Area Forecast Discussion National Weather Service Gray ME 403 PM EDT Mon Jul 13 2020

SYNOPSIS. A trough of low pressure crosses New England today and tomorrow with rounds of showers and a few storms, some containing torrential downpours. High pressure builds into the region from Canada on Wednesday. Temperatures and humidity increase toward the end of the week with showers and storms returning.

NEAR TERM /THROUGH TONIGHT/. Today, a 500mb trough extends from eastern Canada down into the Great Lakes region, shifting eastward toward New England tonight. A warm and humid airmass ahead of this wave has produced a favorable environment for showers and storms, mainly focusing on a remnant boundary over southern NH and the coastal plain today. At this hour, the initial round of storms that formed over this boundary are tracking into the waters. More convection is firing over the mountains, and skies are clearing further west in the wake of the departing storms, so expect scattered showers and storms to continue into tonight.

Shower coverage generally decreases overnight with the diurnal trend. Surface low pressure enters the Gulf of Maine tonight and deepens, drawing cooler low-level air in over much of Maine. Scattered rain showers and isolated thunderstorms will tend to focus where low-level convergence is at its maximum over the mountains and into the Connecticut River Valley . with patchy valley fog forming in the high humidity environment. Some subsidence over low-level ridging atop onshore flow may again produce a period of fog over the midcoast over night.

SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/. Tomorrow, low pressure in the Gulf of Maine pulls in cooler air more stable low-level air over Maine in northeast flow. This undercuts instability over those regions for the most part. So, while continued showers are expected to continue as the upper level trough axis crosses, storm activity will wane from north to south through the day. Weak flow and slow storm movement with the humid environment continues at least an isolated flash flooding threat where convection occurs, especially in the CON/MHT/PSM areas where heavy rain has fallen today. Rain showers taper off quickly after sunset as high pressure moves in.

LONG TERM /WEDNESDAY THROUGH MONDAY/. The long term portion of the forecast begins with our area on the western side of a trough axis with a departing upper level low. This low will exit the region early on the day Wednesday and will be quickly followed by rising heights associated with an approaching ridge from the west which will move in late in the day and persist through Thursday. Northeasterly to easterly flow at the surface along with a good deal of cloud cover will only allow high temperatures on Wednesday and Thursday to reach the lower to middle 70s, especially across western Maine.

Starting on Friday the upper level pattern becomes significantly more zonal with our area remaining largely under weak ridging which will allow for an extended period of warm and humid weather. High temperatures on Saturday through Monday will reach the middle to upper 80s across many areas, especially across southern New Hampshire where a few spots may touch 90 degrees. Along the immediate coast and across the beaches temperatures will likely stay into the lower 70s with a cool southerly flow off the ocean.

The greatest chance for rain will occur on Friday and Friday afternoon when a frontal boundary approaches the area from the west. The area of greatest interest as of now looks to be across northern New Hampshire and northwestern Maine where better forcing is expected. Thereafter, typical summer diurnal heating may spark afternoon showers and thunderstorms for Saturday through Monday.

AVIATION /19Z MONDAY THROUGH SATURDAY/. Short Term . VFR prevails for most through the end of the day with localized restrictions in scattered SHRA and a few TSRA. Patchy valley fog and isolated convection may lead to localized restrictions over southern terminals today, otherwise IFR or lower CIGs are possible along the coast with BR/FG over the Midcoast. More MVFR/local IFR restrictions are possible tomorrow with SHRA which tapers off in the evening . TSRA is again possible during this time for southern terminals.

Long Term . VFR conditions expected through early Thursday before MVFR returns for a few hours during the afternoon on Thursday as well as on Friday through Friday night with scattered showers. The best chance for showers will be across northern terminals of northern New Hampshire and northwestern Maine where better forcing is expected. Confidence is moderate for Wednesday through Thursday and low to moderate for the rest of the forecast period.

MARINE. Short Term . Seas approach and linger in the 4-5 ft range over the waters into tomorrow with light winds (except in storms this afternoon) as low pressure crosses into the Gulf of Maine. Seas may reach into the 5-6 ft range later tomorrow as the large wave aloft crosses, but without confidence to issue a SCA at this time.

Long Term . Seas may approach SCA criteria for outer zones on Wednesday morning. SCA may be required for late Friday with winds increasing to between 20-25 kts.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
