Area Forecast Discussion National Weather Service Boston/Norton MA 956 PM EST Wed Feb 24 2021
SYNOPSIS.
A cold front will bring blustery weather and a return to chillier temperatures Thursday and especially by Thursday night and Friday although with diminishing winds. Periods of unsettled weather this weekend into early next week with a series of fast-moving features passing by southern New England every couple of days into early next week. Mild over the weekend, then colder on Tuesday.
NEAR TERM /UNTIL 6 AM THURSDAY MORNING/.
10 PM Update .
Cold front sliding across eastern New York State. Have not made any significant changes in the latest update other than bringing things in line with the latest observations. Increased sky cover toward the latest HRRRE guidance. Rest of forecast is on track.
7 PM Update .
Cold front moving across central NY led by 1 mb/hr pressure falls across New England and the Hudson Valley. Satellite shows clouds across Western MA and Northwest CT moving east. One patch of showers was crossing North central MA, with others along the front in Central NY. Also, BOX radar shows a 40-50 kt low level jet at 2000-3000 feet AGL supporting wind gusts of 25 kt/30 mph and potentially 30 kt/35 mph at the surface.
Forecast expectations continue, with a period of clouds moving across the region tonight, generating widely scattered showers. Movement of the front extrapolates to the Berkshires around 11PM or midnight, Central Hills around 1 AM, and MA East coast around 2 or 3 AM. Gusty south winds will turn from the west after the front moves through. Temperatures will fall from the upper 30s to mid 40s evening to the upper 20s and 30s by morning.
As everything is roughly on target, no changes are expected.
Previous Discussion .
After the mildest day in some locations in quite a while, temps will not drop that much this evening. A modest southwest LLJ of 55-65 knots will move overhead this evening ahead of an approaching cold front. The result will be gusty southwest winds of 20 to 30 mph developing this evening and perhaps up to 35 mph across the high terrain and portions of the Cape/Islands. This will only allow temps to drop into the upper 30s to middle 40s during the evening hours, although it will feel a bit cooler with the gusty winds developing.
The main impact of the approaching cold front this evening will be an abundance of mid level cloudiness and the gusty SW winds. Low level moisture is lacking, so not much more than a brief sprinkle/spot shower or two expected with the front. Therefore, just included a low pop in the forecast.
Winds will shift to the west behind the front toward morning. Temperatures will have dropped into the 30s by daybreak across most of the region, but still remain above freezing in most locations.
SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/. Thursday .
It will be quite blustery on Thursday with strong cold advection aloft resulting in excellent mixing with NW wind gusts of 25 to 35 mph. However, the cold advection aloft will be offset by a relatively mild start and plenty of late February sunshine. This should push highs into the upper 30s/near 40 across the high terrain and well into the 40s elsewhere. It will feel a bit chillier though given the windy conditions.
Thursday night .
High pressure building in from the west will result in diminishing northwest winds and a return of seasonably chilly temps. Low temps by daybreak will be down into the middle to upper teens across the normally colder outlying locations; to the lower to middle 20s in the urban centers.
LONG TERM /FRIDAY THROUGH WEDNESDAY/. Big Picture .
Dueling jet streams. The southern stream is dominant through Sunday, with one shortwave in particular forecast to move through the flow and up the St Lawrence Valley. The northern stream then takes over across the Northeast USA the first half of next week. A trough from Hudsons Bay moves through the flow and across Eastern Canada, swinging a weak cold front across New England Monday evening and night.
Model mass fields are similar through the weekend, then diverge the first half of next week. As shortwaves are the weathermakers, confidence in timing is less than for a mature weather system. Thermal fields are similar through Sunday. These fields indicate the same trend to colder temps by Tuesday, but show different magnitudes with the GFS the coldest. Overall, moderate confidence through the weekend, trending to low confidence Tuesday-Wednesday.
Details .
Follow the shortwaves during the long term.
