Winter weather
When will we be getting a substantial amount of rain and snow in lake Arrowhead ca.
With the weather manipulation
With the weather manipulation and SRM programs in operation,the rain continually gets steered north of commiefornia,even with a strong el nino in play.
Last winter we had one of the strongest el nino's,yet most of commiefornia saw waaay below average rainfall.With your forecast you call for below average rainfall in the south-whats new..
Weather prediction
Hi. When will there be snow in Big Bear from Nov '18 to Mar '19 (winter)?
Weather forecast
Maybe your lick&spit weather forecast doesnt consider the US military heating up the ionosphere with HAARP..
it not only produces a better telecom transmission, but is causing all the fires, AND is literally frying the last of american nincompoop brains they had left.
Make sure to always vote for the Master... the Skull&Bones.
This summer
What are we looking at for late July to early August? Do you anticipate very hot temps in San Jose (90s or higher) or will it be more reasonable - or can we just not predict that very accurately yet?
Cooler than normal?
My son has been in Montana for six years but moved back to NorCal in January. Yesterday he remarked that it seemed a lot colder here than he recalled from growing up here.
Do the stats support this? Is the average temperature here dropping, or is this winter just one of our anomaly years?
Spot on prediction about March, though. It's raining buckets here.
colder than years back
The first question that comes to mind is, how old is your son? because, to a certain extent his interpretation of average temps has to do with when he experienced them—when he grew up. Many people remember weather as being different now from their childhood—and many are correct. But the buzz we hear is that it tends to be warmer …
Averages, or normals, as we explain in the 2018 print Almanac on page 217, are based on 30-year periods. Currently that is 1981 to 2010. The period advances every 10 years. Virtually all meteorological services/orgs in the world subscribe to this calculation. Here is a page where you can look up a few California cities: https://www.currentresults.com/Weather/California/average-annual-city-te...
Here’s one from NOAA with records through the end of last year: https://www.ncdc.noaa.gov/sotc/national/201712
Here’s another page, perhaps more current (you do not say where in NorCal, so not sure if this covers you): https://gacc.nifc.gov/oscc/predictive/outlooks/myfiles/assessment.pdf
Records suggest that the planet has had some of its warmest years in the past 20 years (or less); we seem to see a headline to this effect almost every year! Of course, not every place is warmer, but in terms of averages, California has been in that number.
Make it warmer and a little bit wetter
Tired of flipping off the local TV weather folks when they predict (more and more accurately) cold weather. Even the Weather Channel is getting it right. It used to be that the temp was typically 2-3 degrees warmer than predicted. Now, it's always as cold as predicted, with not enough rain not early enough in our "winter" - which is beginning to earn that label since you guys started this "global warming" thing. We don't miss the seasons enough here to be ok with having to wear long pants and sweaters for months at a time.
So how about it? Y'all have been around since the Post Office. Everyone else is happy with their weather. No one believes in science anymore anyway, so who's going to notice if you do just one little favor for just one little regionette? Something like 8-10 degrees warmer, with about an inch and a half of rain once a month (You can split it up into two days if that's easier) - this is not much to ask, and it would really cheer us up and make our yards and mountains green here at 34/-118. Not to sound crass or anything - because we know a heartfelt thanks is the best reward, but we'll gladly underwrite a substantial subscription contribution if you would kindly honor our request.
the weather you want
If we could give you the weather you want in your regionette, we would happily do it at no charge. In the meantime, we’ll aim for 80% accuracy and see how it goes. (Love your signature name, btw. And if you are, perhaps you have more control over our meteorology than we do!)
every day changing weather systems
I am extremely interested in how Escondido,ca can have ever changing temperatures especially in the up coming summer i would be interested to see how cold it is in summer nights in the island part of San Diego.
