12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion National Weather Service Boston/Norton MA 411 PM EDT Sun Aug 9 2020
SYNOPSIS. High pressure settles south of New England, bringing a warming flow of air for the coming week. Should generally be dry, but cannot rule out an isolated shower or storm Monday afternoon. Very warm to hot weather with uncomfortable humidity for much of the upcoming work week. Increasing chances for rain and thunderstorms Wednesday through Thursday, and perhaps Friday.
NEAR TERM /UNTIL 6 AM MONDAY MORNING/.
Highlights
* Any isolated shower/storms end during the evening. Dry and quiet weather expected with stratus and fog along the south coast. Patchy fog may develop across portions of the interior.
A shortwave trough will dig from northern New England/southern Quebec into the Gulf of Maine. Behind the trough, a ridge axis will build into the eastern Great Lakes. At the surface, high pressure will remain offshore to the south.
The position of the surface high will keep low level winds roughly SW to SSW. This will gradually advect upper 60 to low 70 degree dew points into the region with the 70 degree dew points mainly being confined to the south coast.
The increasing moisture coupled with clear skies, light winds and recent rainfall in a few spots may result in some radiation fog across portions of the interior. In addition, will see stratus and fog moving into the south coast. Have once again leaned on the HREF and NAMNest in determining how widespread this activity will be. Mild overnight with low temperatures generally in the upper 60s to low 70s.
SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/.
Highlights
* Heat Advisory for much of southern New England starting Monday afternoon and continuing into Tuesday.
* Isolated showers and storms possible across the interior, but overall expecting most areas to remain dry with sunny skies.
* Dry and quiet Monday night with the stratus and fog returning to the south coast.
Monday .
Ridge axis slides into New England, but may have a very subtle shortwave slide into New York. At the surface high pressure remains offshore, but there may be a weak surface trough over southern New England.
Main concern is the oppressive heat. Low level flow will roughly be WSW to W. Dew points will continue to gradually climb. Generally remaining in the upper 60s to lower 70s. Given the W roughly W winds at 925 hPa expecting some downsloping. Have bumped up the high temperatures to the 90th percentile, which will bring temperatures into the mid 80s to mid 90s across the region. The warmest readings are anticipated across the CT River Valley and Merrimack Valley. The dew points coupled with these temperatures will bring heat index values in the mid to upper 90s. Will see somewhat similar heat index values on Tuesday, so hoisted the Heat Advisory where am most confident in widespread 95+ heat index values.
The forcing is quiet limited across southern New England with the ridge axis building in aloft. Have kept a mention of showers/storms across most of southern New England despite the poor dynamics. Thinking will still see some pop up showers/storms given the surface based CAPE increasing to roughly 1500-2000 J/kg. Will be plenty of moisture in place with upper 60 to low 70 degree dew points. Did lean on the CAMs which does bring slightly higher chances of precip over northern CT into northern RI. Still anticipate most of region to be dry with a few pop up showers/storms. Mid level lapse rates and deep layer shear are very poor, so do not expect any severe storms.
Monday night .
Any showers/storm come to an end during the evening due to the loss of heating. High pressure remains offshore. This will bring dry and quiet weather with stratus and fog returning to the south coast.
Will feel quite muggy across the region with dew points remaining in the upper 60s to low 70s. Winds at 925 hPa will be roughly WSW to W and this will advect 22 to 24 degree Celsius air in. This will keep lows right around those dew points with readings in the upper 60s to low 70s.
LONG TERM /TUESDAY THROUGH SUNDAY/.
Highlights .
* Very warm to hot weather with uncomfortable humidity levels for much of this work week. Potential heat wave in some locations.
* Wet/unsettled Wed and Thu as a stalling cold front offers opportunities for showers/thunderstorms. Signals for possibly locally heavy rain, though details on when and where are still uncertain.
Details .
Above normal temperatures likely to persist into Wednesday, although Wednesday should be a little cooler than Tuesday due to more clouds. Heat Advisory likely needed for some locations Tuesday, and perhaps Wednesday. Most likely areas will be the CT River Valley and Metrowest into the Merrimack Valley.
A cold front is still expected to linger around southern New England during the mid week time frame. Once this front moves past our region, expecting temperatures to be near to slightly below normal into next weekend. Surface dew points are also expected to drop slightly behind this front.
This slowing cold front will provide a focus for showers and thunderstorms Wednesday into Thursday. With the tropical humidity levels, a few downpours will be possible. Not looking at a widespread rainfall during this time, although most of the region will be at risk for these showers and thunderstorms.
More mixed signals towards the end of next week. Some of the guidance, namely the NationalBlend, GFS and CMC, are much more aggressive generating rainfall north of a cold front. Finding this concept difficult to accept. Just about all guidance have a strong high pressure over Quebec during this time. Pattern recognition suggests this cold front will be well south of our region Friday into next weekend, meaning dry weather is more likely across southern New England. This is in line with the latest ECMWF and WPC solutions.
AVIATION /19Z SUNDAY THROUGH FRIDAY/.
Forecaster Confidence Levels .
Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.
Through 00Z . High confidence
Generally VFR conditions anticipated. There is potential for the return of IFR stratus at ACK towards 00Z, but confidence is low on the specific timing. Could see an isolated shower or thunderstorm move through until 22-00Z. Best chances are at BAF to ORH/BED. Not out of the question PVD sees something pop up in next hour or two, but think the sea breeze should hold any activity off as it lifts northward. Winds SW around 5-10 kts. Could be around 10-15 kts along coastal areas due to the sea breeze including BOS.
Tonight . High confidence
VFR with light SW winds. Stratus and fog developing along the south coast. Could see anywhere from MVFR to LIFR conditions due to the stratus. Also, may see some patchy fog across the interior. Think majority of areas will be fog free, but there is a better shot where any showers/storms move through.
Monday . High confidence
VFR with light SW to W winds. Any stratus/fog lifts during the morning. Isolated shower/storm possible across the interior. Could see some gusts pick up across the south coast to 15-20 kts during the afternoon.
Monday Night . High confidence
VFR with light SW winds. Stratus and fog developing across the south coast.
KBOS Terminal . High confidence in TAF
KBDL Terminal . High confidence in TAF
Outlook /Tuesday through Friday/ .
Tuesday: VFR.
Tuesday Night: VFR. Slight chance SHRA.
Wednesday through Wednesday Night: VFR. Chance SHRA, isolated TSRA.
Thursday: Mainly VFR, with local MVFR possible. Chance SHRA, isolated TSRA.
Thursday Night: VFR. Chance SHRA, isolated TSRA.
Friday: Chance SHRA, isolated TSRA.
MARINE.
High pressure remains offshore. Expecting generally quiet weather, but fog and low clouds are possible tonight and Monday night. This fog/stratus should remain across the southern waters and southeast of Cape Cod. Should see visibility reductions in the 1 to 3 nm range.
Should see this stratus/fog burn off Monday morning and again Tuesday morning. Waves at or below 4 feet. Winds out of the S/SSW at 10-15 kts with gusts around 15-20 kts.
Outlook /Tuesday through Friday/ .
Tuesday: Winds less than 25 kt.
Tuesday Night: Winds less than 25 kt. Seas locally approaching 5 ft.
Wednesday: Winds less than 25 kt. Slight chance of rain showers.
Wednesday Night: Winds less than 25 kt. Chance of rain showers.
Thursday through Friday: Winds less than 25 kt. Chance of rain showers, isolated thunderstorms.
