What is your current yard temperature?

I have my new thermometers set up and it’s interesting to see how big of difference makes. The fully exposed thermometer is 58f, the lanai thermometer (my official one) is 60f, and the south side of the house is 66f.

Glad to hear you got a setup going.  I modified mine this year by decommissioning the old sensors, at least temporarily so they won't interfere with the new rig.  My setup is now one main weather station in the only open part of the yard left and a few liquid thermometers.  One of the liquid thermometers is in the Maypan bed as a double-check against signal interference from other weather stations that might be broadcasting nearby.  Thus far, the new weather station is congruent with the liquid thermometer.

Out in the open, my record on my new setup is reading 61.2F  My liquid thermometer nearby is roughly the same, telling me the unit is calibrated well.  Those lucky ducks over in Orlando are still in the mid-60s.

It's supposed to cool down tonight.  It's still 73F with a dewpoint of 71F here in Melbourne. 

It will take a while for the chilly air to get over there.  That's one big advantage to being on the east side of the state.  Most of the time you won't go as low and, even if you reach the same low temperature, it often takes a lot longer to get there.

Why is that?  We are talking about less than 100 miles.  I looked at the weather underground stations across the state and southwest Florida is cooler with a lower dewpoint than east central Florida.

Nice set up, I might have to get a liquid one too. 

At the moment I have 3 Ecowitt sensors that are basically the same as Ambient. I just didn’t want the anemometer and this worked out to be cheaper.

I’m curious as well. There’s definitely something about being further east that’s beneficial. I think it’s because the further east you go the further the cold front has to go to get there so there’s a delay.

@UK_Palms How fast do your beccariophoenix alfredii grow? I have just checked on them and since early September they have all pushed out 2 new fronds. Including one in the last month so they seem to grow pretty well in fairly cool conditions. Even though the average temperature in October was only 15.1c here. Lets see how they handle the cool winter temperatures in a pot.

The gulf stream is also on the east coast and the sea temperature is normally warmer on the east coast. The wind is also coming off the ocean most of the time from the east or south on the south east coast of FL. Also what you said.

I don’t think it’s the Gulf Stream, more just the eastern positioning. 

I actually have been wondering more about the helpfulness of the ocean on advective nights since there’s always a land breeze. My theory is the intercoastal waterway plays a bigger role than commonly appreciated and the ocean’s influence is limited.

Often overlooked because of the short straight line distance is that they're on the other side of the Lake Wales Ridge.  Even though the elevations in peninsular Florida max out at 312 feet at Sugarloaf Mountain, it's probably enough of a speed bump to slow down weak cold air intrusion like we are experiencing tonight.  The top of the hill on Clubhouse hill in Lakeland in 272 feet and Bok Tower/Iron Mountain is listed at 295 feet.  There are several other points along the ridge that are elevated around the Clermont area that may slow weak cold air flow entering Orlando and points south and east:

I think another factor is the amount of straight lines with no substantial water modification that are available on this side of the state.  The bulk of our cold comes from the direct north or northwest.There is a lot less water between the north and Tampa/PlantCity/Lakeland vs. Orlando/Kissimmee.  With the more common northwest flow, the St. Johns river and the lakes it forms along the way probably modify the air a good bit.  Lakeland can get hit hard either way, which explains our lower average temperatures, while our record low is actually not bad in comparison at 20F, likely due to our elevation.

Isn't the average temperature on the south east coast also warmer during the winter except for instances when one place has a large urban heat island such as Tampa?

[Jimbean]

Current temps.  Nice weather everywhere except going down the east coast and the southern coasts, still warm and muggy.

Yes, and I’m convinced it’s because the Gulf is too shallow so it gets much colder than the Atlantic during the winter. By extension, I think the Gulf’s bays/intercoastal waterways get colder than the Atlantic ones too.

