Weather Summary

Weather Underground midday recap for Tuesday, June 18, 2013.

Wet and unsettled weather continued for parts of the East and South on Tuesday as a cold front dropped southeastward across the Midwest and Northeast and reinforced another frontal boundary extending from southern New England through the Southern Plains. Rain and thunderstorm activity developed ahead the advancing cold front in parts of the Ohio Valley into New England, while a cooler airmass followed behind the cold front and led to cooler daytimes highs in the Upper Great Lakes and Northeast. Areas of scattered showers and thunderstorms developed near and to the south of the main frontal disturbance from the Mid-Atlantic and Southeast through the Central and Southern Plains. The Storm Prediction Center issued a slight risk of severe thunderstorms for parts of the lower Ohio Valley and eastern and central Carolinas through the afternoon and evenings. Areas of the Ohio Valley were at primary risks of damaging wind gusts and hail, while areas of the Carolinas remained at risk of damaging wind gusts.

Meanwhile, behind this activity impulses from from the West enhanced precipitation and thunderstorm activity in the High Plains and created the potential for strong to severe thunderstorms for a large part of the region. The Storm Prediction Center issued a slight risk of severe thunderstorm development from this afternoon through tonight with threats of hail and damaging wind gusts.

Elsewhere, an upper level low located off the Pacific Northwest coast brought progressively better chances for showers and thunderstorm activity to the Northwest. The Storm Prediction Center issued a slight risk of severe thunderstorm development for the Northern Rockies with hail and damaging wind gusts possible from this afternoon through tonight.

Public Information Statement
Mobile & Email Alerts Statement as of 1:54 PM CDT on June 18, 2013

... Safety rules for severe thunderstorms...

A Severe Thunderstorm Watch has been issued by the National
Weather Service. In the interest of public safety... the
following safety rules are provided. Public and commercial
broadcast stations serving the affected area are asked to
broadcast these safety measures frequently while the watch is
in effect.

A Severe Thunderstorm Watch means conditions are favorable for
the development of severe thunderstorms in and close to the
watch area. If you are in the watch area... keep up to date of
the latest weather information. These storms can develop
rapidly so there may be occasions when advance warning is not
possible.

A Severe Thunderstorm Warning means a severe thunderstorm has
been observed or indicated on radar. If you are in the path
or near the storm... take immediate actions to protect life and
property. Follow these safety rules:

(1) in open country... you should seek shelter and avoid trees
which can be targets for lightning. If there is no shelter...
go to a ditch or culvert but beware of rising water which can
cause flooding.

(2) when indoors... stay away from outside walls and windows
and go to an interior room on the lowest level. Avoid using
electrical appliances while the storm is nearby.

(3) in Mobile homes... you should leave and seek nearby safe
shelter.

(4) if swimming or on a boat... you should get to shore as
quickly as possible and find shelter.

A thunderstorm is considered severe when it contains one inch
or larger diameter size hail and/or wind gusts of 58 miles an
hour or greater. A severe thunderstorm can also produce deadly
lightning and very heavy rain which can lead to flash flooding.

Remember... with any severe thunderstorm there is always the
possibility of tornadoes.
