Another Changeable Week Ahead

After a fair and pleasant weekend, today turned hotter with highs in the lower and middle 90’s across Greater Nebraska. And Tuesday is shaping up to be a few degrees hotter.

High pressure over the Great Lakes is circulating a hot and moderately humid southerly flow over the area, and this pattern will continue through the day on Tuesday. After a mainly clear and mild night tonight with lows in the upper 60’s, Tuesday will see sunshine quickly send readings through the 70’s and 80’s and into the 90’s by early afternoon. Highs will reach the middle to upper 90’s by late afternoon, and the extreme southwestern Nebraska typical hot spots like Imperial may reach the century mark.

Humidity levels should remain moderately high, so heat indices could touch or exceed 100 tomorrow afternoon.

A cold front entering the country via North Dakota and Montana will reach northwest Nebraska tomorrow evening, and press through Greater Nebraska tomorrow night. While the front should come through mainly dry, I cannot rule out an isolated thunderstorm, especially over northern areas later tomorrow and tomorrow night.
Behind the front, Wednesday will be cooler with sunshine and highs in the middle to upper 80’s, so a nice day overall.

Unfortunately, the front will stall just south of Nebraska and then waver north and south from Thursday through the weekend. This will allow for the risk of at least isolated storms daily as disturbances ripple along it. The best chance of storms right now looks to be Saturday into Sunday morning as a strong disturbance rolls through. Highs will be generally seasonable in the upper 80’s to lower 90’s through the period with partly sunny to mostly cloudy skies.
