Warmest day of week; Rain arrives overnight

Hope you enjoyed the 4th of July weekend.  Now, it is time to head back to work for most.  It will be a warm day at work.  This should be the warmest day in over 20 days in Lincoln.

There has been a pocket of showers and thunderstorms from York to Central City, to Grand Island Tuesday morning.  The area is quickly decreasing in coverage area and intensity.  There will be a chance for a few scattered showers and thunderstorms as we go through the day, however most should remain dry.

Clouds may linger through the morning.  I am expecting skies to become mostly sunny for the afternoon which will allow for the mercury to quickly rise.  Highs should be in the upper 90°s throughout southeast Nebraska.  Humidity will also remain high, as dew point temperatures are expected to remain in the upper 60°s to lower 70°s.  This will send the heat index above 100° for another day.  Peak heat indices should be between 104° and 108°.

There is possible catch to Tuesday’s forecast.  If cloud cover should be able to hang on through the afternoon, temperatures would be held down to the upper 80°s to lower 90°s.

A few evening thunderstorms will be possible, but eyes will be watching thunderstorms develop along the South Dakota/Nebraska state line later Tuesday night.  The storms are expected to dive southeast, arriving to in southeast Nebraska during the overnight hours.  I am not expecting any severe weather from the storms, but an occasional higher wind gust could be possible from a few storms.
