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.

... An Arctic blast will drop wind chills into the single numbers
late tonight and Sunday morning...

Evening winds have been frequently gusting to 30 to 40 mph and as
high as around 50 mph along the Cape Fear coast. Winds will begin to
slowly diminish after midnight.

Falling temperatures will combine with the wind to make it feel as
if it were in the single numbers to around 10 degrees at times late
tonight and Sunday morning. The actual temperature will drop to 20
to 25 degrees overnight.

Not much of a temperature recovery is expected on Sunday. The
Mercury will struggle to reach above 40 degrees and for much of
the day it will feel as if it is below freezing. The incoming air
mass will also be very dry with afternoon relative humidity around
20 percent.

Exposed plumbing will be susceptible to freezing and preventative
measures are suggested to prevent damage.

... Enhanced fire weather danger through Sunday...

Gusty winds along with critical relative humidity will result in
an enhanced fire weather danger through Sunday. Winds will
increase tonight in the wake of an Arctic cold front and the
relative humidity will drop below critical thresholds during
Sunday. The last weather system failed to provide any significant
rainfall to the region... thus fuels are dry.

For these reasons... a significant fire growth potential exists
through Sunday. Small fires could quickly grow out of control and
any type of burning is discouraged.

Winds will gradually diminish during Sunday afternoon... and light
winds will prevail by Monday. However... low relative humidity will
persist through Monday given the dry Arctic air-mass that will be
in place over the area.
