Heat Grip Relaxes a Few Days
(Tuesday, June 23, 2009) – Very high dew point temperatures (a measure of the amount of moisture in the air) and the hot air temperatures combined to push heat index values into the 110 category this afternoon. In North Jackson our high temperature was 96º with the highest heat index at 111º. McKellar-Sipes Regional Airport hit 97º today. Bemis topped out at 98º.
The frontal boundary mentioned in this mornings brief has almost pushed west to the MS River now. Thunderstorms have formed in the more humid air to the west of the boundary. This is well depicted on the satellite image above. Other isolated storms are noted on radar that could drift into or form around West TN. Most areas will remain dry.
Air that is drier and not as hot will settle in over the region for the next day or so and then the hot weather will take the stage again with dangerous heat index values returning by Friday. The next rain chance worth noting will begin Sunday.
Heat warnings and advisories will expire at 7 PM.
