...Thunderstorms expected across the Southeast and Carolinas...
...Cooler temperatures will continue to prevail the eastern U.S. with
warmer weather across the West and Plains...
An upper low continues to dig across the Southeast while a strong cold
front will move across the Southeast, Florida, and the Carolinas. Copious
amounts of moisture will stream across northern Florida and southern
Georgia while the cold front will act as a focal point to set off
convection. Consequently, heavy rain will impact these regions as the
cold front pushes south and east. By early Thursday morning, heavy
rainfall will shift toward central Florida ahead of the cold front and
slowly moves toward South Florida. As the front stalls on Friday morning
in South Florida, showers and thunderstorms will linger in this region and
the Florida Keys.
The primary low for the aforementioned cold front will progress northeast
in the Ohio Valley and will approach the Mid-Atlantic and Northeast by
tonight. Precipitation will increase in these areas by late tonight and
continue for Thursday. Another low will form in Delmarva on Thursday
morning and take over while sliding along the New England coast. This
will cause heavy rainfall throughout Thursday and Friday throughout the
New England area; expect the heavier rainfall to taper off beginning
Friday night. Overall, flash flooding will be a concern along the central
and southern Appalachians as orographics will enhance precipitation across
Another upper level low will move across the Intermountain West and toward
the Plains tonight and into Thursday. A surface front will move across
the Intermountain West; however, moisture will be limited so not much
precipitation is expected. Once the front moves into the Plains, showers
will move along and ahead of the boundary. Precipitation will begin to
increase along the central Plains and into the central Rockies on Thursday
and will linger across the West as the front stalls from the Central Basin
to the Front Range of Colorado. The heaviest rainfall is expected to fall
along northwest Kansas into the beginning of the weekend.
Cooler temperatures will continue across the East Coast with warmer
temperatures in the western U.S. By Thursday, cooler temperatures are
expected in the Intermoutain West/Central Basin as precipitation increases
in this area and warmer temperatures will shift to the southern Plains.
