12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion . UPDATED National Weather Service Gray ME 631 PM EDT Sat Mar 28 2020
SYNOPSIS. High pressure will retreat well offshore tonight. A warm front lifts north overnight, with rain arriving over southern and coastal sections by dawn and a mix of snow and rain across northern New Hampshire and interior western Maine. While a mix of snow, sleet, and some rain continues across the mountains and foothills on Sunday, the remainder of the area will see a cold rain. Colder air will begin to drain back south Sunday night . with precipitation changing to snow and sleet across much of the area with the exception of the southern third of New Hampshire and extreme southwest Maine On Monday. a light mix of rain and snow will continue with any accumulation of snow limited to mountain sections. Cool unsettled weather is then expected for much of the upcoming week.
NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. 630 PM Update . Radar echoes are moving slowly into southern NH and SW Maine early this evening. Dew points are quite low, and not expecting any measurable precipitation for a few more hours. Moisture is slowly increasing however as the column moistens ahead of low pressure moving into NY state and Pennsylvania. Still a few more hours before light precipitation turns into steady rain or snow. Towards daybreak much of NH as well as SW ME will be seeing either snow, rain, or a mix.
Made a few changes, especially for the dew point curve overnight. Temperatures will drop the first half of the night, hold steady then gradually increase in the early morning hours as WAA increases.
Previous discussion . At 18z a 1022 millibar ridge was draped across the area. high was centered over western New England. A warm front extended from the upper Midwest to the DELMARVA. Mid and high clouds continue to spread north and east on GOES imagery and even our far northern sections should cloud over this evening. NWS Doppler Radar mosaic continued to show a large area of precipitation to the north of the warm front over upstate New York. This activity will spread east into southern and western New Hampshire by tonight where it should fall mainly as rain. Some locations mainly from the Lakes Region on north will cool enough with precipitation onset to mix with or change to snow. By dawn . the leading edge of the precipitation will extend from northern New Hampshire through extreme southwest Maine. Both deterministic and ensemble model solutions have trended slower with precipitation onset with the GFS an outlier. Lows will range from around 30 across the mountains with mid and upper 30s for the remainder.
SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/. On Sunday . precipitation will gradually overspread the remainder of the area with a cooling column supporting rain and snow across the mountains and some sleet as a warm layer moves in aloft Elsewhere. we should see largely rain with some pockets of sleet and wet snow possible at times over the foothills Given the expected mix. there will be a wide variation of snow and sleet amounts across the northern mountains. Given later onset time and uncertainty with amounts have held on to the winter storm watch at this juncture. By tomorrow evening . colder air will begin filtering back south and we should see precipitation transition back to snow and sleet across the mountains and foothills with a mix of snow sleet and rain from central New Hampshire through much of interior southwest Maine. Outside of the mountains and foothills I expect little more then a coating by dawn on Monday . with several inches possible across mountain sections. Lows will be near 30 across the mountains with mid 30s elsewhere.
LONG TERM /MONDAY THROUGH SATURDAY/. The warm air advection regime and the first part of the weather system exists on Monday while a strong stacked low moves in to take its place. The mid level low attempts to redevelop just off the coast late Monday and Monday. Enough moisture should be available in conjunction with widespread forcing for ascent to allow for widespread precipitation Monday into Monday night. Normally with upper lows the precipitation tends to be showery, but positive advective processes in association with the redeveloping low will tend toward a more stratiform event. Snow will continue in the mountains with rain (or even a break in the precipitation) elsewhere likely transitioning to snow as Monday afternoon progresses. Low probability for even a 1-4" plowable snow event pretty far south (away from the immediate coast and southernmost NH) ending Monday night.
Otherwise, we'll have to watch for a retrograding low pressure system possibly moving our way for mid to late week.
AVIATION /22Z SATURDAY THROUGH THURSDAY/. Short Term /Through Sunday night/ . Cigs lowering to MVFR then IFR at all but /KAUG/ and /KRKD/ by 12z Sunday in RA and SN . and at /KAUG/ and /KRKD/ by 16z. SFC wind gusting up to 25 kt at coastal terminals Sunday night.
Long Term . Mainly IFR conditions expected in the mountains and foothills Monday and Monday night, transitioning to IFR Monday afternoon and night elsewhere in rain, and then snow.
MARINE. Short Term /Through Sunday Night/ . Increasing onshore flow with building seas Sunday and Sunday night with SCA conditions developing all waters Outside the bays. we cloud see a few gusts approach Gale Sunday night.
Long Term . SCA conditions continue Monday through Tuesday night, mainly for seas 5-10 feet on the outer waters.
GYX WATCHES/WARNINGS/ADVISORIES. ME . Winter Storm Watch from Sunday morning through Monday morning for MEZ007>009. NH . None. MARINE . Small Craft Advisory from 4 PM Sunday to 6 AM EDT Monday for ANZ150>154.
