Southerly flow throughout the rest of the day today.

Westerly flow on Monday. 12 run of the NAM is showing only a slight decrease in wind speeds in the morning tomorrow. Wind speeds at 200m at about 10am are modeled to range from 3-5m/s, and modeled wind speeds seem to be consistently underestimated. I would put actual wind speeds around 4-8 m/s. Bufkit is showing the boundary layer height to grow to 8.5km by midafternoon, which is unreasonably high and clearly an error, but verifications show that this is usually a sign of a fairly large amount of convective instability (which leads to vertical motion) that reaches fairly high up. I would guess it should be fairly turbulent on site tomorrow, especially by 2 or 3 in the afternoon.

Southeasterly flow on Tuesday as strong low pressure centered around Wisconsin and Minnesota reaches down to New Mexico. Cold front may sweep through the area on Tuesday afternoon which should bring more cold air from Canada. On Wednesday morning high pressure will make its way back into the area with a more southerly flow turning more southwesterly in the afternoon with very light wind speeds.  Northeasterly flow on Thursday shifting to southeasterly on Friday as high pressure dominates much of the U.S. On Saturday low pressure will move into the area again which should bring faster northwesterly flow.
