Mostly Sunny & Hazy Thursday, Pop up Showers Back on Friday. Heat Coming for the Weekend!
Wednesday Night Forecast Update
Wednesday Night Forecast for July 21st:
Smoke and haze was quite apparent across West Tennessee today from large wild fires burning across The West and Southern Canada. The smoke will continue to stick around until the winds shift back to the southwest on Friday. We could see a few showers popping up late in the week but the big story will be the heat coming in for the weekend. Forecast models are showing heat indices over 105° for many locations across the area Find out who will most likely see the showers on Friday and who is expecting the hottest weather this weekend coming up right here.
If you were wondering why it was hazy today here in West Tennessee, smoke is moving through our area from fires in Canada. Air quality has been lower as well. Smoke should mix out around Friday as winds start to shift with our next weather pattern. If you have asthma or bad allergies due to smoke you should limit the amount of time you spend outdoors and should avoid exercising outside until conditions improve. Here is a look at the smoke moving in the Mid South and the origins of where it is coming from.
Some isolated showers will continue to develop along the Tennessee/Mississippi border on the backside of a stalled out front and low pressure system. But as the system continues to move away the area, the showers will move out and the clouds will follow overnight. Expect mostly clear skies and calm winds for the majority of the night. Lows will fall down to the upper 60s by the morning.
Mostly sunny and mild weather will continue for most of West Tennessee on Thursday. The winds will come out of the east still early but shifting to more of a southerly flow by Thursday night. Highs will make it into the upper 80s and possibly 90° with a heat index into the mid 90s most of the afternoon. Chances for rain are NOT zero but the majority of us will not see much at all, rain chances sit around 10% into the afternoon. Overnight lows will fall down to around 70° by Friday morning.
Southwest flow on Friday will bring back our typical afternoon and evening July pop up storms that we have been dealing with most of the month. Chances for rain sit around 30%-40% on Friday and some of the storms could produce brief gusty winds, heavy rain and some thunder and lightning. Highs will make it into the upper 80s to near 90° again and skies will be partly cloudy. Friday night lows will fall down into the low 70s.
Forecast models are showing typical southwest flow and a mostly dry weekend now. Chances for rain sit around 10% each day but expect mostly sunny . Highs this weekend should reach the low 90s with morning lows falling into the low 70s. Some locations could get close to the mid 90s on Sunday. The heat index will be a factor with most of the region feeling over 100° at times in the afternoon and early evening hours so a pop up shower would be nice, but don’t count on seeing much.
Rain showers and pop up storms could return for some of us on Monday and stick around into the day on Tuesday. Strong or severe storms are not expected but with our typical pop ups, brief heavy rain, lightning and some increased winds will be possible. Highs are expected to be around 90° with lows into the low 70s. Skies are expected to be partly cloudy and the winds will vary in direction as a weak disturbance moves through the region.
Not only are we now officially in tropical storm season, we are still in the middle of our severe weather season. 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.
