Good Monday morning to you, South Jersey! I hope you all had a great weekend, and I hope you all were also able to stay cool. You'll certainly need to do so frequently this week, as we find ourselves firmly entrenched within a warm and uncomfortable air mass. Excessive heat warnings are in place for Gloucester, Camden, and NW Burlington county from noon today through 8pm on Wednesday. Heat index values in that region may reach and exceed 100 degrees, and while South Jersey (And Salem county too) is not in any heat advisory, that does NOT mean that we are exempt from any dangers due to high heat and humidity. Please be sure to stay cool by keeping strenuous outdoor activity to a minimum, stay in the shade or air conditioning, and be sure to drink plenty of water. I digress.
Last weekend's Bermuda high has now drifted far enough to the west where it is almost centered over the Delmarva Peninsula. It will continue its slow progression to the west over the next few days, so don't expect too much to change in the short term forecast. We hit 90 yesterday, so the creation of our third (and from the looks of things, longest) heat wave of the season will likely come around tomorrow when we have our third day of 90+ degree heat. We have to get there first, and today will be a rather hot one. A very weak frontal boundary will sweep though the area this evening, so a VERY isolated late day thunderstorm is possible. Otherwise, I think we stay dry, hot, and humid. Highs will reach the low to mid 90s on the mainland and mid 80s on the beach with a west wind at 5 to 15mph. We'll have another warm and uncomfortable night tonight with lows only reaching the mid 70s along with a light southwest wind at 5 to 10mph.
The rest of the work week can be summed up using the three H's of summer: Hazy, Hot, and Humid. High pressure will continue its slow march towards the Ohio River Valley before drifting southwards by the end of the work week. At any rate, we'll still remain well within the influence of that core of high pressure. Heat and humidity will remain rather high with air temperatures in the mid 90s on the mainland (Upper 80s on the beaches) and dew points in the low 70s...this will result in very high humidity values and heat indices that will likely toe the line of 100 degrees at times. There is a silver lining to all of this, and it arrives this weekend. A cold front is expected to sweep southeastward through the Mid-Atlantic, and as it does, cooler and more comfortable air may FINALLY arrive. We'll have to contend with some showers and thunderstorms to get there, but it's worth it at this rate. Highs start to decline on Saturday to near 90 degrees while Sunday has highs in the mid 80s on the mainland and near 80 on the coast.
Stay cool and have a great day!
