The polar high upper air is allowing the cold arctic air to invade the Middle East. "Bitterly cold weather accompanied by wind, sub-zero temperatures and snow is expected to hit the KSA (Kingdom of Saudi Arabia) on Wednesday and last until Sunday."
North America is fairly normal right now but a new blast of Arctic air is preparing to plunge south in a few days.
The Caribbean is still relatively peaceful. The black region indicates very dry air. Belize had a shower early morning but the day has been sunny and warm. Little change is expected.
