After much delay (and frequent whining and complaining by Mid-Southerners), it appears that summer weather may finally come to an end later today with the passage of our first autumn cold front. It will be a welcome change after yet another stretch of record high temperatures this week. In fact, the high temperature of 100 on Monday was the latest 100-degree reading in Memphis in recorded history (dating to 1850)!
The cold front will move through the Memphis area this afternoon with little initial fanfare. There could be a few showers along the front, but mainly an increase in clouds and a shift in the wind to the west, then north tonight. By Saturday, humidity will be falling and a steady northeast wind will make it feel much more pleasant, with a high in the mid 80s expected.
By Sunday, another sign of fall - a strong upper-level low pressure center that moves into the region - will appear. This low will cause an increase in cloud cover once again, which will help hold down temperatures to near 80 Sunday afternoon. A few showers will be possible Sunday afternoon and night as well. Computer models are still not completely agreeing on the exact track of the low, but it appears that Monday will still see the Mid-South under it's influence, so I'm forecasting more clouds than sun and a continued chance of rain. Temperatures will remain cool on Monday with highs in the 70s, likely the lower 70s.
As the low pulls away by Tuesday, sunshine returns and fair autumn weather takes hold with highs moderating to near normal by mid-week (lower to mid 80s) and lows in the 50s! For complete forecast details, check out the MWN Forecast.
