Area Forecast Discussion . UPDATED National Weather Service Gray ME 1110 AM EST Tue Feb 18 2020

SYNOPSIS. A quick hitting low pressure system will bring accumulating snow this afternoon and evening, impacting the evening commute. Snow will transition to a brief mix and then to rain across the southern half of the forecast area before ending tonight. A cold front crosses the area Wednesday bringing snow showers to the mountains followed by breezy northwest winds. Quiet weather will prevail the second half of the week as high pressure settles over the eastern third of the US.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Update . Forcing starting to take shape this morning . with areas of frontogenesis beginning to consolidate into a broader precip shield. Early burst of frontogenesis around H7 led to a narrow band of light snow . with corresponding light accumulation. Plenty of heavy snow reports are beginning to show up across the ALY forecast area . so I fully expect snow intensity to continue to ramp up as the strongest forcing just now moves into SWrn NH. Dry slot is already moving across Wrn NY . so it will be a narrow window for accumulation but snow should be moderate to heavy when it is coming down. The window for most likley heavy snow will be mid to late afternoon . especially over Wrn ME.

Previously . Today, an area of low pressure over Michigan will shift down the St Lawrence Valley, occluding as it does so, driven by a trough digging from central Canada down into the northeast CONUS. Regional radar and satellite shows cooling cloud tops and banded precipitation in isentropic upglide ahead of the low presently over western PA and NY. This broad shield of snow will cross into the Connecticut Valley later this morning and spread northeastward into Maine during the afternoon. As has been observed upstream this morning, the initial band of snow will struggle to reach the surface with very dry mid-levels (<5% on 00Z soundings out of KALB and KGYX). Subsequent bands will be well forced with snow picking up in intensity quickly as the column saturates. As has been well advertised, the time frame for impacts and accumulations will be fairly narrow, about 6-9 hours over any one location, as dry air is quick to intrude behind the occlusion/cold front.

Although precipitation starts initially as snow, surface temperatures gradually rise just above freezing over southern New Hampshire and extreme southwest Maine with a change over to rain before drying out late this evening. As precipitation overspreads the area later in the afternoon, mid-level flow picks up as a SSWerly h850 jet of 50-60kts approaches. While a strong inversion will keep temperatures from warming as strongly at the surface (and thus limit wind gusts inland), a warm nose develops aloft, which leaves the possibility of sleet and freezing rain at the rain/snow transition in time and space south of the Whites. North of a line between Portland and Lebanon NH, temperatures remain mostly below freezing with 2-4 inches of snow by 7 PM, then dry slotting starts to cut in from the west.

After about 7 PM, the forecast grows somewhat more complex as the triple point reaches the coast and amplifies along the southern shore of Maine. Onshore flow brings temperatures above freezing along the MidCoast of Maine with a transition to sleet and rain there. Amplification also enhances forcing over interior western Maine, which will hurl more moisture and force more QPF around the Rt 2 corridor and into the south-facing upslopes of western Maine. Although a wintry mix and rain is forecast over the 95 corridor between Portland and the capital region, higher elevations will pick up another 1-3" out of this. This pushes storm totals into the 3-6" range with locally higher amounts over peaks and ridges.

For headlines . although some locations in the western Maine mountains and the Whites may reach warning level snow (6+"), current thinking is that higher accumulations would be relegated to upslope areas and not necessarily be widespread enough to warrant upgrades. In New Hampshire, a messy period of sleet and freezing rain on top of slushy roadways during the evening commute led to the expansion of the advisory into Merrimack county. Otherwise, advisory-level snow, light icing, and impacts to the evening commute justify winter weather advisories over much of the area.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/. Tonight, dry slotting is quick to filter in behind the occlusion and main shield of precipitation. This cuts PoPs off quickly from west to east late in the evening with most areas dry by midnight. Patchy fog and drizzle may develop for a brief period behind the departing system, then cold advection helps northwest flow pick up and scour out fog up by daybreak Wednesday as temperatures gradually cool into the 20s to near freezing. Troughing continues into Wednesday with breezy northwest winds leading to upslope clouds and a few snow showers over the north.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/. The ensemble and deterministic model solutions are in decent agreement on the long wave pattern through the upcoming weekend into early next week. The forecast period begins with a west coast ridge and a broad trough across much of the remainder of the CONUS. Pacific energy quickly breaks down the ridge and downstream trough with low amplitude split flow for the much of the forecast period By early next week. digging Pacific energy carves out a deep trough over the western CONUS with rising heights downstream across the east. With the exception of a quick shot of arctic air and below normal temperatures to begin the period . we should see above normal temperatures as the arctic air is largely contained to our north and west In the dailies. a few clouds and maybe a flurry for mountain sections Wednesday night with a passing surface trough. Otherwise it'll be cold and dry Thursday and Friday ahead of a building surface high. A milder return flow around the high will allow temperatures to rebound to above average values for the upcoming weekend and the start of the new work week. The next disturbance approaches by Tuesday with thermal profiles hinting at yet another mixed snow and rain event.

AVIATION /16Z TUESDAY THROUGH SATURDAY/. Short Term . Widespread IFR or worse restrictions today as snow breaks out over the region from SW to NE roughly 15-20Z under increasing southeasterly flow. A change over to rain over the coast and southern NH may improve VIS however low ceilings will persist until the system passes and dry air intrudes from the west later this evening. Expect winds to gust 20-25 kts over the coast this afternoon and evening, become variable as the low crosses into the Gulf of Maine, and turn westerly later tonight. Conditions gradually improve to VFR by dawn Wednesday except for at HIE where upslope flow keeps -shsn and MVFR to IFR conditions into the Wednesday. A period of SE to SW LLWS is likely tonight with strong mid-level flow and variable surface winds. Northwest wind gusts 20-30 kts are likely tomorrow with decreasing clouds.

Long Term .

No significant weather related impacts expected.

MARINE. Short Term . Low pressure crossing the region into the Gulf of Maine this evening will lead to a period of gales and 5-10 ft seas. Northwest gusts gradually decline tonight as the system pulls away to the east, but ramp up again on Wednesday, perhaps to gale force once again.

Long Term .

Wed night - Thu . SCA's likely along with freezing spray.

Sat . SCA's possible outside the bays.
