Dejavu all over again!

Well, this could be the coldest night since January 5, 2001, when I had my all-time low of 22 degrees (radiational cooling event) and it destroyed my garden.

Weird thing, at 9 P.M. is was more than 3 degrees colder in Homestead than at my place in the Lake Placid cold pocket.

I noticed that it is running 4-5 degrees colder at this time tonight than last night.

I suspect after tonight the USDA will once again have to revise their zone map for Florida. I suspect the frost line will once again plunge farthr south.

It's now 37.9 degrees at 10:17 P.M. This doesn't bode well.

Well as of 9:30 I have fallen below freezing here, 31.6F. I can't bring myself to look at it anymore!

It is going to be a long COLD night. :(

Now I know why there are so many queen palms in central Florida!

I just checked Homestead, Florida, FAWN and it's 33.45 degrees just before 10:30 P.M.! Things don't look good for all of Florida.

Okay I have to get this off my chest, it's no secret how I feel about weathermen.

But last night,or tonight was on NONE of the weather services 5 day advance forecast!

As of very early yesterday morning (1/13) last night was supposed to be the coldest night, then a little better tonight, then tonights forecast just kept getting colder and colder. I am still forecast by some to go below freezing Thursday night now.We were supposed to be out of the woods by tonight,now we are not out even by Thursday night.

This event caught them totally by surprise,and with their pants down,and only reaffirms my observation that weathermen can't forecast themselves out of a paper bag! just sayin!

Larry--

Just looked up the data for Tarpon and the record low maximum temp for 21 January is 48, set in 1940. Congratulations!

Best of luck tonight to you and everyone in FL...your record low for the 21st is 22F (1985) and for the 22nd is a mere 30F. Let's hope you don't go anywhere near that 22! This is a nasty high-pressure center, it was just east of here last night and we had 9 hours below freezing but only hit 27.7F. Lots of places directly under the dome were in the teens. Progs show it centered just north of Cedar Key in the a.m. Watch out!

We hit 32 degrees at 8:30. It is now 31 degrees in open exposed NW side. In a sheltered location it is 35 degrees. The weather forcast on the 11:00 news just said it will be a devastating freeze of 7-9 hours duration west of I95 and the Turnpike . 3-4 hours on the East side. I guess that's all she wrote. :(

What's up with the readings from McDill AFB? It's reading 34F @ 9PM, which is the NWS point forecast low for the base!!!???

I checked that on the NWS. Gotta be wrong.

I am curious. Do most South Florida homes have central heating? I don't know if that's a dumb question or not but, since you obviously don't need it a heck of a lot, I was just wondering. We have it here but it is expensive to run since it runs off of electricity in my part of town. It was on during for a couple of weeks during our cold spell in December.

I can't believe how cold it is down there..... I sure can feel for you guys.... I just got back home and it's currently 22f here on Long Island, but I have (4) plastic tents setup with everything heated - I'd be freaking out if it was uncovered... The only saving grace is that you guys will rebound after sunrise very quickly tomorrow.. It's that awful time between when the sun first rises that I've noticed the coldest temperatures.

This is very, very bad folks! The forecast trend is getting lower even yet. The weather channel just said 23F for Melbourne of a low!

Right now it looks like the National Weather Service has either not revised their forecast for the entire state, or Brevard County is especially going to get hit.

We bottomed out here last night at 29 degrees and a super hard frost. Projected low tonight of only 40 and warming up after that. Florida runs a day behind us, but I just have a hard time believing that it will be that bad outside of North Florida. At least I hope not. Good luck guys.

As of 11:30 PM, we still have another eight more hours to go to get colder!

...Same bat time -- different bat channel...it's 34 degrees here at 12:45 AM (it was 48 at this time last night). This morning the temp bottomed out at 37 (right after sunrise) so there's still a little while to go -- however, for some reason, it doesn't "feel" like it's going to get that much colder (but the forecast earlier was for 29).

I did spend 3 hours covering things and bringing in a ton of potted stuff -- does anyone here know if it is necessary to tape over the drainage holes on planting pots when using them to cover up plants on cold nights? (I guess I "showed my hand" that I didn't do it...). I've got a "plethora" of coverage items (plastic garbage cans, plastic plant pots, cardboard boxes, and sheets) so I'm curious if some types will protect better than others -- this is the first protection I've done this winter so everything has seen 39 numerous times and 37 or 38 a couple times -- I'm sure too many cold dips will impact them so hopefully this is the "last blast" for ol man winter! (although my stuff in the garage will be staying inside for at least one more night after this one -- maybe two)

Good to hear that it's already warming up in Louisiana -- maybe we'll get warmer here quicker than what was predicted...

