Weather Underground midday recap for Tuesday, September 17, 2013.
The remnants of Hurricane Ingrid continued to move through eastern
Mexico on Tuesday, causing showers and thunderstorms to affect parts of
southern Texas. Cool weather impacted the Northeast through the first
half of the day as frost advisories were issued. Out West, the Pacific
Northwest experienced rain along the coast, while the northern Rockies
were impacted by showers and thunderstorms.
A high pressure system situated in the Northeast caused a cool air to be
drawn in from Canada. Temperatures remained below average for this time
of year, as Mount Washington recorded a low temperature of 19 degrees
this morning. The same high pressure system also drew warm air from the
Gulf Coast into the Midwest as temperatures remained warm and
thunderstorms rolled through the region. Southern Florida experienced
thunderstorms as a result of a cold front passage, while the remnants of
Ingrid caused spotty showers and thunderstorms to impact parts of
southern Texas.
The Northeast experienced showers along the coast as an upper level
trough began to emerge in the region. Slightly farther east, a cold
front brought showers and thunderstorms to the northern Rockies, while
the majority of the Great Basin remained dry. A slight chance of severe
weather lingered around the northern Rockies as a result of an unstable
air mass. The Southwest continued to sit under a dominant high pressure
system, which brought warm and dry conditions to the area on Tuesday. .
