Area Forecast Discussion National Weather Service Memphis TN 628 AM CDT Fri Apr 16 2021 .UPDATE... Updated 12z Aviation Discussion. && .PREV DISCUSSION... /issued 401 AM CDT Fri Apr 16 2021/ DISCUSSION... Currently...A quiet morning is underway across the region. A good deal of mid/high cloudiness has spread into the region. Temps are generally inn the lower 50s with a light N/NE wind. A weak disturbance moving across SE KS/SW MO is resulting in some rain across that area. Some of that activity may push into NE AR briefly this morning. Expect this to be short lived as the disturbance weakens as it moves into shortwave ridging aloft. Today and tonight...A good chunk of the day will be rain free with temps climbing into the low to mid 60s. Late this afternoon a mid level trough will approach and rain chances will increase across western areas spreading east tonight. Though most places will get wet this will not be a major rain producer. The majority of the area will see less than one-quarter inch of rain. Saturday and Sunday...A few lingering showers are possible early across north MS and along the TN River otrw expect generally cloudy skies with maybe a few breaks in the afternoon. Highs will remain below normal in the 60s with lows Saturday night in the 40s. An upper level disturbance moving through Sunday afternoon could bring some showers and perhaps even a thunderstorms to the northern counties. Highs again will be in the 60s with lows in the 40s Sunday night. Monday through Thursday....Broad upper level troughing across much of the country will result in continued cool springtime temps for the Mid-South with highs in the 60s Monday. A potent cold front will push into the area late Tuesday into Tuesday night with chances for rain. Some models are even hinting at some snow mixing in late Tuesday night but it is a little early to jump on that. Some places could dip into the upper 30s Wednesday morning despite wind and lingering clouds. Wednesday looks like a chilly day with highs in the lower 60s along with a stiff northwest wind. Thursday morning has the potential to be especially chilly with surface high pressure forecast to be directly over the Mid-South. Frost could be an issue. Dry and cool weather will continue into Thursday with the end of the week into Saturday looking wet. SJM && .AVIATION... /12z TAFs/ VFR conditions will continue to persist through this afternoon. Showers will begin to move into western sections of the Mid- South during the day on today with a better chance of rain Friday evening. Winds will be mainly from the northeast at 5 to 10 knots overnight before shifting to the southeast on Friday. By tomorrow morning showers will likely affect most of the Mid-South.
