On this day in Iowa weather history...

1898: Extremely heavy rain fell over a small area in northern Des Moines County beginning at around 10 pm on the 15th and ending at about 5 am on the 16th. There were no rain gauges in the affected area but a field survey conducted in the following days yielded incredible estimates of as much at 16 inches of rain, with the bulk of this falling in less than three hours early on the morning of the 16th. Localized but devastating flash flooding occurred, with remarkable accounts of large debris being carried over long distances and new drainage canals being cut through the earth by the tremendous volume of water. The field survey conductor noted that "Flint River, which formerly entered into O'Connell slough after paralleling its course for half a mile, cut a new channel directly through cornfields to the slough, tearing out many acres of soil with crops and timber." Fortunately, despite the fact that the flooding occurred in the pre-dawn hours there were no human casualties although much livestock was lost.

WHAT WILL WINTER BRING????????
JUST AS WE'RE GETTING OUT OF THE HOTTEST DAYS OF THE SUMMER SO FAR, WE'RE ACTUALLY GETTING A FIRST GLIMPS OF WHAT KIND OF A WINTER WE MIGHT HAVE.

HERE'S A FIRST LOOK:

FROM THE PACIFIC NORTHWEST, TO JUST NORTH OF LAS VEGAS, THRU SRN UTAH TO DENVER, INTO CENTRAL NEBRASKA/NW IOWA, AND INTO SRN MINNESOTA: BELOW AVERAGE TEMPS - ABOVE AVERAGE SNOWS.....

FROM NW IOWA, TO WISCONSIN - EAST OVER THE GREAT LAKES AND INTO THE NE U.S., SOUTH TO NRN KENTUCKY AND INTO SRN MO/NRN OK, AND BACK NORTH TO DENVER: THIS WILL BE THE WINTER BATTLE GROUNDS. IT WILL BE AN AREA OF EXTREMES. I WOULDN'T BE A BIT SURPRISED TO SEE HIGH TEMPS IN THE 60'S IN EARLY DECEMBER - WITH LOW TEMPS NEAR ZERO BY MID-MONTH. ANYTIME AN EXTREME SEASON OCCURS, EXTREME WEATHER IS ASSOCIATED. EXPECT OCCASIONAL HEAVY PRECIP TIMES, FOLLOWED BY EXTENDED DRY TIMES....IN THE END? WE SHOULD AVERAGE/NEAR NORMAL FOR HIGH AND LOW TEMPERATURES, AND NEAR NORMAL SEASONAL SNOWFALL. WE'LL JUST HAVE AN OCCASIONAL "SHOW-STOPPER" ALONG THE WAY...........

ELSEWHERE IN THE COUNTRY: SE U.S., SRN 1/4 OF U.S., AND SW U.S.: WARMER AND DRYER THAN NORMAL... IF YOU ARE A SNOWBIRD, IT WILL BE A GOOD WINTER TO GO SOUTH................
