Mid week into next weekend, The next front is forecast to push offshore, with the potential for multiple weak lows/waves of low pressure to travel along this front mid-week, which may bring the next chances of rain to ENC. There is a building signal that a stronger low pressure system will then move across the region Thursday bringing additional chances for precipitation. Guidance continues to struggle with the strength, timing, and location of the system, but there is potential (10-30%) for a changeover to a wintry mix or snow as the system pulls away from the coast Thursday night, but it is still too early for any discussion on impacts or accumulation potential.

- Very gusty NW winds rest of SUN, crosswind concerns for SW-NE rwy
VFR flight cats expected through the TAF period with gusty winds being only concern. Nwerly winds 15-20G25-30kt forecast for late afternoon until sunset. This will lead to crosswind issues for RWY5 23 at iso and oaj, rwy4 2 at EWN, and somewhat at RWY8/26 at PGV. Winds will decrease to 5-10 knots overnight which will help dry any residual moisture from earlier rainfall and preclude any fog development. Skc in place through MON with significantly lighter NWerly winds becoming SWerly by sunset.
