Area Forecast Discussion National Weather Service Gray ME 950 PM EDT Mon Jul 26 2021

SYNOPSIS. A warm and humid air mass will last through Tuesday before a cold front moves through late in the day. This front will be the first in a series that will bring cool and dry air into the region through the end of the week and the weekend. Showers and thunderstorms are possible with the front Tuesday night High pressure will pass through on Wednesday, before another chance of showers late Thursday with another frontal passage. High pressure builds in for Saturday, with another front possible by late Sunday.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. 945 PM Update . Adjusted PoPs some to better align the area of higher PoPs to where showers and thunderstorms are currently located. Although an isolated strong storm will remain a possibility through around 04Z, the threat for severe weather is very low and continuing to diminish as CIN continues to increase over the area. Generally weighted the HRRR pretty heavily for PoPs through the remainder of tonight as it has done a decent job with the ongoing convection. Some minor adjustments to temperatures, winds, and sky cover were also made but overall the ongoing forecast remains on track.

Previously . 7:00 PM Update . Have increased pops across Northern NH and Western Maine as a pre- frontal 500mb shortwave trough begins to approach the region from Quebec province. Convection is beginning to fire across VT ahead of a large cluster of storms in the Saint Lawrence river valley area. WV sat imagery shows the trough that the CAMs are picking up on with the RAP and HRRR keeping activity going until at least midnight across the northern areas. A few strong cells could be possible, and a isolated SVR can't be ruled out at this time, but that is a low prop at this point with a setting sun and decreasing surface instability.

The classic triple H this afternoon: Hazy, hot and humid as smoke from wildfires in Manitoba combines with a warm and sticky airmass. While the Haze is thick enough to reduce visibility to 5 miles and may be keeping us just slightly cooler most of the region is still at or above 80F.

A glace to the Northwest shows what's to come. The thickest portion of the haze ends at the St. Lawrence valley and just behind it convection is beginning to fire ahead of another short wave/cold front just starting to drop into southern Quebec. Timing out this boundary, we've still got most of the afternoon to go in the hot haze before any of the convection can reach the US/Canada border, which should occur around sunset. This morning's sounding out of Maniwaki shows a region of steep lapse rates around 700mb which should help to increase instability. That said, there is also quite a bit of dry air aloft. Overall it's a marginal environment for severe storms, but some gusty winds can't be ruled out in Northwestern Maine late this evening.

Well behind the front we have much drier air moving in but we'll need it to get here first. While the northern parts of NH and western Maine may see that benefit tonight the Maine coast will likely wait out almost until sunrise, and thus continued fog overnight along the midcoast is expected.

SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/. Tuesday a second stronger short wave will push through the region. This will bring scattered showers and thunderstorms to especially the southern Maine and NH south of the White mountains. Forecast soundings suggest some marginal severe storms are possible, with gusty winds being the main threat. Have kept a mention of gusty winds in for the highest PoP.

Overnight behind the front the drier air will come in allowing temperatures to drop. Have leaned on the cooler side of the distribution putting the mountains into the upper 40s.

LONG TERM /WEDNESDAY THROUGH MONDAY/. The long term pattern will continue to be dominated by troughing across eastern North America, with generally below normal temperatures and frequent frontal passages through the next week. The pattern doesn't look particularly rainy, but the chances for showers will increase with the frontal passages roughly every other day.

Breaking it all down, a frontal boundary will be south of the area by Wednesday morning, but lingering showers may still remain across southern New Hampshire. These will diminish by the afternoon hours as high pressure builds into the area. Highs will mainly be in the low to mid 70s.

The influence of the high pressure will be short lived however, as low pressure rides northwest of the area on Thursday. Thursday will start off dry, but a triple point low is likely to develop across the eastern Great Lakes south of the parent low, bringing widespread showers and likely a few thunderstorms into the region later Thursday afternoon through Friday morning. They should move out by Friday mid-morning, but the trough will be deepening on Friday, with cooling temperatures aloft likely leading to some pop up afternoon showers.

The low pressure will strengthen as it moves through the Canadian Maritimes on Friday and Saturday, becoming anomalously strong for this time of the year. This will likely lead to some breezy conditions late Friday afternoon, and then resuming again on Saturday once daytime heating resumes. A weak ridge will build in at the surface for Saturday yielding sunshine, but the upper level trough will reach its maxima on Saturday and Sunday as cool Canadian air pours into the region.

Another front will likely approach the region late Sunday and into Monday, bringing another threat of showers and a fresh shot of cool air for early next week.

AVIATION /02Z TUESDAY THROUGH SATURDAY/. Short Term . MVFR visibilities in Haze will continue through evening before the residual smoke plume moves off shore, thereafter VFR and clear skies will be the rule, although a few scattered showers are possible in the north tonight. Valley fog will drop conditions to LIFR for LEB and HIE, with additional IFR fog along the coast for RKD. tomorrow sunny skies with just a chance for scattered afternoon across southern New Hampshire.


Long Term . Some lingering showers are possible across southern New Hampshire Wednesday morning. A few pop up showers are possible in the afternoon, but otherwise VFR conditions are expected through midday Thursday. A frontal boundary will likely bring widespread showers late Thursday through early Friday. VFR conditions return midday Friday outside of a few afternoon pop up showers and remain through Saturday. Some gusty northwest winds are possible late Friday and again on Saturday. Scattered showers likely return late Sunday.

MARINE. Short Term . Hazy skies will continue across the waters this evening as weak southwesterly flow continues. A cold front will cross the region tomorrow afternoon switching winds to northwesterly.

Long Term . High pressure will build into the area on Wednesday through early Thursday, before an area of low pressure moves in from the west late Thursday through early Friday. A period of SCA conditions with southerly winds are possible Thursday afternoon and night ahead of the system. The low will move into the Canadian Maritimes on Friday and strengthen, possibly bringing SCA conditions with northwesterly winds late Friday through early Saturday. High pressure builds across the waters during the day on Saturday.
