The Weather Man Podcast, I talk about weather!

Severe weather threat returns to the northern and central Plains on
Tuesday, followed by severe weather and heavy rain/flash flooding threats
farther down the central Plains on Wednesday...
...More high-elevation snows expected across the Pacific Northwest into
the northern and central Rockies for the next couple of days...
...Warmer than average temperatures across the southern tier states to the
Midwest and Mid-Atlantic but cold and windy across the Northwest...
The weather pattern that keeps sending fast-moving disturbances across the
western U.S. will continue to form new low pressure systems in quick
succession over the mid-section of the country through the next couple of
days. The latest low pressure system that brought severe weather and
flash flood emergencies over eastern Texas, together with widespread cold
rain across the northern U.S., to wet snow near the Canadian border, will
weaken as it tracks northeast across the Great Lakes into southern Canada
on Tuesday. Meanwhile, the heaviest thunderstorms and severe weather
associated with the trailing front had moved off the Louisiana coast.
Less intense showers and thunderstorms are expected to push eastward
across the Mid-South, Tennessee and Ohio Valleys toward the Appalachians
and New England on Tuesday, before becoming more widely scattered along
the Eastern Seaboard into Wednesday morning. Snowfall on the order of
6-12 inches are forecast to accumulate over parts of the Cascades and
northern Rockies increasing to nearly 2 feet over the higher elevations of
Glacier National Park.
As the surge of cold air pushes through the Northwest on Tuesday with the
leading cold front reaches the northern and central Plains, a couple of
low pressure systems are forecast to develop. The low pressure system
that will move across the upper Midwest will bring a threat of severe
thunderstorms across the northern and central Plains ahead of the trailing
cold front on Tuesday. Another low pressure system will develop over the
central Plains on Tuesday, this system will bring a higher threat of
severe weather and more widespread heavy rain threat farther south into
the central Plains later on Wednesday as the system intensifies.
Temperature-wise, fast-moving cold upper troughs propagating through the
Northwest and Northern Plains/Upper Midwest will keep things cooler than
average today. More cold air will push through the Pacific Northwest on
Wednesday. Meanwhile, a warming trend will send afternoon temperatures as
high as the lower 90s for the next couple of afternoons across the central
to southern High Plains. Temperatures will also be well above average
along the East Coast on Tuesday followed by a slight cool down on
Wednesday as a back-door cold front dips south from New England.
