Weather Summary
Kari Kiefer
Weather Underground midday recap for Tuesday, February 14, 2012.

Multiple areas of wet weather developed over most of the nation on Tuesday. In the East, a weak trough of low pressure brought snow, freezing rain, and rain showers to the Upper Ohio River Valley, Central and Northern Appalachians, and the Northeast. Snowfall accumulation over the region remained light and varied around an inch in most places. Meanwhile, a cold front extended south from this system and extended over the Southeast. This pulled in moisture and energy from the Gulf of Mexico, and triggered showers and thunderstorms over the Gulf coast. Heaviest rainfall accumulation reached up to 0.96 inches in Key West, Florida.

Out West, light snow showers developed across most of the Rockies as a trough moved in from the West Coast. This brought light snow to the Northern and Central Rockies, with winter weather advisories issued for parts of Utah, Colorado, and northern New Mexico. The southern side of this system brought a messy combination of rain and snow to Arizona and New Mexico. Heaviest snowfall accumulation ranged from 3 to 5 inches in parts of Utah. Further West, a low pressure system offshore pushed a cold front into the Pacific Northwest, which produced more rain and high elevation snow showers.

... 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 dual-pol training for non-NWS meteorologists... please visit...
