Friday Morning Weekend Outlook: Unsettled Weather On Tap

Good morning everyone. The good news is we are finally at the weekend. The bad news is it will not be the nicest weekend overall. We have a few rounds of showers to deal with from this afternoon through Sunday night. Saturday looks like it can be spared at this point, but temps will still be in the high 50's to low 60's.

Starting off with today, showers should develop by this afternoon as a upper level short wave spins up the air..


This will be more of a nuisance than anything but it still will keep things feeling more on the damp side.

High pressure then tries to build back in for Saturday which will cause some clearing and temperatures in the high 50's to lower 60's


On Sunday, a stronger more moisture rich low pressure system enters the area causing  scattered showers and eventually a steady rain to develop by Sunday night..


All this should linger through Monday then finally clear out by Monday night into Tuesday.


All this unsettled weather is due to a parade of upper level energy flowing through the area from the north and also from the west. The image below shows this..

Frontal boundaries between warm and cold air develop and as each disturbance in the upper levels move through, it acts to "spin" up this warm and cold air causing unsettled weather and low pressure systems to form.

You can usually see these frontal boundaries by looking for something as simple as the dew point. Why? Well colder air holds less moisture than warmer air. Below I highlighted where this frontal boundary currently is using the dew point..


Again each one of those upper level disturbances I showed before spins this air up causing the rain we are seeing this weekend. 

Thats all for now thanks for reading.
