TRACKING: Warm Temperatures, Several Rain Chances This Week

May 14, 2017

After an almost perfect weekend across the state of Iowa, the weather is going to turn a bit more active in the week ahead.

Tonight’s sky will be mostly clear to partly cloudy.  There is an isolated chance for a shower toward morning across the western counties, but for the most part we are dry.  Lows will be in the middle 50s northeast (closer to a front), and low 60s southwest.  Winds will be SSE at 5 mph.

Monday will be mostly sunny to partly cloudy and slightly humid.  Temperatures will be in the upper 70s to middle 80s.

Monday’s forecast by afternoon gets a little tricky.  There is the potential for a few thunderstorms to pop-up, especially later in the afternoon. Any storm could be strong to severe with hail as the primary threat.  We are not expecting any widespread storms, but nonetheless we will be on the lookout tomorrow afternoon and evening.  Another chance for storms exists, especially north, Monday night.

We are dry on Tuesday, before more rain and thunderstorm chances track in Tuesday night and Wednesday.  More widespread rain is expected (heavy at times), and there is also the risk of some storms turning severe.  Stay with KWWL for further updates.

Happy and Mild Mother’s Day

May 14, 2017

Happy Mother’s Day to all the moms of eastern Iowa. Whatever your plans are today, whether it’s being pampered or enjoying some quiet time, the weather (ie, Mother Nature) is going to cooperate. Much like yesterday, today will feature plenty of sunshine. Highs once again soar to 10° above normal highs today.

We reach the upper 70s and low 80s with an isolated neighborhood probably warming into the mid-80s. It will actually feel more like Father’s Day. Breezy winds today come from a southerly direction and continue to pull in mild air.

 

Overnight, a few more clouds track across our skies. We fall into the upper 50s to low 60s tonight. A system to our northwest reaches northwest Iowa tomorrow and will fire up an isolated storm in our area Monday afternoon. The severe threat is low at this point but hail is possible. Highs tomorrow reach the 80s once again with increased humidity. Humidity sticks around into Wednesday, helping to fuel more storms due to a passing front.

We see near normal highs at the end of the work week.

80°+ Temperatures across eastern Iowa

May 13, 2017

We are getting ourselves a taste of summer this weekend across the state of Iowa.  Here are the high temperatures from Sunday; All off us reached the lower 80s.

Average highs for Waterloo, Dubuque, Cedar Rapids and Iowa City don’t hit 80° until early June.  It’s been nearly 7 months since the thermometer reached 80° in Waterloo and Dubuque, while it’s only been a month for Cedar Rapids and Iowa City.

In the next graphic, we look at the earliest 80° and latest 80° in the year (January to December).  Notice, within the last 5 years each city has reached it’s earliest 80° on record.

June-like Temperatures This Weekend

May 13, 2017

Just two weekends ago, we were talking about wind chills and highs in the 40s. This weekend, highs are in the 80s. Mother’s Day weekend will be perfect for any outdoor activity to treat your mom. Lounging outside in a hammock or outdoor brunch/lunch won’t be interrupted by Mother Nature. Prepare for plenty of sunshine today and tomorrow, with highs in the low 80s.

Clouds increase during the day on Monday, ahead of a system that is off to our northwest today. That system may fire up some storms Tuesday and Wednesday, along with breezy winds. The severe risk is low at this point, but we will continue to watch the situation.

Tornado near Salem

May 10, 2017

There was a severe thunderstorm watch in effect for southern Iowa (along and south of Washington) this afternoon. A few storms turned severe with large hail and then there was one near Salem (Henry County). The storm produced a tornado. Here are a couple of photos of the tornado. A storm survey team, from the National Weather Service in the Quad Cities, will be out to assess any damage near Salem Thursday. This is done to come up with a rating of the tornado.

 

The tornado was reported just before 3:00pm. There was a report of a funnel cloud just to the southwest before the tornado formed.

The radar image below showed the core of the storm NW of Salem with the tornado likely on the south side of the storm.

Inside the red circle on the satellite image is the location of the storm at 3:00 pm.

The information below is from the Storm Prediction Center.

The tornado warning for Henry County and the Salem area was issued at 2:34 pm.

Severe Storms Possible Wednesday

May 9, 2017

Low pressure over southeastern Iowa will track off to the east. As it does, it takes the rest of today’s rain changes with it. Highs Tuesday: 65-75°.

Wednesday is the coolest day of the week, with highs running at least 5° below normal. Highs Wednesday: 62-69. Another low pressure along a previously stationary front will track just to the south of the Iowa-Missouri border Wednesday into Thursday. That brings another chance of showers and storms to the area.

Our southern counties are under a “Slight Risk” for severe weather Wednesday. Hail is the biggest concern, followed by damaging winds.

3PM Wednesday

7PM Wednesday

3AM Thursday

Behind the midweek system, we dry things out into the Mother’s Day weekend. Highs return to the 70s Thursday and stay there into at least next week.
