WHAT HAS CHANGED
Upgraded the Wind Advisory to a High Wind Warning for Cape Cod and Nantucket. Expanded the Wind Advisory to include all of Eastern Massachusetts and Rhode Island.
KEY MESSAGES
- Low pressure system brings rain and strong to damaging to portions of southern New England today.
- Cooler than normal temperatures early next week with hit-or- miss shower/thundershower chances during the daytime hours Monday and Tuesday.
- Monitoring possible offshore low development around midweek, which could pass far enough south to allow for warming temperatures, or lead to a continuation of cooler than normal temperatures and possible rains with a closer pass.
DISCUSSION
KEY MESSAGE 1...Low pressure system brings rain and strong to damaging to portions of southern New England today.
The forecast remains on track for a deep trough of anomalously cold air and an associated strong low-pressure system to impact the region today. While this system will bring widespread showers and isolated storms, the primary concern is strong, potentially damaging winds.
Model guidance has remained consistent regarding this wind threat.
As a deepening low rotates offshore, a 45-60 kt LLJ at 925 mb will sweep across eastern portions of southern New England. Model guidance signals distinct pressure rises on the west side of the exiting low. Analyzing from a vertical profile perspective, model soundings show how close the 45 kt+ winds are to the surface. With steep lapse rates, these are good indicators for a good portion of the winds are favored to be mixed down to the surface. A good portion of high-res guidance and the ECMWF and its ensemble show a signal for strong to damaging gusts. The NAM/GFS have leaned on the lower end with gusts. Inland areas can expect widespread gusts 35-45 mph. HRRR means support potential for gusts 45-55 mph near the coast as the LLJ passes overhead. This seems reasonable given that the strongest core of the LLJ passes through east southern New England.
The upper percentiles of the HRRR even suggest a low probability for isolated 60 mph gusts across the Cape and Islands. Winds will ramp up from north to south, increasing after 7 AM for northern locations and peaking for the south coast and Cape and Islands in the afternoon.The current Wind Advisories and High Wind Warnings are currently on track based on latest guidance.
As the system tracks offshore, it will bring another batch of precipitation through the region today. Following a brief lull early this AM, showers will spread southward after 6 AM, likely not reaching the Cape until the early afternoon. Very marginal instability may support a few embedded brief downpours and isolated thunderstorms. Rain will gradually decrease from west to east mid- afternoon into the evening as the low pulls away.
Ensembles indicate rain totals between 0.20" and 1.2" is the more likely range with the higher end totals favored for northeast MA.
In tandem with the strong wind signal, this deep trough is pulling down an anomalously cold airmass that will linger all day, keeping afternoon highs on the chilly side for end of May.
Highs likely stay in the upper 40s and low 50s. Given the timing of the cold air and precipitation, higher resolution guidance, particularly the NAM, suggests some snowflakes mixing in at the higher elevations. It has backed off a little in recent runs, likely due to timing of the steadier precip rates (need that for efficient dynamic cooling). However, it still highlights the north MA border for a trace of light snow. All that said, we could still see a few flakes mix in for the higher elevations of the interior this AM if the timing is right with the higher risk for the high elevations of the northern MA border. No travel impacts expected.
KEY MESSAGE 2...Cooler than normal temperatures early next week with hit-or-miss shower/thundershower chances during the daytime hours Monday and Tuesday.
Ensemble means continue to point to 500 mb troughing governing Southern New England's weather late this weekend into a good portion of next week, in a slow-evolving, blocky 500 mb pattern. There are a couple of upper level lows that will be moving into and/or meandering around Southern New England.
The first of these closed upper lows settles in Sunday night and into Monday, before moving offshore into Tuesday. Really not much change in terms of sensible weather each day, with diurnally-driven, hit-or-mostly-miss showers or low-topped thundershowers popping up with the cool pocket of air aloft associated with the closed low.
This type of showery pattern also means no one area can be guaranteed to be rain-free, but there will be several dry periods in between. Temperatures trend slightly cooler than early-June normals, with values in the mid 60s to mid 70s with comfortable humidity levels. Climatological normals run around the mid/upper 70s for highs.
KEY MESSAGE 3...Monitoring possible offshore low development around midweek, which could pass far enough south to allow for warming temperatures, or lead to a continuation of cooler than normal temperatures and possible rains with a closer pass.
More uncertainty during the mid to latter part of the upcoming workweek with regard to the next surge of vort energy diving southward from the Canadian Maritimes. This feature digs south/south- southwest to a position generally south of 40N/70W into a wound-up, closed mid/upper circulation and associated surface low. The placement of this cyclone, when it begins to exit further offshore and if we see any rainy conditions associated with its north/northeast passage are all unclear at this time. Besides just rain chances, this feature's location will also dictate temperatures as some of the further-offshore/drier solutions bring in shortwave ridging aloft north of it extending into New England, with potential for drier weather and a considerable warmup in temps for at least interior Southern New England. On the other hand, a closer pass to Southern New England would bring cooler than normal temperatures and perhaps some light rains. We offered to not make many changes to NBM at this point and let trends dictate subsequent adjustments to the forecast.
