SYNOPSIS. Tuesday looks to be pick of the week with many locations breaking 70 along with generally dry weather. A warm front lifts across southern New England early Wednesday and a cold front brings rain, wind, and rumbles of thunder during the afternoon. Thursday is a transition day, before more pleasant weather arrives for Friday and Saturday.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/.

Some scattered showers with an isolated thunderstorm are possible through early this evening. Then as the weak H5 shortwave departs, expect mainly dry conditions overnight as weak ridging builds back into Southern New England. Clearing skies along with light winds should allow for good radiational cooling. Some radiation fog may be possible in the typical fog-prone valley locations. Overnight lows generally in the upper 30s to low 40s.

SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/.

Tuesday .

Tuesday is expected to be the pick of the week as a H5 ridge briefly builds into Southern New England. With 925 mb temperatures between +11 to +13C and good southwest flow (and resultant downsloping), expect highs to be around 70 to 75, except cooler along the immediate south coast and the Cape and Islands. With deep mixing up to 800-850mb, sea breezes should be kept at bay for much of the Eastern MA coast. While most of us will see plenty of sunshine and dry weather, cannot rule out an isolated shower especially north of the Mass Pike as a shortwave trough passes well to our north.

In addition, there could potentially be an elevated risk for fire danger with minimum relative humidity between 25 to 30 percent away from the immediate south coast as well as the Cape and Islands. The recent rain may help to mitigate the risk, however.

Tuesday night .

By Tuesday evening, our attention turns to an amplifying mid level trough and strengthening frontal wave crossing the Great Lakes. Expect clouds to be on the increase, which will help keep temperatures milder, with lows generally in the mid 40s. CAM guidance suggests that most of us should stay dry with better chances for precipitation across our Northwestern zones latter half of the night.

LONG TERM /WEDNESDAY THROUGH MONDAY/.

Highlights .

* Showers & embedded thunderstorms possible Wednesday as a cold front sweeps across the region.

* Cool & raw Thursday with breezy conditions.

* Quiet & comfortable conditions for Friday and Saturday. Unsettled conditions return Sunday.

Wednesday .

Model guidance continues to support a deepening mid-level trough and surface low pressure system moving across the northeast through Wednesday. A warm front noses north during the morning hours which will put much of southern New England into the warm sector of the system - allowing many to climb into the low and middle 60s and dewpoints in the low 50s. Expecting gusty southwesterly winds ahead of the cold front as a 925mb low level jet passes overhead - BUFKIT soundings support deep mixing to over 900mb with lapse rates ranging between 7.0 & 9.0 C/KM during the early afternoon hours. Depending on the timing of the cold front with the movement of the LLJ storms during the afternoon could produce isolated wind gusts to 50mph in embedded showers and t'storms. SPC places southern New England outside of a marginal risk for thunderstorm - something we will keep an eye on moving forward. The cold front will move across the region from west to east during the mid to late afternoon hours with a widespread soaking rain.

Wednesday Night and Thursday .

The cold front passes and we are placed on the backside of the area of low pressure. The center of the low moves northeast towards Nova Scotia and deepens. Southern New England is in the middle of a tight pressure gradient, the low to our northeast and an area of high pressure to our south. Given the strong CAA steepening lapse rates even into the overnight, gusty winds are expected which could be strong enough to consider wind headlines. CAA overnight will drop temperatures into the low 30s across much of southern New England and the upper 20s for the higher terrain of northwestern MA. Northwest flow will continue through the day and will keep temperatures in the 40s to 50 degrees. A few wrap around showers especially across the higher terrain aren't out of the question across western MA/CT.

Friday and Saturday .

High pressure builds in from the south and allows for quiet and dry weather. Temperatures return the the mid and upper 50s for Friday. Saturday we reach well into the 60s.

Sunday .

Models suggest a coastal low pressure system will move off shore impacting southern New England with rain and wind. Still too early to dive into details at this time, but we will continue to monitor.

AVIATION /20Z MONDAY THROUGH SATURDAY/. Forecaster Confidence Levels.

Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.

Through 00z . High Confidence. VFR conditions dominate. Main concern is for a few scattered showers and even an isolated thunderstorm through the early evening hours. Best chance for a thunderstorm is over western MA/northern CT. SW winds 5 to 10 kt, except for localized sea breezes along the eastern MA coast.

Tonight . High Confidence. Any scattered showers should dissipate by mid evening. Otherwise, mainly VFR conditions tonight with perhaps some localized patchy ground fog late in the typically prone locations. Light/Calm winds.

Tuesday . High Confidence. VFR conditions expected. SW winds will gust to around 25 knots during the afternoon.

Tuesday night . High Confidence. Mainly VFR conditions with increasing clouds. Scattered showers possible after midnight for the western terminals. SW winds turning S at 5-10 kt.

KBOS TAF . High confidence in TAF.

KBDL TAF . High confidence in TAF.

Outlook /Wednesday through Saturday/ .

Wednesday: Mainly VFR, with local MVFR possible. Breezy. Chance SHRA, slight chance TSRA.

Wednesday Night: Mainly VFR, with local MVFR possible. Windy with local gusts up to 30 kt. Chance SHRA.

Thursday: VFR. Windy with gusts up to 35 kt.

Thursday Night: VFR. Windy with areas of gusts up to 35 kt.

Friday through Saturday: VFR. Breezy.

MARINE. Tonight . High Confidence. Weak pressure gradient will keep winds and seas below small craft advisory thresholds.

Tuesday . High Confidence. A good setup for gusty nearshore winds during the afternoon. Good surface heating should yield SW wind gusts of 25 kt and choppy seas, particularly near shore. Have opted not to hoist Small Craft Advisories at this point as the 25 kt gusts should be fairly localized and transient.

Tuesday night . High Confidence. Winds diminish well below SCA threshold but seas may approach 5 ft for the southern outer waters.

Outlook /Wednesday through Saturday/ .

Wednesday: Moderate risk for Small Craft Advisory winds with gusts up to 25 kt. Seas up to 5 ft. Slight chance of rain showers, slight chance of thunderstorms, patchy fog.

Wednesday Night: Strong winds with gusts up to 30 kt. Areas of rough seas. Rain showers likely, patchy fog.

Thursday through Thursday Night: Strong winds with gusts up to 30 kt. Rough seas up to 10 ft.

Friday: Moderate risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of rough seas.

Friday Night: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Local rough seas.

Saturday: Winds less than 25 kt. Seas locally approaching 5 ft.
