The National Weather Service in Saint Louis has issued an Excessive Heat Warning, which is in effect from noon today to 8 PM CDT Monday. The Heat Advisory is no longer in effect. * TIMING...A dangerous combination of heat and humidity will overspread the region beginning this afternoon and continue at least through early Monday evening. Little relief from the heat and humidity is expected during the night. * HEAT INDEX VALUES...Up to around 107 due to temperatures in the mid to upper 90s, and dewpoints in the lower 70s. * IMPACTS...The combination of hot temperatures and high humidity will likely lead to an increased risk of heat- related stress and illness. The very young, the elderly, those without air conditioning, and those participating in strenuous outdoor activities will be the most susceptible. Also, car interiors can reach lethal temperatures in a matter of minutes. PRECAUTIONARY/PREPAREDNESS ACTIONS... An Excessive Heat Warning means that a prolonged period of dangerously hot temperatures and high humidity will occur. In addition, nighttime conditions will remain warm and muggy providing little chance for relief. This combination will create a dangerous situation in which heat-related illnesses are likely, especially for those living in un-air conditioned homes or apartments. People in the Warning area are advised to avoid poorly ventilated areas and prolonged work in the sun. Use air conditioning in your house or apartment if it is working correctly. If you do not have air conditioning, keep your house or apartment well ventilated with fans, and try to spend some time in an air conditioned environment to give your body a break from the heat. Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to the early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency, call 9-1-1 immediately. Where's baby? Look before you lock! Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes. People in the Saint Louis Metropolitan Area can get information about cooling centers or energy assistance related to the excessive heat by calling the United Way of Greater Saint Louis at 800-427-4626, or if calling from a land line phone dial 2-1-1. You can also call Cool Down Saint Louis at 314-241-7668. && $$ ILZ102-MOZ065-152200- /O.NEW.KLSX.EH.W.0001.180615T1700Z-180619T0100Z/ Jefferson MO-Monroe IL- 353 AM CDT Fri Jun 15 2018 ...EXCESSIVE HEAT WARNING IN EFFECT FROM NOON TODAY TO 8 PM CDT MONDAY...

Area Forecast Discussion
National Weather Service Saint Louis MO
353 AM CDT Fri Jun 15 2018
.SHORT TERM... (Through Late Tonight)
Issued at 353 AM CDT Fri Jun 15 2018
Isolated SHRA/TSRA had developed early this morning near an
elevated warm frontal boundary which was draped across central IL.
These cells were slowly drifting southward into southwest IL and
should continue to percolate into the mid-morning hours.
An upper ridge will remain across the region today and tonight. At
the surface, a low pressure center was located across the northern
plains early this morning, and a warm front extended southeastward
from the surface low through MN/IA/IL and into KY/TN. The warm front
is expected to quickly lift northeastward this morning, and a
hot/humid air mass will then spread across the region. Isolated
SHRA/TSRA will be possible across most of the area during peak
heating.
Attention then turns to the hot/humid conditions for today. With air
temperatures in the low/mid 90s and dew points in the 70s, peak heat
index values of around 100-105 degrees are expected across most of
the area today. The warmest values (near 105) are expected in and
near the St. Louis metropolitan area. Hot/humid conditions will
persist for the next few days (see the long term forecast discussion
below). Due to the duration of these oppressively hot/humid
conditions, the Heat Advisory in the St. Louis metropolitan area has
been upgraded to an Excessive Heat Warning and a separate Heat
Advisory has been issued for all but the southern section of the
CWA.

.LONG TERM... (Saturday through Thursday)
Issued at 353 AM CDT Fri Jun 15 2018
This period can be summarized with dangerous heat and humidity
ongoing thru Monday with minimal chances for rain, with a slightly
cooler period from Tuesday on with higher chances for rain.
The first significant wave of dangerous heat and humidity is
expected to be ongoing on Saturday and continue into at least Monday
now. An upper level RIDGE will be overhead at the start of the
period and is expected to dominate our region into Monday, with the
latest model solutions strengthening the position of the RIDGE into
early next week. This will correspond to any frontal boundaries
remaining well to our north with a steady south to southwest flow at
the surface. Daytime max temperatures are expected to be in the mid
to upper 90s, with the highest temperatures expected in the typical
heat island of the Saint Louis metro area and with the hottest days
on Saturday and Sunday where the upper RIDGE will be most dominant.
Dewpoints in the lower 70s for much of the region will yield max
heat index values around 105F each day in the Saint Louis metro
area, tapering to around 100F for other areas. Based on this, the
Heat Advisory for the Saint Louis metro area has been extended in
time to early Monday evening for at least 4 days of 105+ daily
peak heat index values, with an expansion to much of the rest of the
forecast area for Friday thru Monday based on at least 4 days of
100+ daily peak heat index values. This places all but the eastern
Ozarks of southeast MO in a Heat Advisory, and upgrades the STL
metro area counties into an Excessive Heat Warning.
There is an increasing trend where the upper RIDGE may continue to
hang on deeper into next week and keep the cold front locked up to
our north.
As it stands now, the RIDGE is still expected to weaken--just a day
later on Tuesday--which should allow the surface cold front to our
north to edge into our area, increasing rain chances and dropping
max temps into the upper 80s and lower 90s, which is still slightly
above average. This trend looks to continue to the end of the
forecast period.

.AVIATION... (For the 06z TAFs through 06z Friday Night)
Issued at 1232 AM CDT Fri Jun 15 2018
Mainly dry and VFR conditions are expected during the period. Only
exceptions will be late Friday afternoon and early evening when
isolated thunderstorms may develop across eastern Missouri and
southwest Illinois which may affect the St. Louis area terminals.
Confidence is too low to include in the terminal at this time,
but any thunderstorm could bring brief MVFR or IFR ceilings and
visibilities. Otherwise, winds will be mainly out of the south
during the period.
SPECIFICS FOR KSTL:
Mainly dry and VFR conditions are expected the next 30 hours with
south winds. There is a slight chance of thunderstorms late Friday
afternoon and evening, but confidence is too low to include in
the terminal at this time. Any thunderstorm could bring brief
MVFR or IFR ceilings and visibilities.
