Severe Weather Alert Descriptions

 Public Information Statement  Statement as of 4:05 PM CST on March 5, 2015


... Illinois and Missouri severe weather awareness week...
... Severe thunderstorm day...

Severe thunderstorms pose a threat to life and property. They
produce large destructive hail... one inch in diameter or greater...
and/or damaging wind gusts of 50 nautical miles per hour (58 mph)
or greater. Flooding rains... frequent cloud to ground
lightning... and tornadoes are also possible in severe thunderstorms.

A Severe Thunderstorm Watch means severe thunderstorms are possible
in the next few hours. Be prepared.

A Severe Thunderstorm Warning means a thunderstorm capable of
causing property damage and injury has been sighted or detected by
radar. Move to a safe building and stay away from windows.

Damaging straight line or downburst winds from a thunderstorm can
do as much damage as a weak to moderate tornado... so take severe
thunderstorm warnings seriously.

Very large hail... golfball or larger... is a major cause of property
damage in the United States every year. Protect your property if you
can... but make sure you get inside a safe structure to protect
yourself from the hail.

Lightning is the most frequent important weather threat to personal
safety during the thunderstorm season. Keep these lightning safety
tips in mind.

Plan ahead and avoid dangerous lightning situations. Check the
latest forecast before going outdoors for extended periods. Watch
for storms and seek shelter indoors when storms approach.

Lightning often strikes the tallest object. If caught outdoors
during a storm... dont stand next to tall trees or power poles. And
dont be out in an open area where you may be the tallest object. A
closed... hard top metal vehicle is safe in a thunderstorm. An open
structure such as a picnic shelter will keep you dry but it will
not protect you from lightning.

Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
630 PM CST Thu Mar 5 2015 


Short term: (through late tonight) 
issued at 250 PM CST Thu Mar 5 2015 


Another cold night is expected across the region. High pressure 
currently centered through the mid MS valley will gradually 
retreat eastward tonight with southerly winds and low level warm 
advection developing in its wake. The impacts of this will be most 
pronounced across the western part of the County Warning Area where southerly 
winds will develop by late evening. Meanwhile a well-defined 
short wave trof currently moving through the north Central Plains 
will also dig into the area overnight bringing an increase in mid- 
high clouds to primarily northern parts of the County Warning Area. The result 
will be the coldest temperatures tonight will be across the 
deepest snow cover and where winds remain light longest which will 
be southeast MO and southern Illinois. This is where I have dropped 
temperatures a good deal from the previous forecast with mins in 
the single digits to just below zero. Another area with a decent 
drop will be across parts of northeast MO into west central IL, 
again coincident with snow cover. This area however will see warm 
advection and clouds overnight keeping mins more in check than the 
frigid south. 


Glass 


Long term: (friday through next thursday) 
issued at 250 PM CST Thu Mar 5 2015 


Friday through this weekend will feature moderating temperatures 
with near average temperatures over the weekend. The prominent 
eastern noam longwave trof will weaken some but west-northwest 
flow will persist. Embedded within this flow will be several 
shortwaves which will bring weak cold fronts through the area 
Saturday afternoon/evening and again Sunday night. Impacts of 
these will be minor and any cooling will be short-lived. 


The real warm-up will commence next week coinciding with a marked 
pattern change. The eastern longwave will shift northeastward and 
migrate into the North Atlantic bringing a northward retreat of 
the polar jet to the vicinity of the U.S./Canadian border. 
Troffing aloft will persist from the Southern Plains into Mexico 
however heights aloft through the nation's midsection will be 
seasonable. This will result in benign/tranquil weather, persistent 
low level southwesterly flow and warm advection and above average 
temperatures Tuesday through Thursday.
