Hot and Humid then Slight Risk Late Sunday Night

This stagnant weather pattern we have been in continues again today. A stationary front sticks around to the north and a front lingers to the west. In between those two boundaries, we have a continued flow of air from the southwest. The air that is flowing in from the southwest is very warm and quite humid.

If you were looking for a break from yesterday’s heat and humidity…today won’t be your day. Highs reach the low to mid-90s from north to south.

A strong southwesterly wind unfortunately does not provide much relief from the summer-like conditions.

The front that sits to our north could fire up a few storms in our extreme northern areas, but the bulk of the storms stay into Minnesota and Wisconsin.

Another humid evening is on the way across the area. Lows only fall to near 70° with breezy winds. A stray storm is possible overnight, as well. A few more clouds track in for Monday, which may keep it a couple of degrees cooler than Sunday. Temperatures still land above average for this time of year.

Record Heat Possible This Weekend

This weekend’s forecast features the “triple H” = hazy, hot and humid. Plentiful sunshine helps temperatures today reach the 90s for all of eastern Iowa. On top of that, winds today come from a mainly southwesterly direction, meaning that it will continuously pull in warm air but also the winds pull humidity into the area. Winds today will be strong and gusty.

Air conditioning units will be on in full force this weekend. With heat and humidity like this, it is so important that you stay hydrated and always check the back seat before leaving your car.

We don’t see much relief from the humidity overnight. Lows fall to near 70° with breezy winds. Tomorrow, we make a better run for record highs. Once again, we soar into the low to mid 90s. Some record highs for the date tomorrow (June 11th) are from the 1920s and 1930s. Sunshine (and wind once again) will be abundant again for Sunday.

Increasing Humidity this Weekend

Our stretch of warm weather has begun in eastern Iowa. Today is one of the “cooler” days. Highs reach the low 80s to near 90° this afternoon. Humidity stays on the low side today, keeping things comfortably warm. A few showers and storms track through this afternoon into the early evening (severe weather risk is low). Not everyone sees rain today and some will only see sunshine on this Friday.

Tonight, as the temperatures fall, we feel a little more of the moisture in the air. If you’re planning a campfire, bring the water and a light blanket as overnight lows fall into the mid-60s.

Humidity slightly increases again during the day Saturday. Temperatures rocket into the 90s for most of the area tomorrow. The combination of heat and humidity brings the concept of heat index – how warm it feels outside.

Heat indices near 100° not only for Saturday afternoon but also on Sunday, as well.

Strong winds pick up on Saturday and continue into mid-week.

Rivaling Record Highs and Severe Storms Possible

After storms Monday evening, most of Tuesday will be pretty quiet. Partly to mostly cloudy conditions cover our skies. A front to our west will track very slowly to our area and that is why we keep cloud cover around. However, with us on the west side of the front, we’ll see strong southerly winds. Winds pull in more warm air and temperatures soar into the 80s and possibly low 90s (mainly along/south of I-80). Humid conditions will make it feel even warmer (hello heat index!).

Overnight, as the front tracks closer, we have the chance for showers and storms. Storms track through between 10pm and 2am Wednesday morning. Damaging straight line winds are the greatest threat, followed by hail and isolated tornadoes.

Scattered storms continue on Wednesday, some of which could be strong or severe. SPC issued a slight risk for all of eastern Iowa on Wednesday.

Check back for updates.

80°+ Temperatures across eastern Iowa

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

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.
