The Weather Man Podcast, I talk about weather!

Powerful low pressure system to produce gusty winds, heavy rain, and
the potential for severe thunderstorms across parts of the Great Lakes,
Ohio Valley, and eastern United States through Friday...
...Lower elevation rain and mountain snow to enter California on
Saturday...
...Well above average temperatures forecast to surge into the
northern/central Plains this weekend...
A large, deepening low pressure system currently over the Ohio/Tennessee
valleys this afternoon will be the driving force behind active weather
throughout the eastern United States until early this weekend. Widespread
shower and thunderstorm activity is forecast to continue through tonight
across the lower Great Lakes, Ohio Valley, Appalachians, Mid-Atlantic, and
Northeast. Rainfall could be heavy enough at times to create instances of
flash flooding over the Ohio Valley and central Appalachians, where a
Slight Risk (level 2/4) of Excessive Rainfall is in effect. Additionally,
severe thunderstorms are possible throughout a similar region and could
contain a few tornadoes, scattered damaging winds, and isolated severe
hail. This severe threat also includes the central Florida Peninsula into
this evening, but thunderstorm activity should drastically diminish across
the eastern U.S. by Friday. Heavy rain will continue to be a hazard on
Friday throughout northern New England due to the combination of rainfall
and recent snowmelt. Flood Watches remain in effect between northern New
Hampshire and central Maine as antecedent conditions support the threat of
flash and river flooding. Wind will be another aspect of this storm worth
monitoring as the large low pressure system develops a strong pressure
gradient. The East Coast can expect strong southerly flow ahead of the
system through early Friday and the potential for coastal flood hazards.
Meanwhile, on the backside of the system gusty northwesterly winds are
expected to impact the Great Lakes and Appalachians on Friday and Saturday.
Unsettled weather will enter California on Saturday as low pressure churns
just off the coast and an associated frontal boundary pushes inland.
Locally heavy rain is possible along coastal regions, with moderate to
heavy snow in the high terrain of the Sierra Nevada. Rainfall is also
expected to expand northward into parts of southern Oregon, but is
anticipated to be mostly beneficial.
After a cooler Thursday throughout the Great Plains underneath high
pressure, much warmer weather is on the way by Saturday. Highs are
expected to surge upwards of 20 to 30 degrees above average through the
north-central United States. This equates to widespread highs into the 70s
and 80s from the Great Plains and Upper Midwest to the northern Great
Basin.
