Excessive Heat Watch and 100° Heat

The National Weather Service has issued an excessive heat watch for most of the area. Heat indices (the combination of the air temperature and the dew point) are expected to exceed 100°, and could be as high as 110°. The watch begins for some western counties on Wednesday and the rest of the area on Thursday. The entire watch will end on Saturday.

Actual air temperatures will top out in the mid 90s, which isn’t too far off from what we’ve seen in the past couple of years. However, the National Weather Service hasn’t issued an excessive heat watch since July 2011.

Though it will feel like 100+° during the afternoon on Thursday, Friday and Saturday, air temperatures have not been that warm since 2013. The chart below shows the last time the temperature was 100° or warmer:

City Date Temperature
Waterloo 7/25/12 104°
Dubuque 8/30/13 100°
Cedar Rapids 7/25/12 101°
Iowa City 9/8/13 105°

Cooler air (with highs in the 80s) is expected to track in on Sunday.

New Forecast Point for Upper Iowa River

The Upper Iowa River now has a new forecasting point in Winneshiek County.  The new gage is located just east of the town of Bluffton.

1

The new forecasts will describe the river conditions just upstream of Bluffton, downstream just a few miles to the Ten Mile Creek.  These forecasts will be issued when rainfall or snowmelt will cause the flooding along the Upper Iowa River.

Lightning Awareness Week 2016

June 20-24, 2016 is Lightning Awareness Week.

Lightning is one of the top three causes of death from thunderstorms. There is no safe place outdoors during a thunderstorm. Always remember “when thunder roars, go indoors”. Many people are struck before or after the storm. This is because they wait too long to take shelter or go back outside too soon. A good rule of thumb would be to wait at least 30 minutes after the last rumble of thunder. This assures that the storm has tracked a decent distance away from your location.

LightningTest

Number of lightning deaths in the United States by year

 

So far this year, there have been 6 deaths due to lightning strikes. None of these happened in Iowa. Some believe that it is dangerous to approach someone after he/she has been struck. That is false and lightning strike victims need immediate help. Call 911 and then apply CPR, you could save a life.
