Area Forecast Discussion National Weather Service Boston/Norton MA 335 AM EDT Mon Jun 13 2022 .SYNOPSIS... Showers and embedded thunderstorms with brief torrential rainfall will be coming to an end by mid morning with mainly dry and warm weather this afternoon. Dry weather prevails Tuesday and Wednesday. The threat for showers and thunderstorms will increase Thursday into Friday ahead of another approaching cold front. Drier, less humid and not as warm weather likely returns next weekend. && .NEAR TERM /UNTIL 9 AM THIS MORNING/... * Showers & embedded t-storms with brief torrential rainfall will exit the region by early to mid morning SPC Meso-Analysis currently indicates MUCapes of 500-1000 J/KG with a modest southerly LLJ in association with a mid level shortwave. Pwats were also on the order of 1.5 inches. These parameters combined with the shortwave were resulting in showers and embedded thunderstorms with brief torrential rainfall. Brief/localized hourly rainfall rates in excess of 1 inch were occurring in the strongest storms. This will result in brief poor drainage street flooding, but the activity is elevated and we are not expecting any severe weather. The shortwave will be departing the region early this morning, so most of this activity should exit the region by 7 or 8 am. The exception might be across the eastern MA coast, where some scattered activity persists a bit longer. && .SHORT TERM /9 AM THIS MORNING THROUGH 6 PM TUESDAY/... Highlights... * Mainly dry and warm this afternoon outside a few brief spot showers possible in eastern MA * Sunny and warm again on Tuesday with lower humidity Details... Later this morning and afternoon... The showers and embedded t-storms will be exiting most of the region by early-mid morning. Subsidence behind this shortwave will allow for at least partial sunshine to develop by afternoon. 850T around +13C/+14C should support a warm afternoon with highs topping out mainly in the lower to middle 80s. It will be a bit humid across east and particularly parts of southeast MA/RI as the surface cold front will start to washout near the I-95 corridor. Decent instability will develop in this region with 1000 to 1500 J/KG of Cape and 0 to 6 km shear of 35 to 45 knots. However, subsidence behind the early morning activity coupled with an abundance of mid level dry air will be a significant limiting factor. We might be able to muster a few brief low topped showers along the front in eastern MA, but very dry air in the mid levels will tend to cutoff the updrafts and potential for any significant convection. Tonight... Northwest flow aloft coupled with a ridge of high pressure nearby will result in a dry/pleasant night. We may have to watch for some low clouds and fog patches flirting with the Cape/Nantucket for the first half of the evening, but expect that to dissipate overnight as drier air works into the region. Low temps will mainly be in the 50s to near 60. Tuesday... Dry northwest flow aloft will result in a beautiful Tuesday. 850T near +13C should result in warm high temps mainly in the lower to middle 80s with comfortable humidity levels. Localized sea breezes may develop along portions of the immediate coast keeping temps a few degrees cooler in those spots. Nonetheless...a very nice day is in store for the region. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... * High pressure continues to dominate on Wednesday * Frontal passage may bring showers and thunderstorms late Thursday/early Friday * Unsettled weather pattern this weekend with seasonable temperatures Wednesday Dry/pleasant weather forecast for Wednesday with high pressure dominating the northeast. Onshore flow will keep the coastal areas a bit cooler, but temps are expected to reach the upper 70s/low 80s across the interior. Thursday and Friday High pressure shifts east on Thursday inducing a southerly return flow into southern New England. This will allow temps and dewpoints to climb throughout the day on Thursday. Increasing low-level moisture will result in increasing cloudiness on Thursday as well. Should stay mostly dry, but can't rule out a few warm advection showers across the western areas early in the day. Latest guidances supports additional showers and perhaps a few thunderstorms ahead of a cold front set to push through the region sometime late Thursday or early Friday. Depending on the time of arrival of this front, we may have a synoptic setup supportive for severe thunderstorm development. Wind shear, forcing for ascent , and moisture parameters are expected to be in sufficient ranges to support deep moist convection. With the current TOA for the front to be during the overnight hours, instability may be limited to just a few hundred J/Kg of CAPE. However, should the front arrive later in the day Friday, the atmosphere might have more time to destabilize. Should this occur, greater instability will support an increased risk for severe weather. This will be the time frame to keep an eye on in the extended. Saturday through Monday Cooler drier air filters in behind an exiting cold front late Friday. A deep trough then sets up just off the east coast for the weekend supporting a persistent cyclonic flow. This may result in a somewhat unsettled weather pattern next weekend as a cold pool aloft may support afternoon instability showers. Confidence in any showers/thunderstorm activity next weekend is low, but the cyclonic flow pattern and associated deep northwest flow will likely support seasonable temperatures next weekend and early next week. && .AVIATION /07Z MONDAY THROUGH FRIDAY/... Forecaster Confidence Levels: Low - less than 30 percent. Medium - 30 to 60 percent. High - greater than 60 percent. 6z TAF Update... Today...Moderate Confidence. MVFR-IFR conditions dominate through 12z along with a cluster of showers and embedded t-storms with brief heavy rain. After that time...conditions improve to mainly VFR by early afternoon except perhaps Nantucket and part of the Cape where low clouds and fog may continue to flirt with that region. Mainly dry weather is expected later this morning and afternoon; other than perhaps a brief spot shower or two across eastern MA. S winds of 5 to 10 knots generally switch to a W direction by afternoon. Tonight...High Confidence. VFR other than perhaps Nantucket and parts of Cape Cod; where some low clouds and fog patches may continue to flirt with that region into the evening. Light NW winds. Tuesday...High Confidence in VFR conditions. NW winds of 5 to 10 knots, but localized sea breezes may develop near the immediate coast by afternoon. KBOS Terminal...High Confidence in TAF. KBDL Terminal...High confidence in TAF. Outlook /Tuesday Night through Friday/... Tuesday Night: VFR. Wednesday: Wednesday Night: Slight chance SHRA. Thursday: Breezy. Chance SHRA. Thursday Night: Breezy. SHRA likely, chance TSRA. Friday: Breezy. Chance SHRA, slight chance TSRA. && .MARINE... Forecaster Confidence Levels: Low - less than 30 percent. Medium - 30 to 60 percent. High - greater than 60 percent. Today through Tuesday...High Confidence. A relatively weak pressure gradient will keeps winds/seas below small craft advisory thresholds through Tuesday. Main issue for mariners will be areas of fog across our southern waters into this evening. Outlook /Tuesday Night through Friday/... Tuesday Night through Wednesday Night: Winds less than 25 kt. Thursday: Winds less than 25 kt. Seas locally approaching 5 ft. Chance of rain showers. Thursday Night: Winds less than 25 kt. Seas up to 5 ft. Rain showers likely. Friday: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of rough seas. Chance of rain showers, slight chance of thunderstorms. && .BOX WATCHES/WARNINGS/ADVISORIES... CT...None.