One shortwave in the southern stream races up the St Lawrence Valley Saturday, passing to our north and swinging a cold front through during the late day/early night. Temperatures Saturday may initially be cold enough for snow, but likely just a coating, before changing to rain for the midday and afternoon/evening. IVT continues to show a glancing blow by the vapor transport . most passes to our south Saturday 18Z-00Z, but GFS brings 700-800 kg/m-sec to Srn New England while ECMWF barely reaches 700 on the South Coast.
A second shortwave shows in the southern stream on Sunday night, but with disagreement between the models on how much it spreads into Srn New England. GFS says yes, the ECMWF says offshore. Will combine the effects of this shortwave with the third shortwave, which swings a cold front through on Monday. Will feature chance pops for mainly rain showers Sunday night and Monday morning.
A fourth shortwave, also in the northern stream, passes north of New England on Wednesday. Best dynamic lift remains to our north, but close enough to mention low-end chance pops for rain or snow showers.
Mixing temps Friday support sfc highs in the mid 30s to low 40s, then mid 40s to low 50s Saturday and Sunday. Radiational cooling Friday night would suggest upper teens to mid 20s. Dew points in the 30s Sat night and Sunday night suggest min temps no lower than the 30s each night.
AVIATION /03Z THURSDAY THROUGH MONDAY/. Forecaster Confidence Levels.
Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.
Tonight . High Confidence.
Mainly VFR despite an abundance of mid level cloudiness for a time tonight. Perhaps some brief marginal MVFR ceilings impact portions of the interior with the best chance across the high terrain. A few brief spot showers possible through 06z ahead of an approaching cold front. Main impact will be for SW wind gusts of 20 to 30 knots ahead of the front that will shift to the W toward daybreak behind the front. A few hours of LLWS is also expected overnight.
Thursday . High Confidence.
VFR with NW wind gusts between 25 and 30 knots on Thursday.
Thursday night . High Confidence.
VFR with gradually diminishing NW winds Thursday night.
KBOS TAF . High confidence in TAF.
KBDL TAF . High confidence in TAF.
Outlook /Friday through Monday/ .
Friday through Friday Night: VFR. Breezy.
Saturday: Mainly MVFR, with local IFR possible. Windy with local gusts up to 30 kt. RA likely.
Saturday Night: Mainly VFR, with local IFR possible. Windy with gusts up to 30 kt. Chance RA.
Sunday: Mainly VFR, with local MVFR possible.
Sunday Night: Mainly MVFR, with local IFR possible. Chance SHRA.
Monday: Mainly VFR, with local IFR possible. Breezy. Slight chance SHRA, slight chance SHSN.
MARINE. Tonight and Thursday . High Confidence.
A modest southwest LLJ developing ahead of an approaching cold front will bring gusty SW gusts of 25 to 35 knots. Winds will then shift from the WNW with gusts between 30 and 40 knots on Thursday . with the strongest winds across our eastern/northeast outer-waters. the forecast has strong Small craft to Gale Headlines for all waters into Thursday for all waters. Seas over the open waters will build to between 4 and 8 feet.
Thursday night . High Confidence.
NW winds may still gust between 25 and 35 knots early Thu evening, but will diminish to between 20 and 25 knots overnight. This in response to high pressure building in from the west. Seas will also diminish, but may still have some marginal 5 foot seas lingering across the eastern outer most waters through 12z Friday. Outlook /Friday through Monday/ .
Friday: Winds less than 25 kt. Seas locally approaching 5 ft.
Friday Night: Winds less than 25 kt.
Saturday: Moderate risk for Small Craft Advisory winds with areas of gusts up to 30 kt. Local rough seas. Chance of rain.
Saturday Night: Low risk for Small Craft Advisory winds with gusts up to 30 kt. Areas of rough seas. Rain likely.
Sunday: Winds less than 25 kt. Local rough seas. Slight chance of rain showers.
Sunday Night: Winds less than 25 kt. Areas of seas approaching 5 ft. Chance of rain showers.
Monday: Winds less than 25 kt. Local rough seas. Chance of rain showers.
