Following Record Warmth, Here Come the Storms

day2otlk_0600[1]Well that didn’t take long.  With warm conditions and an slowly increasing amount of moisture returning to Iowa, the ingredients are beginning to come together for spring-time thunderstorms.  We could see some rumbles of thunder later today, but the better chance comes Thursday Night.  You can see in the graphic to the left that’s when portions of southwest Iowa will face a slight risk for severe weather.

For most areas this risk will begin closer to sunset and into the evening hours.  That’s when a low level jet will crank up and tap into modestly unstable air.  Dew points in southwest Iowa could reach the 60’s tomorrow, giving us our first taste of muggy air.

What is unclear at this point is the extent any storms that develop tomorrow night will have.  There are some indications the severe weather threat could last well into the evening, but at this time it appears any such threat would be scattered and not an organized outbreak.  The primary threats with any storms that develop is large hail and gusty winds capable of producing isolated damage.  Tornadoes do not appear to be a serious concern.

These storms will kick off a rather active weather pattern as periodic chances of storms become the norm.  By next week, a more organized chance of strong storms could enter the forecast, but that’s too far off to nail any details down.
