The reason that we've had this massive warmup is due to the placement of these high and low pressure systems. On Friday, we had a high pressure system to the southeast and a low pressure system to the northwest. High pressure systems have winds that rotate clockwise around them, while low pressure systems have winds that rotate counterclockwise around them. So once these systems are lined up as they are in the photo, you get a massive channeling of warm air from the south, which has been the main reason for our temperature warmup. However, the reason for our clear and sunny skies can be attributed to the high pressure system to the southeast in the photo. The high has helped to push the low up north, which is why the clouds have continued to move north of us and miss our area.
This trend continues into next week, but the low pressure system moving in from the west will bring us some rain on Monday night. A weak warm front will move through Monday morning increasing our cloud cover, but a weak cold front behind it is what will bring the light accumulation of rain Monday night. Rain is also expected for Thursday afternoon, as another low moves in through our area. There will be a little more rain than what we'll have on Monday, but overall the accumulation will still be light. The rain will filter into the early hours of Friday morning, before clearing out for the afternoon where we will have cloudy skies. The spring-like weather will disappear next Saturday as northwesterly winds move into our area and bring us back down into the 20s, but the majority of next week stays warm with temperatures in the upper 50s to low 60s!