As of 11PM it was 32.0F at my house in Maitland. I hastily covered a few palms which I had left uncovered yesterday expecting 30F for tonight. I heavily wrapped a 15 foot single trunk Areca triandra in Christmas lights to about half way up the crownshaft since I can't get any higher, I hope it survives! I noticed something odd with my 12 foot Bismarck. About the outer 1/3 of every (huge) leaf has been nipped by last night, the affected area looked dried out and grayish tan. I wonder if I have a more tender than normal Bismarck as I have noticed this some before. My 30 foot Roy. borinquiana looked about 40% burned by last night and my nearly equal size Roy. regia showed no damage, yet.

Since earlier in the night many south Floridia FAWN stations are now reporting about 4 degree higher temperature readings.

Right now I'm reporting 29.8 degrees at 2:57 A.M. At this rate I may well see 25 degrees by sun up. If so, it will be my second most lowest freeze in 11 years here. This should set back my garden for years.

I just checked some FAWN weather towers and noted, to my surprise, that there is little or none air stratification typical of most radiational freezes here. The temperature is virtually the same at 2 meters above ground level as it is at 10 meters above ground level. At the Hastings FAWN the temperature is actually 3 degrees colder at 10 meters than at 2 meters. On past radiational freezes I've seen air temperature differences between 2 and 10 meters range from 7 to 14 degrees. I don't think I will ever understand the physics at play here. Each radiational freeze is always different.

I had 32F as early as 10:00pm Wednesday night, my 6-month old baby boy woke me up at 2:00am for a bottle, and looking out the window it reads 30F outside! Finally got him back to sleep (an hour later), and its still 30F outside. I hope it doesnt get any colder outside, (prediction is 27F) either way im sure there will be ALOT of brown plants in Tampa Bay this week, as nobody saw this one coming!!! :blink:

Still i still cannot believe south Florida has the same temps as me, and some look colder than what i have!! :huh:

YAY! What a wonderful record to set :mrlooney: Im glad something was accomplished yesterday!

Sitting at 35.2F here at 420AM according to my Davis Vantage Pro weather station, so not too bad even though there still remain ~3-4 hours of cooling left.

I see that the warmest areas of Pinellas (downtown St Pete and St Pete Beach) are 42-44F at this hour, so theyve really lucked out.

In south FL, many homes just have heat pumps. In central FL, many homes also just have heat pumps, but with backup electric heat strips.

I happen to have natural gas in my area, so we have gas heat, and believe me....my wife has it BLASTING right now!

I've been below 32 since 3:30 am, it's 5:30 now & it's 32.4 :rage:

I can see the cars covered in frost. I haven't looked out back yet but I suspect my landscaping may change after this one. Every source I checked online dropped the ball on this one. Can I sue? :angry::hmm::lol:

Still above freezing in most of Dade and Broward at 5:30 AM, per AM news recording stations. Coldest temp so far was Kendall at 34, Homestead 36. Warning, objects outside may be colder than indicated!!

I actually expected worse, but still a couple hours to go.

Best of luck to all!

Wx-radio announced a hard freeze for all of W. Central FL except Pinellas and Lee counties! ACK!

At 5:00, our therm (not a hi-tech one) showed 37. No ice in the water in the birdbath. Car windshield had a bit of ice, but nothing else did. NWS had forecast our low to be 37, so it might have been. The two closest reporting stations to us on wx-underground showed 34 in Pinellas Park (always colder than us) and nearby Disston Heights reported 39. They are at 62' elevation; we are at 44'. Pinellas Park is lower.

We plugged in the Christmas lights as the temp could still drop.

About the central heat - we don't have it. We have a wall unit with heat which we use a few nights a year, and that's all we need. Mostly we use the wall unit for A/C.

Looks like the urban heat island helps again in Orlando, OIA dropped to 31 and went back up a bit, and the exec. airport hasn't even hit freezing. A far cry from mid 20s. The airports readings are usually not that representative of the area as a whole, especially during radiational cooling nights. Also looks like the temps at alot of the personal weather stations in the area are on the rise.

Yeah, I noticed that Orlando Exec (Sanford, right?) is two degrees warmer than Coral Springs in Western Broward, now sitting at 31F. Looks like Orlando may be better off than farther south.

Been up since five and the temp has been holding steady at 36.4. Looks like maybe the heat island effect from Lake O. has been helping me here. Just praying for the sun to come up QUICK!

Yeah...that funky big temp drop right after sunrise we were discussing earlier!

Here are some images to the wunderground sites around the area...its easier to show pics that to list the various temps-----
