Flash Flood Watch for Whiteside County

It was a soggy Wednesday morning with a MCS or Mesoscale Convective System(large complex of storms) morning ENE though the Stateline area. Janesville in southern Wisconsin picked up just under an inch; and Dixon who saw 3-5" last week received 1.61" of rain this morning.

Much of today will end up being dry, but more storms are forecast to redevelop late today ahead of our next cold front. These will bring more heavy rain producing storms across the region, though it is expected to be more scattered in nature. Still, Whiteside county who picked up heavy rain this morning, will likely see more rain tonight. Because there is a lot of available moisture to work with in these storms later on ( our dew points are in the low 70's) and the ground is already saturated from rain this morning, any additional heavy rain tonight and early tomorrow morning will bring a threat for localized flash flooding. Because of this, the National Weather Service has issued a Flash Flood Watch for Whiteside county from 7pm  through Thursday morning.

Shower and storm activity looks to fire up around 7 to 8 pm tonight and will linger into the morning. The converge in any rain and storms we see will likely stay scattered, with the strongest storms to the west and south of the area. Storms and showers will then sink south late tomorrow morning into the early afternoon along the cold front and keep the general storm activity to the south and east for most of Thursday.
