Area Forecast Discussion National Weather Service Gray ME 955 PM EDT Sat Jul 4 2020

SYNOPSIS. A cold front will cross the area Sunday bringing a chance for showers along with afternoon and evening thunderstorms. A few thunderstorms could produce strong gusty winds and hail. Heat and humidity will build as we head through next week, along with a chance of afternoon and evening showers and thunderstorms most days.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. 955 PM Update . Low clouds and fog continue to progress inland late this Saturday evening. Otherwise, any showers have dissipated. The fog could be locally dense overnight but so far visibilities have remained at or above 1 mile at most locations.

635 PM Update . Have updated the forecast mainly for minor adjustments to sky and wx grids as low clouds and fog continue to roll inland with the loss of daytime heating. A few areas of dense fog are likely but confidence on widespread 1/4 mile or less not high enough at this point for a dense fog advisory. Will continue to monitor. Otherwise, isolated convective showers in the mountains and foothills will dissipate shortly.

Previously .

A few stray convection cells popping up just E of Somerset county,so will have to watch those and the possibility of a couple more developing a little further west thru late afternoon. Other than that watching fog offshore, and in some cases currently onshore, start to creep back inland, and this trend will likely continue through the evening with fog and stratus returning along the coast for much of tonight. Should see the stratus move inland into the coastal plain as well this evening. I think the mtns will stay mainly clear, although valley fog is likely to develop as well, but Tds also dropping, so that will help limit any of the stratus from making too far into the foothills. Lows range the mid-upper 50s in the mtns to the low 60s along the coast and in srn NH.

SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/. Once again on sunday will be dealing with light flow and fog/stratus that will be slow to dissipate, so any sun on the coastal plain will likely not be seen until closer to midday. The weak flow that starts the day should switch onshore quickly, but also with approaching short wave, may see enuf of PG to help the S-SE flow move further inland. NH will be warmer than warmer ME because of this with highs in the low to mid 80s, while highs in ME will be around 80 inland, and in the 70s near the coast.

500 mb wave will begin to track SE out Quebec and into nrn New England during the afternoon, which will be enuf to se off some convection. Timing is such that this looks like a late afternoon early evening event, with probably a line of convection developing and moving SE across the CWA. Could some stronger convection develop along the main boundary and the more unstable just to the west of it, mainly in central and srn NH and interior SW ME. Thinking strong winds will be the biggest, but these will also be more good lightning producers.

Storm should diminish by late evening with some slightly cooler and drier air behind it, but timing is such that the air mass may not mix down until Monday morning, and we could be stuck with another round of fog Sun into early Mon. Lows will be in the 40s again to around 60 in srn Nh and along the coast.

LONG TERM /MONDAY THROUGH SATURDAY/. The ensemble and deterministic model solutions are in good agreement on the long wave pattern through next week and into the upcoming weekend. We begin the period with rising heights as an upper low exits into the maritimes. The resulting pattern will feature low amplitude flow and a mean jet position to our north . allowing the heat and humidity to build with little in the way of relief this period. In the dailies . an area of high pressure builds east into the region for Monday with comfortable temperatures and humidity levels to round out the holiday weekend. By Tuesday the high has shifted offshore . with the return southerly flow ushering progressively warmer and more humid air into the region. On both Wednesday and Thursday . passing shortwave impulses and associated weak surface reflections should trigger fresh rounds of showers and thunderstorms. Ridging should bring a quieter day on Friday with only widely scattered convection possible across inland sections. The next shortwave impulse and weak surface reflection should bring a round of more widespread convection to the area by late Saturday.

AVIATION /02Z SUNDAY THROUGH THURSDAY/. Short Term . Fog/stratus to move back again early this evening along the coast with vly fog at KLEB/KHIE. The fog/stratus will be slow diminish Sun morning, with brief improvement to VFR Sunday, before a line of SHRA/TSRA move through late aft and early eve.

Long Term .

Wed - Thu . Sct MVFR with brief lcl IFR in afternoon and evening SHRA/TSRA.

MARINE. Short Term . Winds seas stay below SCA criteria. Persistent fog bank remain in place through Sunday, and may clear Sunday night.

Long Term .

Wed . Winds could approach SCA outside the bays.

TIDES/COASTAL FLOODING. High astronomical tides could bring some splash over and beach erosion around the time of high tide late this evening. However . we should see less of an impact than last night.

GYX WATCHES/WARNINGS/ADVISORIES. ME . Beach Hazards Statement through Sunday evening for MEZ023>028. NH . Beach Hazards Statement through Sunday evening for NHZ014. MARINE . None.
