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.

Lake Wind Advisory
Mobile & Email Alerts Statement as of 2:26 PM EST on February 11, 2012

... Lake Wind Advisory remains in effect until 4 am EST Sunday...

A lake Wind Advisory remains in effect until 4 am EST Sunday.

* Hazards: strong winds.

* Winds: winds northwest 20 to 25 knots. Gusts as high as 35
knots.

* Timing: through early Sunday morning.

* Impacts: strong gusty winds will create hazardous boating
conditions on area lakes.

Precautionary/preparedness actions...

A lake Wind Advisory indicates that winds will cause rough chop
on area lakes. Small boats and personal watercraft will be
especially prone to capsizing.





Special Statement
Mobile & Email Alerts Statement as of 6:01 PM EST on February 11, 2012

... Elevated fire danger Sunday...

Wind is not expected to reach the red flag warning criteria
on Sunday. However... low humidity and low fuel moisture will
result in elevated fire danger. Winds Sunday will be northwest to
west at 10 to 15 mph with gusts near 25 mph. Afternoon relative
humidities will lower to near 15 percent over much of the area.

The South Carolina forestry commission has posted a red flag fire
alert for much of the area. The alert strongly advised postponing
outdoor burning until conditions improve.
