950am EDT Monday Mar 25 2019

Synopsis: A cold front sweeps across the region this morning, followed by cooler but dry weather. Dry weather continues through the end of this week with chilly weather Tuesday gradually moderating as this week progresses. Mild weather next weekend, with a risk of showers increasing Sunday as cold front approaches.

Near Term - Through Tonight
945am update... Cold front is south of the coast and clearing has moved into northern MA. Still plenty of cloud cover south of the Pike and a few sprinkles possible over the Islands this morning. Otherwise, increasing sunshine develops today, although clouds will likely hang tough into the late afternoon over the Islands. Highs 45-50 across much of the region except 30s NW MA. Colder air lagging to the north across northern New Eng will arrive tonight.

Short Term - Tuesday
High pressure moves closer to our region, providing dry weather through Tuesday. Should be very good radiational cooling conditions in place tonight. Favored the lower temperature guidance. Below normal temperatures continue into Tuesday

Long Term - Tuesday Night Through Sunday
Highlights... * Dry weather prevails much of this time period * Gradual warming trend Wednesday & Thu then 60s possible Fri & Sat * Low risk of showers Thu ngt/Friam then again Sat ngt/Sun

Tuesday night and Wednesday... Coldest night of the week as 1034 mb surface high advects into New England. Shallow cold airmass over the area with 925 mb temps down to -6C. This combined with good radiational cooling (mostly clear skies, light winds and a dry/cold airmass) will set the stage for min temps in the teens, low to mid 20s in the urban areas, Cape Cod and Islands. Normal min temp this time of year is in the low 30s, so up to 10 degs colder than normal. Seasonably cool Wednesday with highs in the 40s but with 1032 mb high overhead providing light winds and mostly sunny conditions should take some of the edge off the cool temps. Normal high is 45-50.

Thursday and Friday... Cold front approaches from the northwest so low level warm advection on the increase warming temps into the 50s Thu afternoon. Although increasing SSW winds will yield breezy/windy conditions and cooler temps along the south coast given trajectory across chilly ocean waters (ocean temps upper 30s to lower 40s). Most of the model guidance including ensembles indicate this lead short wave lifts off to the northeast thru southern Quebec, precluding cold front from advancing southward and eventually washing out before reaching southern New England. Thus just a low risk of isolated showers northwest MA with most areas remaining dry. Airmass continues to warm Fri supporting highs possibly into the 60s per ECENS/ECMWF/GEFS and GFS.

Saturday and Sunday... Ensembles and deterministic guidance supporting low pressure developing in the OH valley and advecting an impressive warm sector into New England Sat with highs well into the 60s to possibly near 70! Then uncertainty increases Sat night into Sunday regarding timing and evolution of trough amplification. Thus warm weather could linger into Sunday if trough is more amplified but could also be cooler/showery weather if trough/FROPA is more progressive.

Marine Discussion
Forecaster Confidence Levels... Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.

Short Term - Through Tuesday:
Expecting winds and seas to generally remain less then 25 kt and 5 feet on most of the waters through Tuesday. A few gusts to 25 kt are possible as a cold front moves across the southern coastal waters this morning. Rough seas near 5 feet are possible across the southern outermost coastal waters Tuesday.

Outlook /Tuesday Night through Friday/... Tuesday Night through Wednesday: Winds less than 25 kt. Seas locally approaching 5 ft.
Wednesday Night: Winds less than 25 kt.

Thursday: Winds less than 25 kt. Seas locally approaching 5 ft.
Thursday Night through Friday: Winds less than 25 kt. Seas up to 5 ft
