A few more days before relief from heat and humidity

A warm, “muggly” day for southeast Nebraska.  Temperatures have risen to their highest levels in nearly two weeks.  The heat index has climbed to the 100°s today.  Lincoln had a heat index of 107°, the third highest level this year.  Looks like the heat and humidity will stick around for a few more days before relief comes for the end of the week.

Mostly clear skies tonight.  It will remain mild with lows in the upper 60°s to lower 70°s.

A cold front will try to move through southeast Nebraska Tuesday.  However, the front will begin to wash out and not bring much relief.  However, the front will allow for a few showers and thunderstorms to develop during the afternoon and evening.  The best chance will be for far southern Nebraska – south of Lincoln.

Temperatures will return to the lower 90°s Tuesday afternoon.  Dew points are projected to be in the lower 70°s, so it is going to feel very “muggly”.  Peak heat indices will once again return to the 100°s, mainly along and south of I-80.  Because of this, the National Weather Service has extended the Heat Advisory until 9 p.m. Tuesday.

Another Heat Advisory will likely be needed for Wednesday and Thursday as air temperatures are projected to top out in the middle 90°s and dew points in the lower to middle 70°s.  Heat indices will likely be over 100° area wide, and some locations will be 105°+.

Relief is expected to arrive Friday as high temperatures fall back to the 80°s and dew points fall through the 60°s and possibly in to the upper 50°s.
