Area Forecast Discussion National Weather Service Gray ME 259 PM EDT Thu Jun 20 2024

SYNOPSIS
Heat ridge breaks down this evening as a surface cold front pushes through the area bringing cooler weather.
Front stalls just to our south and becomes a focus for rain shower activity tomorrow and Saturday. Warmer again on Sunday with thunderstorms and locally heavy rain. Quiet weather is expected by the beginning of next week.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/
The backbone of the heat breaks this evening as strong to severe storms move through the region. The heat threat is steadily evolving into a severe threat for this afternoon with a cold front slowly pressing southward through the afternoon hours. Isolated storms are expected to grow and consolidate into clusters and slow moving lines of storms through the afternoon and into the evening. With west- southwesterly flow, storms are not expected to weaken until after they move offshore, bringing the severe threat right to the coastline.

A severe thunderstorm watch has been issued for the entire forecast area, with storms already firing early this afternoon.
Yesterday's storms proved damaging with just high CAPE and cold pools. Today, a little more shear and better forcing from the front combine with the hot and humid conditions to bring severe storms with a higher degree of confidence than we often see.
Damaging winds are likely to be the most widespread impact, but some hail around quarter size is also likely with a few storms, especially in the more isolated ones forming during the mid afternoon hours.

The lines and clusters of storms push offshore through the evening hours after sunset, with much cooler conditions expected behind the storms by late evening. The front slowly moves through during the overnight hours, bringing in drier air overnight. Before this drier air filters in, patchy fog is likely by late evening and into the overnight hours, especially through the valleys and along the coastline.



SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/
The front continues to slowly move through the CWA tomorrow, with temps warming into the mid 80s through southwest NH ahead of the front. Behind the front, cool and dry northeasterly flow keeps temps in the low to mid 70s through much of Maine and the Seacoast of NH. Showers, and some thunderstorms continue near and behind the front tomorrow as moisture continues to ride along the front. This makes for a cool and showery day for much of southern and western Maine and eastern NH. Further behind the front, central Maine may escape most of the shower activity to see more sunshine, with temps warming into the mid to upper 70s accordingly.

Scattered showers continue through the overnight hours tomorrow night as the front lingers to our south. Placed of the cooler side of the ridge, waves of leftover convection and periods of showers likely continue to move through the region as these features ride around the ridge. The cooling trend continues, with lows dipping into the upper 50s to low 60s across most of the area.

LONG TERM /SATURDAY THROUGH THURSDAY/
Overview: Relatively progressive flow after the NE CONUS ridge becomes suppressed with a more active polar jet stream and Canadian troughs moving across New England. Shortwave ridging is expected between the troughs bringing a see-saw weather pattern over the next week. This will bring periods of active weather with thunderstorms and temperature swings from near normal to above normal.

Impacts: Localized heavy rain is possible Saturday across Western NH with a higher threat for localized flash flooding on Sunday across the mountains. In addition, severe weather can't be ruled out Sunday at this time across most of the forecast area.

Forecast Details: On Saturday a stationary boundary will be located in the vicinity of Southern NH with surface ridging to our north.
This will separate the heat and moisture from the Mid-Atlantic and cooler dry airmass from Canada. Expect showers and isolated thunderstorms along this boundary with the highest chances for locally heavy rain across Southwest NH at this time. By Sunday the stationary boundary becomes a warm front and surges north of the area bringing the region back into the warm sector. Threat for severe weather will increase as a robust mid-level shortwave and associated cold front pushes through the area sometime late Sunday into Monday morning. There is some model spread on the order of 12 hours or so on timing of FROPA at this time. Monday the shortwave trough swings through with the potential for much cooler weather and showers, but this depends on the timing of the trough. Tuesday looks to have the highest potential for being the driest day of the week as a shortwave ridge moves over the area with a rebound in the temperatures. Wednesday could be warm once again as a return to southwest flow is possible ahead of the next approaching trough. A period of storms is possible in the Wednesday night into Thursday timeframe as the next cold front swings through the area.

AVIATION /19Z THURSDAY THROUGH TUESDAY/
Short Term...Showers and occasional thunderstorms are expected at all terminals through the afternoon to early evening hours, occuring first across western terminals and moving to the coastal terminals by the late afternoon/early evening. These storms push offshore by late evening, with brief periods of BR or FG possible in the valleys overnight. PROBs are too low to go too strong with the fog threat, but IFR to LIFR can't be ruled out late tonight at LEB, HIE, and RKD. Conditions improve tomorrow morning, but periods of MVFR ceilings are likely through coastal terminals. Showers and brief restrictions are possible at all terminals tomorrow afternoon and night, but otherwise mainly VFR to occasional MVFR conditions are expected.

Long Term...Showers and thunderstorms could bring temporary MVFR to IFR conditions on Saturday with the highest threat across the airfields of New Hampshire. Similar impact to operations is possible on Sunday as the threat for afternoon thunderstorms increases along with gusty southwest winds. Storm coverage should trend downward by the beginning of next week.

MARINE
Short Term...A cold front slowly moves southward across the waters overnight tonight and tomorrow. Thunderstorms with strong wind gusts are likely near the coast late this afternoon and early evening. Winds shift to northeasterly behind the front tonight, but conditions are expected to remain below SCA levels through tomorrow night.

Long Term...Storms are possible over the waters on Saturday. By Sunday strong SW winds could develop leading to marginal SCA conditions by the afternoon and evening hours ahead of an approaching cold front.
Cold front pushes through on Monday with a return to offshore flow and possible SCA conditions.
