UPDATE at 3:51 p.m. Tuesday, Sept. 22, 2015: We were wrong. No rain came. And it's hot. Sorry about that.
Rain could provide relief after the weekend's 100-degree temperatures.
It reached 104 in Burbank and 100 in Montebello yesterday. Any kind of wet would probably be welcome.
"An upper-level low passing to the south will introduce the chance of showers and thunderstorms for parts of Los Angeles County Monday into Tuesday," the National Weather Service says.
However, warm rain from the south tonight is an "uncertainty," federal forecasters say.
And if the feds can't tell us with much certainty if rain's coming in hours, imagine how wary we are of predictions that we'll see a historically wet El Niño winter.
In fact, the folks at private forecasting site Weather West, run by Stanford earth science Ph.D. candidate Daniel Swain, say the long-term forecast is for dry weather.
"Seasonal forecast models continue to suggest that November and perhaps early December will be drier and much warmer than average," the site states.
However, for Monday and Tuesday, Weather West predicts "widespread, possibly quite heavy precipitation across a wide swath of Southern California."
AccuWeather.com is also bullish on end-of-summer rain, saying that SoCal could break the record, set in 1939, for the wettest September on record. Los Angeles has seen 2.39 inches of rain so far this month.
"While rain will wrap into Southern California and can lead to some flash-flooding issues, most of the downpours and greatest threat for flooding will spread from Baja California to Arizona and surrounding areas Monday into Tuesday," says AccuWeather senior meteorologist Kristina Pydynowski.

The NWS is more sober, saying that showers could come to the L.A. area tonight but noting that some of its computer models "are not as aggressive" on the chance of rain.
The service states that it has "confidence on cooling for Tuesday," however, which is just awesome.
Unfortunately, NWS forecasters also state that things could remain muggy and that "above-normal temperatures are expected for the remainder of the week."
Fall officially arrives Wednesday. Don't mothball your air conditioner just yet.
