The Weather Man Podcast, I talk about weather!

.A Pacific storm system pushing into the West Coast will bring locally
heavy rain near the coast, and heavy high elevation snowfall into the
Intermountain West over the next couple of days...
Hard hitting storm system to produce accumulating snowfall across the
Great Lakes today and into the Interior Northeast Thursday night and
Friday morning.
.Next round of snow expected to quickly spread from the central Plains
and Ohio Valley on Friday, then into the Central Appalachians and
Mid-Atlantic Friday night into Saturday morning...
A Pacific storm system is ushering in a stream of precipitation into the
West Coast and Intermountain West the next couple days. Meanwhile, a
sufficiently cold air-mass anchored in place by high pressure over
southwest Canada will force a frontal boundary to remain stationary over
the central and northern Rockies through Friday. Coastal areas of the
Pacific Northwest and the valleys of the Intermountain West can expect
periods of rain, while mountain ranges such as the Oregon Cascades, the
Olympics in western Washington, and on east into the heart of the Northern
Rockies witness heavy snow today.
To the east, a low pressure system tracking through the Great Lakes today
is generating showers to the south of its track, while a swath of
moderate-to-heavy snow envelopes southern Wisconsin and northern Michigan.
This storm system is quite progressive, quickly finding itself tracking
over Lake Ontario by Thursday evening. Showers are likely in the central
Appalachians, while periods of snow ensue over the Interior Northeast. By
Thursday night, northwesterly winds escorting in a cold, Canadian air-mass
will rush over the Great Lakes and trigger lake effect snow showers
downwind of Lakes Erie and Ontario Thursday night and linger into the day
on Friday. Snow showers will linger across parts of New England on Friday,
but gradually dissipate as the storm tracks farther into the northwest
Atlantic. In total, over 6 inches of snow is expect in parts of the
Michigan U.P., the northern half of Michigan's Mitten, and across northern
New York. More specifically, the Tug Hill Plateau and neighboring
locations could see over a foot of snow by the time snow concludes Friday
morning. In addition, gusty winds are also an impact from this storm
system, as evident by the Wind Advisories in place over northern Ohio for
today and both western and the Southern Tier of New York between Thursday
afternoon and Friday morning.
By Thursday night, a new wave of low pressure will be taking shape over
the Central Plains with a swath of moderate-to-heavy snow setting up over
northern Nebraska and southern South Dakota. The storm tracks quickly into
the mid-Mississippi river Valley by late Friday morning with periods
anticipated across northern Missouri and central Illinois, while rain
showers and isolated thunderstorms make for a damp day from the ArkLaTex
on east into the Tennessee Valley by Friday afternoon. By Friday night,
the storm will restrengthen as it reaches the Mid-Atlantic with an axis of
moderate-to-heavy snow bringing light snowfall accumulations to the Ohio
Valley Friday evening, then over the northern Mid-Atlantic Friday night
into early Saturday morning. The Potomac Highlands of West Virginia and
Allegheny Mountains from western Maryland to south-central Pennsylvania
have the best chances of seeing snowfall totals surpass 4 inches Friday
night, but anywhere from 1-3" of snow is possible from the mid-Mississippi
Valley on Friday and the Ohio Valley Friday evening, to the DC/Baltimore
metro areas on north to the Philadelphia metro area early Saturday
morning. Some hazardous travel is possible in portions of these regions,
particularly on untreated roads Friday night into Saturday

