The total rainfall from last report weather system due to cold front was 70 mm which is quite a lot of rain for this time in the dry season. Now Belize is back in the dry again as seen in the water vapour image. Meanwhile there has been a big change in the polar circulation. The CW loop has become much weaker and moved off to the north and west while the larger CCW loop and now got a double centre and has expanded. This looks like there will be colder than normal temperature for Canada over the coming week.