Interesting theory about the Lake Wales Ridge, but it seems like that would only work if there were basically no wind to overcome the hills. I think it’s just that the cold air has to travel further from the NW to get to the east coast at the same latitude.

Brrrrr only 12.3C / 54F here at 2pm. Winter is knocking at the door.

Look at the sea temperatures around Europe though. I’m guessing this is a result of the ongoing La Niña, but likely also the Arctic warming in conjunction with Gulf Stream influence. Winter is going to have a hard time getting established for much of the continent, especially Western Europe.

Apparently backyard microclimates are harder to predict than I thought…

Yesterday I mentioned I had a fully exposed sensor and it was about 2f colder than the one in my lanai. I reinstalled the exposed one today so it won’t get any sun, but, to my surprise, it’s about 4f warmer than where I had it yesterday just 20’ away. Both are along the back fence with open sky above so I figured they’d both be pretty cold, but apparently not!

[UK_Palms]

9.1C / 48F at 2am here. Winter is going to have a battle to get established this year. After a brief sort of 'cool' spell, if you can even call it that (a single low down to 5C / 43F on Sunday night), temperatures are then forecasted to get progressively warmer again as we go into December. Central Florida will be having their first frosts before me at this rate.

 

Strong Atlantic (mild) influence in the long-range forecast. Nights exceptionally mild for 51N going into December.

 

The warming trend is clear amongst the GFS ensemble pack. These are forecasted 850hPa temps measuring the air mass in the atmosphere at 850 meters. Looks like we are importing the airmass from Spain and the Canary Islands, which has been a common theme this autumn, and this year in general.

[Tyrone]

Max so far today just before 1pm, 12.9C, but at the moment it’s around 11.8C. Frigid. 

[Tyrone]

3.30pm 9.7C and pelting with rain.

[Foxpalms]

The Low last night was 47f/8.3c in London its currently 7.48am and clear skies, the temperature is slowly rising and the max UV is only a 0.7. @TyroneYou're weather today sounds like the forecast we are going to have next week cloudy, rainy but mild. The max sun altitude is 19° today.

7:30 am EST - 55F, Cold front pushed down from the north. First chilly day this Fall. 

[RedRabbit]

It was warmer than expected this morning with the coldest of the 3 thermometers recording 49.6f.

[Silas_Sancona]

Nice cool start, on the way to a nice Friday finish..  Weekend looks good too..

For now, Thanksgiving week ahead looks pretty decent..  Local forecasters have been talking about the possibility of an " under  the radar"- type of storm skirting by the N.E. corner of the state by Wednesday, before dropping south / southeast somewhere near El Paso that might bring some snowy travel to New Mexico on Txgvng. day ..not showing up in any recent model runs ..so,  might be a dud ...or something to keep an eye on.. We get nothing but maybe some wind / few clouds here regardless.

Better signs for another compact storm bringing more rain to N. and parts of Cen. CA / snow in the Sierras ..maybe some rain / snow into N.W. Nevada sometime after next weekend. We'll see how it evolves.


 

Beyond next week, we'll see if the CPC's suggested pattern change in the 10-15 day outlooks sets up.. Very obvious drier/ warmer signal for most of the West in the last several GFS / GEFS model runs. Today's PNA outlook is still on board, at least for the moment.. Perhaps revisiting negative territory briefly near ...or just after the start of December.

Yesterday maxed out at 59f/15c in London, it's always warmer than the forecast when it's sunny.  It's currently 48f/8.8c under clear skies with periodic cloud at 4.07am. The wind speed is 0mph.

This winter so far is above average so cant complain. No sign of any long periods of below average weather or cold, just cool weather. Hopefully January and February stay mild since those are the 2 months that there's a chance of light frosts. Not bad for 51N though when you consider places like Amsterdam just 190 miles east have a low of -5c/23f forecasted for this evening with a high of 3c/37.4f today compared to London's low of 8c/46.4f forecasted for tonight.

[RyManUtah]

29F / -2c. Been running a chilly 10-15 degrees (Fahrenheit) below average for a couple weeks now. 

