The sub-tropical jet is still locked in the same pattern as last night. The double barrelled High Pressure system is diverting the jet straight southward. There is nothing on the horizon that looks like something that will start shifting this pattern.

The sub-tropical jet has made a sharp right turn and is diving south towards Panama. This seems to be caused by a pair of blocking High Pressure cells to the east. There is another High Pressure to the west of Mexico. The result is that the jet is getting squeezed between these cells. With all this high pressure around the chance of any rain is pretty low.

There was rapid change in the weather pattern overnight. The wind shift line approaching Belize completely collapsed. The wind this morning is continuing to flow in from the Caribbean. A powerful winter storm has formed off the east coast of New England (see image). Blizzard warnings are in effect. The Caribbean remains in a zone of very dry air.

A sharp wind shift line is approaching the western boarder of Belize. The air behind the front will likely feel much cooler. Southern Canada and the north eastern part of the US are experiencing some unseasonable cold weather.

The weather has been very dry since my last report but now a new weather pattern is emerging. A late season cold air mass is pushing down from the North. The surface wind down the east coast of Mexico is from the North. In the southern Gulf of Mexico, a weak trough of Lower Pressure is beginning to develop (just to the right of the small circle in the image). Will update this development later today.

The Cold Front trough is over the region with the surface wind pouring down from the North on the west side and up again from the South on the Caribbean side of the image. The wind across Belize at the moment is from the West but will shift to the Northwest as the front moves eastward. The Upper Air is very dry so any rainfall should be limited.

A cold front is just now crossing the east coast of Texas and entering the Gulf of Mexico. There is a squall line out ahead of the front Will check on the position of the front later today. The air in the vicinity of Belize is quite dry so at the moment I don't expect to see much rainfall from this front as it swings across the Gulf.

Interesting weather situation. Belize is right at the point of converging surface winds: North wind flowing down from the Gulf of Mexico, and a south east wind flowing in from the Gulf of Honduras. These two winds are almost cancelling each other so that the winds over Belize right now are almost calm. The air feels very humid and uncomfortable. There is a wind shift line over the southern part of Guatemala where the north and south winds are colliding head on. The cooler north wind is forecast to push a little further south in the Gulf of Honduras then disappear.

The top image shows the position of the Cold Front yesterday (through Texas) and the lower image shows the position a few hours ago diving into the southern part of Mexico. The wind shift lines are clearly visible. The cold front is expected to stall later today and convert into a warm front. Belize should remain hot and dry. The Great Lakes region of North America is experiencing record cold temperatures.
