Area Forecast Discussion National Weather Service Gray ME 1022 PM EST Tue Dec 10 2019
SYNOPSIS. A cold front will cross the area overnight with colder and drier air moving into the region. A weak storm system will pass well offshore overnight, and while it will spread snow to the northwest of its track it looks to remain too far southeast. Wednesday will see clearing but cold temperatures, with highs barely reaching freezing. An active weather pattern looks to continue this weekend with low pressure moving up the coast delivering another chance of heavy rainfall.
NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. 1020 PM . Just a few minor tweaks to the forecast based on obs overnight. 00Z NAM12 and latest HRRR support the current forecast with some accums to around an inch in SE NH and along the ME coast S of KPWM, otherwise most places will see a coating at best.
655 PM . Tweaked the forecast a bit for the evening and overnight, but overall thinking remains the same with last surge of precip moving thru ahead of the cold front in the south this evening. Still on track for fast moving wave to move along the front to our south and throw some precip back into srn NH and the ME coast. This will be mainly after midnight and p[probably into the morning commute. Did not change amts, and snow will have a tough time accumulating, given the antecedent warm air and the fact that in some spots, especially on the ME coast it will likely fall at temps abv freezing at the start. Still there some hints that some spots in SE NH and along the immediate Me coast, especially could see a burst of heavier snow just before daybreak, so this may give some spots closer to an inch than dusting.
Previously . Areas of rain showers continue to move N along the approaching front. This will continue likely to categorical PoP for areas S of the mtns thru the evening. MWN is already cooling off with W flow commences . with 30 degrees and freezing rain reported this hour. Gradually cooling of the column will continue . with some flakes possible as precip winds down this evening.
Low level NW flow and drier air will begin to filter into the forecast area tonight. Strong jet aloft and approaching S/WV trof will help to amplify a weak wave along the trailing cold front. This will enhance precip on the cold side of the front. Forecast soundings show a pretty large area of dry air below H7 . despite saturation and lift thru the snow growth zone. Given the expected evaporation and below cloud drift of precip . I have cut snow totals back to generally an inch or less across coastal Wrn ME . and far Srn NH. Some of the higher resolution guidance has even less snowfall than that. That being said the mid level frontogenesis will be strong . I just expect a narrow band that remains to our S.
SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/. Will continue to see clearing into the afternoon Wed. The main story will be much colder temps than today. Highs will top out around freezing . some 20 degrees cooler than highs this afternoon. A reinforcing cold front will arrive late in the day Wed . with snow showers along the front. Some of these could be squally in nature . but overall it should mainly stay upslope snow shower regime. Some light accumulations are possible before approaching ridge brings an end to upslope. Surface axis arrives late . so Wrn zones may see good radiational cooling. I have edged those valleys down a couple degrees from guidance as a result.
LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/. Cold high pressure crests over the region on Thursday as high temperatures remain in the 20s to teens south to north. Thursday night will be the coldest of the week with many spots dropping to the single digits. Trend since yesterday has been slightly warmer on the low temperatures, but have still persisted on the cold side of the guidance, especially for the mountain valleys as the set up looks favorable for radiational cooling.
The next system will move up the east coast Friday night into Saturday morning. Spread on the low location remains quite wide with everywhere from up the St. Lawrence to as far east as the benchmark in play. Ensemble sensitivity shows that much of this variability is due to the placement of the short wave expected to move around the 500mb trough and help to enhance cyclogenesis on Friday. Will likely be another 24 hours or so before we can really start to get some confidence in the surface low track however a warm system, at least aloft, is quite likely and have continued with the rain or snow wording with any frozen precipitation being confined to the north.
Too early still for high confidence in rainfall amounts with this system but certain widespread over an inch with two inches possible. With the track of the low up the east coast it allows significant moisture to flow up from the Gulf of Mexico with PWAT reaching up to 2 standard deviations above normal for this time of year. This combination of rain on the now ripening snowpack will lead to good runoff and the potential for flooding will need to be closely monitored.
Westerly flow takes hold for the second part of the weekend with some upslope showers and clouds likely continuing into the start of next week.
AVIATION /03Z WEDNESDAY THROUGH SUNDAY/. Short Term /Through Wednesday/ . Most of the area has improved to VFR conditions this afternoon . but precip approaching ahead of advancing cold front will continue localized areas of MVFR or lower in SHRA. Cold front moving into the area will help dry out the low levels . lifting CIGs and bringing an end to SHRA. Will likely see a little bit of upslope cloud cover near HIE . so MVFR CIGs may linger there into the overnight. Very bearish about -SN overnight . so have no more than PROB30 for coastal terminals. VFR Wed.
Long Term . High pressure will build in through Thursday with widespread VFR holding through Friday. Another low will track up the eastern seaboard bringing widespread rain to the area Friday into Saturday.
MARINE. Short Term /Through Wednesday/ . Winds have dropped below SCA thresholds at this time . but seas remain hazardous outside the bays. With cold front crossing the waters tonight winds are expected to pick back up with gusts 25 to 30 kts thru morning. I have extended the SCA for all but Casco Bay thru that time. There may be another lull Wed before another cold front crosses the waters with an increase in winds and building seas.
Long Term . High pressure will build over the waters for Thursday. Another low will move up the eastern seaboard with Gales possible in the Gulf of Maine on Friday night into Saturday.
HYDROLOGY. Melt from the past few days of rain has lead to modest rises on area rivers, with NOHRSC estimates indicating up to 2 inches of SWE lost across southern NH. This leaves much of the southern portion of NH snow free. Another system with the potential for 1-2 inches of rain will move through Friday night into Saturday. Most of the rainfall for the Saturday will be runoff across the south with southern NH rivers again seeing the potential for flooding. Further north, into the White Mountains snowpack remains in place and even a rain on snow scenario will likely serve to mostly moisten the snowpack with minimal runoff and less chance for flooding.
