The Weather Man Podcast, I talk about weather!

Unsettled weather continues across the West Sunday with some locally
heavy rainfall and isolated flood risk for Southern California and
Arizona...
Risk for severe weather and flash flooding from the Middle Mississippi
Valley southwestward into the Southern Plains on Monday.
Showers and storms with some severe weather and flash flooding threat
for portions of the Midwest/Ohio Valley Sunday into Monday.
Unsettled weather will continue across the West as a deep upper-trough and
accompanying surface frontal system push inland across the region.
Widespread showers and storms will continue this evening in Southern
California but should decrease in coverage/intensity as the cold front
pushes eastward, reducing the influx of moisture. A Slight Risk of
Excessive Rainfall (level 2/4) remains in effect for the LA Basin/eastern
Transverse Ranges south through the Peninsular Ranges through Sunday
morning where the additional rainfall may lead to some instances of
flooding given the wet antecedent conditions from the prior days'
rainfall. Some more isolated instances may also continue into the day
Sunday before the rain fully tapers off. Additional locally heavy rainfall
with an isolated flood risk will stretch into the Lower Colorado River
Valley through Sunday morning, and into portions of southern Arizona
Sunday. Otherwise, lower elevation rain showers/thunderstorms and higher
elevation mountain snow are expected more broadly across the Great Basin,
Southwest, and Rockies Sunday. Locally heavy snow is forecast for some of
the regional mountain ranges, particularly from the Sierra eastward
through the Great Basin/Four Corners region into the central Rockies, with
some Winter Storm Warnings/Winter Weather Advisories in place. Some snow
may mix in at lower elevations in the Great Basin and into the Rockies as
temperatures remain cooler following a cold front passage, though any
accumulations should remain light. Precipiation chances should come down
through the day Monday as the frontal system pushes eastward into the
Plains.
As the upper-trough shifts east, lee cyclogenesis will help to
strengthen/consolidate an area of low pressure over the Central Plains
along a wavy, quasi-stationary boundary extending eastward through the
Middle-Mississippi Valley and into the Mid-Atlantic. This boundary will
become the focus for areas of widespread showers and thunderstorms over
the next couple of days. The Central/Southern Plains will remain mostly
dry Sunday, with precipitation limited to a wintry mix to the north of the
boundary over portions of the Northern Plains in the presence of moist,
upslope flow. Some light to moderate snow accumulations are expected,
particularly in vicinity of the Black Hills. Then, on Monday, the focus
shifts southeastward to the frontal boundary through the Middle
Mississippi Valley southwestward along a dry line and approaching cold
front through the Southern Plains. Increasing moisture/buoyancy as well as
strengthening deep and low-level shear will lead to the threat of numerous
thunderstorms with the potential for severe weather. The Storm Prediction
Center has outlined an Enhanced Risk (level 3/5) from central Missouri
southwestward into eastern Oklahoma where an increasing potential for very
large hail, damaging winds, and tornadoes exists. A broader Slight Risk
extends southward into north Texas. In addition, the expectation for
repeated storms with increasing coverage as flow runs parallel to the
approaching cold front has prompted an overlapping Slight Risk of
Excessive Rainfall from central Missouri southwestward into northeastern
Oklahoma.
