WHAT HAS CHANGED

Refreshed the aviation section for the 00Z TAFs.

KEY MESSAGES

1. High pressure remains in control for the rest of the week into the weekend with little to no precipitation on the horizon.

DISCUSSION

KEY MESSAGE 1 DESCRIPTION...

Models remain in good agreement that high pressure will dominate the weather pattern over the Northeast into the weekend. This will provide fair weather for the rest of the week with day time highs near normal and cooler nights thanks to radiational cooling. A cut off low offshore of the Mid Atlantic will meander well southeast of New England through Wednesday. A NE gradient will tighten at times between this system and the high centered NW of of New England bringing periods gusty NE winds near the coast and building near shore waves. By Thursday into the Friday the low will pull east away from New England with a strengthening northerly gradient. This could lead to a couple of breezy days Thursday and Friday when winds could gust 20-30 mph. High pressure then moves close to overhead going into the weekend allowing winds to slacken.

AVIATION /00Z TUESDAY THROUGH SATURDAY/

Through Tuesday: Light winds and clear skies tonight should allow valley fog to develop and produce IFR to LIFR and LEB and possibly CON. Another area to watch for fog and low stratus is the PWM-AUG-RKD corridor, but since this is lower confidence have only introduced MVFR restrictions at PWM and AUG. This potential should be largely over by 14Z Tuesday with VFR the rest of the day. N/NNE winds will gust 15-20 kt from late Tuesday morning into the afternoon.

Tuesday Night: Mainly VFR conditions with NNE winds of 10-15 kts. However, winds may be light enough for valley fog at LEB.

Wednesday/Wednesday Night: VFR conditions with NE winds of 10-15 kts.

Thursday-Friday: VFR conditions with NNW winds of 15 kts gusting to 25 kts.

Saturday: VFR with light winds.

MARINE

The gradient between high pressure to the NW and a nor'easter off the coast of the Carolinas will tighten tonight with NNE winds gusting to 25 kts at times early Tuesday morning into Wednesday along with building seas. This nor'easter will lift northeast later this week but is expected to remain south and east of the waters. As the nor'easter pulls east N to NW winds will gust 25 to 30 kts Thursday night into Friday with Gales possible over the outer waters. High pressure moves closer overhead Saturday allowing winds to slacken.
