Well, it’s time for a new thread. Calendar spring is here now and it also appears that the real spring is too. Yesterday on Sep 1 we had a 24C day then some small rumblings and a thunderstorm which dropped about 5mm of rain. We are now at the point in time where the weather is gradually on the improve and the weeds are growing like mental. Hopefully a great growing season awaits and the palms flourish.

General 2023 USDA Plant Hardiness Zone Map Discussion 1 2

Jumping off the FL-specific thread, I figured I'd start a general discussion on the release of the latest map by the USDA: https://planthardiness.ars.usda.gov/ Kicking things off, a few interesting things I've found: Inclusion of a significant amount of 10a throughout SE Louisiana including a small section in DT New Orleans along with a *very* small amount of 10b Northernmost extent of 10a extends into SW Oregon (Brookings) Poor representation of cold sinks in microclimates throughout the Rockies: Jefferson, CO hit -24f a couple of weeks ago during a fairly typical October cold snap, but they're listed at 5a (-20f to -15f) and will routinely fall …

Its not winter yet, thankfully, but the cold fronts have started. There have been cold fronts periodically, but you could never tell a difference from them, that is until the week before last week. A cold front came through and knocked morning temps into the low 60's, highs remained the upper 80's though. Looking ahead into this week, another cold front is forecast to sink south across the eastern US. Morning temps here are currently forecast to be in the upper 50's toward the end of this week, highs in the upper 70's to low 80's. If this comes to pass, it would be the first noticeable cold front of the season

Hurricane Ernesto visits Puerto Rico

So much rain in 12 hours that my 11 inch volume rain gauge overflowed long before Ernesto retreated. Muddy river from the street above poured down part of my long driveway but no dramatic landslides near me thankfully. Awaiting assistance to try to right some now nearly horizontal palms and a bunch of other ornamental/fruit trees. I won’t miss two tropical almonds that broke and fell on each other. Lots of chainsaw work awaits, but my trusty sawzall and I cleared a passageway to reach my gate. Note the big Roystonea borinquena unscathed. I got city water back this morning. Still waiting for electric…

Certainly feels like it. Been seeing many new comer plants and palms. Always been a zone pusher but less and less concern. Anyone else think the same? Maybe just a decade from the killer cold snap.

This new Future Urban Climates app from the the University of Maryland Center for Environmental Science was just featured in the Los Angeles Times. It shows a prediction of what your city's climate may look like in the year 2080. For example, in 2080, the climate in Charles Village, Baltimore will be like....Oil City, Louisiana haha. New York City in 2080 will be analogous to Ola, Arkansas today, apparently. App is here: https://fitzlab.shinyapps.io/cityapp/ Explainer here: https://www.umces.edu/futureurbanclimates

MAJOR SHOCK / The difference a few years can make / NOWData Update to US Atlantic Coast PHZM

Don’t shoot the messenger, some major surprises in the data but at the same time a continuation of the trend seen in the 2023 Map put out by the USDA for 1991-2020. This map is “quick and dirty” using Google earth and may trigger some climate change skeptics. It covers 1995-2024 using NowData. Shockingly, the Virginia Beach-Norfolk is thoroughly 8B, 8A has engulfed the entire Chesapeake, Lewes, DE popped up to a low 8B, 8A has crept up the NJ shore, parts of Long Island (La Guardia in Queens, NYC to Syosset) are now 8A, Montauk, NY on the tip of Long Island is now 8A, several stations in coastal Connecticut are now 7B (crape myrtles going “viral” now in pa…

Thought I’d share with the Texans here that NWS was predicting 2-4” of rain for us throughout the week. Three more full days of rain expected and we got 2.55” yesterday and i’m up to 2.9” today. Woohoo!

Anybody else think it's bananas that the record low in Brownsville (12) was in a February and the record high in Brownsville (106) was in March? Is there anywhere else that's like this?

Monsoon 2K24 ..Poker Hands, Content, and Hard Edges...

