DAYS 1-5 (MAY 17-21)<\/p>\n\n\n\n
In a “wet” pattern dominated by low pressure, you have your nice times. Yesterday afternoon, for example, was one of those times. While the higher humidity you could feel in the air may have been a little uncomfortable for some, you can’t deny the feel of early summer was with us – sun and clouds, and no showers and thunderstorms to track (they stayed well west and north). Now we reach the weekend and a weather transition will take place as low pressure drifts eastward through the Northeast and southeastern Canada. A large surface low pressure circulation will pass to our north today and tonight, and then shift a bit east southeastward into the Gulf of Maine and the southern portion of Atlantic Canada through Sunday into Monday as well. During this time, upper level low pressure also drifts into and then across the region from west to east – in no really hurry during the trip. The weather outlook in general hasn’t changed since my last update. The aim of this update is to pinpoint the weekend shower threats in more detail. The windows-of-opportunity are somewhat limited, so we’re going to salvage the majority of hours at any given location rain-free versus wet on both days. Today’s best shower threat comes in a west-to-east sweep from late morning to mid afternoon, but any given location would rain for a relatively short period of time. Additionally, another passing shower or thunderstorm can take place from around sunset to late evening, again west to east, and again being of short duration where they would occur. The difference between today and Sunday will be the “feel” of the air. Today’s higher dew points in the warm sector will give the muggy feel, while tomorrow, cooler air and much lower dew points, along with a breeze, will add a bit of chill to the air. As we find ourselves in the northwesterly flow Sunday on the back side of low pressure, any sun that we see will simply help to ignite more clouds, and some of these clouds will produce showers. Our best shot at showers Sunday comes during the second half of the afternoon into the evening. Getting to Monday, the upper low’s impacts are still apparent, with more clouds wheeling around its back side, and still the threat of a few passing showers during the day, although it looks like the greatest threat comes early in the day – will refine that timing. High pressure provides fair weather Tuesday. Enjoy it, because another storm system is on the way, and the rain threat returns during Wednesday. I’ll get more into that threat on tomorrow’s update.<\/p>\n\n\n\n
TODAY: Cloudy through midday with a passing shower possible west to east. Clouds break for sun after with a shower or thunderstorm possible mainly west of I-95 toward evening. Highs 62-69 South Coast, 69-76 elsewhere. Wind S up to 10 MPH becoming variable then SW 5-15 MPH late-day.<\/p>\n\n\n\n

DAYS 6-10 (MAY 22-26)<\/p>\n\n\n\n
Eyeing a coastal storm with wind\/rain into May 22 along with well below normal temperatures. Improvement May 23. Memorial Day Weekend (May 24-26) early outlook: Upper level low pressure can produce diurnal scattered showers Saturday and Sunday before high pressure brings fair weather Monday. Obviously lower confidence that far in advance, but that’s an early call and will be updated and detailed as we get closer to it.<\/p>\n\n\n\n
DAYS 11-15 (MAY 27-31)<\/p>\n\n\n\n
Large scale pattern for the last 5 days of May starts out on the cool side followed by some moderation. We may have to watch yet another storm system just to the south early in the period, but unclear on how big a threat that would be for additional rainfall.
