The Heat is On (June 18-22)

Discussion: The week begins hazy, hot and humid thanks to departing high pressure and ends more pleasant with another area of high pressure moving in. In the middle of the week we have a weak disturbance or two that could bring some Tuesday-Wednesday rain and thunderstorms via a series of frontal passages. Right now we are dealing with the return flow of the departing high which is driving the hot and humid air mass. After the unsettled mid-week frontal passages, the newly approaching high pressure will bring N flow back to the region via front-side anticyclonic flow. This should set up warm and pleasant conditions from Thursday through at least the first part of the weekend (some maybe most of Saturday). Sunday looks unsettled as of right now due to another frontal passage/approaching high. It appears we’re stuck in a much more traditional late-spring/early-summer pattern…rather than the rain funk we were in.

Monday (June 18) high temperatures should easily reach into the 90s for most. I think there’s a chance of 100 along the I-95 corridor through Wilmington and into the Trenton/New Brunswick area. The immediate coast should stay the coolest but still reach well into the 80s. Another afternoon sea breeze front is possible like today and yesterday. It’s not impossible for such a sea breeze front to pop off a few isolated showers and/or thunderstorms. Otherwise skies should be hazy, hot and humid. Winds should be light-to-breezy out of the S/SW. Overnight lows should only fall into the 70s statewide. You might see some areas struggle to dip below 80 until the early hours of Tuesday AM.

Tuesday (June 19) high temperatures should start out warm and muggy. Most should reach the upper-80s/lower-90s before a cold front moves through sometime during PM hours. This frontal passage could trigger rain and thunderstorms for afternoon-evening hours. Winds should breezy out of the SW ahead of the front and light out of the N behind it. This should drop overnight lows into the 50s/60s statewide as some (not all) humidity is relieved.

Wednesday (June 20) high temperatures should reach the low-to-mid 80s for most. Immediate coastal areas could hang in the 70s. Skies should feature a mixed bag of sun and clouds with rain and thunderstorms possible. Winds should transition from NW to NE for most. Overnight lows should range from mid-50s to mid-60s NNJ to SNJ.

Thursday (June 21) high temperatures should reach the low-to-mid 80s for most. Immediate coastal areas could hang in the 70s. Skies should be partly sunny. Winds should be light out of the N/NE. Overnight lows should range from upper-40s to lower-60s NNJ to SNJ.

Friday (June 22) high temperatures should reach the low-80s for most. Immediate coastal areas could hang in the 70s. Skies should be mostly sunny with a pleasant feel. Winds should be light out of the E/NE. Overnight lows should range from upper-50s to upper-60s NNJ to SNJ.

An early look at the weekend indicates sunny and pleasant conditions lasting into Saturday. Sunday looks unsettled from this range. Let’s revisit in a few days. Everyone have a great week and please be safe! JC
