690 FXUS61 KGYX 210704 AFDGYX Area Forecast Discussion National Weather Service Gray ME 304 AM EDT Mon Sep 21 2026 .WHAT HAS CHANGED... No significant changes to the forecast this early Monday morning. && .KEY MESSAGES... 1. Fair and dry weather will dominate early this week with frost possible at night. 2. There is a signal for a slow moving coastal system near the East Coast late in the week. Impacts will be track dependent, which remains uncertain at this time range. The potential exists for rain, gusty NE winds, and high surf sometime over next weekend. && .DISCUSSION... KEY MESSAGE 1 DESCRIPTION... After some early morning low clouds and fog, confidence is high that fair weather will prevail today through at least Wednesday. Broad high pressure over southern Canada will be the source of this fair weather as it drifts east through the week. As the high remains centered north of the area, temperatures will trend cooler than normal for both day time highs and overnight lows. This will translate to highs in the low to mid 60s and lows in the 30s to 40s. There will likely be favorable radiational cooling conditions most nights and it is likely some spots south of the mountains will see some frost. KEY MESSAGE 2 DESCRIPTION... At the end of the week, models have consistently shown the potential for a coastal low to impact the region. A high degree of storm track uncertainty still remains, but the low could allow for some much needed rainfall over the weekend if the low takes a more westerly or northerly track. Gusty winds and high surf could be possible as well. && .AVIATION /08Z MONDAY THROUGH FRIDAY/... Through 06z Tuesday: Mainly VFR outside of nighttime valley fog. Any low clouds and fog early this morning should lift with increasing north winds, lingering across the mountains and CT River Valley. Valley fog may return again overnight into Tuesday. Outlook: Tuesday-Wednesday: Mainly VFR with no sig wx. Thursday-Friday: Mainly VFR outside of nighttime valley fog. Some increase in winds and showers possible late Friday and Friday night. && .MARINE... High pressure will remain centered north of the waters through mid week while an area of low pressure develops offshore of the Mid Atlantic. Winds and seas likely remain below SCA thresholds into Tuesday. A strengthening NE gradient will bring potential for periods of SCA conditions Wednesday and Thursday and potential for Gales late in the week depending on the track of the low pressure system. Regardless of track, seas will likely build in excess of 5-7ft around Thursday and continue to build into the weekend. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...None. NH...None.
