KEY MESSAGES

Mainly dry weather continues through most of Sunday, with an increasing risk for showers Sunday night. Near normal temperatures through Sunday night.

Unseasonably warm, June-like conditions are expected next week with highs mainly in the 70s to lower 80s, though confidence is tempered by uncertainty in a potential backdoor cold front. Otherwise, mainly dry with only isolated showers and a period of gusty southwest winds Monday.

SYNOPSIS
Dry weather continues through most of Sunday as high pressure moves across our region tonight, then farther east over the North Atlantic Sunday night. Light winds tonight will mean decent radiational cooling conditions, which is when the ground loses heat quickly on clear nights, and much will depend on how quickly winds diminish.

Much less wind Sunday will lead to near normal high temperatures. For the immediate coastal areas, we will have to contend with seabreezes. Thus, the high temperature for the day could be rather late in the day along the coast, and not really last all that long prior to sunset.

An approaching warm front and a modest midlevel shortwave, which is a small ripple in the upper atmosphere that can cause air to rise, may combine to trigger some showers late Sunday into Sunday night. There is not a tremendous amount of moisture for this system to work with, so we are not expecting more than a few hundredths of an inch of precipitation.

The greatest risk remains north of the Massachusetts Turnpike, and especially towards the northern Massachusetts border into northern New England. This is just due to proximity to the passing mid level shortwave. Any showers are expected to quickly diminish or depart our region late Sunday night.

As advertised, summer-like weather is on the horizon as a strong subtropical ridge builds across the Gulf. This will support southwest flow, moving higher moisture and temperatures into southern New England through the upcoming week. Temperatures are expected to be more indicative of early to mid June rather than early to mid April.

That said, there are potential forecast challenges that could lead to notable misses in temperatures, primarily related to a possible backdoor cold front. There remains considerable uncertainty regarding its timing and placement, which is not uncommon at this lead time.

Confidence should improve as higher-resolution guidance resolves this feature. Ensemble guidance highlights the uncertainty, including DESI (Data Enrichment and Statistics Information) cluster language that shows spreads between the minimum and maximum temperatures on the order of 20 to 25 degrees. This reflects the sensitivity of the backdoor cold front. For now, expect highs generally well in the 70s through the week, with a few days potentially reaching the lower 80s.

The warmest temperatures will likely occur across western portions of southern New England, while the eastern areas have the greatest potential to be impacted by the cooler marine air. Overnight lows will remain mild, generally in the mid 50s to lower 60s.

In terms of sensible weather, no significant large scale storm systems are on the horizon for the coming week. However, with elevated PWATs (Precipitable Water), which is a measure of the total moisture available in the atmosphere, even weak forcing may be enough to generate a few isolated showers or a rumble of thunder at times. No widespread or washout precipitation is anticipated.

On Monday, offshore high pressure and low pressure passing through eastern Canada will tighten the pressure gradient, increasing southwest flow. Expect increasing clouds and moisture. A robust low level jet will be present, with gusts of 20 to 30 knots possible depending on the mixing depth of the boundary layer, which is the part of the atmosphere closest to the ground where we feel the wind. Despite limited precipitation, elevated fire weather concerns may develop Monday afternoon due to gusty winds and dry conditions.

Minimum relative humidity values range from 45 to 60 percent inland and 70 plus percent along the coast. We may need to coordinate with state partners on a possible Special Weather Statement.
