DAYS 1-5 (APRIL 26-30)<\/p>\n\n\n\n
Upper level low pressure will continue its influence on our weather for 2 more days. We start today with marine layer stratus in place across most of the WHW forecast area – though with some holes in the cloud cover especially in the western reaches of the region around the Connecticut Valley. I do expect this cloud cover to erode further as the sun climbs into the sky, for at least a partly sunny resolution, if not mostly sunny for a while, but the same sun that gave the heating to break up the stratus will provide heat that ignites cumulus clouds development, and with another disturbance approaching as it rotates around the upper low, this can help give rise to a few showers in the region later. I do think today’s shower activity will turn out a little less potent and with less coverage than yesterday’s did. With some easterly component to the wind this afternoon and especially through Thursday, the tendency for marine layer stratus to move onshore will be there, extending inland at times as well. I do think the shower threat will be lower on Thursday, though, but there can be a patch of drizzle here and there with more moisture from the ocean in the lowest levels of the atmosphere. Finally, as the upper low pulls away and a weak area of high pressure moves in, we should see more substantial clearing for Friday, although sun’s heating will likely still help to pop some diurnal cumulus clouds, preventing 100% sun. Still, Friday seems to be the pick of the week. And then the weekend dilemma: Guidance in the medium range has been kind of on the same page about unsettled weather returning, but then during yesterday’s runs became more in agreement about a pair of low pressure areas impacting the region as we head through the last couple days of April (and May 1), with the first of them arriving on Saturday (April 29). At that point we will have a ridge of high pressure having been over the region on Friday, and still some blocking in the atmosphere. Sometimes the guidance does not resolve this blocking strongly enough, and even though we do have some agreement in the guidance, as of this update I am going to bank on the aforementioned error being part of a model tendency to bring the initial low in too quickly, so I am going to forecast dry daylight hours Saturday, with increasing clouds as the initial low starts to weaken while running into high pressure, with some of its lingering rain reaching the region during Saturday night, and the second low actually being faster and becoming the one main system, bringing wet weather into the region during Sunday. This is not a super-high confidence forecast, obviously, but my initial guess for the end of the 5-day, and subject to adjustment over the next few updates. Just plan on an unsettled weekend, but one that may start out “ok”.<\/p>\n\n\n\n

DAYS 6-10 (MAY 1-5)<\/p>\n\n\n\n
Going against model trends of two separate low pressure areas, with the second one impacting the region on May 1, for a forecast that shows improvement that day as a singular storm system from the day before departs, but upper level low pressure is again set to linger in the region for a good portion if not throughout this period with near to below normal temperatures and occasional shower chances.<\/p>\n\n\n\n
DAYS 11-15 (MAY 6-10)<\/p>\n\n\n\n
General idea remains that the Northeast will see a trough of low pressure in place with a trend for it to slide eastward with time, keeping it cooler than normal overall and with limited and decreasing shower chances over time.<\/p>\n","protected":false},"excerpt":{"rendered":"
