Thunderstorms with heavy rain, lightning and small hail are expected Thursday around Puget Sound. The storms could threaten the Seattle region just as fans gather for the matchup at Centurylink Field between the Seahawks and Rams.
The setup for the thunderstorms will be similar to what we've experienced at times over the past few weeks -- chilly air aloft from Alaska increasing atmospheric instability over the region. This instability is a greater-than-normal difference between the temperature near the ground and aloft and allows clouds to bubble higher in the sky. %
When we get those thunderstorms to be tall enough, static electricity charge builds up in the clouds and lightning can be produced.
Small hail will also be a possibility as well as locally gusty winds.
The best chance for lightning and these other threats will be in the mid-afternoon into the early evening hours. The threat will subside after the sun sets at 6:46 p.m.
Fans visiting the game will need to stay weather aware though any issues with lightning, downpours or small hail should be brief in duration if there are any impacts to the stadium area at all.
