Cooler Overnight, A Heatwave Returns Next Week

Saturday Update

June 18, 2022

Storm Team Weather,

Sunday Night Forecast Update for June 19th:

Saturday’s official high as of 5 pm was 89 degrees and provided we don’t go another degree higher that would put us on track for the coolest day in about the last several days and later into the evening and overnight looks quite pleasant as we’ll fall out of the 80’s through the 70’s towards the later evening and drop to around 58 towards the Tennessee River with around 60 for the central and western areas.

TONIGHT:

Dewpoints will continue to decrease a little more into the overnight as as temperatures fall to around 59-61 by morning. Combined with a light northeast breeze and the lowest dewpoints in several days, it will feel a little cooler again in the morning.

Monday:

Although we’ll start off cooler and pleasant in the morning hours, temperatures will rise quickly in the afternoon along with the humidity. It will start to feel hot and humid quickly into the afternoon and evening tomorrow as the heat starts to make a big return. Winds will turn more out of the southeast and we’ll loose the more pleasant northeast flow we’ve had through the weekend.

NEXT WEEK:

The heat will be coming back with a vengeance for the following week. The forecast looks to be hotter than last week with many locations in West Tennessee approaching the 100° mark for several days in a row (not factoring in the humidity). The records next week are around 100-101° each day and many could be in jeopardy or fall in Jackson. We are expecting plenty of sunshine most of next week and as of now, rain chances look quite slim and below 10% every day next week. Monday highs will reach the mid 90s but upper 90s are likely for Tuesday through Friday and each day during that stretch 100° will be possible. The winds will come out of the west or southwest, and that may keep the humidity in check some, but will aid in the actual temperatures. We might see a few more clouds in the middle of next week and if we do see a few pop ups showers or storms, Wednesday and Thursday might be your best chance. Summer officially kicks off on Tuesday.

*Just off to our west, Another heatwave continues as extremely hot air has surged all the way into south central Canada! In fact, a temperature of 100 degrees was reported in the far north of Bismarck North Dakota! Some of that heat will ultimately arrive back into west Tennessee next week as the weak cold front that brought a slight cooldown mixes out and another hot ridge of high pressure builds into the region.

FINAL THOUGHT:

We saw our first 90° day on the year on May 11th and some mid to upper 90s are expected over the next few weeks. Meteorological Summer started on June 1st, but the official start of summer will be on Tuesday June 21st, and there will be more chances for severe weather though as we approach the start of summer. So you need to stay weather aware to changing weather patterns and monitor the forecasts closely. We got you covered in the WBBJ 7 Storm Team Weather Center as always.
