MEMPHIS WEATHER--Happy Valentine's Day everyone! Sunshine returns today and temperatures will spike into the mid and upper 50's this afternoon. What a treat for this special day! Clouds will be on the increase later tonight as a cold front drops into the Mid-South. Friday will be mostly cloudy and temperatures will be much cooler. Highs will only climb into the upper 40's and they will begin to slowly drop throughout the afternoon. Moisture is very limited with this weather system. Therefore, rain chances are extremely slim. A flurry or two can't be ruled out early Saturday as temperatures Friday night drop into the 20's. Saturday will be a cloudy and cool day, but sunshine and milder weather returns Sunday. Rain and thunderstorm chances are back in the forecast by Monday.
