Hazy Hot and Humid (July 19-21)

Discussion: When the sun sets like my photo above you know it’s going to be hot the next day. Therefore I expect to see this kind of sunset the next several evenings. The atmospheric setup is pretty straight-forward for this weekend. An upper level ridge is now building for the Mid-Atlantic and NorthEast US. The Bermuda high is cranking. This means hazy, hot and humid at the surface for New Jersey. Please check on your elders and pets and stay as cool and hydrated as possible! The ridge will move out sometime between Monday-Tuesday as an upper-level trough swings in and cools down the surface. It might me stormy and rainy to start next week but we won’t be dealing with the heat wave any longer. I’ll take a closer look at the frontal rain/storm potential on Sunday when I do the Monday-Friday outlook.

Friday (July 19) high temperatures have just about peaked in the low-to-mid 90s for most. Skies took some time for the fog to bake off but are now clearing with relentless humidity. Winds should be light out of the SW. Overnight lows should fail to dip below the mid-70s statewide.

Saturday (July 20) high temperatures should reach well into the 90s statewide. Interior CNJ/SNJ has the best chance to exceed 100. Immediate coastal areas have the best chance to hang in the mid-to-upper 80s once a sea breeze front gets going. Skies should be mostly sunny but hazy hot and humid. Winds should be light out of the W/SW. Overnight lows should again fail to dip below the mid-70s.

Sunday (July 21) high temperatures should again reach well into the 90s with interior CNJ/SNJ having the best shot at reaching 100.  A sea breeze front could keep the immediate coast in the mid-to-upper 80s but not until afternoon/evening hours. Winds should be light out of the W. Overnight lows should fall into the low-to-mid 70s statewide.

An early look at next week indicates the heat and humidity spilling over into Monday. A cold front is then expected to pass in the Monday PM-Tuesday AM period. This should bring relief and knock high temperatures down into the 80s statewide with lows down into the 60s. Let’s talk more about the frontal passage in a few days. Have a great weekend and please be safe! JC
