Daily Weather Briefing for Saturday, March 25, 2017

NATIONAL OVERVIEW

...There is a slight risk of severe thunderstorm over parts of the Lower/Middle Mississippi Valley/Central Gulf Coast/Tennessee Valley...

...Heavy rain possible over parts of the Tennessee Valley/Southern Appalachians...

...Rain/freezing rain possible over parts of the Upper Great Lakes and the Northeast...

An upper-level low over the Central/Southern Plains and Middle/Lower Mississippi Valley will move northeastward to parts of the Ohio Valley/Great Lakes while weakening by Sunday. Moisture from the Gulf of Mexico will stream northward into the Ohio Valley and pool along the associated stationary front into the Mid-Atlantic. Showers and thunderstorms will develop along and ahead of the cold front over the Middle/Lower Mississippi Valley that will move eastward to the Eastern Ohio Valley/Eastern Gulf Coast by Sunday. Rain will develop over parts of the Central Plains into the Great Lakes/Ohio Valley and the Northeast through Sunday. The rain will end over parts of the Central Plains by Saturday evening. As the rain moves into parts of the Northeast and Upper Great Lakes, rain/freezing rain will develop over parts of the areas Saturday night into Sunday evening.

Meanwhile, an upper-level trough over the West Coast will move eastward to the Plains by Sunday evening. The system will produce rain and higher elevation snow over parts of the Pacific Northwest/California eastward to parts of the Northern Rockies/Great Basin that will move into parts of the Central/Southern Rockies and the Northern High Plains by Sunday morning. In addition, the rain and higher elevation snow will come to an end over parts of the Pacific Northwest/California into the Northern Rockies/Great Basin overnight Saturday into Sunday morning. By Sunday afternoon, rain and higher elevation snow will begin again over parts of the Pacific Northwest/California into Sunday evening as additional upper-level energy moves onshore over the West.

Additionally, energy in the upper-level trough moving eastward across the Southwest/Southern Rockies will develop low pressure over the Southern High Plains overnight Saturday moving eastward to the Southern Plains by Sunday evening. The system will produce rain and higher elevation snow over parts of the Central Rockies/Central High Plains on Sunday morning. On Sunday afternoon into Sunday evening, showers and thunderstorms will develop over parts of the Southern/Central Plains.

LOCAL OUTLOOK

Moisture will gradually return to the region today around offshore Atlantic high pressure. Meanwhile, a low pressure system will lift from the southern plains to the Midwest and push a band of moisture toward the southern Appalachians. Deep moisture and persistent southwesterly flow will set up over the southeast Sunday through Tuesday with several rounds of showers and thunderstorms likely.
Drier air should return by the middle of next week.
