Area Forecast Discussion National Weather Service Gray ME 935 AM EDT Sun Jun 13 2021
SYNOPSIS. High pressure nearby today wraps up a weekend of fair weather before showers and a few storms return for the start of the workweek, Monday into Tuesday. Clouds and showers exit to the east by Wednesday with fair weather and comfortable temperatures expected through Friday. A warm trend precedes the next chance for precipitation, which will be over the weekend as a frontal system approaches from the west.
NEAR TERM /UNTIL 6 PM THIS EVENING/. Update . Plenty of sunshine will continue to day with mostly high, thin cloudiness crossing the region. Have raised temperatures and dew points for the near term portion of the forecast as readings have already mixed out into the 70s in many areas. Expect a delayed sea breeze today with southerly winds picking up later in the day along the coast.
Prev Disc . 645AM UPDATE . Made minor adjustments to the hourly temperature trends based on early morning observations. Otherwise no changes in forecast thinking for today.
ORIGINAL DISCUSSION . We will squeeze another nice day out of this weekend today as New England finds itself under broadly subsident northwest flow between an upper low over the Gulf of St Lawrence and an upper level ridge over the desert Southwest. Surface high pressure is to our south today with a light west to southwest wind expected. This is bringing in even a bit warmer air than we saw yesterday, with the warmth reaching the coast in southern New Hampshire and southwest Maine. There should still be a sea breeze primarily from Portland eastward, but it will be somewhat later in the day due to the westerly gradient flow. As for cloud cover we'll primarily just be seeing high level cirrus floating by as is already observed on satellite imagery this morning. These clouds will increase late in the day as some showers develop to our west in upstate New York.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/. A shortwave trough dives southeast through the Great Lakes tonight and across New England on Monday. This is a rather robust wave which will eventually carve out a broader trough over the region. For us the impacts from this wave first arrive Sunday night, primarily after midnight, as some showers begin to drift east into New Hampshire. This then spreads east through the day on Monday. Still a good deal of uncertainty from the models on where the more substantial precipitation will fall. In fact, some keep the eastern part of the forecast area dry through the day Monday. Instability is rather weak, so thunder chances will be subdued. With clouds and showers around, temperatures will be a good deal cooler on Monday. A southerly wind will also bring in a cooler influence off the Gulf of Maine.
LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. Deep troughing remains entrenched along the east coast of NOAM through much of the next work week, flanked by strong ridging downstream over the Atlantic Basin and upstream over the Rockies/Plains. While the week starts showery and active, drier air will filter in on the back side of the trough as it drifts east with a seasonable stretch of mostly-fair June weather to round out the workweek. Long range models continue to suggest the pattern turns more progressive over the CONUS by the end of the week, but Atlantic blocking introduces uncertainty for how the trough breaks down . and how much warm ridging we can expect before the next system arrives during the weekend.
Monday night, surface low pressure over Quebec gradually shifts east with a warm front sailing north through New England, driven by a shortwave trough rounding the base of the larger trough. Rain showers accompany the front; have also maintained a slight chance of thunderstorms, assuming it would be left-over daytime convection spilling east into the area late in the evening . with some elevated instability providing support. Overall am looking at a couple to potentially a few tenths of an inch of beneficial rainfalls. Dew points will be on the increase behind the warm front, so temperatures will only cool into the 50s to near 60 with areas of fog in valleys and along the coast in continued onshore flow (at least for east of Portland) Monday night into Tuesday morning.
By Tuesday, low pressure will be centered over eastern Quebec with a cold front/pressure trough extending down the Eastern Seaboard and trailing back over the Deep South. Lapse rates will be steeping aloft which support general thunder chances, but the low- and mid-levels are less certain with a couple waves and corresponding surface fronts at play. WRT the initial front draped down the coast . ahead of the front, dew points remain around 60 degrees which support diurnal destabilization where we can mix, while southerly flow keeps cool/stable conditions over the Mid- coast. Behind the front, dry westerly flow allows for better mixing, downsloping, and more peaks of sunshine with temperatures warming into the 70s and thunder chances owing to steep lapse low/mid-level lapse rates. Two waves aloft provide potential focal points for convection; the preceding shortwave reaching the coast may amplify the extant front during the day, then another wave of Arctic-origin diving south from Canada will push another cold front southeast into New England during the afternoon and evening. While instability may be (relatively) impressive . frontal position and forcing remain in question. In general am expecting the latter front to be the primary focus for scattered convection as it stands the best chance of taking advantage of the diurnal warming trend.
The story for the second half of the week will be Pacific energy plowing into the upstream ridge and progressing the wave pattern downstream . but upstream blocking over the Atlantic only allows for a gradual drift east of the trough over the East Coast. Nonetheless models are in good agreement that a strong dry trend takes hold Tuesday night through Thursday with dew points dropping and skies clearing. Thus in spite of cyclonic flow remaining overhead, have only a slight chance of showers these days, focused over the mountains in NWerly upslope flow. While a cooler airmass drops south into the region with 850 mb temperatures dipping to around +5C . sunshine, downsloping, and mixing will allow temperatures to warm into the 70s, right around average for the year. Late in the week, ridging starts to build behind the trough and push it . or force it to cut off . east of the area. Southwest flow Friday into Saturday lead to a warm trend, culminating in the approach and eventual passage of the next frontal system over the weekend.
AVIATION /14Z SUNDAY THROUGH THURSDAY/. Short Term . VFR expected today with showers gradually spreading in from the west late tonight into Monday. This will bring with it some MVFR or IFR conditions along with a developing onshore flow over Maine.
Long Term . MVFR is expected to prevail Monday night with localized IFR in widespread -SHRA, low ceilings, and patchy fog . the latter two being most likely for coastal and valley terminals. VFR prevails Tuesday through Thursday, except for briefly in -SHRA/potential storms Tuesday.
MARINE. Short Term . High pressure to the south today brings a light southwest flow turning more southerly with time through Monday. Winds may briefly gust to 20 or 25 KT as the pressure gradient tightens on Monday ahead of low pressure.
Long Term . Low pressure approaches the waters Tuesday with showers and possibly storms later in the afternoon, then exits to the east Wednesday with winds backing to the west. Winds and seas may approach SCA thresholds Monday night/early Tuesday but are expected to remain below, and will diminish as broad high pressure builds from the southwest through the second half of the week.
