SYNOPSIS

A ridge of high pressure will result in dry weather today through Tuesday with mild days and chilly frost nights, along with elevated fire weather potential. Unsettled, wet and cool on Wednesday.
Drier late in the week and heading into the weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/

330 AM Update...

* Dimming sunshine behind increasing mid level cloudiness today * High temperatures mainly between 55 and 60 this afternoon

A wave of low pressure over the Carolinas early this morning will move east today and stay well south of our region. This will keep our weather dry today...although we do expect an abundance of mid- high level cloudiness to overspread the region later this morning and afternoon. The mid level cloudiness will result in dimming sunshine through the day
That being said
the airmass is quite dry which should allow for afternoon high temperatures to reach mainly between 55 and 60. Westerly winds will gust to 20 to perhaps briefly 25 mph in spots by afternoon with good mixing.

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

Key Points...

* Clearing tonight...lows upper 20s to the middle 30s in many spots * Areas of frost expected to develop very late tonight * Sunny on Monday with highs between 55 and 60

Details...

Tonight...

Low pressure well south of our region tonight will move further east and further away from our area tonight. This will allow the mid-high level cloudiness to move offshore and result in skies becoming mainly clear tonight
There is some westerly flow aloft
but think winds will decouple in many of the low lying spots for a few hours overnight. This coupled with a very dry airmass in place will result in a good night of radiational cooling. Overnight low temps should drop into the upper 20s to the middle 30s across much of the region with the coldest of those readings in the typical low-lying spots of western MA. We did issue a Frost Advisory for CT/RI and southeast MA now that we are into late April.

Monday...

A reinforcing dry cold front will cross the region early Monday morning. This will result in a dry west to northwest flow of air across the region
Model cross sections are quite dry
so expect sunny skies. Although 850T will be between -2C/-3C...we expect a dry super-adiabatic atmosphere on Monday with excellent mixing.
Afternoon high temperatures should recover between 55 and 60 in most locations.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/

Highlights

* Strong radiational cooling Mon Night resulting in widespread frost.

* Mild and breezy on Tue with elevated fire weather concerns possible.

* Gusty winds and showers late Tue Night through Wed. Temps trending cooler.

* Windy, cool and dry on Thu.

* Still dry, but trending warmer on Fri and Sat.

Monday Night...

A ridge axis builds from the TN Valley into the Mid Atlantic/eastern Great Lakes Mon Night. The ridge builds offshore of Mid Atlantic by early Tue. High pressure builds overhead Mon Night, but shifts toward Nova Scotia by early Tue.

Dry and quiet weather expected through this period with high pressure. This brings clear skies and light winds, which will result in strong radiational cooling. The NBM running way too warm for this setup, so went with the 10th percentile of guidance for lows. Should see temps ranging from the mid 20s to the mid 30s. Should see fairly widespread frost. Frost/freeze headlines will likely be needed in future updates.

Tuesday...

Caught under cyclonic flow. A ridge axis will be just off the Mid Atlantic coast early on Tue, while a trough is over the Upper Mississippi River Valley. The ridge gets shunted further to the SE, while the trough digs into the central Great Lakes by late Tue. High pressure nudges in from Nova Scotia, but will build further to the northeast.

Another period of dry and quiet weather, but with gusty winds.
Anticipate there will be elevated fire weather concerns given the well mixed boundary layer per NAM/GFS Bufkit soundings. Shows that we mix up to roughly 800 hPa and we should see some gusts around 20 to perhaps 25 mph at times during the afternoon. In this type of setup guidance tends to under do the temps and we typically end up with drier dew points/RH values. Have a bit more uncertainty on the dew points/RH values as we will be under southerly flow, which tends to keep our moisture up a bit more than say westerly flow. For now went with the 20th percentile of guidance for the min RH, so values range from the mid 20s to the mid 40s. As for temps went with the 75th percentile of guidance, which results in highs ranging from the mid 50s to the mid 60s.

Tuesday Night through Thursday...

Still stuck in cyclonic flow. The trough over the Great Lakes region digs into the eastern Great Lakes by early Wed. A northern stream trough digs from James Bay into Quebec. The trough may interact with the southern stream wave over New England on Wed, though there is uncertainty on how things evolve. The trough cuts off over northern New England late on Wed before lifting toward Newfoundland and Labrador on Thu. A frontal system slides in late Tue through Wed before moving offshore on Thu. Will be stuck between a high over the Great Lakes and a low over the Canadian Maritimes on Thu.

