Need I say more! An extremely powerful low pressure system moved eastward earlier this week and now the remnants of the cold upper level trough is finally moving through. But I'm sure everyone is wondering why is it snowing in April? Well, here's your explanation:
When you get really powerful low pressure systems they eventually gain enough power and energy to develop into the upper levels of the atmosphere. When this upper level low develops, storm systems usually have the signature "occluded" (the pink/purple front on weather maps) frontal boundaries. Occluded fronts develop when the cold frontal boundaries catches up to the warm front. Once the occlusion occurs the surface low continues to move in whichever direction the system is prepelled in while the upper level low lags behind and pulls extremely cold area around on the westward side of upper level low. This is exactly what we are feeling the effects of. The amazing thing is that the surface low center of this system is already off the east coast while the upper level low is still hanging around the Great Lakes area! This really shows how occluded this system became.
This weekend will continue to be cold until this upper level low pushes off to the east. Sunday will be cloudy, just as today was. Expect to see more snow and rain showers through the early afternoon Suday. Monday sunshine will return and tempertures will continue to rebound into the early portion of next week.
Stay warm friends!
Anthony
