Temperatures have been heating up the past week as broad high pressure at the upper levels of the atmosphere has built over the region. Though not atypical of summer in the south, humidity levels have also been high, which has prompted daily Heat Advisories as heat indices have topped out in the 105-115° range.

A bit of history
However, for those who have been around the Mid-South their whole life (or at least the past 35 years), you’ll recall the wicked hot summer of 1980. During July of that year, there were 19 days with highs at or above 100°, including a record stretch of 15 consecutive days. That was also the year that the all-time record hottest temperature occurred in Memphis – 108° on July 13th.

A brief interruption in the heat
Into the weekend
The high pressure system has re-established its hold on our weather now though and it appears to remain entrenched right through the weekend. Thus we will see more mid to upper 90s highs, lows barely below 80, heat indices in the danger category, and nearly a zero percent chance of rain right into early next week.
Next week
By Tuesday/Wednesday, the ridge weakens a bit again (similar to earlier this week), which could allow for some airmass “popcorn” thunderstorms ahead of a weak front on those days. And just like earlier this week, the front itself will not move south of us. Thus cooler temperatures and lower humidity will again have to wait. Early signs are that the ridge of high pressure once again establishes itself over the region to end next week and temperatures remain well above normal as we head towards the end of July. Unfortunately there is little in the way of good news for those who like a break from the heat and humidity of the “dog days” of summer!
Heat Safety
We remind you that the effects of heat are cumulative – the longer it stays hot, the less capable people are of tolerating it. This is especially true for the youngest children, our older adult community, and those with medical conditions. Also, don’t forget about your pets! It may be the dog days, but that doesn’t mean your canine friends enjoy it more than you!
