Hot and muggy through Thursday, cooling and rain Friday & Saturday

Posted: Updated:
CHATTANOOGA, TN (WRCB) -

Good Tuesday.  We get no relief from the heat and humidity through Thursday.  Then, widespread rain and cooler weather will finally reappear.

A stubborn ridge of high pressure will keep the lid on the atmosphere.  That means lots of heat and humidity getting trapped at the surface, with little of it able to break through to produce rain or storms.  There is a weak boundary to our north that may bring some spotty storms to the area between 6pm and 8pm.  Today's high will get to 96 with a heat index of about 102 during the heat of the day. 

Wednesday and Thursday will be basically the same.  There will be no real chance of rain with temps in the mid to upper 90s.

Friday, a front will approach from the west.  Ahead of the front we will have an increase in clouds with scattered showers and storms in the afternoon ahead of the front.  That will keep the high at about 90.

The front will pass through on Saturday, and right now it looks as though we will have showers and storms likely through the day, ending Saturday evening.  Because of the rain expected, the high may not get out of the low 80s.

Sunday looks great.  Behind the front, cooler and drier air will settle in.  Sunday's high will get to 86 and the humidity will be a bit lower.  It should be a great day.

Next week, the heat and humidity will edge back up a little, but it should stay relatively nice through at least Wednesday with highs in the upper 80s and no rain.
