Heat continues for two more days

Memphis International Airport tied another record low temperature this morning - the maximum low for the day. Provided a stray thunderstorm doesn't cool it off before midnight tonight, we will tie the record of 81 set in 1978. Given the extreme heat and abundance of humidity, the National Weather Service has pulled the Excessive Heat Warning out of the bag of tricks for the second time this week. High temps will top out in the upper 90s to near 100 today with the humidity making it feel like 105-110 this afternoon. Stay indoors if possible, or make sure you are taking plenty of precautions if you must be in the heat.

The heat- and humidity-breaking cold front we have been waiting for for almost two weeks now arrives tomorrow (see the map above valid at 7pm Sunday)! With only a small chance of thunderstorms, the high for Sunday will still be near 97, so Heat Advisories will likely still be in effect. However, behind the front much drier air infiltrates the Mid-South and "cooler" temperatures (actually, just closer to normal) move in too. For the start of the work week, high temperatures will be near 90 to the lower 90s with negligible humidity. The best part will be the mornings when lows will drop into the 60s!! it will continue to be dry throughout most of next week with moderating humidity levels. No extreme heat is in the extended forecast though after this weekend!
