National Situation Update: Sunday, June 17, 2007

Homeland Security Threat Level: YELLOW (ELEVATED).

National Weather Summary

West: A fast moving frontal system will produce precipitation from Puget Sound into the northern Rockies of Idaho and Montana.  Behind the front temperatures across the Pacific Northwest will run between 5-10 degrees below average with highs only in the 60s and 70s.  The Southwest will remain very hot with afternoon highs running in the triple digits.

South: The upper-level low over Texas will continue to produce scattered thunderstorms and locally heavy rain for Texas, Oklahoma, Arkansas, and Louisiana.  This low will start to move east tomorrow moving scattered thunderstorms to the southeast.  Rain and thunderstorms are forecast across southern Florida, including the Keys, due to a weak frontal boundary interacting with tropical moisture streaming up from the Caribbean.  Afternoon highs will reach the 90s except where clouds and rain will keep highs in the 70s and 80s.

Northeast: A cold front will produce precipitation across the region during the afternoon and evening hours with the potential for isolated strong storms in New England.  Temperatures will be generally 5-15 degrees above average with warm westerly winds producing highs into the 80s across Maine and much of the Northeast and into the 90s from New York City to the Del-Mar-Va peninsula.

Midwest: A low pressure system moving along a stalled frontal boundary is producing severe thunderstorms from North Dakota to Wisconsin. Highs will range from the mid to upper 80s across much of the Midwest to the 90s in the Ohio River Valley, Iowa and southern Minnesota. (NWS, Media Sources)
