Area Forecast Discussion National Weather Service Caribou ME 630 AM EDT Wed Apr 21 2021

SYNOPSIS. Low pressure will approach this afternoon. A strong cold front moves through the area on Thursday with an upper level disturbance remaining through the end of the week. High pressure builds into the region Saturday, quickly followed by low pressure passing south of the area late Sunday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. 6:30AM Update: SPC has updated their thunderstorm maps to include Downeast. Updated the weather to show a slight chance of thunderstorms this afternoon. Radar and obs show the rain has started on the south, but the system is quickly moving northward. Updated the current obs for temp and winds. The rest of the forecast looks good.

Previous Discussion . The warm front associated with low pressure centered over Pennsylvania has begun to push into the region, bringing rain into southwestern Maine and Downeast. As the warm front advances NE into the Central Highlands, the warm air advection south of the boundary will follow along. Recent 1000-850mb thickness model runs show the cold air sticking around the St John Valley, North Woods and possibly Central Aroostook for the rest of the day. These temperature differences will be a key factor in the rain/snow line across the region.

By the afternoon, the front will stall over the northern region, causing steady precip for the rest of the day. Recent QPF model runs and WPC guidance show large amounts of moisture linked with this system. With colder temps and higher snow ratio, there’s a possibility for large snow amounts in the North Woods, especially for this time of year. A Winter Weather Advisory has been issued for the North Woods and St John Valley starting this afternoon. Temperatures north of the boundary are expected to be in the upper 30s while below the boundary should range from the low 40s to the low 50s. Areas to the south of the boundary will also see significantly less rain than the rest of the region due to the N movement of the front.

SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/. A significant Spring storm will impact the area with gusty winds, rain, and even snow across northern areas through the period. Pressure falls are noted this morning across Pennsylvania and New York as an upper level trough approaches the area. An embedded shortwave will rotate around the trough later today into tonight, leading to a rapidly deepening area of low pressure that will then move across central New England and into central and southern Maine by tonight. The low has developed slightly southeast of where guidance had it the last couple cycles and an adjustment in low track to the southeast has occurred with the low now expected to track across Downeast Maine and northeast to around Houlton by 6z Thursday. This slight shift to the southeast will enable colder air to remain over a larger swath of the North Woods, leading to a period of moderate to locally heavy snow tonight as a deformation zone forms northwest of the low track. A Winter Weather Advisory has been issued over the North Woods, where significant accumulations are expected near the Quebec border. Snow will accumulate heaviest this evening across the advisory area, but otherwise the event should be spread out over 24 to 48 hours. Both the 12 and 24 hour warning criteria amounts will be approached and are forecast to be exceeded over a small part of zones 1 and 3 near the Quebec border. However, upgrades to warnings may be necessary if a persistent band sets up over a majority of one or more of the aforementioned zones.

Colder air will work eastward during the day Thursday as the surface low pulls northeastward into the Canadian Maritimes, changing precipitation over to snow across much of Aroostook County. Despite the April sun angle and temperatures around or slightly above freezing, snowfall rates will be sufficient for accumulation, especially across northern Aroostook County where a couples inches are expected east of the advisory area. Depending how banding evolves Thursday, the advisory may need to be expanded and/or extended in time to include northeast Aroostook County. The steep pressure gradient from the departing low will also result in strengthening wind gusts. Winds may also approach advisory criteria across the entire area and lead to patchy blowing snow by Thursday night as temperatures drop into the 20s and snow showers/bands persist. Strong winds will also cause damage to trees and possibly power lines where moderate to heavy snow accumulation occurs.

Lingering showers will retreat northward during the day Friday, becoming confined to the Saint John Valley and eventually tapering off by the afternoon. Temperatures will be near to slightly below normal with highs ranging from the mid 40s across the north to mid 50s Downeast. The main story will be winds as the departing low continues to produce a steep pressure gradient with gusts of 35 to 45 mph. Winds will finally diminish Friday evening, though most areas will maintain enough of a breeze to limit decoupling and keep lows from falling below the 30s in all but the most sheltered valleys.

LONG TERM /SATURDAY THROUGH TUESDAY/. High pressure will build in for the day Saturday with partly to mostly sunny skies and temperatures in the 50s and 60s. A coastal low will approach the area Sunday as a southern stream shortwave interacts and tries to phase with the northern stream trough. The antecedent air mass should be warm enough to support a mainly rain event, though a stronger and slightly northwest track associated with earlier phasing of the two aforementioned features could result in some mixing with wet snow across far northwestern areas as shown on the 0z Euro. The low will be slow to depart the area as a negative NAO and upstream blocking develops over Greenland. Lingering showers are possible into Monday evening, but quieter weather should eventually win for Tuesday with slightly warmer temperatures.

AVIATION /12Z WEDNESDAY THROUGH SUNDAY/. NEAR TERM: VFR for early morning with LLWS at all terminals until sunrise. MVFR with possible IFR/LIFR clgs and vsby once the rain/snow begins in the early morning. WSW winds should switch to S winds for southern terminals and NE winds for northern terminals 5-10 kts

SHORT TERM: Tonight-Thu . IFR/LIFR cigs and vsby with snow for N terminals and rain Downeast tonight. LLWS possible tonight. Across northern areas, generally IFR conditions with snow Thursday. Across Downeast areas, generally VFR/MVFR with occasional IFR with any snow showers Thursday. E winds 5-10 kts tonight, becoming WNW 15 to 25 kt with gusts up to 40 kts Thursday.

Thu night-Fri . MVFR cigs across the north with light snow. VFR Downeast terminals. Winds W 10-20kts with gusts up to 40kts.

Fri night-Sat night . VFR. Winds W 10kts becoming light S Sat night.

Sun- Sun night . Becoming MVFR/IFR in the afternoon in rain. Winds S 5-15kts.

MARINE. NEAR TERM: Winds are expected to increase to SCA levels late this afternoon into tonight. Seas generally 1 to 3 ft through this afternoon increasing to 3 to 6 ft late.

SHORT TERM: A Gale Warning is in effect Thu morning, with seas 4-7 ft, increasing to 10-12 feet on the outer waters Thu evening before gradually diminishing Friday morning. Gale force winds are expected on the outer waters Fri morning through the afternoon. SCA conditions will then continue into Sat morning. Seas and winds expected diminish below SCA levels Sat afternoon to Sun morning before SCA and possibly gale conditions return later Sun into Sun night.

CAR WATCHES/WARNINGS/ADVISORIES. ME . Winter Weather Advisory from 2 PM this afternoon to 4 PM EDT Thursday for MEZ003-004. Winter Weather Advisory from 2 PM this afternoon to 4 AM EDT Friday for MEZ001. MARINE . Gale Warning from 8 AM Thursday to 4 PM EDT Friday for ANZ050>052.
