Weather Summary for Arkansas
National Weather Service Little Rock AR
925 PM CDT Thu Jul 19 2018

Another hot day was seen across the Natural State as quite a few
locations topped 100 degrees with most locations seeing heat index
values well over 100 degrees. This evening a strong line of
showers and thunderstorms moved into northern Arkansas. This line
of storms originated in Kansas and continued to push south through
Missouri before making its way into northern Arkansas before
sunset. This storm produced strong winds and knocked down trees
and power lines across northern portions of the state. This storm
system will continue to weaken through the evening and overnight
hours tonight.

In the coming days, high pressure aloft is forecast to strengthen 
over the region. This will result in diminishing rain chances for 
most areas, along with hotter temperatures. Highs Friday, will 
range from the mid 90s to around 103 degrees. 

Afternoon heat index values will range from 105 to 110 degrees in 
many areas Friday afternoon, with Heat Advisories already posted 
for part of Arkansas. Remember to drink plenty of water, stay in 
an air-conditioned room if possible, stay out of the sun, and 
check up on relatives, neighbors and pets.

Hazardous Weather Outlook For NEVADA County,AR

613 AM CDT Fri Jul 20 2018

 DAY ONE  Today and Tonight  

Dangerously hot temperatures with heat index values reaching or 
exceeding 110 degrees are expected areawide today. An Excessive 
Heat Warning is in effect as a result, and precautions should be 
taken to avoid heat-related illnesses. As much as possible, limit
outdoor activities to the early morning or early evening. Drink 
plenty of water, take frequent breaks in the shade, and exercise 
caution while out in the sun for even short periods of time. Wear 
lightweight, loose-fit, and light-colored clothing. Remember to 
check on those most susceptible to heat-related illness including 
the elderly, young children, and pets by making sure adequate air 
conditioning is available.

 DAYS TWO THROUGH SEVEN  Saturday through Thursday  

Very hot temperatures in excess of 100 degrees, with heat index 
values at or above 110 degrees are expected to continue through 
the weekend. Therefore, the Excessive Heat Warning is likely to 
be extended through Sunday. Heat-related headlines may even extend
into early next week before a gradual decrease in temperatures is
expected by mid to late week as the upper level ridge retrogrades
westward away from our region. Chances for thunderstorms will be 
increasing slightly during the mid to late week timeframe as well,
which may further aid in easing the prolonged heat wave.

 SPOTTER INFORMATION STATEMENT  

Activation of emergency management personnel, amateur radio 
operators, and storm spotters will not be needed through tonight.

...1930...
The temperature at Washington D.C. soared to an all-time record of 106
degrees. The next day Millsboro reached 110 degrees to set a record for the
state of Delaware. July 1930 was one of the hottest and driest summers in
the U.S., particularly in the Missouri Valley where severe drought
conditions developed. Toward the end of the month state records were set
for Kentucky with 114 degrees, and Mississippi with 115 degrees. (David
Ludlum)
