Weather Summary

Weather Underground midday recap for Sunday, May 19, 2013.

Heavy rains and severe thunderstorm activity continued for the Plains on Sunday as a broad low trekked slowly across the Northern Plains. As the system progressed, counter-clockwise flow associated with the system pulled ample moisture and energy northward from the Gulf of Mexico, while an associated cold front reached southward from the system across the Central Plains. Forcing from the cold front combined with a dry line in the Southern Plains and the moisture laden conditions of the region allowed for multiple clusters of thunderstorms to continue from Saturday night through Sunday morning. Portions of eastern Kansas, western Missouri, and central/eastern Oklahoma remained at moderate risk of severe thunderstorm activity through the afternoon and evening as environmental conditions remained favorable for strong tornadoes, damaging wind gusts, and very large hail. Areas surrounding this moderate risk region from the parts of the Southern Plains into the Upper Mississippi Valley were at slight risk of severe thunderstorm development. While hail and damaging winds were the main threats of severe weather in these regions, a few tornadoes were also possible.

Meanwhile, heavy rains continued across the north-central U.S., while moderate to strong instability kicked up scattered thunderstorms and showers in the southeastern corner of the nation. Areas of eastern Montana through eastern Minnesota and parts of western Wisconsin remained under Flash Flood Watches and Warnings through the afternoon due to moderate to heavy rain and areas of rapid runoff. Flash Flood Warnings and various Flood Watches Warnings were also issued for parts of northern Georgia and eastern Alabama as intense rainfall amounts of 2 to 3 inches fell in one hour. In addition to heavy rain totals, hail and damaging wind gusts were possible with stronger storms in the southeastern corner of the nation.

Elsewhere, isolated to scattered showers and areas of thunderstorms developed across portions of the Mid-Atlantic and Northeast as a long warm front associated with this system reached across the Great Lakes into the Mid-Atlantic and humid conditions spread northward.

Public Information Statement
Mobile & Email Alerts Statement as of 6:27 PM CDT on May 19, 2013

... Safety rules for tornadoes...

A Tornado 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 messages
frequently while the watch is in effect.

The key to tornado survival is to be prepared and take immediate
action when a warning is issued or when you feel threatened.
Remember... the actions you take during a tornado event may save
your life and the lives of those you are responsible for.

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

A Tornado Warning means a tornado has been spotted or indicated
by radar... and you should take immediate action to protect
yourself and those around you.

Follow these safety rules to keep yourself safe:

(1) Mobile homes provide absolutely no protection from high
winds. If you live in a Mobile home... plan your escape to a
nearby sturdy building that will give you proper shelter. At
the first sign of an approaching storm go immediately to this
building.

(2) in homes... apartment complexes... or other small buildings...
go to the basement or to a small all-interior room on the lowest
floor like a Hall or bathroom closet. Use heavy furniture for
shelter or cover yourself with a mattress or blanket.

(3) in schools... hospitals... factories... or shopping centers...
go to designated shelter areas. Interior Halls on the lowest
levels are usually the best. Stay away from gymnasiums or
auditoriums. Avoid all outside walls and windows.

(4) never try to outrun a tornado in a vehicle. Traffic and the
layout of roads may block your escape. You should abandon cars
and trucks if a tornado approaches... and take shelter in a nearby
building.

(5) if caught in the open with no shelter nearby... find a
ditch... culvert or other low area and lay down flat. Cover your
head with your hands for protection.
