Winter Storm Watch

IWN Winter Storm Watch has issued a WINTER STORM WATCH for areas shaded above.

Date: 2/18/19 at 8:20am CST

Timing: Effective now for Tuesday night through Wednesday night….

Discussion: An area of low pressure will work into the central plains from the south late Tuesday. Feeding on gulf moisture, this low will deepen Tuesday night which will place much of western Iowa in the northwestern quadrant for moderate to heavy snow. Heavy snow rates possible. Total snowfall accumulation of 4-8″ expected with locally higher amounts. This one will hit quick and hard late Tuesday night into Wednesday morning, so be prepared. The storm will move northeast of the area by Wednesday evening.


– Moderate/Heavy Snow

10 mile rule:  These alerts issued on this site means that within your zone and 10 miles from you will see the event forecast for.  You may or may not see the event but it means you are in the zone or 10 miles from where someone will.
