...Heavy snow possible for the Cascades, Sierras, Sawtooths, the Mogollon
Rim and Central Rockies...
...Strong thunderstorms and heavy rain possible over eastern Texas and
lower Mississippi valley...
...Heavy rain possible for portions of northern and central California...
Surface low and associated front will spin up near the Southeast Coast
today as an upper-level low propagates eastward -- resulting in showers
and a few thunderstorms for Florida and the Southeast Coast.
Rain will also develop over parts of the Southern Ohio and Tennessee
valleys along with parts of the Central/Southern Appalachian this morning
and will move into parts of the Mid-Atlantic/Central Appalachians this
afternoon before dissipating.
The system that brought widespread heavy precipitation to California and
portions of the Southwest will continue to weaken as it tracks eastward
into the Central/Southern High Plains today and into Monday. Rain and
higher elevation snow is forecast for parts of California, the Great Basin
and Southwest ending over most of California this morning and will expand
into the Central/Southern Plains, waning by Monday. Farther north,
multiple waves embedded within the upper-level low will move into the
Northwest and Intermountain West/Northern Rockies early and will aid in
producing rain and higher elevation snow from the Coast into parts of the
Northern Rockies. Heavy snow will be possible for some of the higher
elevations of the Cascades, Sierras, Sawtooths, the Mogollon Rim and
Central Rockies. A plume of moisture will stream into California bringing
another round of heavy rainfall to portions of central California. Rain
and higher elevation snow will develop over parts of Central/Southern
California.
As the upper-level low moves eastward, circulation around the low will aid
in streaming moisture into Eastern Texas that will move northward to the
Middle Mississippi Valley by Monday. Showers and thunderstorms will begin
to develop over parts of the Western Gulf Coast and will expand northward
into the central U.S. this afternoon. Some of the storms over eastern
Texas may become severe this afternoon. Refer to the Storm Prediction
Center webpage for addition information on the threat for severe weather.
