 Public Information Statement  Statement as of 3:36 PM CDT on July 6, 2015


... 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.

.SHORT TERM:  (THROUGH LATE TONIGHT)
ISSUED AT 320 PM CDT MON JUL 6 2015

TRANQUIL WEATHER HAS COME TO AN END. HEATING OF THE VERY MOIST
AIR MASS HAS PRODUCED SBCAPE OF 3000-4000 J/KG WHICH ALONG WITH A
WEAK UPPER DISTURBANCE TRACKING INTO EASTERN MO HAS GENERATED
SCATTERED THUNDERSTORMS ACROSS THE SOUTHEAST HALF OF THE CWA. PWS
OF 1.6-1.8 INCHES IS RESULTING IN HEAVY DOWNPOURS WITH STORMS,
AND PRESENCE OF SUFFICIENTLY STEEP LOW LEVEL LAPSE RATES AND
PRECIPIP LOADING IS ALSO AIDING IN PROMINENT OUTFLOWS AND GUSTY
SURFACE WINDS. SOME OF THIS ACTIVITY WILL LINGER INTO THE EARLY
EVENING PRIMARILY FROM ST. LOUIS EAST, BUT THE MAIN SHOW WILL BE A
GROWING EXTENSIVE BAND OF SHOWERS AND THUNDESTORMS CURRENTLY
EXTENDING FROM NORTHWEST MO INTO EASTERN KS. THIS ACTIVITY WILL
MOVE EAST AND SINK SOUTH WITH TIME TONIGHT. THE GREATEST THREAT OF
HEAVY RAIN WILL BE CENTERED IN NORTHEAST MO AND WEST CENTRAL IL
TRAILING INTO CENTRAL MO AND MAINLY THIS EVENING. THE CURRENT
FLASH FLOOD WATCH HAS THIS WELL COVERED. THE SEVERE WEATHER
THREAT WILL OCCUPY THE SAME GENERAL REGION AND TIME SPACE AND WILL
LARGELY BE DRIVEN BY THE AFOREMENTIONED INSTABILITY WITH MARGINAL
DEEP LAYER SHEAR SUPPORTING A MULTICELL MODE AND WIND DAMAGE
THREAT.

.LONG TERM:  (TUESDAY THROUGH NEXT MONDAY)
ISSUED AT 320 PM CDT MON JUL 6 2015

THE SCENARIO HAS CHANGED LITTLE TUESDAY INTO WEDNESDAY WITH THE
FRONT GRADUALLY MOVING SOUTHWARD AND BECOMING STATIONARY ACROSS
SOUTHERN ILLINOIS AND SOUTHEAST MISSOURI BY TUESDAY EVENING, AND
THEN WAVERING BACK NORTH LATE TUESDAY NIGHT-WEDNESDAY WITH THE
MOVEMENT AND PASSAGE OF A SURFACE LOW MIGRATING ALONG THE FRONT.
BROAD DEEP LOW LEVEL CONVERGENCE ATTENDANT WITH THE FRONTAL ZONE
ALONG WITH AMPLE INSTABILITY AND ABUNDANT MOISTURE /PWS IN EXCESS
OF 2 INCHES/ SUPPORT THE FORECAST OF WIDESPREAD SHOWERS AND
THUNDESTORMS WITH A HEAVY RAINFALL THREAT. THE CURRENT FLASH FLOOD
WATCH COVERS THIS PERIOD WITH MULTIDAY RAINFALL TOTALS OF 2-4
INCHES EXPECTED AND LOCALLY HIGHER TOTALS. ULTIMATELY THE WATCH
MAY NEED TO BE EXTENDED INTO WEDNESDAY NIGHT-THURSDAY NIGHT PERIOD
WITH ANOTHER AND THE FINAL SURFACE WAVE MOVING ALONG THE FRONT.

THE FRONT FINALLY PUSHES NORTH OF THE AREA BY EARLY FRIDAY PUTTING
AN END TO THE PRECIPITATION FOR SEVERAL DAYS. SUMMER HEAT AND HUMIDITY
