Weather Summary

Weather Underground midday recap for Saturday, February 11, 2012.

Cold air poured into the Plains on Saturday, while snow showers developed in parts of the Northeast. A strong low pressure system that brought heavy rain to the Southern Plains and Southeast has advanced eastward and off the East Coast into the Atlantic Ocean. However, counter-clockwise flow around this system continued to push moisture into the Northeast, Great Lakes, and Ohio River Valley. In addition to cool air over the region, this allowed for snow showers to develop across Michigan and the Ohio River Valley. Snowfall accumulations ranged from 1 to 3 inches in most areas, with up to 5 inches at higher elevations of the Central Appalachians. Coastal regions remained slightly warmer, which maintained light rain showers from southern Maine through Virginia.

Behind this system, a dominant ridge of high pressure continued to build over the Plains. This system started to stretch eastward over the Mississippi Valley. Flow around this system pulled cold air in from central Canada and kept seasonable cool temperatures over the Central US. High temperatures only reached into the 30s in parts of northern Texas, while the Central and Northern Plains saw highs in the teens, with overnight lows in the negative teens.

Out West, cool conditions persisted with areas of wet weather as a trough of low pressure moved over the Pacific Northwest and into the Intermountain West and Great Basin. Rainfall totals and high elevation snow accumulation remained light. A few light rain showers extended into California as moist onshore flow persisted.

Special Weather Statement
Mobile & Email Alerts Statement as of 12:11 PM CST on February 11, 2012

... A wintry mix still on tap for Sunday night into Monday...

A mix of wintry precipitation is expected across eastern Oklahoma
and northwest Arkansas late Sunday night... continuing into the day
Monday. Given the timing of the precipitation... some impacts are
expected for the Monday morning commute.

A fast moving storm system will move out of the Desert Southwest
late this weekend... resulting in precipitation development across
the Southern Plains. With cold air already in place... the
precipitation will likely begin as snow across eastern Oklahoma
late Sunday night... spreading into northwest Arkansas Monday
morning.

As the storm system moves closer to and over the area... temperatures
aloft will increase from southwest to northeast... which will cause
the snow to transition to sleet and/or freezing rain over a good
portion of the area on Monday. The heavier precipitation will be
ending from west to east starting around midday Monday... with
lingering areas of drizzle or freezing drizzle into Monday night.

The highest snow accumulations will likely occur near the Kansas
and Missouri borders... as well as in the higher terrain areas of
northwest Arkansas. At this time... it appears that 1 to 4 inches of
snow and sleet accumulation is likely with locally higher amounts
possible. There is also the potential for some minor ice
accumulations to the south of the heavier snow band. Prolonged power
outages or similar major ice impacts are not expected.

Persons should continue to monitor the latest forecasts as snow
and ice amounts continue to be refined through the weekend. A
Winter Storm Watch may be needed for some areas late Sunday night
into Monday.
