Weather Extra Bar

Almost everyone saw some rain late last night through this morning. See the maps below on the amounts.

Sep 18 Rain Totals

The northern half of Jones County (NE of Cedar Rapids…yellow shading on the map) had heavy rain. The radar estimates are 2”+. The official report at the Dubuque Airport will be 0.77” of rain, but in town many reports were near 0.25”.

The clouds have been clearing this afternoon as a warm front pushes northeast across eastern Iowa. The warm front is bringing warmer temperatures and humid conditions with it. A mostly clear sky this evening will give us a chance to take a look at the Full Harvest Moon. Click here for more information I posted yesterday on the blog.

There is a slight chance of a shower/storm late tonight and early Thursday morning. The best chance of rain will be in the afternoon as a cold front is forecast to track through eastern Iowa. Here is the forecast position of the cold front Thursday evening.

Sep 18 Thu Eve Sfc Map

The top two maps below are the WSI RPM model showing the potential timing of the showers/storms. There is a chance of severe weather with these storms. Hail and high wind would be the primary threat.

Sep 18 RPM Model

The showers/storms will taper off late Thursday night…they might linger shortly after sunrise Friday. Everyone will see rain again with some locations more than 1”. The map below is the rain forecast from Wednesday evening through Friday evening.

Sep 18 QPF

I will say mostly sunny, on the forecast, Friday since a very small part of the morning is the only chance of rain and it will be tapering off. Most of the day will have plenty of sunshine. Mostly sunny weather will continue through the middle of next week. Cooler and less humid conditions will return during this time as well.
