Weather Underground midday recap for Saturday,September 28,2013.
A cold front continued to trek through the central part of the U.S. on
Saturday, while a ridge of high pressure brought pleasant conditions to
the majority of the East Coast.
A slow moving cold front inched into the Pacific Northwest earlier
today, which triggered moderate to heavy rainfall over Washington,
Oregon, and parts of Idaho. As a precautionary measure, flood watches
were issued due to how slow this system was moving. A strong pressure
gradient field associated with this cold front produced strong winds in
the region, especially over the Cascades and part of the Rockies.
Meanwhile to the south, a high pressure system continued to sit over the
four corners states, which ushered warm, dry air into the Great Basin
and Southwest.
Just to the east of the Great Basin, a cold front extended from Texas to
Minnesota. This cold front drove plenty of showers and thunderstorms
through the Midwest, as well as parts of the northern Plains. The
strongest thunderstorms associated with this system affected Texas,
Oklahoma, and Missouri earlier today.
Most of the Eastern Seaboard experienced pleasant weather on Saturday
due to a ridge of high pressure over the Northeast. This system drew a
cool, dry air mass in from Canada, which kept humidity levels low and
mid day temperatures in the 60s and 70s. Florida continued to experience
spotty showers and thunderstorms due to an onshore flow from the
Atlantic. .