As was the case yesterday the PWAT plume not appearing overly impressive with PWATs below 1 inch per EPS/GEFS and GEPS nil probs of values AOA 1 inch. Deterministic guidance showing we generally we be under roughly 0.75 to 0.85 inches. We do have a deeper SW/W low level jet at 850 hPa, which could help squeeze out the moisture available. At this point deterministic guidance shows roughly 30-40 kt jet in place. Though there is uncertainty on the interaction between the two troughs. If they phase as some guidance indicates this would result in a strong jet, thus a higher wind potential especially as we turn into colder westerly flow. For now have just stuck with the NBM with some minor tweaks for precip timing. Should see roughly a 0.1 to around 0.4 inches of precipitation. Though again a more intense system could squeeze out a bit more moisture and could bring a few thunderstorms for portions of our region Wed.

High temperatures on Wed will be in the 50s. As for Thu we will be cooler in wake of the system with highs in the low to mid 50s. Could be quite windy due to a tightened pressure gradient. May dry out well enough that once again there could be elevated fire weather concerns, but this will hinge on how much precip is realized on Wed.

Friday through Saturday...

Ridge axis builds into the Great Lakes region on Fri and into Sat, but a shortwave may ride the ridge as we head into late Sat. High pressure generally in control through this period, but a frontal boundary may lift toward us late on Sat.

Dry and quiet weather anticipated with temperatures rebounding as we head into the weekend. Do have some uncertainty with the shortwave lifting toward us. Given it is spring time there could be some convective influences. Have just stuck with the NBM for now. Highs around seasonable levels on Fri and slightly warmer than normal on Sat.

AVIATION /08Z SUNDAY THROUGH THURSDAY/

Forecast Confidence Levels:

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

06z TAF Update...

Today...High Confidence.

VFR with just an increase in mid level cloudiness today. W winds 10 to 15 knots with gusts into the lower 20 knots at times this afternoon in some locations.

Tonight and Monday...High Confidence.

VFR conditions continue tonight and Monday. WNW winds generally 5-10 knots. Some risk that a weak sea breeze will develop late Monday afternoon along portions of the eastern MA coast...but that is still uncertain at this time.

KBOS TAF...High Confidence in TAF.

KBDL TAF...High Confidence in TAF.

Outlook /Monday Night through Thursday/...

Monday Night: VFR. Patchy frost.

Tuesday: VFR. Breezy.

Tuesday Night: VFR. Breezy. Chance SHRA.

Wednesday: Mainly VFR, with local IFR possible. Breezy. Chance SHRA.

Wednesday Night: VFR. Breezy. Chance SHRA.

Thursday: VFR. Breezy.

MARINE

Forecaster Confidence Levels:

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

Today through Monday...High Confidence.

A relatively weak pressure gradient will keep winds/seas below small craft advisory thresholds today through Monday. That being said...there is enough heating over the land today to result in westerly near shore wind gusts into the lower 20 knots for a few hours this afternoon.

Outlook /Monday Night through Thursday/...

Monday Night through Tuesday: Winds less than 25 kt.

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

Wednesday through Wednesday Night: Moderate risk for Small Craft Advisory winds with gusts up to 25 kt. Seas up to 5 ft.
Chance of rain showers.

Thursday: Moderate risk for Small Craft Advisory winds with gusts up to 25 kt. Seas up to 5 ft.

FIRE WEATHER

Today and Monday...

There will be elevated fire weather concerns today and again on Monday. Given that we are in a pre-greenup and dry westerly flow will allow for minimum afternoon relative humidity values to drop to between 20 and 30 percent both days with Monday being the slightly drier day. Westerly winds will gust to around 20 to perhaps briefly 25 mph in some spots this afternoon. The winds will be tad lower on Monday, but still expect WNW gusts of up to 20 mph.

BOX WATCHES/WARNINGS/ADVISORIES
CT...Frost Advisory from midnight tonight to 7 AM EDT Monday for CTZ002>004.
MA...Frost Advisory from midnight tonight to 7 AM EDT Monday for MAZ013-016>023.
