Unsettled Conditions Continue (Aug 31-Sept 3)

Discussion: High pressure in the W Atlantic continues to pump the E US ridge. Until this ridge breaks down, we won’t see any kind of relief from the humidity. We have a cold front slowly sinking over NJ for Friday and Saturday but by Sunday we’re back to the status quo as the frontal boundary returns northward. High pressure in SE Canada will be whipping up an onshore flow for Friday and Saturday. This should make both of those days cooler and cloudier but still with noticeable humidity. By Sunday the flow should switch from onshore to southerly as the SE Canadian high drifts S towards New Jersey’s latitude (well offshore). Sunday and Monday look warmer with S/SW flow. As far as rain and outdoor plans go, Friday looks the wettest. Saturday, Sunday and Monday will likely feature plenty of rain-free time. Just know that a random pop-up shower/downpour or thunderstorm is possible at any time. Again, this is the very definition of unsettled. We are not looking at an all-day washout on any given day this holiday weekend however.

Friday (Aug 31) high temperatures should reach the mid-to-upper 70s. Perhaps some areas in SNJ reach 80. Skies should be damp-feeling and mostly cloudy with showers and thunderstorms possible. Winds should be light out of the E. Overnight lows should fall into the 60s for most. SENJ coastal areas could hang in the lower-70s due to marine influence. Watch out for overnight fog.

Saturday (Sept 1) high temperatures should reach the upper-70s/lower-80s for most. Skies should be partly-to-mostly cloudy with a damp feel. Random Isolated showers and thunderstorms are possible at any time. Winds should remain light out of the E. Overnight lows should range from mid-60s to lower-70s NNJ to SNJ.

Sunday (Sept 2) high temperatures should reach the low-to-mid 80s for most. Skies should be partly sunny for most. NNJ could see more cloud coverage than SNJ. Expect humidity to persist with PM isolated showers and thunderstorms possible. Winds should be light and change from SE to SW throughout the day. Overnight lows should fall into the upper-60s/lower-70s for most.

Monday (Sept 3) high temperatures should reach into the 80s for most. I wouldn’t be surprised to see interior CNJ/SNJ flirt with 90. Skies should be partly sunny with isolated showers and thunderstorms possible. Most should luck out. Some could find themselves under a random brief downpour with rumbles. Winds should be light out of the SW. Overnight lows should fall into the upper-60s/lower-70s for most.

An early look at next week indicates more warm, humid and unsettled conditions. Unfortunately this pattern could last through possibly the first half of September. I’ll have a September discussion article in a few days which will discuss. For now have a great weekend and please be safe! JC
