Same Parts Of Nation Flooded All Summer Getting It Again

Today, these areas of the nation are subject to flash floods. The area
in red, mostly in Iowa, is most at risk, but anywhere from Kansas
to Wisconsin is under the gun.
My place in northwestern Vermont has been too dry this summer, but the opposite has happened here in Yankton, South Dakota, where I'm staying for the week with relatives.

It has rained and rained and rained out here this summer in a location that is usually a little dusty this time of year.

My mother in law's basement flooded a couple of times, and the community garden in Yankton was pretty much wiped out when a creek overflowed earlier this summer.

On the bright side, the flowers I planted for my mother-in-law back in May are doing better than I expected.

The rain and flooding has been even worse a little further to east in eastern Nebraska, Iowa and Wisconsin with repeated flooding events. And it's getting worse.

Since I got to Yankton on Friday, I have seen wave after wave of torrential thunderstorms march across Nebraska, Iowa and Wisconsin, setting off severe thunderstorms and repeated flash flooding. Mercifully, so far, hese storms have missed Yankton, and we have only had a couple of bouts with drizzle.

This weather pattern is going to continue for the next few days, and with saturated ground in parts of the Midwest, there is a really significant danger of additional dangerous flash floods.

Today, the greatest risk of flash flooding seems to be over Iowa, northern Illinois and southern Wisconsin as one thunderstorm after another is expected to roll over this region in a stalled weather pattern.

It looks like Iowa, Wisconsin and surrounding areas will remain under the gun on Labor Day.  If anything, the flood risk in this region could get worse on Tuesday before cold front diminishes the chances of heavy rain starting Wednesday.

Meanwhile, parts of Pennsylvania are picking up the pieces after yet another round of flooding on Friday. Areas around Lancaster, Pennsylvania were especially hard hit. Pennsylvania, New Jersey, Maryland and other areas of the Mid-Atlantic have been pummeled by flooding all summer.

Luckily, it's temporarily looking a little drier there for the next few days, so only isolated flash flooding from widely scattered, slow moving thunderstorms is expected.

VERMONT UPDATE

We're still waiting on an end to summer and more rain in the Green Mountain State, and we're going to have to wait awhile longer. It will generally be very warm and humid through at least Wednesday, with the worst days being Monday and Wednesday.

Those days will be well into the 80s with high humidity and heat indexes in the 90s. It will be vaguely cooler and drier on Tuesday, but not by much. There are chances of thunderstorms here and there, especially Monday afternoon and evening in the north, but not everybody will get them and they won't last long.

Which means we won't get the soaking rains we need. Some sort of cold front on Thursday will probably push the warmth, humidity and showers out of the picture.

The weather this upcoming weekend is still a bit uncertain, but there's the potential we could finally get some true autumnal weather. It's possible high temperatures on Saturday might only get into the 60s, if a high pressure system to the north prevails.

If this high really takes charge, we'd end up with those cool temperatures, bright sunshine, low humidity and a brisk breeze. We'll see on that.  I'm also entirely not sure if this potential cool weather really, truly marks the end of the summer heat until next year.
