1207am EDT Wednesday May 18 2022

Low pressure will continue to track north of the region tonight, then exit across the northern Maritimes Wednesday. High pressure will build across the region Wednesday night into Friday. An upper level disturbance will cross the region later Thursday. High pressure crosses the region Friday. A cold front will approach later Saturday then cross the region Sunday.

Near Term - Through Today
1207AM Update: Satellite images show the mid level cloud deck still lingering over the north, helping to cap temps in the 40s so far. Some sprinkles across the north will continue tonight. No major updates to the forecast except for current obs.

Prev discussion blo... The vertically stacked low just west of the state in Quebec will continue to be the primary weather maker into Wednesday morning. The low will fill and meander towards the Gaspe Peninsula by Wednesday while a shortwave upper ridge propagates towards Maine. Moisture wrapping cyclonically into the forecast area will continue to generate showers this afternoon and evening, but most activity will be hung up towards the western international border through tonight. Cold air advection will affect the entire area with H850 temps dropping towards minus 5C by early Wednesday in northern and western zones. These colder temps may actually result in snow for terrain above 1500 to 2000 feet tonight, but a warm boundary layer will ensure no snow falls in any populated area. Probability of Precipitation for tonight will be mostly in the northern zones with Quantitative Precipitation Forecast of just a few hundredths. The cold advection will result in lows tonight in the 30s north and lower 40s south. The strong pressure gradient behind the low will keep the boundary layer mixed all night and gusts to 25 mph may occur at times. The winds will pick up quickly again Wednesday morning with widespread gusts to 30 mph into the early afternoon. With the cooler temps aloft in place, even a deep mixed layer in the afternoon won't push highs beyond the mid 50s in Aroostook County. The coast will again benefit from the offshore winds, allowing highs to reach the low to mid 60s. Clouds in the morning will move east and dissipate by midday as very dry air moves into the area, in spite of the northwest flow. The dew points may drop towards the teens and low 20s for the afternoon and won't support any cumulus. Have gone below most guidance for the afternoon dew points.

Short Term - Tonight Through Friday
High pressure crosses the region Wednesday night with mostly clear/partly cloudy skies. High pressure exits to the east early Thursday, with a fast moving upper level disturbance starting to cross the region late. Expect increasing clouds Thursday, with increasing shower chances during the afternoon. Showers will persist early Thursday night with the upper disturbance. The disturbance then exits across the Maritimes overnight, with surface high pressure starting to re-build late. Showers will end overnight in the wake of the disturbance leaving partly/mostly cloudy skies. High pressure crosses the region Friday, then begins to exit across the Maritimes late. Expect partly sunny skies Friday. Temperatures will be at slightly below normal levels Thursday. Above normal level temperatures are expected Friday.

Long Term - Friday Night Through Tuesday
A cold front will approach the Saint Lawrence River Valley Friday night. Expect an area of showers, remnants of earlier convection to the west, to cross the region Friday night. The cold front will slowly cross the region through the weekend, though the exact timing remains uncertain. Expect a chance of showers, along with afternoon/evening thunderstorms, in advance of the front through the weekend. The cold front will exit later Sunday night with showers/thunderstorms generally ending in the wake of the front. However, could still have the slight chance of a shower early Monday. High pressure should build across the region Monday through Tuesday with partly cloudy/mostly clear skies. Above normal level temperatures are expected Saturday/Sunday. Near normal level temperatures are expected Monday/Tuesday.

Near Term: Will maintain the Small Craft Advisory as advertised into midday Wednesday. While the intracoastals fall below criteria tonight, expect strong wind gusts nearshore Wednesday morning and opted to err on the side of caution by leaving the intracoastals in the advisory from now through midday. In terms of seas, the steep five-footers this afternoon will slowly diminish tonight into Wednesday.

Short Term: Winds/seas below small craft advisory levels Wednesday night through Friday. Showers Thursday afternoon into Thursday night.
