| December 4, 2024 Satellite Water Vapor Imagery: A robust upper level disturbance showed up clearly in the water vapor. Such a robust dry presence often correlates to a stratospheric intrusion, which means a deepening weather systems and more influences on weather down to the surface (in this case wind and strong cold air advection). | December 4, 2024 6 P.M. Surface Weather Map: A strong pressure gradient (packing of isobar lines) was present between a deep low pressure of ~991 mb and a modified arctic high pressure of 1038 mb. This helped drive the higher wind speeds, while the circulation around the low pressure oriented the wind direction from the north steering in much colder air. | December 4, 2024 5 P.M. Weather Balloon Data: This observed vertical profile plot shows temperature (red), dew point (green), and wind vectors (yellow). The very strong unidirectional wind field was a favorable setup for gusts to be maximized. The cold air moving in at a faster rate just off the surface steepened the low-level lapse rates aiding in vertical mixing and momentum transfer of strong winds down to the surface. |
