Weather Underground midday recap for Sunday,September 29,2013.
A strong cold front boundary ushered heavy rain and strong winds into
the Pacific Northwest on Sunday, while clear, dry conditions persisted
along the Eastern Seaboard.
Flash flood warnings were issued in northern California, Oregon, and
Washington as a slow moving cold front boundary inched across the
region. Strong winds also accompanied the cold front, especially along
mountain slopes. Heavy snow fell in the Cascades and northern Rockies,
particularly along Western facing slopes. The Southwest, as well as the
majority of the Great Basin, avoided precipitation earlier today as a
ridge of high pressure drew warm, dry conditions into the area. Palm
Springs, California recorded a mid day high of 90 degrees, which was the
warmest spot in the nation on Sunday.
Just to the east of the Great Basin, a cold front boundary stretched
from Texas to Michigan, and was accompanied by moderate showers and
thunderstorms. The strongest thunderstorms associated with this cold
front boundary moved over eastern Texas and Louisiana, as New Braunfels,
Texas recorded around four inches of rain on Sunday. Spotty
Thunderstorms also impacted parts of Florida, but were a result of an
onshore flow from the Atlantic.
The remainder of the East Coast felt the effects of a high pressure
system over the Mid-Atlantic states. Temperatures remained in the 60s
and 70s during the early afternoon, and humidity levels stayed low.
