Area Forecast Discussion National Weather Service Boston/Norton MA 359 AM EDT Tue Jun 18 2024

SYNOPSIS
Dangerous heat and humidity arrive Tuesday away from the south coast and then peaks in the Wednesday through Friday time frame. Near to record breaking high temperatures are possible.
Heat peaks on Thursday before more seasonable temperatures return for the weekend. Showers and thunderstorms possible each afternoon and evening Friday thru Sunday.

NEAR TERM /UNTIL 6 PM THIS EVENING/

345 AM update...

* Dangerous heat and humidity ramps up away from the south coast * Low risk for an isolated t-storm in the interior

Subtropical ridge continues to build across the region today with 500 mb heights rising to 594+ dam. This will be accompanied by a warm sector airmass with lots of sunshine across the area, along with dew pts rising to 65-70 and a anomalous warm airmass, with 925 mb temps of +23C to +25C and +18C at 850 mb. This supports highs of 90-95 across much of northern MA, including the city of Boston and into northern CT and northern RI. These air temps combined with high dew pts will yield heat indices in the mid to upper 90s this afternoon. Hence, day 1 of our expected heat wave this week. Heat advisories remain posted.

Not as hot along the south coast with highs in in the 80s, except mid to upper 70s across the Cape and Islands, with S-SW winds 10-15 mph, gusting up to 20 mph at times, streaming across SSTs only in the 60s. Hence, some relief along the south coast. The east coast of MA may have a brief seabreeze develop from approximately 15z-19z, when winds briefly turn to the SE, but should veer back to the SW after 19z, yielding highs in the upper 80s and lower 90s.

Weak short wave currently across northern NY state is triggering some isolated to scattered showers in that region. Given height rises across SNE today, forcing for ascent will be weak and the atmosphere will likely be capped. Thus, only than an isolated shower/t-storm across western-central MA this afternoon, dry weather prevails elsewhere.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/

345 AM update...

* Not much relief tonight with lows 65-70 * Dangerous heat and humidity continue Wed away from the south coast * Other than a spot shower/T-storm northwest MA, dry weather prevails

Tuesday night...

Mainly clear to partly cloudy conditions along with dry weather prevail beneath building ridge across New England. Lows will be mostly in the mid-upper 60s.

Wednesday...

595 dam ridge remains over SNE, providing mainly dry and hot weather. Airmass warms slightly and combined with mostly sunny conditions, this will support highs in the low to mid 90s from northern portions of CT/RI and into northern MA. These air temps will combine with dew pts of 65-70 to yield heat indices from 95- 100. Some relief south coast and islands, as SSW winds 10-15 mph with gusts up to 20 mph at times, will provide somewhat of refreezing breeze off the cooler ocean with SSTs in the low to mid 60s. As for precip, high amplitude anticyclone over SNE should provide a mid level cap and keep our region mainly dry. Only area for a low risk of an isolated shower/t-storm is across northwest MA



LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/

345 AM update...

* Heat peaks on Thursday with high temperatures in the upper 90s likely for the interior

* Temperatures on Friday remain uncertain with cold front nearby

* Cooler, but still muggy, conditions Saturday and Sunday with chances for afternoon showers and thunderstorms

Very persistent and anomolously strong ridge peaks in intensity on Thursday with 500mb heights making a run at 600mb associated with 850mb temperatures around 20C by afternoon. Given a more NW/W wind component as ridge axis crests, will have some downslope enhancement driving temperatures a few degrees warmer compared to Wednesday. Will note that the overnight guidance trended a bit cooler compared to previous model runs, with highs now projected to remain just below 100F, though still cant rule out a run at the triple digits in the southern CT and Merrimack River Valleys. A Excessive Heat Watch remains in place for Thursday with a determination on an advisory vs warning to be made during later shifts. Shower activity "riding the ridge" looks to remain to our north Thursday afternoon/evening, though it is possible a stray shower develops along the MA/NH border.

Ridge begins to collapse south on Friday as a cold front drops south from NH/ME into our region, increasing shower and t-storm chances during the afternoon. There remains uncertainty in how fast the front will drop south from northern New England, which leads to a wide range in guidance regarding high temps, with an earlier frontal passage yielding cooler daytime highs especially across the eastern half of the CWA For now, elected to follow the NBM for highs on Friday, noting that future updates may need to blend in cooler guidance.

More seasonable airmass remains in place through the weekend though humidity remains high, which will introduce the chance for afternoon and early evening t-storms each day through Sunday. While surface instability wanes with sunset each evening, some storms could continue into the early overnight hours. Cold frontal passage sometime late Sunday-late Monday brings our next chance for more widespread, stratiform precip before another prolonged period of dry conditions.
