Flood Watch

IWN Flood Watch

IowaWeatherNow.net has issued a FLOOD WATCH for areas shaded above.

Date: 3/11/19 at 2:53pm CT

Timing: Effective Wednesday afternoon through Thursday morning…..

Discussion: Dense fog will develop Tuesday afternoon into Wednesday morning as a warm moist layer works over the cold surface. A surface low will trek from southeast Colorado to western Iowa and rapidly deepen later Wednesday into Thursday. As the surface low deepens it will put much of western Iowa in the northeast quadrant for heavy rains as a low level jet and increased instability transports 1-2″ precipitable water values into western Iowa. This section will get wind gusts over 30+ mph and rainfall totals up to 1-3″ with high rainfall rates included in the deformation zone. An area of snow showers will exist Thursday afternoon before the system lifts northeast of the area.
