Possible Florida Freeze - January

Why is Florida always so magically warm? The SE ridge always protects it; why isn't there an equivalent ridge in Southern Mexico, which can come up to protect Texas?

I don't believe Fl is so magically warm. Hell, most of Fl has ultimate lows well below our lows here in CA at 800 miles north. South Fl however, yeah, they have latitude/surrounded by water to moderate things big time.

   Here is some stats for   Daytona Beach in   January.

When the door opens from all the way to North Canada , we get slammed . This weekend is just a run of the mill cold front overall for

this area.  South Florida does better , but when it's on , it's on.....

I had a low of 38 this morning in Cape Coral, about 4 degrees colder than forecasted. Should be warmer tonight, hopefully.

It only made it to 51F today, but a slight breeze has picked up now so perhaps, that will hold temps up. Otherwise, if it calms, then we are in for a real cold night. Then the warmup begins. They missed this by 4-6 degrees easy. However, about a week ago I did mention about the "dip" coming. It appears the pattern is 7-10 days of warmups then a coldpunch, then warmer.....<_<

We made it to 64F today, that is what makes the difference being here in South Florida instead of Central FL.

More concerned with tonight than last night. No clouds! Non warm up during the day. Can tolerate between 30 and 32 no damage here, but depends on duration.

Low this morning on the Isabelle Canal: 40.5F

Today was sunny and in the low 60s but the winds are howling.

Forecast low tonight: 44F

On the plus side, if anything, we got 0.7" of badly needed rain

Did it freeze at your place last night? I had 31.6 (open yard) and MacDill AFB also had 32, but most locations I checked on Wunderground were more like 33-34f.

No, appears to not have froze. Sentinel plants look okay. 

Chaya, Spanish needle, papaya, if they look cooked spinach, trouble. No cooked spinach look, no problem!

 

I gave up measuring long ago. Without a proper Stevenson screen,  you get scary low temps that aren't real.

 

Been meaning to set something up for a while now!

I go by how things look and feel. Also, use wundermaps, but I am suspect of some of those readings also.

By how many degrees do the readings vary from real temps without using a Stevenson screen?

By your comment, it seems without a Stevenson screem temps read much lower than what they really are.

5 year high 42.2C/108F (07/06/2018)--5 year low 2.3C/36F (12/27/2015)--Lowest recent/current winter: 3C/37F (2/24/2022)

You make some very good points. I've thought a lot about this before and concluded thermometers are only useful in comparing one day relative to another. You just don't get precise numbers and you can't really compare with other people on Wunderground since placement makes a huge difference... Still though, it is fun to keep track of it even if it isn't meaningful. LOL

Kind of blindsided by this cold snap while I was on a trip over the weekend.

Wasn't putting much mental effort at the possibility of a damaging freeze at my house. The forecast low when I left Friday was 26 which is significant but not damaging for important things like my citrus. Moved all tender stuff in greenhouse or indoors before leaving.

It was 11 degrees at St. Louis upon arrival- ouch. I really enjoyed it though and especially the very light cover of snow on the ground. 

Got back, and was somewhat horrified to see my weather station show 22 degrees as the low this morning. Went in the backyard with a flashlight. All annuals are annihilated. Bananas are toast. All leaves on the Strelitzia nicolai (White bird of paradise) will probably need to be cut off completely (shouldn't lose the plant to the ground though). Citrus leaves slightly curled.

Yep, well, it happened- no mild winter a second time in a row. Actually pretty thankful so far. I consider 22 a sort of cut off point below which is very damaging.

Wow, 22f is pretty cold! Sorry to hear that happened. When is the last time it was that cold there?

True about record lows in CA vs FL; indeed, Florida can get hit pretty hard. However, I was referring to it in relation to the rest of the South; there are plenty of times the peninsula (and far north on it too) is basking in 80-90F heat, while the rest of the South is in the deep freezer; basically, no penetration whatsoever. The way the differentials are suggest something greater than just simple water-moderation, probably a Caribbean Ridge of sorts.

