KEY MESSAGES

- Scattered Shower chances Wednesday with more widespread rain Friday into the weekend.

..Winds Tonight

A cold front already starting to push east over wester ND will arrive later this evening and increased CAA 925MB will result in dry adiabatic mixed layer off the surface. While there may be a shallow nocturnal inversion, pressure rises and strong CAA at 925MB should help create at least a period of stronger winds from the west then northwest as the front passes. Winds near the top of the mixed layer may be near 50kt over parts of the Devils Lake Basin, and this raises the potential for a few localized gusts 58mph+, though more frequent gusts with the period of stronger winds would be 45-50mph. Due to the direction of the winds and orientation of unidirectional flow through the mixed layer being westerly it is less favorable for stronger gusts east of the Red River Valley escarpment, which matches higher resolution guidance in placement of advisory conditions mainly west of the valley in the 10pm-7am period. There is still potential for a few gusts 45-50 mph farther east or south than the current advisory, however location/duration/coverage are much less certain due to the previously mentioned flow/wind direction. It will be something to monitor in the event we have to expand the advisory based on trends this evening.

AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/
