey. Directions are shortened (N = North, S = South, W/SW = West/SouthWest, etc.).

Monday (June 29) high temperatures should reach the mi-to-upper 80s for most areas. Traditional warmer locations in CNJ/SNJ (away from the ocean) have the best chance to break into the lower-90s. Skies should be mixed with sun and clouds with isolated pop-up showers and thunderstorms around, especially during afternoon/evening hours. Winds should be light out of the W/NW. Overnight lows should range from near-60 to near-70 NNJ to SNJ.

Tuesday (June 30) high temperatures should reach the low-to-mid 80s for most areas. A slight, not major, relief in humidity is likely. Skies should remain mixed with sun and clouds with more pop-up showers and thunderstorms possible mainly during afternoon and evening hours. Winds should be light out of the N/NW. Overnight lows should range from near-60 to near-70 NNJ to SNJ.

Wednesday (July 1) high temperatures should only reach near-80 for most areas. Skies should be mixed with sun and clouds with more chances for isolated pop-ups. Not as warm but still some humidity around. Winds should be light out of the N/NE. Overnight lows should range from near-60 to near-70 NNJ to SNJ.

Thursday (July 2) high temperatures should reach the low-to-mid 80s for most areas. Skies should be mixed with sun and clouds with more chances for isolated pop-ups. Some, not horrendous, humidity is expected to linger around. Winds should be light out of the N/NE. Overnight lows should range from near-60 to near-70 NNJ to SNJ.

Friday (July 3) high temperatures should reach/break 90 for most areas. Perhaps immediate coastal areas hang in the 80s. Skies should be mostly sunny. Winds should become light out of the SW. Overnight lows should range from mid-60s to lower-70s NNJ to SNJ.  

An early look at July 4th weekend indicates highs in the 80s with more of the same. Sun, clouds, pop-up showers and thunderstorms, and lingering elevated humidity. Let’s take a closer look in a few days. Have a great week and please be safe! JC
