Daily Weather Briefing for Monday, February 20, 2017


Weather Advisories and Warnings Across the USA

Weather Advisories and Warnings Across the USA

NATIONAL OUTLOOK

....Slight risk of severe thunderstorms over parts of the Southern Plains continuing into Monday morning...

...Heavy snow possible for the Sierras, Sawtooth and Wind River/Absaroka Ranges...

...Heavy rain likely for portions of Northern/Central California--possible for the Pacific Northwest coast...

...Heavy rain possible for portions Western/Central Gulf Coast...

Much of the West Coast will remain in an active wet pattern through mid-week as multiple Pacific fronts move through the region. A nearly continuous plume of moisture will be directed toward portions of central and northern California through Tuesday-- resulting in heavy rainfall along the coast and valleys; with mountain snow. Snow and lower elevation rain will also develop over parts of the Northern Intermountain region through Tuesday as the the front pushes out into the High Plains.

Additionally, northern stream upper-level energy associated with the deep upper-level trough over the Rockies will move to the Great Lakes by Tuesday morning. The energy will aid in producing rain over parts of the Northern Plains/Upper Mississippi Valley today and spreading into the Great Lakes/Western Ohio valley by Tuesday morning.

A strong line of thunderstorms developed Sunday evening along and ahead of the eastward-moving cold front through the Southern/Central Plains. The showers and thunderstorms are expected to move east into the Lower/Mid-Mississippi valley by this afternoon, extending northward into the Tennessee valley. Warm Gulf air streaming northward along the front will help maintain higher precipitation for the Gulf states. Heavy rainfall may develop and increase the threat for flash flooding. Please refer to WPC excessive rainfall outlooks for additional information on the risk for heavy rain and flash flooding.



LOCAL OVERVIEW

Warm high pressure will move over the area through the early part of the week, bringing temperatures close to record highs. A cold front will bring a chance for some modest rainfall over the area by mid week, followed by brief drying, before a frontal system arrives next weekend with chances of rain and thunder.
