A Few More Storms...

After Wednesdays' development of storms into northwest Iowa, and continuance into central Iowa; more storms developed on Thursday over portions of northern and eastern Iowa. Yesterday's (Thursday's) storms were not as potent, only isolated severe thunderstorm warnings were issued for mainly marginally severe hail. Some brief funnels were possible with the storms, however, no reports were received. Nickel sized hail, and a wind gust of 59 mph were the only severe weather reports listed over the state of Iowa yesterday. The hail report coming from Tama county, more specifically 8 miles southwest of Tama, IA. The wind report was measured by an RWIS station near Williams, IA in Hamilton county.

Another note on the storms that occurred on Wednesday, the there will officially be a tornado in Iowa. A portion of a hog barn was destroyed around 6:08 PM, 2 miles northeast of Lake Park. This hog barn, and associated crop damage downstream, along with radar imagery of the low level rotation that was occurring at this time did confirm that this may have been a tornado. It will be confirmed as an EF0 tornado. I went back to the GPS logs, and at this time we were approximately 5 miles south of the tornado's location. The very wet RFD forced us to move south to have any view whatsoever of the storm.

Back to the current weather, dense fog is occurring over a majority of the state this morning. Some areas may be quite dense, leading to visibilities of less than a quarter of a mile. This fog should begin to lift as the sun rises and begins to warm us up, however, the fog should be prominent up until 9 AM in most areas. Highs today should range from the upper 70s to lower 80s, under partly to mostly cloudy skies. A few more isolated thunderstorms are possible this evening and into the early overnight hours, mainly for central and eastern Iowa. Lows tonight should be in the mid to upper 50s across the state as we head into the weekend.

Highs over the weekend look to range from the upper 70s to mid 80s from east to west. Lows overnight on Saturday should be in the mid and upper 50s; Sunday overnight in the upper 50s to lower 60s. A few isolated showers and storms are possible Saturday in the eastern quarter of the state. Otherwise mainly dry over the weekend as our next system moves into the state early next week.
