Hot and dry weather turns cooler and wetter starting Sunday

Another warm weekend with near record-breaking temperatures, but we finally get a break next week! After an especially warm first three weeks of the month, we finally see some cooler temperatures behind this weekend’s showers. Starting on Sunday and leading into most of next week, we’ll see temperatures right around average, with some days even below. This decrease in temperatures doesn’t come without consequences however; we’ll see an increased chance for showers and maybe a thunderstorm or two come mid-week. 



Friday/Saturday: Will this heat ever end?

Short answer: yes. Long answer: More near-record temperatures – highs in the low 90s – kick off this weekend along with high winds! A warm and windy southerly breeze will help keep temperatures up along with the sun shining through a few clouds. Summer temps only start off the weekend though as a "cold" front moves through on Sunday, bringing cooler, near-average temperatures for the week ahead.

Saturday evening/Sunday

Chances of isolated thunderstorms increase Saturday afternoon but showers and thunderstorms are expected starting Saturday evening and throughout Sunday. Fans of the Storm Prediction Center Convective Outlooks have likely noticed that we are right on the cusp between a Slight (level 2) and Marginal (level 1) Risk for Saturday night. If things do take a turn for the worse however, and stronger storms take shape, we’re looking at main threats of small hail, high winds, and heavy rain (a typical May thunderstorm). Starting Saturday night and heading into Sunday, we start to see temperatures fall, with highs on Sunday peaking in the low 70s! 

SPC Day 2 Convective Outlook: Most of the metro appears to be in a Slight Risk (level 2) with some towns to the east of Memphis in a Marginal Risk (level 1) for severe weather.


Monday: A break from the rain

Temperatures stay in the 70s again on Monday, but conditions dry up, as rain chances decrease to start a new work week. Clouds will decrease, but a slight temperature increase will start on Monday as temperatures are expected to reach the upper 70s. They will increase a little more in the days following, though will still be cooler than the near-record temps we’ve had the rest of the month.

Tuesday/Wednesday

Temperatures increase and will peak in the 80s on Tuesday and Wednesday as more rain comes into the region. Showers are likely throughout both days and isolated thunderstorms, some of which may be severe, are not out of the question. These days will bring the highest temperatures of the week, likely only reaching the mid 80s as clouds and rain will keep higher temperatures away. 



Thursday/Friday

As of right now, temperatures look like they’ll decrease a bit by the end of next week, and chances for rain diminish. Highs towards the end of the week will be in the 70s, and overnight lows will stay in the 60s. There’s a slight chance for showers early on Thursday, but otherwise expect a few clouds, lots of sun, and below-average temperatures to cap off this upcoming week!

All in all, this week will bring more pleasant and spring-like conditions, like more normal temperatures and lots of rain. A cold front to start off and a high pressure system moving in by the end of the week will keep temperatures in the 70s most days, and in the 60s every night. Be prepared for lots of rain and remember that severe weather has not been ruled out yet!

April 2022 Climate Report for Memphis, TN

April Climate Recap

Coming out of a slightly warmer than average month of March, April returned to the slightly below average temperatures that marked the first couple of months of 2022. As typical for spring, temperatures varied from above normal to below normal as fronts crossed the region. By mid-month, the first 80s of the year arrived, though a front dropped highs back into the 60s  for a few days before returning to the 80s again. The multiple frontal passages resulted in a wet month as well, with precipitation above normal, even during the wettest month of the year. Five days recorded more than a half inch of rain, while thunderstorms on the 13th dropped over two inches.


Multiple days with thunderstorms resulted in scattered damage reports over the course of the month. The main event for the month occurred on the afternoon and evening of the 13th with multiple reports of wind damage, including trees downed, a funnel cloud sighting in West Memphis that prompted a Tornado Warning, and a few reports of flooding due to more than two inches of rain falling.
