US Hazards for Wednesday, October 12, 2016

US Hazards


Region 1

Instability should build across Region 1 on Wednesday as a result of daytime heating ahead of an approaching cold front. This will allow for a few strong to severe thunderstorms to develop along the front. The greatest threat for severe thunderstorms will be across Arkansas and Missouri; large hail and damaging winds will be the main hazards. Across the other parts of Region 1, damaging winds will be the primary hazard. The threat should decrease into the evening. 


Major Cities in Region: Fayetteville, AR, Springfield, MO, St. Louis, MO, Chicago, IL

Region 1


Excessive Rainfall Possible Thursday for Pacific Northwest

A large low pressure system will move into the Pacific Northwest on Thursday, bringing the risk of excessive rainfall leading to flooding across much of the coastal Pacific Northwest. Plentiful Pacific moisture will move into the region ahead of the system, allowing for widespread and persistent rainfall. Showers will develop along the coast overnight Wednesday and into Thursday and increase in coverage and intensity throughout the day and into the evening. Rainfall accumulations of 2-4 inches will be common within the threat area, with locally higher amounts in excess of 5 inches possible in the higher terrain. Due to the preceding dry season, river flooding is not much of a concern, however, stream and urban flooding will be likely. In addition to the heavy rains, wind gusts up to 50 mph will be possible along the coast and higher terrain Thursday afternoon and evening.

A second area of low pressure will move into the Pacific Northwest on Saturday. This will bring the potential for the risk for heavy and excessive rainfall as the low tracks into British Columbia. Heavy rain will continue into Sunday with rainfall totals of 4-8 inches and isolated higher amounts in excess of 10 inches will be possible. Some stream and urban flooding will be possible.
