Area Forecast Discussion . UPDATED National Weather Service Gray ME 1126 PM EDT Fri Jul 10 2020

SYNOPSIS. Tropical storm Fay crosses well west of our region tonight into early Saturday. Showers will overspread the region tonight with showers and scattered thunderstorms on Saturday. An upper level trough crosses the region Sunday with a second trough arriving for the first half of next week. This will lead to more scattered showers and thunderstorms, mainly during the afternoon and evening hours.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. Update . No major changes to the current forecast.

Previous discussion . High Impact weather: heavy downpours overnight as Tropical Storm Fay moves west of the area.

At 3pm Tropical storm Fay was located just east of Cape May, NJ moving north. This is a fairly compact storm with the cirrus cloud shield extended to southern New Hampshire with rain bands into Long Island. As the storm move north this afternoon a expect rain to move into southern New Hampshire round sunset and through the rest of the area by morning.

The fog that's been present the past few nights remains lurking just offshore, and expect it to move in again tonight, especially along the midcoast where the rain will be last to arrive. Have issued a Dense fog advisory from Portland east, with patchy fog expected elsewhere.

While the storm center will stay well to our west up the Hudson valley, easterly flow into the White moutnains will make for a local maxima in rainfall near Fryeburg with around 1-2 inches expected in the foothills of the white moutnains.

Forecast soundings, as well as morning observations to our south from KOKX show a very deep warm saturated layer. This will help to produce very efficient rainfall, which may lead to localized flash flooding if storms remain in one location. With the threat isolated to individual cells in a small area, have opted not to issue a Flash Flood watch at this time although some flash flooding is possible.

SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/. The bulk of the precipitation will move through overnight. By mid morning tomorrow, some sunshine will break out across southern New Hampshire. This will have two effects. First, to raise the temperature, which, in combination with the humidity will once again push heat index values to the mid 90s heat advisory criteria. Expect this maximum heating to be short lived as that same sunshine will also destabilizes the atmosphere allowing for scattered thunderstorms to form. These storms will once again be expected to produce very heavy rain with localized flooding possible.

Rip Risk: The combination of building nearshore waves into the 4 to 7 foot range and onshore winds of 10 to 20 mph will allow for the increased threat of rip currents. This may be problematic as the warm/humid weather conditions on Saturday may lead people to the cooler beaches. Have advertised this in our DSS product suite.

LONG TERM /SUNDAY THROUGH FRIDAY/. We continue to transition from a very dry weather pattern to numerous chances for precipitation for this upcoming week .

On Sunday, a trough of low pressure and its accompanying cold front will cross the region. This will trigger more showers and scattered thunderstorms. The atmosphere will still be filled with rich, tropical moisture, so some of this precipitation may be locally very heavy. H8 temperatures around +18C will allow for temperatures to climbed well through the 80s with the exception of cooler conditions along the coastline due to a breeze of the Gulf of Maine. Surface dew points will remain very high, topping out near 70 degrees in some areas.

On Monday and Tuesday, yet another upper level disturbance will enter the region from the west. This will allow for more showers and scattered thunderstorms. These will be diurnally enhanced and mainly during the afternoon and early evening hours. As the upper level low parks itself overhead on Tuesday, slightly cooler temperatures can be expected with afternoon highs dropping into the 70s to mid 80s. Highest temperatures will be over southern New Hampshire, with the coolest readings along the Midcoast region of Maine.

On Wednesday, the upper level low will begin to shift east. However, there will still be a chance for a shower, mainly over the northern mountains where elevated terrain may assist in the develop of scattered precipitation.

Yet another upper level disturbance will approach New England from the west on Thursday. Most areas will remain dry however as this approaching trough will not be nearly as vigorous as the system early in the week.

AVIATION /04Z SATURDAY THROUGH WEDNESDAY/. Short Term . High cirrus from Fay is starting to spread across the southern portion of the region. Expect rain to develop south to north overnight with IFR conditions likely. Further east the rain will be later to arrive and LIFR fog will impact from RKD to AUG to PWM. Rain showers with IFR will continue through the morning, with breaks in the overcast through early afternoon tomorrow across the south. isolated thunder is possible at all terminals throughout the time period.

Long Term . MVFR/IFR possible in showers and thunderstorms each afternoon through Tuesday, especially away from the coast.

MARINE. Short Term . Strengthening southeasterly flow ahead of Tropical Storm Fay will result in wind gusts to 25kts with building seas, and have issued an SCA through tomorrow night. While the winds will be mainly for overnight the seas will remain up through the day.

Long Term . SCAs will likely need to be continued for seas on Sunday as they will be slow to subside. Otherwise, winds and seas will be below SCA thresholds for much of next week.

HYDROLOGY. The WSR-88D remains in the tropical Z/R relationship.

Tropical Storm Fay will provide a very warm moist environment favorable to heavy rainfall. Expect widespread 1-2 inches in the foothills of the White mountains with localized 3-4 inches amounts possible. These very heavy downpours may lead to localized flash flooding, however existing low river flow levels will mean no threat of widespread river flooding with this system.

GYX WATCHES/WARNINGS/ADVISORIES. ME . Dense Fog Advisory until 9 AM EDT Saturday for MEZ021-022- 024>028. NH . None. MARINE . Small Craft Advisory until 2 AM EDT Sunday for ANZ150>154.
