More Rain for Waterlogged Houston and Some Rain for Us

A very productive and slow-moving system continues to dump a LOT of rain in a few areas of the nation.

An area of moderate to heavy rainfall continues to churn around Omaha and Council Bluffs and is expected to dump over an inch of rain in many areas of Western Iowa and Eastern Nebraska. We will have a few showers and thunderstorms tracking through the viewing area later, but they will be more spotty and may only produce a quarter- to half-inch of rain by the time the system tracks out of the area Thursday evening.

The cold front trailing from the low over us has produced a line of storms that is tracking toward Houston, TX and will produce more rainfall in the soaked city. ¬†While the storms are dying out, Houston is waterlogged and the rain will have nowhere to go. You can see the line of storms on the visible satellite loop from NOAA’s GOES-14 satellite this morning.

Heavy Snow in 1985

FROM NWS:

A winter storm struck Iowa from late on November 29th through December 1st producing heavy snow across much of the state. A wide swath from southwest to northeast received 8 or more inches with many stations from around Guthrie Center east northeast to Waukon and Dubuque recording a foot or more of snow. In northeastern Iowa Decorah, Dorchester, and Waukon all set their single-day snowfall records with Dorchester reporting a remarkable 18.0 inches of snow in just 24 hours ending on the morning of the 2nd. Other reported three-day snowfall amounts included 13.5 inches at Charles City and Waterloo, 14.0 inches at Independence and Waukon, 14.8 inches at Decorah, 16.0 inches at Tripoli, 16.5 inches at Oelwein, 17.0 inches at Fayette, 18.6 inches at Dubuque, and 19.0 inches at Elkader and Iowa Falls. Winds gusted to 40 to 50 mph by December 1st, combining with bitterly cold air to produce wind chills of -40 to -60 and resulting in blowing and drifting of snow that brought travel to a standstill across much of Iowa.
