Loving the warmer Bay Area weather this week? You can thank omega block pattern

SAN FRANCISCO (KGO) -- Can't get enough of the sunshine and warm weather this week? Thank an omega block pattern in our atmosphere.

There are a couple of different types of blocking patterns in meteorology. Think of them as traffic jams in the atmosphere where the weather pattern stays stagnant for a period of time in one area.

An omega block occurs when high pressure is situated near or on top of California. One low pressure system will park itself on the eastern side of the ridge of high pressure and another low pressure system will set up on the western side. This pattern creates a setup which resembles the Greek letter omega.
