How weather can impact voter turnout on election day

Believe it or not, there are things meteorologists track that can have an impact on voter turnout.

A 2007 study published in The Journal of Politics examined the impact weather has had on voter turnout for presidential elections from 1948 to 2000.  The authors of the paper state, "we find the linkage (to the weather-turnout hypothesis) not only to be statistically significant, but sometimes meaningful as well."

The findings suggest election day rain reduces voter turnout in a county by 0.9% per inch above the daily normal amount.  Not surprisingly, snow has a negative impact on voter turnout.  For every inch of snow that falls, above the specific day's normal amount, voter turnout drops 0.5% in a county.

The paper cites the 1960 and 2000 presidential elections as key examples.  Both elections ended in narrow margins, making several states pivotal Electoral College.

As an example, the 1960 presidential election was close in popular vote.  Only 119,450 votes (0.1%) separated Kennedy and Nixon.  Kennedy won the popular vote in Illinois by 8,858 votes.  There were allegations of voter fraud in Illinois during the election.  The weather was also relatively decent that day.  High temperatures were in the middle/upper 40°s across the state and light rain was recorded over the northern third.

If there had been more rain, deterring people from putting their vote in the ballot box, national results might have been impacted.  When the authors ran a simulation, taking the maximum rainfall for that election day in recorded history,  the results of the presidential election would have been different. Richard Nixon would have received an additional 106 electoral votes, thus winning the 1960 presidential election and becoming the President of the United States eight years earlier than his eventual election in 1968.

The authors also look at the opposite side.  What if there were dry conditions around the country on election day.  They found that it would have impacted the Electoral College in 1992 with Bill Clinton winning North Carolina and again in 2000 with Al Gore winning Florida, resulting in Al Gore winning the presidential election.  However, when they considered a wet 2000 election day, George W. Bush would have won by a wider margin.

Tornado Warning vs Tornado Watch

Do you know the difference between a Tornado Warning and a Tornado Watch?  Many people do not.  It all comes down to "when to take action" and "when to prepare to take action".  Here is an explanation of what each means and what you should do when one is issued.

A Tornado Warning is issued by your local National Weather Service office.  The warning is issued when either a tornado has been spotted or doppler radar indicates a tornado is imminent.  Most importantly, it is the time to TAKE ACTION.

Take shelter indoors immediately.  Go in to the location in your home, work, school, shopping mall or other building's location designated as your tornado shelter.  Oftentimes it is a basement or an interior room (bathroom, closet, or hallway).  You want to stay away from windows and put as many walls between you and the outside as possible.  If you need help determining a good location, check out this page from FEMA.

Tornado Warnings are issued for individual storms, known as storm-based warnings or polygon warnings.  However, for most, the warning is displayed for counties.  Make sure you know which county you live, work, and frequent so when a warning is issued, you know if you are included in the warned area.


A Tornado Watch is issued by the Storm Prediction Center when conditions are favorable for the development of severe thunderstorms capable of producing tornadoes.  When a Tornado Watch is issued, it is often in effect for six hours.

There are times when conditions exist that could produce strong tornadoes.  In this event, the Storm Prediction Center can issue a Particularly Dangerous Situation (PDS) Tornado Watch.  These are issued a few times a year.

A Tornado Watch is your "heads up" alert.  Usually, there is not an immediate threat, however it is time to prepare in case a Tornado Warning is issued within the next couple of hours.
This is the time to plan where to take shelter if a Tornado Warning is issued.

Make sure to enable your way of receiving Tornado Warnings.  Also, it is the time to keep an eye on weather conditions and have a way to monitor weather conditions - monitoring the latest from a trusted weather source.
