Weather Summary

Weather Underground Forecast for Tuesday, February 14, 2012. Valentine's Day will be greeted by a storm that will begin the day in the Mississippi Valley before moving eastward into the eastern third of the country. In the colder air to the north, snow is expected to fall through the Ohio Valley before moving into the Northeast in the evening. The warmer air to the north will only allow areas of light to moderate rain to form from Louisiana through the Carolinas. By the end of the day, much of the precipitation from this storm will be off the eastern seaboard, leaving warmer air in the Southern Plains and much colder air in the Northern Plains and Upper Midwest.

In the West, a storm will track through the Great Basin before slamming into the Rockies, where it will produce much needed high elevation snow. This will not be a tremendous snow producer, but several inches of the white stuff is expected.

Late in the day, a Pacific storm will make its approach to the West Coast. As the storm moves inland, it will instigate rain and high elevation snow in Washington and Oregon. This storm will be the next rain producer for California on Wednesday.

The Northeast will rise in to the 30s and 40s, while the Southeast will see temperatures in the 50s, 60s, and 70s. The Northern Plains will rise into the 30s and 40s, while the Northwest will see temperatures in the 30s and 40s.

... NWS Sterling radar klwx dual-polarization upgrade ahead of
schedule...

The Sterling Virginia WSR-88D radar /klwx/ will be down for an
upgrade to dual-polarization technology /dual-pol/ starting this
Friday - February 17th... through Friday - February 24th. The
previous schedule was for the installation to occur the last two
weeks of March 2012.

While the radar is down for these upgrades... neighboring WSR-88D
radars that will be utilized are...

Kdox - Dover de
kakq - Wakefield VA
kfcx - Roanoke VA
krlx - Charleston WV
kpbz - Pittsburgh PA
kctp - State College PA
kdix - Mt Holly NJ

Two of these neighboring radars have already been upgraded to dual-
polarization technology:

Kpbz - Pittsburgh PA
kdix - Mt Holly NJ

To supplement the data suite... we also will use the following FAA
terminal Doppler weather radars /tdwrs/ during the installation
period...

Tbwi - Baltimore/Washington
tadw - Andrews AFB
tdca - Reagan National
tiad - Dulles

Dual-pol technology offers a new set of tools to better
differentiate between rain... snow... hail... mixed precipitation and
non-precipitation echoes. This upgrade provides forecasters with
better rainfall accumulation estimates and enhanced information to
more effectively forecast severe storms and winter weather.

Dual-pol utilizes a polarmetric beam that detects differences
between the vertical and horizontal orientation of atmospheric
targets. Conventional radar only detects the horizontal orientation.

To learn more about the dual polarization upgrade... and for access
to dual-pol training for non-NWS meteorologists... please visit...
