Prior to that, tonight and Saturday will continue the great weather - perfect for the opening of the Mid-South Fair, the Memphis Tigers homecoming game, and any other outdoor events being planned. After lows in the 50s tonight, Saturday will see temperatures return to near the 80-degree mark.
Meanwhile, to our north, a large area of low pressure at the upper-levels of the atmosphere is taking shape over the western Great Lakes and will strengthen over the weekend, while slowly moving west into the Upper Mississippi River Valley (see image below). This unseasonably strong and large upper-level low will help to drag a surface cold front closer, and eventually through, the Mid-South region. Clouds will first begin to increase on Saturday night, but it will remain dry. The same will be true for the first half of Sunday, but by the afternoon, an area of rain and thunderstorms will develop and begin to push in from the northwest along and just ahead of the front. This rain will likely impact the Memphis metro for much of the evening and night, as the cold front slowly pushes east. Rain will then begin to move out Monday morning as the front clears the area.
|GFS Model forecast for Sunday night shows the strong, large upper-level (18,000 feet) low pressure system near the Iowa/Illinois border that will help push a cold front and rainfall into the Mid-South|
|NWS Total Precipitation through Monday evening, indicating 1-2” of rainfall in the metro area, most of which would fall on Sunday night|
Stay tuned to MemphisWeather.Net over the weekend for the latest on the increasing rain chances.
