Weather Underground Forecast for Sunday, February 12, 2012.

The East dries out on Sunday, but wet weather continues moving through the West. A trough of low pressure advances eastward over the Great Basin and Central Rockies, producing moderate snow showers over Utah and Colorado. Winter weather advisories have been issued for parts of western Colorado as snowfall accumulations may reach from 6 to 8 inches by Sunday evening. Most of Utah, western Wyoming, and northern New Mexico should see lighter snow showers with accumulation around 1 to 2 inches. The tail end of this trough will extend into western Texas, bringing snow and freezing rain showers into northwestern Texas. Precipitation from this system will move into the Texas Panhandle late Sunday into Monday morning. Winter storm warnings have been issued for the region as 3 to 5 inches of snow are possible, with ice accumulations from 0.10 to 0.30 inches by Sunday evening. This will cause dangerous roads and travel conditions.

Meanwhile, another trough of low pressure and associated cold front approach the West Coast on Sunday. This system will reach the coasts of the Pacific Northwest and northern California in the afternoon and evening hours, bringing more rain showers. Temperatures will remain cool over most of the West Coast as this system pushes clouds and moisture onshore.

In the East, a strong ridge of high pressure allows for dry, sunny, and cool weather to persist. This system creates strong flow from the north, pushing cold air into the Plains and Eastern Valleys. Expect highs to range in the 20s in the Midwest, while the Ohio River Valley and Tennessee Valleys will see highs in the 30s. Freeze advisories have been issued for the Gulf states as low temperatures will drop into the 20s Sunday night. Dangerous fire conditions spread over the Southeastern states due to high pressure creating a very dry airmas with strong winds.

Mobile & Email Alerts Statement as of 3:08 AM EST on February 12, 2012

... Fire Danger Statement...

Low fuel moisture combined with northwest winds of 10 to 15 mph
with gusts near 20 mph and critically low humidity of 15 to 20
percent will result in an enhanced fire danger across southeast
South Carolina and southeast Georgia today.

Precautionary/preparedness actions...

Please refer to your local burn permitting authorities on whether
you can burn Sunday. If you do burn... you are advised to use extreme
caution.






Public Information Statement
Mobile & Email Alerts Statement as of 8:25 am EST on February 12, 2012

... Cold weather preparedness and safety information...

The key to any preparedness and safety actions is to act well
before any problems occur.

Try to stay inside as much as possible. If you must be outside...
dress appropriately for the cold weather. Dress in layered
clothing... with a hat... scarf... and mittens or gloves.

Protecting pipes from freezing...

Remove and drain outdoor hoses and store indoors. If possible...
close any valves that supply outdoor hose bibs... then open and
drain remaining water from outdoor values. Check any other areas
where pipes could be exposed to the cold... and cover or insulate
those pipes if possible. Let at least one faucet drip inside your
home tonight... which will help prevent ice from building up in
the pipes. Open up the Cabinet doors underneath all sinks to
allow for warmer air to circulate inside.

Other areas around the home...

Keep garage doors closed... especially if there are water supply
lines located in the garage. Keep your thermostat set at the same
temperature during the day and the night... helping to maintain
sufficiently warm temperatures inside the home... and lowering the
threat for pipes to freeze. If you are going away... keep your
thermostat set no lower than 55 degrees.

Plants and pets...

If there are any plants outside that will be susceptible to the
cold weather... we suggest covering them or if possible bringing
them inside.

Do not Forget about your pets. If you can... bring them inside at
night. If this is not possible... make sure they will have plenty
of warmth such as blankets or other coverings to remain warm.
Ensure that they have plenty of unfrozen drinking water.

Those susceptible to the cold...

Check on the elderly and others such as Young children and those
with illnesses that may be more susceptible to very cold
temperatures. Make sure they have adequate heating and shelter.

Portable heating devices...

If using heating devices such as an electric space heater... make
sure it is is good working order... is never left unattended... and
is not located near any flammable materials. Avoid using any
heating devices that use an open flame or combustible materials.

For additional cold weather safety and preparedness information...
please visit the National Weather Service in Charleston at...
www.Weather.Gov/chs.
