Residents here tell me that wasnt the worst part of this. Now, officers arrived pretty quickly after they got calls about the gathering here. But the crowd police say didnt pay much attention to the officers. They continued to mull around for a while and slowly left this intersection. But they continued on to at least two other locations in the city, including 23rd street in the mission. Police mostly stood by. Witnesses say they didnt try to make any arrests. It seemed unsafe over there. But as far as like the people i was scared it would get violent if the police got really involved or something, but it lasts ten minutes and then they just went on their way. Reporter now statements from the San FranciscoPolice Department confirmed the statement and that officers did not Issue Citations or make arrests but they say they will be taking action. We will be working to identify the people and will use all Legal Resources to prosecute those involved.

Augmented reality. Thats right. Its supposed to be winter. At this point on a record pace. We dont have any rain fall. It will be the first time perhaps since 1864 around San Francisco weve had no rain in february. Right now we are enjoying what is probably the coolest day of the next seven days. In san jose, clear skies. A lot of low clouds, strong sea breeze, little mist on some of the hill tops. There you see 59 degrees. It is hard not to be distracted by the forecast right now. The view looking back to San Francisco clear no degrees. The winds still onshore, but you look at the clear skies out to the golden gate bridge. 57 degrees. West wind at 60 miles an hour. But unlike yesterday, the sea breeze brought in a lot of low clouds. You see there, the skies are clear. As we go through tonight, notice were not looking at inland low cloud cover or even near the coast as we begin to see High Pressure building in. This will lead to a warmup once we get past a chillier start to your morning. Without the cloud cover around, north bay and outto livermore, you one in the upper 30s. San jose close to 70 degrees. Still 60s around San Francisco and oakland. Now toward the inland east bay. So monday through thursday, likely to be the warmest days of the week. Its High Pressure, probably peaking intensity thursday and friday. It could get close to 80 degrees and some of the warmer spots inland. Then our chance for finding showers late saturday night into sunday. Notice that system is dropping from north to south. So the reality check on how much rain to expect next sunday, at least its better than nothing. But again these totals are pretty low. We may contewior, though, as th colder storm systems attract inland tend to give us gusty winds and we can see that next sunday. Lets hope we manage some showers. North winds mean dry conditions. But for the sierra, could be good news. Even if we dont get a lot of showers here, three, maybe six inches of the snow in the sierra. Beyond that, we dont have a lot to look at. As we head into march now, the highs back to the coast. Thats the problem. 5 to 6 weeks really of this pattern.

We said it augmented spring reality because wednesday and thursday a few spots could get close to 80 as we wrap up the final days of february.
