For the first time this season, parts of Iowa are under a Freeze Warning and residents in the far northwestern counties will need to take precautions if they hope to save their flowers and garden vegetables. Meteorologist Mike Fuhs, at the National Weather Service bureau in Sioux Falls, says the Freeze Warning runs from midnight tonight (Monday) through 9 A-M on Tuesday.  “In Lyon County, up in the far northwest corner, we are expecting temperatures to dip down to 32-degrees or less,” Fuhs says. “In the Frost Advisory counties, we are expecting a bit more mild temperatures with readings dropping down into the 33- to 34-degree range.”

Neighboring Osceola and Sioux counties are the ones under the Frost Advisory. Iowans in those areas who have still have blooming flowers, tomatoes on the vine or other tender vegetation, should cover those plants tonight with sheets, blanket or styrofoam cones. “This is the type of a freeze and frost that should -not- get down to the 20-to-25-degree range which would just kill everything,” Fuhs says. “Staying in the upper 20s and lower 30s, if you cover your vegetation up, it’s possible it will survive until the next freeze.”

While parts of central Iowa saw highs on Sunday in the 80s, Fuhs says that weather is gone for now, as a mostly-chilly week is ahead. “We’re looking at near-normal to just below-normal temperatures,” Fuhs says. “They will modify a little bit so we’re not expecting any more in the way of frost and freeze for the rest of the week but by the same token, it will have a difficult time warming up. Our warmest day of the week will probably be Thursday when temperatures get up into the upper 60s.”

Parts of central and southern Iowa may see highs in the low 70s on Thursday. Tonight’s first freeze for northwest Iowa is right on schedule, he says, as it usually arrives within the first ten days of October.

A FLASH FLOOD WATCH remains in effect until 7-a.m. Saturday for the following counties in Western Iowa:  Sac-Crawford-Carroll-Greene-Audubon-Guthrie-Dallas-Cass-Adair-Madison-Adams-Union-Taylor-Ringgold.

A FLOOD WATCH remains in effect until 5-a.m. Saturday for these counties: Harrison-Shelby-Pottawattamie-Mills-Montgomery-Fremont-Page.

FLOOD WATCH details: Occasional rounds of showers and thunderstorms with heavy rain potential are expected through tonight. Additional amounts of  1 to 3 inches are possible, which would put storm total rains from Thursday through tonight in the 2 to 6 inch range. Flooding of low-lying area, urban areas and eventually rivers and streams could result.

* In addition to the general flood threat, faster or flash flooding, could occur with some storms that may develop through this evening in southeast Nebraska and southwest Iowa.

FLASH FLOOD WATCH details: Widespread rainfall amounts of 1 to 3 inches of rain can be expected through Saturday morning, with locally higher amounts in excess of 3 inches likely. Rainfall rates will be heavy at times with the potential for rainfall amounts of 2 inches occurring in an hour or less.

* Heavy rainfall may lead to rapid rises on local creeks and streams which may be high enough to cross roadways, especially low lying areas. Significant ponding of water on roadways is expected at times as well. Flash flooding at night is extremely dangerous and drivers should turn around if they come to an area where water is flowing over the road.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a VERY DANGEROUS SITUATION. You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
