Heat abates slightly for the upcoming week

A cold front will move through the Memphis metro area this evening and stall across north Mississippi, bringing an end to the near-100 degree temperatures and Excessive Heat Warnings of the past week. It will also help to lower humidity levels a little by Monday, which was the second factor (besides the heat) contributing to the heat warnings. The Heat Warning will be replaced by a Heat Advisory along and south of I-40 (including the metro area) for Monday as it will still be hot by all accounts (mid 90s) with a little leftover humidity. Heat index values will be near 105 in the I-40 corridor.

As we head further into the week, the dewpoints (a measure of humidity) will slowly begin to rise again, though more cloud cover and daily rain chances (albeit low) will keep temperatures in the lower to mid 90s. Heat Advisories are possible, but we won't be dealing with the extreme heat like the past couple of weeks. There are some signs that point to a little more heat and humidity again heading into next weekend as the upper-level high pressure system rebuilds over the region. We'll wait to see how that pans out. In the meantime, check out the MWN Forecast for Greater Memphis for details on this week's expected weather.

After today's heat index value of 126.1 anything will be a welcome relief. These dewpoint temperatures are higher than anything I remember.
