1 Key Message 1
Mainly dry weather continues through most of Sunday, with an increasing risk for showers Sunday night. Near normal temperatures through Sunday night.
2 Key Message 2
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.
KEY MESSAGE 1... Mainly dry weather continues through most of Sunday, with an increasing risk for showers Sunday night. Near normal temperatures through Sunday night.
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, much will depend on how quickly winds diminish. Much less wind Sunday will lead to near normal high temperatures. For the immediate coastal areas, 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 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 not expecting more than a few hundredths of rainfall. The greatest risk remains north of the Mass Pike, and especially towards the northern MA border into northern New England. This is just due to proximity to the passing mid level shortwave. Any showers are expected to quickly diminish/depart or region late Sunday night.
KEY MESSAGE 2... 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.
As advertised, summer-like weather is on the horizon as a strong subtropical ridge builds across the Gulf. This will support southwest flow, advecting 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 busts 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, with spreads between the minimum and maximum temperatures on the order of 20-25 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 impacts 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 synoptic systems are on the horizon for the coming week. However, with elevated PWATs, even weak forcing may be enough to generate a few isolated showers or a rumble of thunder at times. No widespread or washout rainfall 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 20-30 knots possible depending on the mixing depth of the boundary layer. Despite limited rainfall, elevated fire weather concerns may develop Monday afternoon due to gusty winds and dry antecedent conditions. Minimum RH values range from 45-60 percent inland and 70+ percent along the coast. May need to coordinate with state partners on a possible Special Weather Statement.