Meanwhile, on the other side of the Gulf, the cold fronts just drive right down to even Tampico, with no stop; I just don't know what atmospheric dynamics prevent a Caribbean Ridge type-feature from jutting into Southern Mexico, allowing that place, and Texas, to be walled of from cold, at least for a turn.

Temps held steady through the night, reaching 40F at midnight but now 38F at 6am. Now the warmup begins. Looks like 75-80F statring Tuesday but with the GOM recently chilled, I'm curious to see how that cooling seabreeze affects my yard...a mile away I am. Amazing! GOM went from 71F to 58F just over the weekend. :o

2 winters ago was 18 degrees for us. However, for the winters I've been here since 2007: minus 2010, 2014, and 2015 it didn't get below 9a. Below that 9a cut off, things like CIDPs, Washingtonia start getting seriously burned.

I see the temp got around 37 in Kissimmee yesterday morning. If I figure right, the last time it got that cold was 2 winters ago in February.

I wonder how much longer before the Orlando area has an actual freeze? I was just marveling at weather history for Kissimmee. I can't imagine the carnage temps like this would bring with all the tropicals there now.

Sorry, can't figure out the qoute thing, but without a thermometer or thermistor properly set up, in an exposed location it can vary widely from the true value, as much as 5F. Maybe more.

That's why I us the FAWN site, or average of several nearby wundermap stations.  

I once measured 22F in an open part of the yard with just a remote sensor in the open,  one in protected spot was reading 30F. I had no damage that year,  22F would have shredded most of my stuff!

Low this morning: 44.8F

I hope the warmup begins tomorrow. All this cold is making my bronchitis worse.

Went down to 34.5.  Had a few little drops of ice on the top of the windshield.  The warmup is much appreciated.

Wow those are low, and all within a short period of time to boot. It'd be rare to get that cold once every 5 years now. I live near Kissimmee so your right. When I got started with palm trees I assumed the Foxtails, Arecas, Bottles, etc. we're all native to this part of Florida because there's so many of them. Half of the stuff they sell at the hardware stores would die with temperatures like that. That being said I wonder if the city's heat island effect has an effect on keeping the temps warmer than the 70s/80s? Much of Osceola County back then was rural farmland, now South Orlando's suburbs have begun to grow into it.

It has been a few days since that minor freeze and all my palms look perfect still. This was expected, though I was slightly concerned about a young royal. 

I drove past some nearby coconuts today and they looked about 25% bronzed. 

If this is the worst the 16-17 winter has in store for us I'll be thankful.

What area are you located in Tampa? Our lowest temp here on the lakefront was 36f so thankfully no freeze.

Your reading of 36f is a little surprising, is that out in the open or next to the house?

I'm by Gunn and Dale Mabry. My thermometer out in the open recorded 31.6f, but the one in the lanai had 34. By comparison, MacDill had 32f, TIA 34f, and Knight Airport on Davis Island had 35f.

its near house but not under a lanai or overhang.  we are in a very good microclimate (elevation plus deep lake and canopy). I did note a weather station on a neighboring lake was 34f for low which may be more in open. The plants tell story better, heliconias and bananas still green, lychee blooming. I did have an areca macrocalyx in a protected spot and it was not too happy, but I think they don't like anything below 40. quick trip back to 80s. Even if you recorded 31.6 in open I am sure duration was very short,

That does sound like a nice microclimate of yours. I hope to see some garden pics one day. :)

I drive past another nearby coconut yesterday and it was 60% burnt. Nothing else, bananas and adonidias included, have shown any damage.

Its remarkable coconuts can take so much damage from such a mild freeze.

Have a decent cold front making its way south over the peninsula. Nightly lows in the 40s through Tuesday morning. Monday night is forecast to be clear, dry and no wind so Tuesday morning may flirt with mid-high 30s.

51 at 6:45 this morning. Don't think we got above 52 for a high yesterday. Not sure we ever actually dropped below 50 at any point. I hate this cola :-(
