The Arctic air that was previously over eastern Asia has now rotated around to invade North America. However a west to east High Pressure ridge is sort of blocking the cold from pushing down into Central America keeping Belize fairly warm. There is just some mid level cloud being carried up from the southwest with just a few sprinkles of rain here and there.

Sunday, December 28, 2014

The coldest Arctic air continues to circulate over to Europe and Asia. Europe is having terrible weather right now. The Upper Air wind speed over Russia is over 300 kph.
Here in Belmopan we had 25 mm of rain last night due to the moist air flow being transported up from Honduras. However this morning dry air has returned and it is warm and sunny. The system responsible for the circulation is a strong High Pressure centered at 24.0 N 78.6 W or off the north coast of Cuba.

Saturday, December 27, 2014

There is an area of moisture in the Gulf of Honduras this morning due to some warm moist air flowing up from the coast of Nicaragua. This resulted in some light rain overnight and a few showers this morning. The air flow can be seen in the image below, the white patches are areas of showers.

Friday, December 26, 2014

 High Pressure just off eastern Cuba is keeping the Caribbean clear this morning. The was a trace of rain overnight in Belize. The cold front is weakening and will be gone tonight. North America is relatively mild compared to Asia as seen in the Upper Air Polar winds at the 10 mb level. Northern India is unusually cold with heavy snow.

Thursday, December 25, 2014

Light rain developed overnight and measured 0.58 in or about 14 mm by noon of today. The band of showers has stalled off the Belize coast as the hot dry air is attempting to push westward. So now there is a battle going on between the cold air and the hot. Will see who is winning in the morning. The cool rain last night was great for the garden.

Wednesday, December 24, 2014

The wind shifted to the North at 8:25 PM local time indicating the passage of the Cold Front. There is only high thin cloud so no rain at all. The Caribbean remains extremely dry. The cold front will likely have little affect on Belize weather. Just a little cooler at night for the next few days.

The position of the cold front is now clearly visible in the surface wind image. The front should begin to cross through Belize sometime after sunset. Not sure if this will produce any rain at this time.

Tuesday, December 23, 2014

Belize is between a band of high cloud to the north and west and very dry air to the south east. There is a cold front that is currently moving off the coast of Texas and beginning to cross the Gulf of Mexico. The cold front is expected to be close to Belize by Wednesday night. Will follow the progress. The whole Caribbean is very dry.

Sunday, December 21, 2014

There was no rain at all from the system mentioned in the last report. The system went north missing Belize completely. Late this afternoon some high cloud moved across Belize from the southwest. The Caribbean basin is very dry. According to the Caribbean Climate Change group (the CCCCC) the coming dry season may be very severe. There could be very little rainfall over the next 5 months. This is not good news. Here in Belize the 2014 rainfall is already well below normal. I may have to abandon plans for having any sort of productive garden.

Friday, December 19, 2014

Most of the moisture associated with the weak trough of low pressure east of Belize appears to be moving up to the northwest and bypassing Belize completely. The bottom end of the trough may sweep towards Belize in the morning producing some light rain but I expect no more than an few mm, not enough to bring relief from the very dry conditions.

Thursday, December 18, 2014

The weather here in Belmopan has been sunny and cool since my last report. It has been very dry. Rainfall is well below normal. Plants in my garden are already suffering due to lack of rain. There is a weak trough creeping slowly westward towards Belize. It is surrounded by very dry air. Will see how this looks in the morning.

Sunday, November 30, 2014

Light rain is falling right now as a low level weather system moves westward towards Belize. The problem is that this system is fighting a very strong upper level wind shear shooting across Belize from west to east. This could limit the amount of rainfall from this system. The red colour indicates that there is very little convection in this this system.

Tuesday, November 25, 2014

A Cold front is presently approaching Belize.
The pre-frontal storm cells are moving from south to north. Not much rain associated with the front at the moment. Will see what this weather looks like in the morning. The main front is not supposed to arrive until tomorrow morning after sunrise.

Wednesday, November 19, 2014

A Cold Front has crossed Belize and has become more or less stationary in the Gulf of Honduras.
Light Rain has been falling all evening and continuing into this night. There is a cool north wind blowing. This stationary front is suppose to become diffuse Thursday morning.

Sunday, November 9, 2014

There is a Cold Front moving across the Yucatan that may affect Belize tonight. This keep the weather in Belize cool and dry for the next few days.

