Valid 12Z Fri Nov 01 2024 – 12Z Sun Nov 03 2024…Threat of a heavy rain and severe weather event increasing across the
central to southern Plains throughout the weekend……Mountain snow will overspread from the Pacific Northwest into much of
the Intermountain West over the next couple of days with heavy rain today
near the Pacific Northwest coast……Much above average temperatures expected across large portions of the
central to eastern U.S. with little rain in sight along the East Coast…A trailing cold front in connection with a low pressure system currently
moving east across the Great Lakes toward New England will bring a chance
of rain into the eastern U.S. on this first day of November following an
exceptionally dry October for this part of the country. However, it
appears that the rain will not progress much beyond the Appalachians today
as another day of warm and dry conditions is forecast for the East Coast.
In fact, the warm temperatures into the 70s early this morning have
already challenged high temperature records for November in upstate New
York. In addition, record high morning lows are possible this morning
from the Mid-Atlantic into New England and record high temperatures are
possible Friday afternoon from near New York City to northern Maine. The
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 expected across large
portions of the central to eastern U.S.A high pressure system will build across the Northeast during the weekend
and will sustain 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 be emerging throughout the 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 be moving
through the western U.S. This trough will bring another round of heavy
rain near the coast for Pacific Northwest today before spreading more
mountain snow across the Intermountain West through the 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 rains 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 aleviate the
drought, the high rainfall rates will also bring an increasing threat of
flash flooding. Please keep abreast of the latest forecast updates on
this upcoming heavy rain/severe weather event across the central to
southern Plains.
