Summer in the Winter
@Jake. I grew up in San Diego and spent many winters working on my tan on the sands of La Jolla Cove. The beaches would be buzzing end of January beginning of February. This was late 70's early 80's so it's not a recent phenomenon.
first timer
Who here is starting a garden due to the panic.. that is me.. I am a first time gardener.. got out of depression by smoking pot.. but now I am an incessant learner and now I want to start gardening- it really helped me out of my depression.. Anyways.. Everybody who knows, knows that there is definitely weather changes coming.. but as long as they keep negating the facts.. the conversion is nipped in the bud.. We can only count on ourselves for survival in ALL CASES... this government is inept.. anyhoo.. I am here for the facts and would appreciate help, especially since I live in LAS VEGAS, NV.. WISH ME LUCK PLEASE.. and send me tips..
Southwest heatwave in January
Every year for the last (omg!)15 years now!, I’ve been observing a week long, (sometimes 2; 2016) heat wave during the last 10-14 days of January. Here in Los Angeles we will see 84*F for a period of at least 4 days. I’m wondering if the F.A. Has kept track of this?, and if so, do they have a prediction for 2020? Today seems to be getting warm. I believe it’s in the high 60’s low 70’s this morning.
Anyway, i seem to be the only person I’m aware of that keeps a record of this micro-summer, which seems to happen RIGHT BEFORE it resumes into flat out WINTER for Feb, March.
I return to your page every
I return to your page every year and come back with the same question, where did winter go in western Texas?
almost 5 consecutive years without snow fall, all due to the weather change
When years ago snow fall up to 4 times a year.
So where did winter go specifically in the area of el paso tx (west texas)?
Nobody questions these weird weather anomalies?
Ok
So how is it that the temps in high desert are 10 degrees warmer during the HOTTEST months..then dump 10 degrees COLDER during the winter? And nobody questions it? I mean come on if we are experiencing global warming I should of been able to drive the high elevations through Thanksgiving right? Grow strawberries into December?
Nope
Immediately after Halloween the temps do a reversal & nosedive, killing our garden WAYYYY before it should of in our area. Buried the only route north besides California in 6 ft of snow, which forces all travel NORTH to take I- 5 adding 6 hrs to the route.
So basically the weather "tweekers" are making it now impossible to grow anything without a greenhouse because it's too hot by May & too cold by October.
The west side of the US is becoming unlivable, both financially & environmentally.
And NOBODY questions it....unreal.
Indian summer
It has been an Indian Summer here in Beatty Nv. ,lows in the 50`s highs in the upper70`s no wind,no rain for almost 2 wk`s
Rain over this winter?
I'd like to know about rainfall predicted for Albuquerque/Rio Rancho area. What month is the best time for roof replacement? The expected rainfall specified by the week expected would be enormously helpful. Thanks.
Winter Predictions for Show Low
I love how I search for winter predictions for Show Low, AZ and it shows me the winter predictions for all of the SW of the United States. For those who are not familiar with Show Low, we are located in a Pine Forest in the White Mountains of Eastern AZ. Our climate is vastly different from the desert areas of the SW that this is focused on. Overall it is just very inaccurate, and if I wanted to see predictions for the SW as a whole, then I would have searched that. Seeing how it is going to be down in the desert areas of Phoenix and Tucson is practically irrelevant to me. I have read other people's comments, and from the looks of it, it seems that this website is just overall not very accurate.
Long-range weather predicting
A lot of people just do not understand what this is. I see so many questions about local weather or a specific date. The Old Farmer's Almanac long-range weather predictions are made way in advance (maybe 18 months). They are based on climate regions and above/below historical averages for temperature and precipitation. And it's true that microclimates are different than weather zones but that's a given. You can't expect these predictions to be any more than general and regional. Historically, I have found that the weather shift happen a few weeks prior to what they say or a few weeks after they say. So you have to look at these at trends. Will it be an extra snowy winter or not?
