KEY MESSAGES

-Shower and isolated thunderstorm chances today, with the highest chances across the mountains and north of I-80. Slight chance for showers/t-storms on Saturday in the NE foothills, Burney Basin, Lassen NF and adjacent higher terrain. -Trend toward drier and warmer weather end of the weekend into early next week, with Moderate HeatRisk potential.

..Sunday and onward

To close out May, we will see a more zonal upper level air pattern, which will continue to promote onshore flow in the Delta and allow for our temperatures to become the headline once again. Outside of Delta Breeze influenced areas, temperatures will climb into the mid 90s in the Valley by Monday through Wednesday. Moderate HeatRisk in the Valley returns Monday and becomes more widespread in the Valley floor Tuesday and Wednesday. Another concern moving forward will be the return of low daytime humidity values in the Valley, where by Sunday we could see minimum RH values in the low to mid teens. Still a little too early for headlining any Fire Weather dangers, but we are keeping an eye on the forecast trends.

AVIATION

VFR conditions outside of any showers and thunderstorms that develop around the region today, where MVFR and IFR conditions will develop.
