Its the last day of February and North America is still dominated by Arctic Air. The polar and jet stream pattern has remained virtually unchanged over the entire month. The Caribbean as shown in the water vapour remains extremely dry. The lower images show a cold front as of last night and on the right the same cold front today which has not moved and will now likely just disappear or retreat back to the north as a warm front. Seems like the Earth's weather systems get locked into a pattern and just sit in one place for extended periods of time. This is not a good sign. The planet's atmosphere needs to be dynamic to be healthy.