Fast moving areas of low pressures to produce widespread accumulating
snows across the Central Plains, Mid Mississippi Valley, Ohio Valley,
Central Appalachians, Mid Atlantic, Northern New York and New England...
Heavy precipitation to move into Northern to Central California on
Saturday.
Heavy rains possible for South Texas...
Below average temperatures to spread southeast from the Northern
Plains.
Active Lake effect snows downwind of the Great Lakes Friday and
Saturday.
Two fast moving areas of low pressure pushing from west to east will be
producing widespread areas of accumulating snows across large portions of
the Lower 48. The lead area of low pressure will be moving eastward
tonight from the eastern Lakes region, across northern NY State and into
New England. This system will produce a brief period of snow, with
accumulations of several inches from northern New York State into portions
of central to northern New England. In the wake of this system, cold air
moving across the relatively warm and ice free Great Lakes will support
widespread lake effect snow showers downwind of the Great Lakes. Locally
heavy snowfall totals possible in the favored lake effect areas across the
Upper Peninsula of Michigan and across portions of north central to
northwest New York State, to the east of Lake Ontario.
This first fast moving area of low pressure will be followed by a second
moving quickly east northeast from the Southern Plains Friday, into the
Tennessee Valley Friday night and off the Mid-Atlantic coast early
Saturday. An area of snow will develop well to the north of the surface
low track, with accumulating snows possible from portions of the Central
Plains. east into the Mid Mississippi Valley, Ohio Valley, Central
Appalachians and Mid-Atlantic. The fast movement of this system will a
detriment to heavy totals, with generally 1 to 3 inches of accumulation
forecast across these areas, with isolated heavier totals possible.
Below average temperatures will be spreading south and southeastward from the
Northern Plains/Upper Mississippi Valley. This will produce a below
average temperature day on Friday across the Northern to Central Plains
and Upper Mississippi Valley, with these below average temperatures
spreading south into the Southern Plains and eastward into the Middle to
Lower Mississippi Valley, Ohio and Tennessee Valleys on Saturday. While
these colder than average temperatures are a departure from recent warmth
across this regions, the cold shot will be short lived with temperatures
warming from west to east late in the weekend and into next week.
The current stormy pattern across the eastern Pacific will be pressing
eastward on Friday into Saturday, with heavy precipitation pushing back
into Northern to Central California on Saturday. This precipitation is
the beginning of a wetter pattern for California, with additional heavy
precipitation likely for much of California for the beginning of next
week. The first round of heavy precipitation does have the potential to
produce isolated flash flooding across the central to northern California
coastal regions. The additional heavy rains slated for early next week
will also pose a flash flood threat, with this threat pushing farther to
the south into central to southern California.
An expanding area of rain also likely to develop Thursday night/early
Friday morning across South Texas, persisting into the day on Saturday.
This rainfall will also push east northeastward Friday into Saturday along
the northern Gulf coast and into North Florida. The heaviest totals
expected for South Texas where rainfall accumulations of 1 to 3 inches are
possible.

Thunderstorms to be most active across the High Plains into portions of
the Lower Mississippi Valley into parts of the Southeast...
...Hot weather to begin returning to parts of the West early this week...
The same cold front that was associated with severe thunderstorms and
areas of flash flooding from eastern Colorado into southern Missouri on
Saturday will continue to slowly move south through Monday night before
stalling near the Gulf Coast. Low level convergence near the front and a
region of anomalous moisture extending from the Southeast into the
southern Plains and northward into the northern High Plains will help
support numerous showers and thunderstorms over the next couple of days. A
few of the storms will be capable of becoming severe and/or producing
flash flooding as highlighted by Marginal and Slight Risks of severe
thunderstorms and Excessive Rainfall generated by the Storm Prediction
Center and Weather Prediction Center. Temperatures will be pleasantly cool
north of the front, with high temperature departures expected to be 10-20
degrees below average across the southern High Plains and Great Lakes
region on Monday. Temperatures will moderate on Tuesday but remain below
average from Texas/Oklahoma into the middle Mississippi Valley, Northeast
and Mid-Atlantic region. Cloud cover from scattered showers and embedded
thunderstorms will help to keep temperatures down for parts of the Great
Lakes and Northeast today, but a drier trend is likely through Tuesday for
these areas.
An upper level trough across the western U.S. will be preceded by a weak
cold front at the surface which will move eastward through Tuesday. Severe
thunderstorms will be possible from eastern Wyoming into adjacent portions
of South Dakota and western Nebraska on Monday as the cold front moves
into the Great Plains. The cold front will not make much southern progress
across the western U.S. however, and a shift toward zonal flow in the
mid-levels of the atmosphere will be accompanied by warming temperatures
through mid-week for the West. High temperatures are expected to reach
dangerously hot levels for portions of the Sacramento and San Joaquin
Valley in California as well as southern Nevada into southern Arizona.
Excessive Heat Watches have been posted for these regions in anticipation
of the expanding heat early this week with forecast departures ranging
from 10 to 20 degrees above average on Tuesday.
