Forecasters at the National Weather Service office in Reno are warning Lassen county residents to prepare for unusually warm temperatures beginning Tuesday as summer-like high pressure builds over the region.
The first real heat of the summer season for several days in a row could lead to heat health impacts for vulnerable populations and those outdoors in the sun for extended periods of time.
Prepare now to do outdoor activities next week in the morning and have a cool place to go during the afternoons.
High temperatures 20 degrees above normal could approach daily records. Peak heat is projected for Wednesday and Thursday.
Valleys will reach well into the 90s with mountain communities well into the 80s. Friday could have similar heat; however, more clouds and thunderstorms could limit how hot it gets.
Thunderstorms will become more common starting Wednesday, especially over the high terrain. Be prepared for lightning, downpours, sudden temperature drops, hail, and strong outflow winds. Storms could impact outdoor recreation along with any outdoor pandemic response facilities.
