Primary concern for this afternoon will be scattered shower and thunderstorm activity moving in from the southwest. Hires guidance highlights 1600 to 2000 local time for the greatest coverage of convective activity, but some development prior to this time can`t be ruled out with destabilization from daytime heating. Erratic wind gusts and isolated lightning strikes are expected to be the most problematic hazards. Although this activity diminishes some tonight, an unstable southwesterly flow aloft will maintain at least slight chances for a few showers or storms during the overnight hours. A Pacific cold front brings a more robust brand of showers and thunderstorms Thursday morning through early afternoon, some storms will be strong to severe with strong winds, hail, and heavy rain in addition to lightning. .REST OF TODAY...
