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.

Special Weather Statement
Mobile & Email Alerts Statement as of 3:38 AM CST on February 12, 2012

... Winter weather event likely Monday and Monday night...

Moisture will over spread the region Monday... ahead of an upper
level storm system... forecast to be over western Missouri by
Monday evening. The wintry precipitation may be slow to develop
initially Monday west of the Mississippi River over southeast
Missouri... as the airmass will be very dry across the region.
However by afternoon... wintry precipitation should work its way to
the surface... with the activity spreading east from southeast
Missouri Monday afternoon... to areas east of the Mississippi River
including southern Illinois... southwest Indiana and west Kentucky
late Monday afternoon into Monday evening.

Most of the wintry precipitation is expected to be in the form
of snow. However... mixed wintry precipitation is possible as well
with this event... especially south of the Ohio River... and
over southeast Missouri.

Preliminary indications suggest no less than 1 to 2 inches may
accumulate most areas. Some data suggests higher amounts will
be possible. Given the Prospect for mixed wintry precipitation
and the variance seen in the model data... it is still a bit too
soon to gauge snowfall amounts with much confidence. The latest
data suggests higher precipitation rates will occur south of a
line from Perryville Missouri to Owensboro Kentucky which is also
where the best chance of a wintry mix will occur. The best chance
of any freezing rain will be west of the Mississippi River Monday
evening.

Despite the uncertainties with respect to snow amounts... it does
appear that travel impacts will be possible Monday night. Surface
temperatures... antecedent Road conditions... and precipitation
rates will all play a role in the level of impact. Given the cold
air well established across the region ahead of the approaching
system... accumulation will begin shortly after onset.

So... stay tuned for the latest updates. It is possible either
a watch... warning or advisory may be required for the upcoming
event.
