Comfortable night ahead; Heat and humidity return

A fantastic late June day across southeast Nebraska.  Low humidity – dew points have been in the 40°s – and the temperature has been below normal in the middle to upper 70°s.  Monday will go in the weather records as “below normal”, making this the first day below normal in eight days.

We have a very comfortable evening and night coming.  Skies will clear Monday evening, allowing temperatures to drop to the lower to middle 50°s by Wednesday morning.  I wouldn’t be surprised if a few cooler locales drops to the upper 40°s.

It will be about ten degrees warmer Tuesday afternoon.  Skies will turn partly cloudy by afternoon and winds will increase out of the south/southwest gusting to 25 mph.  Highs will be in the upper 80°s to near 90°.

We will be watching for the potential of a few thunderstorms to develop late afternoon/evening in northeast Nebraska.  The window for initiation of the line is between 3 p.m. and 6 p.m.  The line is projected to move south, through eastern Nebraska.  I am bracketing the hours between 7 p.m. and 10 p.m. for the line to pass through Lincoln.  The main threat for any storms that develop will be straight-line winds and small hail.

Humidity will slowly be on the increase Tuesday, but you will notice it more Wednesday and Thursday.  Dew point temperatures should return in the middle/upper 60°s Wednesday.  Then we turn “muggly” for Thursday with dew points in the lower 70°s.  Combined with air temperatures in the middle to upper 90°s and the heat index will likely hit 100° Tuesday and 102° to 106° Wednesday.