[JohnAndSancho]

It's currently Very Uh Oh here according to my WeatherDoge app. 

[UK_Palms]

Max of 11.3C / 52F on Saturday during this 'cold' spell. No sign of any frost for me still in the forecast with nothing below 6C / 43F for London during next few nights. The days and nights have actually trended a little bit milder over the past 24-36 hours. We might be pushing 15-16C / 60F come Thursday.

 

A load more rain is expected to fall on Monday, but this is already one of the wettest November's on record for me here. I have had about 300% of my usual November total up to 18th. Many places are going to register their wettest November on record. The October - February period is getting progressively wetter and milder here.

Max out at 53f/11.6c on Saturday and it's  currently 47f/8.3c. The Netherlands look very cold tonight, you can definitely the difference between being near the water and in a city there.

[kinzyjr]

Feels like I switched coasts today.  A high of 59F and a low of 53F with light rain all day.

Its been a dreary day thats for sure. Temps were pretty cozy over here though L 61- H 70 drizzle all day.

[Xerarch]

Currently 47 degrees at 7 pm, I’m ready for this prolonged cool spell to end, supposed to be upper 70’s for Thanksgiving in a few days though so that will be welcome. 

[kinzyjr]

A welcome change in the air.  Almost 70F at 9:15PM.  Much more Florida-like.

[bubba]

76°F at 6:52 AM EST.

[UK_Palms]

Brrrr, pretty chilly today and only 9C / 48F at 3pm here. The coldest day so far this autumn/winter and the coldest day during this brief ‘cold’ spell that we are experiencing. However temperatures are due to rebound again with it getting a lot milder from tomorrow onwards.

I can’t believe how many trees and bushes are budding up here. This shouldn’t really be happening until late February / early March at the earliest. These trees think it is spring nearly and are getting ready to shoot new leaves! It’s kind of weird seeing the older, brown leaves still dying back while new shoots are also emerging on the same branch! Some deciduous trees still have green leaves on them as new leaf buds are forming. It has been a very weird year! I still haven’t had a frost here yet, despite being 35 miles inland from the coast with no UHI.

[Xenon]

60F just past noon. It's been an absolutely miserable 10 days with highs in the 50s and lows in the 40s. But it looks our big warmup is on the way nearing December! Looking forward to more 70s and 80s 🥶

[GottmitAlex]

[Foxpalms]

52f/11.1c in London and sunny. Hopefully we should be getting the winds from southern Europe this week from tomorrow.

[Ryland]

Starting off the day with 6.4ºC (42ºF) from an overnight low of 6.0.  It's been solid winter weather here now for over a week with a run of 8 days below 10ºC (one day reached exactly 10) and my coldest of the season so far earlier this week - 6.1 high and 3.4 low.  The diurnal variation is tiny right now, most days being less than 4º difference - with one special day of 17 November, high of 8.7 and low of 8.1 making just 0.6º difference!  No wonder it feels cold all the time.

Looks like we have another run of 10º+ days coming up which will be nice, but it's very dark now with sunrise at 8am, sunset at 4pm.

I've noticed the discussion about weather units, which is making me wonder whether I should acquire some new kit for mine - it's always in full shade and against the garden wall away from the house so that I always have an exposed shade temperature, yet I consistently record some of the lowest high temperatures in the Manchester area (pretty average for low temperatures).  Mine's a Netatmo and they have rolled out a "shield" recently - one of those white slotted plastic boxes to go around the unit, keeping direct sunlight off while allowing airflow.  This would allow me to get it away from the garden wall (which, in addition to a little wooden rain roof I built, keeps it in shade) and into air that is heated by direct sun, with a bit more air movement.  I'm guessing that the shade temperature in a position that never gets sun is colder than the actual air temperature where the sun is doing its work - which is the real temperature after all.  What do you reckon @RedRabbit, anyone?
