000 FXUS61 KBOX 150544 AFDBOX Area Forecast Discussion National Weather Service Boston/Norton MA 1244 AM EST Fri Nov 15 2019 .SYNOPSIS... High pressure moving offshore will draw milder air into Southern New England tonight and Friday. Two cold fronts sweep south from Canada Friday afternoon and night. Neither has more than a few clouds with it. But behind the second front will be much colder air and gusty north winds. High pressure will bring a brief period of dry weather Sunday. A coastal storm will then bring rain and wind, possibly some ice Sunday night and Monday. A second storm may impact the region Wednesday and Thursday. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... 1240 AM update... Scattered showers along the boundary lifting NE from the ocean and impacting the outer Cape/Islands. As boundary slides just offshore axis of showers will shift to the east with just a low risk of a shower affecting ACK. Otherwise clearing skies with clouds lingering over the Cape/Islands. Previous discussion... Weak front across far SE MA separating temps around 50 and southerly winds over Cape/Islands from 30s across interior SE MA. This boundary is forecast to shift east overnight with temps falling back into the 30s on the Cape but 40s ACK. Elsewhere, mins will range from mid 20s to lower 30s. Considerable mid/high clouds across the region with lower clouds near the coast. Clearing expected from west to east overnight as mid level drying moves in. However, clouds will linger over Cape/Islands where low level moist axis persists. A few showers have developed over the ocean and are lifting NE. Can't rule out a brief shower overnight over the outer Cape/Islands in the vicinity of the boundary. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SATURDAY/... Model maps show either two cold fronts, or a pre-frontal trough and a cold front, moving across Southern New England. The first trough/front moves through Friday afternoon, the second front moves through early Friday night. Cross sections show limited moisture with dry air at 850 mb and above. PW values less than 0.50 inch. This may be enough for a few clouds but little more. Mixing depths Friday midday will reach between 925 and 950 mb. Temperatures in this layer will support max sfc temps in the upper 40s and lower 50s, cooler in the Worcester Hills and Berkshire East Slopes. This may also tap 20 kt winds at the top of the layer and draw them to the surface in WSW wind gusts. After the second front moves through Friday night, winds will turn out of the north and draw much colder air into our area. The winds will gust 25-30 kt/30-35 mph with strongest winds along the coast. Temperatures upstream over Saskatchewan were in the teens last night, and this looks reasonable for us Friday night. The combination will bring wind chills in the single numbers. && .LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... Highlights... * Temperatures moderate to near seasonal levels but pattern looks unsettled with multiple storm chances. * An ocean storm may impact SNE Sun night into Tue morning with rain and coastal wind along with pockets of ice across the interior. Low confidence on storm impacts and precip types. * Another coastal storm may impact the area Wed into Thu but again low confidence on storm impacts and precip types. Details... Saturday night into Sunday... A cold night with widespread teens in the interior with low to mid 20s for much of Eastern MA and RI except for the immediate coast and Cape Cod, which drops into the upper 20s to mid 30s. Expect clouds to be on the increase Sun morning from the SE. By Sun afternoon, expect NE/ENE winds to pick up especially near the coast as a storm comes up the coast. Sunday high temperatures will likely be warmer than on Sat but still running 5 to 10 degrees below normal (for reference). And despite temperatures in the mid 40s in Eastern MA and RI on Sun afternoon, the winds will make it feel like the low to mid 30s. Further south, an area of low pressure along the Southeast Coast moves northeastwards to the Carolina Coast, which is potentially our next weather maker. More below. Sunday night into Monday... There are still plenty of questions with regards to how fast the aforementioned storm will track up the coast and how close it will approach our area given the large spread of model guidance. One thing to watch is a possible period of ice in interior MA sometime on Monday with warm air aloft a cold air mass if the storm were to come up a little closer. But overall, expect chances of shower to be on the increase late Sunday night into early Monday morning. GFS soundings in Bufkit show a warm nose of +2 to +4C at 850mb in ORH on Monday, with surface temperatures staying at or below freezing the entire day. However, the ECMWF shows the storm staying well south of the 70W/40N benchmark, which would leave most of our area dry with some isolated rain showers towards the Cape. Given the wide spread in models, opted to go with a model blend. The blend shows a chance of freezing rain or sleet west of a Torrington CT-Enfield CT- Worcester MA line on Mon morning changing over to rain showers early Mon afternoon before a possible brief switch back to freezing rain on Mon night and finally ending as rain on Tue morning. East of that line, there could be intermittent rain showers into Tue morning before drying out on Tue afternoon. At this point, it should be emphasized that the confidence in specific locations and duration for possible icing is extremely low. Would definitely have to see more consistency in model runs before having more confidence. But with low-level cold air holding its ground and plenty of mid-level warm air advection associated with low level jet on Monday, the potential for icing does exist, particularly for interior areas. Tuesday... As mentioned above, showers linger on Tue morning, with potential icing in interior MA/CT. As temperatures rise, any icy mix in the interior should transition to rain showers by late morning. Expect precipitation to taper off late afternoon. Tue evening should be dry but with plenty of clouds. Afternoon highs range from low to mid 40s in Western MA/CT to upper 40s to low 50s in Eastern MA and RI. Tuesday night into Wed... The dry period looks to be brief as a storm that develops along the base of a large trough in Eastern U.S. and comes up the coast. Again, there is a wide spread in model guidance. The GFS shows the storm tracking well south of the 70W/40N benchmark and intensifying in Maritime Canada. That would amount to limited impacts for our area. Whereas the ECMWF shows the storm tracking and intensifying over Cape Cod, which would mean widespread rain and high winds Wed into Thu. The biggest snow in this setup would be over interior New England, though areas near the Berkshires could get some snow. Model blend shows widespread chance for rain with snow in Western MA on Wed morning changing over to rain in the afternoon before drying out overnight. Afternoon highs range from upper 30s in Western MA to mid 40s to low 50s elsewhere. Thursday... Thursday looks to be mostly dry with a mix of sun and clouds. Gusty NW winds, however, keep high temperatures in the upper 30s and low 40s in Western MA and mid to upper 40s elsewhere. && .AVIATION /06Z FRIDAY THROUGH TUESDAY/... Forecaster Confidence Levels...

Short Term /through Saturday/...High confidence. Tonight... A few showers early towards the waters along/southeast of the Outer Cape, otherwise largely dry elsewhere. Winds have increased a bit towards the southern coastal/offshore waters, with BUZM3 showing gusts to 25 kts. Marginal/lower-end SCA conditions look on pace with existing SCAs looking valid, with winds 20-25 kts and seas in the 3-5 foot range. Friday... Westerly winds pause in the morning, increase in the afternoon. Seas also subside a little in the morning, then build in the afternoon. Winds gusting near 25 kt, seas near 5 feet on the open waters. Friday night... Cold front moves through early in the night. Winds turn out of the north and increase as much colder air moves over Southern New England and the waters. Winds increasing to near 35 kt during the overnight...seas build to 5 to 9 feet on the exposed waters. We have issued a Gale Watch for this period and continued into Saturday. Outlook /Saturday Night through Tuesday/... Saturday: Low risk for gale force winds with gusts up to 35 kt. Rough seas up to 11 ft.
