 Public Information Statement  Statement as of 4:03 PM CDT on April 30, 2016


... 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.

Area forecast discussion 
National Weather Service Saint Louis MO 
315 PM CDT Sat Apr 30 2016 


Short term... (through late tonight) 
issued at 314 PM CDT Sat Apr 30 2016 


There remains the potential for a few severe thunderstorms to 
develop late this afternoon and early this evening along and south 
of a warm front that lies from west northwest to east southeast 
across the area. Clearing over western Missouri has allowed sbcapes 
to climb into the 1000-2000+ j/kg range. The rap still suggests 
this instability will move eastward into east central and southeast 
MO as well as southern Illinois by late this afternoon and this evening. 
Deep layer shear still support organized severe thunderstorms 
capable of producing some severe sized hail and locally damaging 
winds. The experimental hrrr reflectivity suggests that these 
storms will move out of the County Warning Area by mid evening. MOS guidance also 
suggest there may be some patchy fog developing after midnight 
across the area.

Long term... (sunday through next saturday) 
issued at 314 PM CDT Sat Apr 30 2016 


(sunday through tuesday) 


Upper low will move across Iowa on Sunday bringing a weak shortwave 
trough across the area. Will keep chance of showers and isolated 
thunderstorms going along and north of I-70 as it passes through. 
Sunday night still looks mainly dry before both the GFS/European model (ecmwf) brings 
another shortwave trough through the area on Monday. Will go with 
just a slight chance of showers across much of the area with this 
trough. Northwesterly upper flow will set up over the area by 
Tuesday with westerly surface winds, so will keep with a dry 
forecast. 


Temperatures will be slightly cooler on Sunday, and then even cooler 
on Monday as cold air advects into the area under cloudy skies. 
Temperatures should begin to moderate on Tuesday ahead of a cold 
front as winds turn out of the west. 


(Wednesday through saturday) 


Highly amplified upper flow will continue during the middle and end 
of the next week as an Omega block sets up over North America. We 
will stay under northwesterly flow aloft during most of this period 
with the upper ridge of the Omega block approaching from the west by 
Saturday. GFS and European model (ecmwf) are in decent agreement that a cold front 
will move through the area on Wednesday with just a slight chance of 
showers. Temperatures behind the front will be near normal with 
850mb temperatures in the 5-10c range until they behind to warm up 
by next Saturday.

Aviation... (for the 18z tafs through 18z Sunday afternoon) 
issued at 108 PM CDT Sat Apr 30 2016 


A warm front extending from just north of kcou to just south of 
the St. Louis region into southern Illinois will gradually advance 
northward this afternoon. Flight conditions should improve as this 
front moves north of the taf sites. This front passage may not 
occur at KUIN and at that terminal I still tried to be somewhat 
optimistic with at least some improvement this afternoon before 
IFR conditions settle in again at KUIN overnight and last into 
Sunday morning. Scattered thunderstorms should also develop this 
afternoon along/ahead of the cold front between 19-21z between 
kcou-kstl. I have a tempo group in the St. Louis area tafs to 
account for this threat. Shower and thunderstorm threat will 
largely remain displaced from the other taf sites. 


Specifics for kstl: 


Flight conditions should improve this afternoon as a warm front 
moves north of kstl. Scattered thunderstorms will also develop 
this afternoon along/ahead of the cold front between 19-21z 
between kcou-kstl. I have a tempo group in the taf to account for 
this threat between 22-01z. Potential for MVFR flight conditions 
overnight into Sunday morning due to fog as surface winds become 
light.
