A winter storm emerging from the Rockies is forecast to bring rain, snow and ice to a large part of the U.S., the National Weather Service said Friday, bringing below freezing temperatures with it ...
Weather radar loop showing intense snow bands (lighter color) due to CSI ahead of a warm front.. Conditional symmetric instability, or CSI, is a form of convective instability in a fluid subject to temperature differences in a uniform rotation frame of reference while it is thermally stable in the vertical and dynamically in the horizontal (inertial stability).
They were compared to their surroundings in order to determine whether these target points were weather holes or the opposite, hot spots. A determination was made by measuring and comparing the convective echoes of the target points with the surrounding area. Only one target was classified as a weather hole, and one was classified as a hot spot.
Turkeys don’t cause a lot of damage, but in the late summer, fall, and winter, they flock together, with up to 20 to 30 turkeys in a group. Turkeys may scratch up newly-seeded lawns, landscaped ...

Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
That means arctic air is blasting over the US, while pressure changes and the motion of the polar vortex whip up high winds and create a perfect recipe for wintry weather.
Vertical cross-section through a supercell showing the BWER. The bounded weak echo region, also known as a BWER or a vault, is a radar signature within a thunderstorm characterized by a local minimum in radar reflectivity at low levels which extends upward into, and is surrounded by higher reflectivities aloft, forming a kind of dome of weak echoes.
