Area Forecast Discussion . UPDATED National Weather Service Gray ME 629 PM EDT Mon Aug 10 2020

SYNOPSIS. Warmer and increasingly humid air will persist through Tuesday. A cold front slowly approaches through Tuesday, allowing a few showers and thunderstorms to develop. That cold front will cross the area Wednesday . with a bit less heat and humidity to follow for Friday and the start of next weekend.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. 625 PM Update . Adjusted PoPs and weather grids to cover convection arriving from the west. At this time the cells are weakening as they approach from VT, but have kept isolated thunder in. These are developing along and ahead of a couple weak boundaries, one a stationary boundary to our southwest and the other a warm front poorly defined at the surface to our west. As such, we may see activity continue overnight. This will mainly be over the mountains as orographic processes combine with weak waves aloft to provide some additional lift.

Temperatures were adjusted to match the latest ob trends. Fog was also added for the waters overnight. The heat advisory for central/south NH and interior western ME Tuesday remains unchanged at this time.

Previous discussion . It has been a quiet afternoon with the exception of a few isolated showers over northern and eastern portions of the CWA. Any convection should continue to diminish as we head into the evening and overnight hours. Much like last night, areas of patchy fog will be possible in the valleys early Tuesday morning as low temperatures only drop into the lower 60s in the mountains and the mid 60s to near 70s elsewhere.

SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/. There are two main concerns tomorrow: widespread heat and humidity and a chance for showers and thunderstorms.

Will start with the heat as tomorrow should be the warmest day of this most recent stretch of hot and humid weather. Broad high pressure over the eastern U.S. will allow temperatures to rise into the lower to mid 90s Tuesday afternoon with dew points in the upper 60s to lower 70s. This will lead to heat index values above 95 degrees for much of the region and a heat advisory has been issued for those areas. Some locations, particularly in southern NH, will see maximum heat indices closer to 100 degrees. There is admittedly some potential for lower values depending on how convection develops early tomorrow afternoon.

A cold front approaching from the west will provide weak forcing for shower and thunderstorm development beginning in the late morning/early afternoon. The best chances will remain in the mountains where additional forcing from terrain will aid their development, but this activity could provide some temporary relief from the heat in the afternoon and early evening.

As the front nears Tuesday night, we will see continued chances for showers and perhaps a few rumbles of thunder, but again the bulk of this activity will occur over the higher terrain in northern zones.

LONG TERM /WEDNESDAY THROUGH MONDAY/. Overall looking like a fairly quiet extended period coming up. The cold frontal timing on Wed looks to be too early to really capitalize on peak instability and so showers and thunderstorms are expected along the front . widespread strong storms are not anticipated at this time. Temps could make a run for the 90s ahead of the front . and given the dewpoints in the low 70s the heat index values may reach 95. This will be especially true along the coast.

After that the upper trof will swing thru on Fri . and very seasonable temps and humidity is expected for the weekend. Little in the way of precip is expected however . which will exacerbate lingering drought issues.

AVIATION /22Z MONDAY THROUGH SATURDAY/. Short Term . General VFR conditions at all terminals through the short term. Possible brief MVFR/IFR conditions at terminals affected by any SHRA/TSRA, most likely at HIE/LEB.

Long Term . Generally VFR conditions expected thru the remainder of the week. Local MVFR or lower conditions are possible in SHRA/TSRA along the cold front Wed.

MARINE. Short Term . No concerns through Tuesday other than the possibility of an isolated shower or thunderstorm Tuesday afternoon. Winds and seas build over the outer waters Tuesday night ahead of a frontal system.

Long Term . Winds and seas expected to remain below SCA thresholds. Some areas of fog are possible along the coastal waters Wed morning and possibly again Wed night ahead of the cold front.

GYX WATCHES/WARNINGS/ADVISORIES. ME . Heat Advisory from 10 AM to 8 PM EDT Tuesday for MEZ012>014- 018>021-033. NH . Heat Advisory from 10 AM to 8 PM EDT Tuesday for NHZ006>013- 015. MARINE . None.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
