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, Hard Freeze Warning, Hard Freeze Watch
Mobile & Email Alerts Statement as of 9:24 PM EST on February 11, 2012

... Lake Wind Advisory in effect until 3 am EST Sunday...
... Hard freeze warning remains in effect until 9 am EST Sunday...
... Hard freeze watch remains in effect from late Sunday night
through Monday morning...

The National Weather Service in Jacksonville has issued a lake
Wind Advisory... which is in effect until 3 am EST Sunday.

* Timing... windy conditions and cold temperatures will funnel
across the area tonight.

* Winds... northwest winds of 20 mph with gusts up to 35 mph will
be possible through 3 am tonight along the coast and near inland
water ways. Winds will decrease to 10 to 15 mph.

* Temperature... low temperatures will be in the mid 20s tonight.
Sub-freezing temperatures are expected for 7 to 9 hours.
Northwest winds of 5 to 10 mph will produce wind chills in the
teens Sunday morning. Low temperatures Sunday night will be in
the mid to upper 20s.

* Impacts... freezing temperatures will kill sensitive vegetation
that is not protected.

Precautionary/preparedness actions...

A hard freeze warning means that temperatures less than
27 degrees are expected for at least 2 hours. Appropriate action
should be taken to ensure tender vegetation and outdoor pets have
adequate protection from the cold temperatures. Young children...
the elderly and the homeless are especially vulnerable to the
cold. Take measures to protect them.

A hard freeze watch means that temperatures less than 27 degrees
are possible for at least 2 hours.

A lake Wind Advisory is issued when sustained winds of 20 to
25 mph or gusts of 30 to 39 mph are expected. Small boats will be
especially prone to capsizing. Boaters in the advisory area
should avoid open water and stay close to shore in wind protected
inlets. High profile vehicles should use extra caution when
traveling as well.
