Short Range Forecast Discussion

403 PM EDT Fri Oct 02 2015

Valid 00Z Sat Oct 03 2015 - 00Z Mon Oct 05 2015

...Heavy rain possible for parts of the Southeast and the Southern
Appalachians...

...Temperatures will be 10 degrees below average from the Northeast to the
Western Ohio Valley/Central Gulf Coast...

A quasi-stationary front along with an upper-level low over the Central Gulf Coast/Southeast will aid in producing rain with embedded thunderstorms from parts of the Central Gulf Coast to the Southeast through Sunday.  In addition, high pressure over Eastern Canada will aid in steaming moisture off the Atlantic into the East Coast producing rain from Southern New England southwestward to the Tennessee Valley/Ohio Valley and southward to the Mid-Atlantic through Sunday.

Meanwhile, moisture from the Gulf of California and the Western Gulf of Mexico will stream northward over the High Plains and in combination with upper-level energy embedded in a deep upper-level trough over the Rockies will aid in producing rain over parts of the Northern/Central High Plains/Rockies through Sunday.  While showers and thunderstorms will develop over part of the Southern Rockies and the Southern High Plains also through Sunday.  Additionally, embedded upper-level energy over the Pacific Northwest will move southward to Southern/Central California by Sunday morning.  The system will produce rain over parts of the Northwest on Friday evening into Saturday morning.  The rain with embedded thunderstorms will develop over parts of the California and the Great Basin Saturday evening into Sunday morning.
