Area Forecast Discussion National Weather Service Gray ME 932 AM EDT Thu Apr 22 2021

SYNOPSIS. Low pressure will slowly pull away today with gusty west winds, cooler temperatures, and mountain snow showers today in its wake. On Friday high pressure will build south of the region resulting a some moderation in temperatures, however winds will remain gusty. This area of high pressure will result in improved and warmer weather for Saturday before another area of low pressure returns the likelihood of wind and rain over the area on Sunday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. 925am Update . Light snow continues at this hour, mainly over northern portions of the CWA where the winter weather advisory remains in place, and over portions of the capital region. Upstream observations over northern VT and Quebec suggest that the intensity of the snow overall is beginning to wane . but will keep the advisory in place for now. The band over the capital region is also showing signs of decay, but its continued presence necessitated a tweak to PoPs there over the next few hours. Should see a change to rain showers later this morning for areas outside the mountains, but a few flurries may also mix in as well. Finally, adjusted temperatures to match the latest observations. That's all for now.

620 AM Update . Latest radar mosaic shows a band of snow showers moving through the Capital District of Maine and have increased PoPs here and across eastern zones for the next couple of hours. Have also made minor tweaks to near term temperature and sky forecasts.

Previously .

Low pressure over Downeast Maine this morning will deepen this afternoon as it slowly meanders through the Canadian Maritimes. Aloft an upper low at H5 will move overhead late this morning into the afternoon. With the surface low deepening to our northeast the PGF over the area will increase leading to a gusty day with persistent snow showers in the mountains to the International Border into this afternoon.

The latest guidance from mesoscale models has come down slightly with regards to winds today. BUFKIT soundings generally show winds just under 40 kts at H9 with 45 to 50 kts at the top of the boundary layer near 750 mb. With the upper low moving overhead expecting plenty of clouds to minimize the potential for full mixing to these stronger winds at the top of the boundary layer with peak wind gusts today topping out around 40 MPH. There are some signals in the mesoscale models that some fast moving snow or rain showers will track downstream of the mountains late this morning into early afternoon so have gone with 20 percent PoPs all the way to the coast. Further north in the areas in the winter weather advisory, persistent snow showers will accumulate an additional couple of inches into early this afternoon.

Temperatures aloft are cold with H9 temperatures to -5C leading to a cold late April day with highs in the low to mid 40s and well below freezing in the mountains. Highs in the northern valleys will be in the low 30s with snow shower activity waning towards sunset.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/. The gradient over the area will persist through tonight into Friday keeping winds elevated overnight and a resurgence of winds tomorrow with better mixing. Snow showers in the mountains will diminish overnight with skies becoming mostly clear. Lows tonight will be near the freezing mark across southern and coastal areas with mid to low 20s across the north.

Friday will be mostly sunny with continued gusty west winds. As the gradient will be slackening there will be better mixing potential and we will see gusts to 35 MPH during the middle of the day. Temperatures aloft will warm above +5C at H9 leading to highs near 60F across the south and near 50F across the north.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/. High pressure centered to our south will build eastward through the weekend. Our area being on the northern periphery of this high will see a westerly flow with relatively dry weather and warmer temperatures for Saturday. There should be a lot of 60+ degree readings and a fair amount of sunshine. The second half of the weekend is a different story, though.

The next longwave trough comes in two parts. The southern portion tracks across the Midsouth toward the Mid Atlantic while the northern wave moves east out of the Great Lakes. The two will eventually meet up as they reach the East Coast with the southern wave being the more dominant one, strengthening through the merger. Models are in a good degree of agreement on this idea with timing rather consistent as well. Most models bring an area of rain through northern New England beginning Sunday morning and lasting into the evening. CMC was the odd model out with this run as it kept the two distinct waves separate before finally merging near Newfoundland on Tuesday. This scenario left our area as a complete miss when it comes to precipitation on Sunday as the broader trough axis moves through. However, the rest of the model guidance is in pretty good agreement that there will be a substantial rainfall on Sunday with the systems merging in the Gulf of Maine near Nova Scotia. This scenario would still bring the heaviest rainfall further to the east across eastern Maine and the Canadian Maritimes, with generally 0.5 to 1 inch across New Hampshire and western Maine. This is the most likely scenario and the one that this forecast is based upon. I have brought precipitation chances up to 80 percent or higher for much of the area as confidence is high that we will see some rainfall. Again, the timing is pretty well agreed upon, although the ECMWF does linger some wrap around precipitation across western Maine into Monday.

Monday will see a cool northwest flow behind the low with clouds gradually clearing. Cannot rule out some lingering showers especially in the east during the afternoon, but in general it will be seasonably cool and breezy. High pressure builds in for Tuesday with warmer temperatures expected and lighter winds. High pressure maintains its influence over our area through Thursday with gradually warming temperatures. The next trough over the southwestern US will not arrive in our region until late next week or next weekend.

AVIATION /14Z THURSDAY THROUGH MONDAY/. Short Term . Conditions will improve to VFR towards daybreak for all with NW winds turning to the west with gusts to 30 kts. Some upslope snow showers in the mountains may bring periods of MVFR/IFR to KHIE, but confidence is not high enough to put restrictions in the TAF.

Long Term . High pressure passes south of our area on Saturday providing VFR conditions and lighter winds. The next low pressure system brings rain and a return to IFR conditions most of the day Sunday. Improving conditions expected Sunday night and Monday with VFR returning in a northwest flow behind the low.

MARINE. Short Term . Westerly winds will ramp up early this morning with Gale force winds expected into Friday morning. Seas will remain above 5 ft approaching 9 ft later this evening along the outer waters. Winds drop below Gale force Friday with SCA conditions likely into Friday night.

Long Term . West winds continue on Saturday as high pressure passes by to the south. Winds will be lighter, but likely still gusting into the Small Craft Advisory range over the outer waters. The next low pressure system tracks in from the southwest on Sunday and strengthens as it reaches the eastern Gulf of Maine Sunday night. While the exact track of this system is still uncertain, it seems likely that a period of stronger winds will result, with this most likely occurring Sunday night in a northeast flow behind the low. Gale force gusts are possible into Monday.

GYX WATCHES/WARNINGS/ADVISORIES. ME . Winter Weather Advisory until 2 PM EDT this afternoon for MEZ007>009. NH . Winter Weather Advisory until 2 PM EDT this afternoon for NHZ001. MARINE . Gale Warning until 11 AM EDT Friday for ANZ150>154.
