It was freezing cold last night. Does anyone know how low the temperature went?

Still waiting for the ice to thaw up here.

Frost all over the cars and I am down by Hammonds. Cold!!
COMMENT 362504P	2013-01-11 11:39 AM
I have a question about this. Many times over the last month there was frost on the rooftops in the neighborhood. According to WeatherUnderground the temps never got below freezing. Is it possible to have frost without freezing temps?
ROGER DODGER	2013-01-11 11:48 AM
Per the top of my head about 29..
COMMENT 362540	2013-01-11 12:55 PM
2504.... frost is frozen water/moisture right? Albeit very thin layers of it. Can water freeze when it's not freezing out? Water can vapourise without boiling.... so can it freeze without freezing? Ha, and you thought gun violence or the fiscal cliff were big issues!!
COMMENT 362557	2013-01-11 01:43 PM
"Frost is formed when the temperature of solid surfaces are below the freezing point of water and also below the frost point.The frost point is the temperature to which a given parcel of humid air must be cooled, at constant barometric pressure, for water vapor to be deposited on a surface as ice without going through the liquid phase. If a solid surface is chilled below the dew point of the surrounding air and the surface itself is colder than freezing, frost will form on the surface. Hoar frost can form even when the air temperature a few feet above ground is well above freezing. Nonetheless the frost itself will be at or below the freezing temperature of water".- Wiki

31 degrees near Costco at 6:00am

The doors on my car were frozen shut.

Have been scraping frost off my windshield, Magnolia Shopping Center area, on and off for a couple of weeks.

29.6 degrees/ 29% humidity @ 6:30 am in the harbor.
COMMENT 362641	2013-01-11 04:44 PM
@362504P The rooftops are colder than the air, thus frost can form.
COMMENT 362650	2013-01-11 05:46 PM
21 degrees in Buellton this morning.
COMMENT 362681	2013-01-11 07:16 PM
641-How does a roof get colder than the surrounding air? Refrigeration coils?
COMMENT 362705	2013-01-11 08:28 PM
Out near Nojoqui Falls, 23 degrees at 7 am Friday morning.
COMMENT 362738P	2013-01-12 07:44 AM
681: in a way, yes, refrigeration takes place. Water vapor condenses on glass or metal or even a rooftop. Wind moves air over the condensation evaporating it causing heat to be removed from the surface. The next water vapor that condenses there freezes and the process repeats....
COMMENT 362753P	2013-01-12 08:47 AM
As a follow-up to my explanation as to how refrigeration occurs Naturally (no coils, no freon...) to any surface exposed to air, Just think about why it is that you get colder when you get out of the pool even on a hot day then if you were to stay in the water, Or if you were riding a bicycle and want cold water to drink just put a sock around your water bottle and ride about half a mile with the wind blowing over the sock that is damp And Presto voilà Coldwater! You say it's 100° and you're dying of heat? ... Wrap yourself in a wet towel and turn on the fan... Isn't science fun? And quite practical too! :)
COMMENT 362754	2013-01-12 08:55 AM
563 - car doors frozen shut? No, I don't think so. It was cold but not that cold. 30 degrees but warms up another 20 to 30 degrees during the day. If it stays cold, we'd have a problem. If you live outside, you have a problem without getting inside. It's winter, we don't even snow unless a freakishly cold front hits with a storm and that usually comes in March, the snow melts in the next two days. Enjoy the bliss of living on the American Riviera.

Colder than a witch's tit! (as we say in jolly old England!)

578 Great link--thanks! You can go on the map and see exactly where that weather station is located. I looked at one of the other sources of data listed at the bottom of that page--Yankee Farm--is there a way I can find out exactly where that weather station is located? Is there a way to find how this entire site is put together and how to add a weather station? Thanks.
COMMENT 362786	2013-01-12 10:24 AM
It was snowing the other day on the 154 about 2:00 in the afternoon on Thursday but it was not accumulating and was mixed with hail and rain. For those of you who are familiar with winter weather you know that when falling rain is about to turn into snow it will hit your windshield and form a starburst effect rather than running down like rain. That indicates the rain is very close to becoming snow and a decline of a degree or two in temperature will result in the rain (or slush) changing into snow.
COMMENT 362791	2013-01-12 10:43 AM
Actually, yes, had car door frozen shut a couple of weeks ago on SB westside. Actually, it was the weather strip that froze to the car, we had a heavy frost that morning. I heard to prevent this, put silicone spray on the weather strip.

Timothy, read the headers of the columns and click on the "Santa Barbara", the second column from the left. It leads you to a map of the weather site including lat & longitude. This is the result for Yankee Farm: http://www.mapquest.com/?q=34.41,-119.75 You can also google the weather station ID number. good question, how to be included. Easy: Google "local weather exchange network"; lots of info. It's part of Wunderground.
