A deepening storm system pulling away from the region Sunday night and Monday will combine with incoming high pressure to yield an extended period of very strong winds Sunday night through Monday night.
While winds will pick up Sunday and Sunday night (from the southeast Sunday morning and then from the west and northwest Sunday night), the peak of the event looks to be during the day on Monday.
Expect ongoing wind gusts of 40 to 50 mph throughout the daylight hours and numerous gusts over 50 mph across the region. It would not be surprising to see several locations record peak wind gusts to 60 mph at throughout the day.
Model guidance shows a very unstable low level environment in the sky, which will be capable of tapping strong winds blowing aloft and mixing them downward to the surface. A “good” signal for strong wind is seeing 925 mb winds (that’s about 2000′ above the ground) blowing at 40 knots (46 mph) with a mixing layer that extends well beyond that height – to 5000+ feet (where winds will be howling at 60 knots).
