.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/... A strong cold front will bring the return of sub-VFR conditions at times, starting this afternoon and continuing through early Thursday. Showers and strong to severe thunderstorms may impact the terminals during this time. Lots of uncertainty regarding coverage of storms, but if they do develop, they will likely be severe Wednesday afternoon/evening, with damaging winds and large hail being the main threats. An isolated tornado or two cannot be ruled out as there will be plenty of wind shear. Outside of the shower and thunderstorm threat will be the wind. Expect gusty south to southwesterly winds up to 25 kts today switching to the northwest with gusts 25 to 35 kts Thursday afternoon. Expect largely VFR conditions on Friday into Saturday with any precipitation threats to the west of all TAF sites. The bigger story will be the gusty winds on Friday ahead of another strong cold front. Ahead of this system, expect southerly gusts to around 25 to 30 knots before winds shift to west-northwesterly into Saturday and decrease throughout the day.
