Around 1340 hr a large area of rain showers passed through the central part of Belize. Belmopan experienced a fairly heavy rain shower along with gusty winds. There was about 9 mm in 15 minutes. The tail end of the cold front must be stirring up some active weather.

The lower circle is the CW rotation which is continuing to dominate while the old CCW over in Siberia continues to struggle.
The cold front crossed Belize Friday night and stalled east of Honduras. The front is now beginning to dissipate. Since Friday night, here in Belmopan I measure about 52 mm of rain which is pretty significant for this time of year. We don't normally get such a strong cold front this late in March.

A strong Cold Front is approaching the Yucatan. This may bring some significant rainfall to Belize. To soon to determine how much rain.
The CW polar circulation continues to strengthen. Now cemtred at 67.8 N / 117.8 W
Eastern Canada is still unseasonably cold.

The polar circulation is definitely beginning to make a big change. The change seems to be in step with the spring equinox. The winter time CCW pattern is fading away while the summer time CW pattern is beginning to dominate.
The Caribbean continues to be very dry, there is no sing of rain anywhere at this time.

There has been little change in the Caribbean with respect to the low level of water vapour.
However, there is a big change occurring in the polar circulation. The larger CCW rotation is still close to Siberia, while the CW rotation near Alaska is becoming significantly larger. Only the eastern part of Canada is experiencing cold weather.

High cloud from the Pacific side is flowing northward across Belize. Low level cloud is moving in from the Gulf of Honduras across southern Belize but no rain due to the upper air being very dry.
The polar circulation has moved further into Siberia, now centred at 72.2 N / 100.2 E. This is putting the jet stream further north now, more over the Great Lakes and New England. The southern states is now much warmer.

There was some significant showers last night around Belmopan from 0230 to 0430. Measured about 12 mm rainfall. The yellow arrow points at the low cloud system responsible for the rain. The system was amplified by a weak trough passing across the Yucatan.
The CCW polar circulation is continuing to strengthen. Now centred at 86.6 N and 174.8 W and very close to the North Pole. This will produce some below normal temperatures across Canada.

The polar circulation is changing again this time more like returning to a winter time pattern rather than shifting to spring time. The centre is at 84.6 N / 154.0 W. This could mean that North America could plunge back into cold again after a few weeks of milder temperatures.
The Caribbean is still dry. The showers predicted in my last report did not occur.

 There is a cluster of showers moving into the Gulf of Honduras and this may generate a few showers overnight in Belize. There is a cold front cutting across the Gulf of Mexico which will most likely stall and move back as a warm front. I am expecting only about 4 to 5 mm rain in Belize tonight most likely before sunrise.

The Caribbean basin has had a noticeable increase in the level of water vapour. Belize has been experiencing a few light showers during the hours before sunrise. There was 4 mm of rain last night. There has been a significant change in the upper air polar circulation. The CCW rotation is smaller in size and is more in a east-west orientation. This is allowing much milder air to flow across the US and southern Canada.

Friday, March 6, 2015

The southern Caribbean basin is extremely dry (shown as black in the image). The polar circulation is beginning to change. It is swinging off the east coast of Canada. The western side of North America is experiencing warmer temperature and the east is not as cold as it was a few days ago. The record breaking cold may be over for now.
