Dry lightning is forecast for Thursday. Stay alert!
Weather West Mod • 5 minutes ago • edited
ECMWF lightning module is explicitly showing lightning over much of NorCal (including SF Bay Area) overnight Thurs. That’s a pretty strong indicator at this point, especially since all the other models are largely in agreement. It’s looking like most of this activity will be organized as a SW-NE oriented band of elevated showers and thunderstorms that will sweep from west to east, bringing very brief/light showers but perhaps an hour of lightning activity. I doubt anyone in the valley or in coastal areas will see much more than sprinkles (trace to 0.05 inches), but a few spots in the foothills and mountains could locally see 0.1-0.2 inches. Still a considerable risk of dry lightning in many areas north of and along I-80, and even the “wetter” cells will pose a significant fire ignition risk given the extreme dryness of vegetation.
The blue stuff from the south is a dry lightning event Thursday, which would be a nightmare. The green stuff from the west is a wet storm that, if it happens, could dump 1-2 inches in the far north state.
Daniel Swain@Weather_West·NorCal weather set-up for Thu/Fri is reminiscent of previous Sept thunderstorm events. Key ingredients include offshore low pressure system & mid-level subtropical moisture tap. Very light showers possible, but main concern remains dry (or nearly so) lightning. #CAfire#CAwx
