Good morning, this morning is even colder than yesterday in Guatemala, Honduras and El Salvador. A new high pressure is expected to build and bring a new surge of cold air to the region on the next few days so the cool pattern is not going to move from here yet. The lows this morning:

Belize city (Belize) 19°C (66°F)
Guatemala city (Guatemala) 10.2°C (50.4°F)
Quetzaltenango (Guatemala) 5.6°C (42.1°F)

Wow, really low temperatures.
And I thought I was cold here

[vbhoutex]

Wow, really low temperatures.
And I thought I was cold here

msbee what temps do you get down to where you are? A lot of those temps he is reporting are in higher elevations. Are you at a higher elevation where you live?

[cycloneye]

Some locations with record lows in Puerto Rico for December 5th: Aibonito is located around 1500 feet up in the mountains and that is why always is the most lower reading temps.

Yep, that's true the coldest readings are from locations of 2000 m (6500 ft), Guatemala city is at 1500 m above sea level (5000 ft) and Tegucigalpa and San Salvador are at 900 m (2900 ft) and 600 m (2000 ft) respectively.

msbee what temps do you get down to where you are? A lot of those temps he is reporting are in higher elevations. Are you at a higher elevation where you live?

I'm just joking about being cold.
It is just gorgeous weather here with a nice tropical breeze and "cooler" temps.
That means temps around 80 degrees instead of 90 degrees.
We in the Caribbean get cold at night though when the temps fall to maybe somewhere between 77-79 degrees

[chrisjslucia]

We in the Caribbean get cold at night though when the temps fall to maybe somewhere between 77-79 degrees :lol

So true! I used to scoff at this notion but last week I had to put on a long sleeve jumper to go out one evening!

[Hylian Auree]

Yeah, it's been relatively cold lately. I haven't had to use the AC for weeks now!
Currently raining again, though. :|

Welcome to the thread for the members who live in the whole Caribbean Basin and in Central America. Here,you can post weather observations from where you are,of course, when you can.If you have web cams that you know of over there,post them and I will add those to the long first post of this thread where there are many cams from different islands.

The San Juan discussion that was supposed to come out this afternoon,didn't do so because of an outage.All appears resolved so here is the night discussion.


AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SAN JUAN PR
1017 PM AST SUN DEC 5 2010

.SYNOPSIS...A BROAD POLAR TROUGH WILL DOMINATE THE WRN ATLC OVR
THE NEXT SEVEN DAYS. THIS TROUGH WILL FAVOR THE NWD AMPLIFICATION
OF AN INVERTED TROF ACROSS THE REGION.

&&

.DISCUSSION...AIR MASS REMAINS PRETTY DRY WITH PW VALUES STILL
LESS THAN AN INCH. BLENDED TPW IMAGERY ALONG WITH 0-3 KM GFS
WINDS DO NOT SHOW ANY SIG MOISTURE ADVECTION OVERNIGHT INTO THE
LOCAL AREA. RADAR IMAGERY SHOWS ISOLD SHOWERS OUTSIDE OUR CWA BUT
SOME OF THESE MAY ADVECT CLOSER TO THE USVI TOWARD DAWN AS
MOISTURE ADVECTS WWD. STILL NOT MUCH EXPECTED TOMORROW AFTERNOON
AND SHRAS IF ANY WOULD STILL BE ISOLD.

MOISTURE INCREASES RAPIDLY MON NIGHT AS WAA ENSUES AND WINDS VEER
MORE TO THE SOUTHEAST. SHOULD SEE SHRAS MOVE ONSHORE INTO
SOUTHEAST AND ERN THIRD OF PR. AFTER THIS DRY SPELL SHOULD FINALLY
SEE AFTERNOON CONVECTION DEVELOP TUE AFTERNOON AS AMS BECOMES
UNSTABLE. AN MCS MAY DEVELOP LATE TUE NIGHT ACROSS THE CARIBBEAN
SEA THAT COULD MOVE ONSHORE ONTO SOUTHEAST PR. WED SHAPING UP TO
BE QUITE ACTIVE WITH THE POTENTIAL FOR WIDESPREAD CONVECTION WITH
LOCALLY HEAVY RAINS.

&&

.AVIATION...CONTINUE TO EXPECT PREVAILING VFR CONDS THE NEXT 24
HOURS. LLVL NE WIND FLOW WILL SHIFT AND BECOME MORE EASTERLY
AFT 06/00Z...WITH INCREASING HIGH CLOUDS EXPECTED FROM THE SOUTH
THROUGH THE FORECAST PERIOD.


&&

.MARINE...CWF REMAINS A CHALLENGE DUE TO VERY POOR PERFORMANCE BY
MARINE MODELS AS OF LATE. BUOY 41043 AND 41044 SHOW 7 FT SEAS IN
NE SWELLS THAT SHOULD PROPAGATE THROUGH THE ANEGADA PASSAGE OVERNIGHT.
IT IS LOOKING UNLIKELY THAT NEARSHORE ATLC WATERS WILL SEE SEAS
GREATER THAN 6 FEET.

DEEP LOW ACROSS THE NW ATLC SHOULD GENERATE BIG NW SWELLS THAT
SHOULD ARRIVE INTO OUR WATERS AT THE END OF THE WEEK. WHILE I HAVE
CONFIDENCE THAT NW SWELLS WILL EVENTUALLY GET HERE AM NOT SO SURE
ABOUT THE NE SWELLS THAT THE MODELS ARE INDICATING FOR THE END OF
THE WEEK AS THE LOW PRES GENERATING THESE SWELLS IS FILLING/WEAKENING.


&&

.CLIMATE... A RECORD LOW TEMPERATURE OF 67 DEGREES WAS SET AT CYRIL E. KING
AIRPORT/USVI TODAY. THIS BROKE THE OLD RECORD OF 69 SET IN 1989.

.PRELIMINARY POINT TEMPS/POPS...

[BZSTORM]

chilly day again in Belize...lots of gray skies and drizzle ... not my kinda weather
BZ Met forecasting another cold front to move in on tuesday so not much chance of warming up a bit b4 then.
Have a question anyone know why NHC is still issuing tropical weather discussions (I'm on milaing list) Last year they stopped on Dec 1st so was currious that I'm still getting them in my mailbox - don't get me wrong info in them is very interesting but just finding is unusual.

[Macrocane]

It's interesting the diversity of opinions that we have on this board, you want to warm up but I want to stay cool. Some differences between the effects of the cold fronts in Belize and El Salvador is that Belize gets some rains and cloudy skies but El Salvador gets sunny skies and cooler temperatures.

By the way, the TWD are issued the whole year so I guess you are going to have them every day even if the hurricane season is over though I don't know if they mail them the whole year.
