Warm & Dry Start to Weekend; Chances of Precip Arrive Sunday

Synopsis

Weather will be quite similar to the previous couple of days to start the weekend. We are sitting under a ridge of high pressure between two troughs of low pressure, the resulting weather is warm, fairly humid and overall dry. This will start to change a bit Sunday when enough upper-level energy and uplift will reach the area resulting in chances of rain. These chances of rain will continue into next week which will be discussed in the blog Monday morning.

Analysis

GFS 500 mb (18,000′) vorticity at 00Z Friday (7 PM Thursday)

12 hr forecast from the GFS weather model shows the ridge present over our area with troughs of low pressure to the east and west as labeled in the image. The trough to our west is expected to slowly move into our region going into next week, but in the meantime weather will be uneventful.

GFS 700 mb (10,000′) relative humidity at 12Z Sunday (7 AM Sunday)

By Sunday morning models are in fair agreement with the arrival of a band of moisture associated with warm air streaming in from the southwest. This will bring with it cloudiness and chances of precipitation from the morning to afternoon hours of Sunday. Following Sunday, the weather pattern is a bit uncertain… so expect a new blog on next week’s weather Monday morning!
