Latest Aviation Discussion:
.AVIATION /06Z SUNDAY THROUGH THURSDAY/... Conditions are VFR at the terminals early this morning, but ceilings are expected to drop to MVFR as showers and potentially a few thunderstorms associated with a cold front approaching from the west move through. For now the thunderstorm potential has been highlighted in the TAFs with PROB30 groups, but if confidence in their occurrence increases, TEMPO groups may be introduced. Winds are currently gusty out of the south, but will shift to the west and then northwest as the front moves through. Improvement back to VFR conditions is expected this afternoon, as northwesterly winds gust to around 20-25 knots. VFR condtions will then persist through at least the middle of the week. Breezy to windy conditions expected today through Tue with gusts to 30 kt, mainly during the daylight hours. Winds begin to diminish Wed afternoon.
