Area Forecast Discussion National Weather Service Boston/Norton MA 126 PM EDT Sat Jun 15 2024

SYNOPSIS
High pressure will bring dry and pleasant Father's Day weekend. Dangerous heat and humidity begin to arrive on Tuesday and peak in the Wednesday through Friday time frame. Near record high temperatures are possible with afternoon Heat Indices between 95 and 105 degrees.

NEAR TERM /UNTIL 6 PM THIS EVENING/

A weak shortwave passing overhead is providing just enough lift to increase cloudcover over eastern MA this morning. We should continue to see these dissipate over the next several hours as mid level ridging moves in.

Previous Discussion...

* Plenty of sunshine today with highs well up into the upper 70s to the lower 80s along with lowering humidity

Leftover clouds now confined to eastern MA and expect those to dissipate through the morning as a very dry airmass fills in behind. Winds turn northerly today with highs mainly in the upper 70s to low 80s along with plenty of sunshine. Humidity will also be noticeably lower with dewpoints dropping into the 40s and 50s. Northerly winds and cold air advection will promote mixing which will allow for gusts of 15 to 20 mph today until sunset.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/
Tonight

Upper level ridge axis and surface high pressure move in overhead.
With clear skies, decreasing winds, and dewpoints in the 40s, strong radiational cooling will take place. Overnight lows will drop into the upper 40s to low 50s region wide. NW MA will likely be the coldest with lows in the low 40s.

Tomorrow

High pressure and dry airmass remain over the region. A passing weak 500mb shortwave will bring some high clouds and filtered sunshine to the region. All in all, Sunday will be another gorgeous day with highs in the upper 70s to low 80s, and dewpoints still in the upper 40s to low 50s. Winds will also be also be light as they turn from northerly to southerly late in the day.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/
Key Points...

* Dangerous Heat & Humidity Tue through Fri * Near Record highs with Heat Indices 95-105 degrees * Mainly dry weather next week outside widely scattered t-storm risk

Details...

The main story continues to be the expected dangerous heat and humidity in store for much of the region next week. Ensembles continue to be in excellent agreement in an anomalous upper level ridge building across New England. Guidance shows 500 mb height fields approaching 600 dm in our region...which is rarely seen in our part of the country and a strong signal for the potential of record heat. This is also supported by the NAEFS & EPS Situational Awareness tables...which indicates several parameters outside the models climatology. That is a strong indication for the potential of a rare/highly unusual weather event...in this case being heat and humidity.

The dangerous heat and humidity arrive Tue across the interior, but appears localized sea breezes/onshore flow may limit the initial risk on the immediate coast. The heat & humidity should peak in the Wed through Fri time frame with the only possible relief along the immediate coast during times of localized sea breezes. Otherwise, ensemble guidance data supports near record highs well into the 90s...perhaps touching 100 degrees in spots. If that were to occur...we would challenge all time record highs for the month of June in spots. Either way though the main story will be several days of dangerous heat & humidity. Afternoon Heat Indices will reach into the 95 to 105 degree range. There will not be much relief at night with heat indices remaining in the 70s.

Upper level ridging will keep the vast majority of the upcoming work week dry
That being said
near record high temperatures with modest instability will result in a widely scattered t-storm threat.
This risk may increase towards the end of the work week as a cold front approaches the region.

So in a nutshell...dangerous heat and humidity is the concern for much of next week perhaps even challenging all time June high temperature records in spots!
