A flood watch is in effect today, according to the National Weather Service.
Heavy rainfall may result in widespread flooding today in the region, the weather service said.
Periods of thunderstorms are expected across the region through much of the day. These storms may produce widespread rainfall amounts approaching two inches, with locally higher amounts possible.
Temperatures are expected to drop from 43 degrees today to 33 degrees tonight, and there is a chance of snow or rain in Thursday's forecast.
Heavy rain last night and light rain this morning was recorded at about an inch of precipitation, according to the weather service.
The weather service warned of rapid rises on area creeks and streams, which may ultimately lead to flooding on many area rivers and tributaries. Farm land and low-lying areas may be prone to flooding.
A check of the major rivers on the hydrology chart this morning did not show any major rivers near flood stage in Wyandotte County.
