…Heavy rain and severe weather probable across the Central/Southern
Plains this weekend…
…Mountain snow will spread from the Pacific Northwest into much of the
Intermountain West over the next couple of days…
…Much above average temperatures expected across large portions of the
central to eastern U.S….
A cold front will bring gusty winds and cool temperatures into the
Northeast by tonight and into the weekend. While less record temperatures
are forecast over the next few days across the eastern two-thirds of the
country, widespread above average temperatures are expected across large
portions of the central to eastern U.S. as a strong dome of high pressure
builds across the eastern half of the country. The aforementioned high
pressure system which will build across the Northeast this weekend, will
continue the dry conditions down the Eastern Seaboard for the first few
days of November.
Attention will then focus across the Central and Southern Plains as a
rather significant heavy rain and severe weather event will emerge this
weekend. As moist air from the Gulf of Mexico returns and streams
northward into the Southern Plains behind the high pressure system, a
deepening upper-level trough will move through the western U.S. This
trough will spread more mountain snow across the Intermountain West this
weekend. Southwesterly flow ahead of the trough will then interact with
the returning Gulf moisture over the southern Plains and lift the moisture
over a warm front. It appears that moderate to heavy rain associated with
organized thunderstorms will first develop over the Southern High Plains
tonight. The thunderstorms and heavy rain will then expand northeastward
into the Central Plains through the weekend. A few inches of heavy rain
with locally higher amounts is forecast across the Southern Plains, with
the heaviest rainfall expected across central Oklahoma. Similar to many
areas of the Lower 48, this region is experiencing moderate to extreme
drought conditions. While this round of heavy rain will help alleviate
the drought, the high rainfall rates will also bring an increasing threat
of flash flooding. Please stay abreast of the latest forecast updates on
this upcoming heavy rain/severe weather event across the central to
southern Plains.
