Memphis, TN – A dramatic temperature change is heading toward western Tennessee as summerlike warmth gives way to a much cooler weekend. Memphis is expected to reach 90 degrees Thursday, October 15, before temperatures fall into the 40s by early Saturday morning. The approaching cold front will also bring gusty northerly winds reaching 30 mph Friday, creating a noticeable change across the metropolitan area. By Saturday morning, the forecast low of 43 degrees will represent a 47 degree difference from Thursday's afternoon high.
According to the National Weather Service in Memphis, Thursday will remain sunny and unusually warm, with southwest winds of 5 to 10 mph. Conditions begin changing Thursday night as winds shift west after midnight and temperatures fall near 61 degrees. By Friday, much cooler air will spread across the region, bringing afternoon temperatures down to approximately 67 degrees.
Cold Front Brings 30 MPH Wind Gusts Friday Friday's arrival of cooler air marks the most significant weather development heading into the weekend. Northwest winds around 15 mph could gust as high as 30 mph, making conditions feel considerably different from Thursday's heat. Skies will begin mostly cloudy before gradually becoming sunny as the day progresses, according to the local forecast.
The temperature difference between Thursday's high of 90 degrees and Friday's high of 67 degrees is 23 degrees. Although this represents a substantial day to day cooldown, the larger 47 degree difference develops over roughly two days, extending into Saturday morning rather than occurring all at once.
Friday night will bring another drop as temperatures fall near 48 degrees. North winds of 10 to 15 mph could continue gusting to 25 mph, reinforcing the cooler conditions across Memphis and surrounding Shelby County communities.
Weekend Temperatures Fall Into the 40s Saturday morning is expected to deliver the chilliest conditions of the weekend, with temperatures near 43 degrees. Sunshine will return during the afternoon, although highs should reach only 65 degrees. North northeast winds around 15 mph could gust to 25 mph, keeping conditions breezy despite the clear skies.
The shift will be especially noticeable for residents planning outdoor activities, youth sporting events or early morning travel. Those heading out before sunrise Saturday should prepare for temperatures considerably colder than those experienced Thursday afternoon.
Motorists traveling Interstate 40, Interstate 55 and Interstate 240 may encounter gusty conditions Friday and Saturday, particularly along exposed roadway sections and bridges. The forecast does not indicate rain, snow or ice, and no weather related highway closures are identified in the supplied information.
Sunshine Returns as Temperatures Gradually Recover By Sunday, October 18, conditions will begin moderating as sunshine continues and temperatures reach approximately 70 degrees. East winds around 5 mph should provide a calmer afternoon, while mostly clear skies Sunday night allow temperatures to fall near 47 degrees.
The warming trend continues Monday with a projected high of 73 degrees, followed by 77 degrees Tuesday and 81 degrees Wednesday. This gradual recovery will bring Memphis closer to the warmer conditions experienced before the front, although the supplied outlook does not indicate another 90 degree afternoon during the period.
The National Weather Service forecast shows dry conditions throughout the available outlook, with no measurable precipitation chances listed. Residents should prepare for a brief but substantial cooldown before warmer weather returns next week.
