Model ensembles trending even wetter for NorCal between now & end of Oct. I'm personally skeptical that *this* much will actually fall, but I'm increasingly convinced of significant rain/mountain snow that will likely be fire-season ending from about I-80 northward. #CAwx #CAfire https://t.co/QFGsJxT9fs

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

Major CA heatwave still appears to be in the cards 5-7 days from now. Another prolonged period of very hot conditions is possible across interior, and coastal spots will probably get hotter than last PacNW-focused event. Still not clear exactly hot hot it may get. #CAwx #CAfire

Models once again hinting at potential for major heatwave about a week from now. Operational runs hinting at what could be rather intense event, with June monthly temperatures records threatened, although ensembles more muted. Still, very strong heat signal for mid-June... #CAwx

PSA: Relatively low-latitude, even sub-tropical, locations in central & eastern portions (but less frequently western portions) of continents can occasionally experience severe winter cold spells--like Texas is currently enduring. But how, & why this longitudinal asymmetry?(1/17)

More record high temperatures possible over the next few days across California. With ensembles projecting zero precipitation in San Francisco and Sacramento through Saturday evening, February 2020 now virtually certain to be driest in history across most of NorCal. #CAwx

Well above average, spring-like temperatures expected for much of the coming week across nearly all of California. Some spots, even in the north, will make it well into the 70s to around 80F. Next chance of rain/mountain snow will be around March 1st, but looks transient. #CAwx

Another big heatwave headed for California next week. Get ready for a potentially very long-duration stretch of very hot conditions nearly essentially statewide. Not quite as hot as SoCal record breaker 2 weeks ago, but very impressive nonetheless. #CAwx #CAheat