After a sometimes wet / sometimes cool winter, we arrive at what can be the best time of the year here in the Southwestern U.S. and Mexico as another Monsoon season begins.. The heat, Cicadas and Toads, Saguaro fruit and Mesquite Bean harvests, hot, lightning - filled nights / humid afternoons, and lush tropical greenery which can spread far and wide once the rains arrive ..this is the season anyone who appreciates and respects the unsurpassed beauty of such things eagerly awaits every year.. While no two years will be exactly the same, we all understand not all will be perfect. Some will bestow upon the viewer the greatest gifts the gateway to the tropics has to…

Florida rains
by RAP- 10 replies

We received about 9” of rain and I see there is an area in my yard by my Triangle palm that collects water in these downpours. The air roots are above the soil level and not under water but the soil is very wet. Any recommendations to prevent water from collecting? I am thinking about a French drain near it but welcome ideas. Thank you

Im just curious at what temp does frost start to occur on the grass? What about trees? If its on the grass is it on the trees? I would think not because the cold air sinks. Why is it I see no frost on trees and palms yet on the grass. Im full of questions, also when you see frost on the ground, like a hard frost, what temp does that occur? I have never seen frost on the trees here. Yet I see it on the grass and sometimes everywhere on the ground. And why on the roof too? Lol, sorry bout all the questions. If you can answer them, I would be happy because on most clear nigths in the winter, there is usually frost on the grass and roof.

South Texas vs. South Florida

Which is more humid generally? I don't understand dew point vs. relative humidity. Obviously they're both hot as f***. I noticed that our temps lately have looked something like this... Brownsville Wunderground stations (temp / dew point): Whereas in Florida (Miami-ish) you see: I don't really understand dew point vs. humidity. Maybe someone smarter can explain to me.

Texas Freeze Map

Hey everyone - As I drive around and explore my new state, particularly north of here, I find myself trying to piece together what the 2021 freeze might have been like based on surviving palm populations. At one time, I remember there being a map of Texas with all of the temps for towns depicted on it, so you could have a clear picture of where the lows were. I can’t seem to find that now though. Anybody remember what I’m talking about?

So, I live in Missouri and I’m ready to get out. I can’t stand the cold, and I HATE the snow. I’ve wanted to move away for a long time, and I’m pretty dead set on doing it soon. I originally wanted to move to northern Florida, but I started to lean more towards SE Texas because of the cost of living. I’m a paramedic, and most jobs in Houston start around $60k. The majority of jobs in Florida start around $45k, and the price for homes/rent is generally higher than Texas. This could change, or I could go into nursing and make more money.. but the principle is the same. Florida = Less money and higher rent, Texas =more money and lower rent. With this current freeze, I’m…

I figured with a cool down already happening and forecast to continue into the rest of October this is more relevant than October would suggest. My forecast high next Tuesday is 72 and that's not far off from "winter". El nino is making an appearance too, so the peninsula already has a severe weather threat with the current system. Models are forecasting the whole eastern US as cooler than average again for the month. My hope is that the pattern does not set up to be cold and cloudy all winter but I'll take clouds if it means no freezes this season. What does everyone do to prepare for an El nino winter, if anything?

Hello PalmTalk members, As all of us in the Central/Eastern US are aware, our dreams of trouble-free palm growing and increasing of climate zones designations, have been more an more confounded by freak and very severe cold weather plummeting all the way to the Gulf Coast, often annihilating cold sensitive palms in these regions. I happened to have the below video (posted by PBS Terra) recommended to me in my YouTube feed and thought that this was valuable to share as it makes a lot of sense in what the reality has been in spite of recent zone jumps being published by the USDA. Hope you find this as interesting as I did.

USDA climate zone map updated

Do people know about this? Apparently the map was updated in November to reflect the last 30 years of climate data, and quite a few areas have been upgraded. Link for those who can access Washington Post articles: https://www.washingtonpost.com/opinions/interactive/2024/climate-change-backyards-plants-birds-migration/?itid=hp_opinions_p002_f001 And a link to the new map: https://planthardiness.ars.usda.gov/?itid=lk_inline_enhanced-template You can search for your zip code and see whether it has changed. Sadly (or not), our zone remains 10a, cooler than most of San Francisco which is 10b.

An analysis of the historical occurrence of freezing temperatures in Brownsville, Texas
by Sabal_Louisiana- 9 replies
- 2.9k views
I am intrigued that such a southerly location might experience temperatures below freezing so I set set out to see just how often they occur there and if any trends are taking place.. The station used for official climatological data is at Brownsville/South Padre Island Intl. Airport located at 25.9146, -97.4231, 20 ft. above m.s.l., a few miles east of city center. It is representative of the typical meteorological conditions of the local area. Primarily, let's focus on the period 2000-2024, with data for the period easily available in tabular form from the NWS Brownsville webpage. The average annual minimum temperature for this nearly 25 year perio…
