12:00pm UPDATE: Threat Increasing for Western Iowa

day1otlk_1630A slight increase in the risk for parts of western Iowa as sunshine is aiding in the destabilization of the atmosphere over this area.  Overall, the area under a slight risk for severe weather remains the same, but the Storm Prediction Center has bumped up the risk probabilities for wind, hail and tornadoes.

At this time, strong winds and large hail appear to be the primary threats, but an isolated tornado or two remains possible in the first hours of this severe weather event.  Storms are expected to ride along a frontal boundary draped across the state.  That boundary is expected to set up shop along the I-80 corridor this afternoon and evening.

Overall still not the most ideal set up for a chase, but we’ll continue to monitor the situation and bring you updates when needed today.

Besides severe weather, heavy rainfall is possible in the area this warm front sets up shop tonight.  Showers and thunderstorms will persist through the evening and overnight hours, finally tailing off sometime around sunrise.  Fortunately a few dry days has helped ease the strain on area rivers.  But with above normal levels along some water ways, the potential for flash flooding and river flooding could become a problem yet again this week.

We’ll see a break in the middle of the week before another round of rain moves in sometime this weekend.  For now we’ll keep our focus on today’s threat before moving on to the potential for severe weather tomorrow.
