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.