Saturday, November 1, 2014

A weak cold front passed though Belize last night with a cool north wind. A stronger cold front is now just approaching the northern Yucatan. This cold front should reach Belize tonight. There is not much rain associated with these fronts.

Wednesday, October 29, 2014

The moisture from the remains of Hanna drifted to the northwest to a position off the coast of Belize where the system gradually dissipated. Over the past 24 hours here in Belmopan we received 111.0 mm rainfall. Right now at 7:20 PM the sky is clearing and the moon is visible.

Monday, October 27, 2014

 Tropical Depression 9 has turned into Tropical Storm Hanna and is now located at 15.4 N by 82.8 W The storm is forecast to move south west and then dissipate over land. Heavy rainfall expected over parts of Honduras. Not sure what affect will be on Belize yet.

Sunday, October 26, 2014

The recent Tropical Depression 9 now just a weak Low is still active and now located off the east coast of Honduras. It is embedded in the tail end of a cold front. This Low is forecast to drift SW into Nicaragua. The weather in Belize very pleasant at the moment due to the passage of the Cold Front.

Friday, October 24, 2014

The Tropical Depression ( called TD9) described a few days ago failed to developed and collapsed into a weak Low Pressure. This Low was absorbed by a cold front over the northern Yucatan and moved off to the east towards Cuba. In Belize at my location in I measured 0.82 inches of rain last night due to a moderate shower. Today is just cloudy with a light northerly breeze. Most of the Caribbean is experiencing fair weather.

Tuesday, October 21, 2014

A tropical depression is developing in the southern Gulf of Mexico and is drifting to the east towards the Yucatan. This is going to create some unsettled weather for Belize over the next few days. Will be following this system for further developments.

Monday, October 20, 2014

I was traveling in September and first part of October so was not making any daily contributions to this weather blog. I do know that there were frequent showers during this period resulting in a six week rainfall of about 13 inches in September plus 8 inches up to this time in October. The ground is fairly saturated with moisture as a result of the rainfall in combination with cloudy skies and relatively light wind which did not contribute to any significant evaporation. All this is in contrast to the abnormally dry weather during the months of June, July and August. Overall the weather has been fairly uneventful due to the lack of Hurricanes or other violent weather in this region of Central America.

Sunday, August 31, 2014

Tropical Wave now in the process of crossing Belize.
Rain started in Belmopan at 1235 Hr. There is an upper wind outflow at 17.5 N, 83.9 W. The wave is moving westward at about 20 mph. I expect about 18 mm of rain from this wave since the cloud tops are collapsing.

Saturday, August 30, 2014

The weather has been mostly sunny and warm for since my last report with a few showers on the 28 and 29 with only about 12 mm of rain. But right now there is a more active area of weather located around the area of 18N and 83W which is drifting towards the Yucatan. The system is not very well organized. Will check on this later today. In general, the Tropics is fairly quiet. Not much activity World Wide according to Jeff of W_Underground. Unusual for this time of year.

Monday, August 25, 2014

There has been no weather activity since my last report. Just hot dry weather every day. There is a large mid level High Pressure centred just north of Cuba's western tip. This is causing a hot and dry south easterly air flow across Belize. No rain in sight until perhaps late in the week.

Saturday, August 16, 2014

There is an Upper Level Low at 19.5W, 82.4W which is south of Cuba and west of Jamaica. An area of rain is heading west towards Belize. This should arrive this afternoon sometime. There have been already a few showers in Belmopan this morning. The nights of August 13 and 14 tropical waves passed with lots of thunder and lightening. Provided a combined rainfall of 36 mm. The storms developed rapidly overnight and lasted about 3 hours each. The next tropical wave is currently in the eastern Caribbean.

Wednesday, August 13, 2014

Weather activity in the Caribbean is very low. The area is dominated by very dry air. Rainfall for Belize is well below normal.

Friday, August 8, 2014

A new Inverted Trough lies to the east of Belize in the Gulf of Honduras. Most of the moisture ls found to the east of this trough. The band of moisture is moving slowly to the west. Will check on this system in the morning.

Wednesday, August 6, 2014

Another Inverted Trough has formed off the east coast of Belize. However, this one has less moisture except for an area in the north east corner of Honduras. There is not much chance of any significant rainfall until after the weekend with the approach of a Tropical Wave.

Tuesday, August 5, 2014

The Wind Shear across the Caribbean has become much more chaotic compared to a few weeks ago. The zonal dry season wind pattern seems to have been disrupted. This could indicate much more unstable weather ahead. The low pressure trough mentioned this morning caused an explosion the thunder showers inland over Belize around 1PM. I measured 12 mm of rain.

There is an Inverted Trough to the east of Belize extending up to the western end of Cuba. An area of convection lies to the west of this trough. Belize should experience a few thunder showers over the next 24 hours. This will be followed by sunny and hot weather again.

Sunday, August 3, 2014

An Upper Air Low has drifted westward and now is located at 18.4N, 88.8W which is the northern region of Belize. This low is circulating Hot and Dry air across the central part of Belize. There is a broad Tropical Wave passing through the Saharan Air Layer. This wave could begin the affect Belize sometime later this week. Will keep a watch on this one.

Monday, July 28, 2014

A tropical wave has intensified over Central America p[producing frequent showers with some thunder. Have measured 29 mm rain since last night. The main storm centre is over Honduras. Weather should clear after this system passes. There is a small upper low over Jamaica.

Friday, July 25, 2014

There is currently a band of moisture stretching across the mid section of Belize. This is resulting in a Thunder Shower taking place between 2000 and 2030 local time. To the east there is a tropical wave at 84.1W from 22.5N down to 10.0N with a 4 way convergence at 17.9N, 81.2W as noted by the 250 mb wind flow. There may be some unsettled weather tomorrow due to the TW before the dry returns.
This morning Spaceweather report "STRANGE SITUATION: In the middle of Solar Max, the sun has slipped into a state that resembles Solar Minimum. Sunspot numbers are low; the sun's X-ray and radio output are depressed; and NOAA forecasters estimate a scant 1% chance of solar flares during the next 24 hours."

Thursday, July 24, 2014

The Saharan Air is like a fiery dragon devouring any moisture headed this way. The rainy season may be over for now. And up in the central part of North America another outbreak of polar air is ready to invade making it fell more like October rather then the end of July. “NWS Cleveland, Ohio, says the overall pattern is like what we saw over the winter time (and is more typical for winter, not summer),”

Tuesday, July 22, 2014

There is a CCW upper air circulation centred at 16.4N 78.0W which is a region south of Jamaica. This is associated with a Tropical wave. However, there is very little moisture associated with this system. The water vapour all the way east to Africa is lower than normal for this time of year. The Saharan Air Layer is still a dominant factor in the Caribbean. There is an upper air Low at 6N 42W which I need to keep watching for the next few days.

Saturday, July 12, 2014

The Upper Level CCW circulation has shifted to the west and is now located at 19.5 N and 81.7 W this has pushed the tropical wave just passed Belize and is now crossing Guatemala. The storm cell on this wave expanded rapidly this morning producing a series of thunder showers over Belize, mainly south and central. Have measured 12 mm of rain due to this wave. The rainfall was limited due to the fact that the air feeding down from the north was fairly dry. The next wave due in 2 days could produce greater rainfall.

Friday, July 11, 2014

The Saharan Air Layer is becoming more fragmented. The real rainy season may be getting ready to arrive. There is an upper air CCW circulation near the eastern end of Cuba. However it is nor carrying that much moisture over Belize as yet. Moisture is indicated by the blue colour. We should start to see an increase in moisture over Belize sometime Sunday.

Monday, July 7, 2014

A weak tropical wave is approaching and is now just reaching the eastern end of Honduras. Belize may experience a few showers from this wave tomorrow. Thereafter,

Friday, July 4, 2014

The rainfall in Belmopan early last night was measured to be 2.7 inches or 68 mm Belmopan appears to have received more rain than the surrounding areas. The tropical wave had passed well to the west by midnight. Today was mostly sunny with fair weather clouds. The Caribbean basin is mostly dry with the Saharan Air Layer covering most of the eastern region.

Thursday, July 3, 2014

The Tropical Wave has become very active this evening. A storm cell is passing very close to Belmopan right now and producing a significant rainfall. Will give the measurement in the morning.

A Tropical Wave is passing through Belize at the moment. The wind shear has become very light allowing an increase in convection. A thundershower is occurring right now at 10:15 this morning. However, to the east of this wave the area is still dominated by a large Saharan air mass as shown in the TPW image. Therefore, once this wave has passed, Belize should be right back into dry air again.
