DAYS 1-5 (JULY 25-29)<\/p>\n\n\n\n
The biggest forecast focus in the short term is today’s heat and thunderstorm threat. The set-up is the classic high pressure offshore \/ cold front approaching and moving in from the northwest. No records are likely to fall in the heat department today but it’ll be pretty hot nonetheless, with high humidity, but not unlimited sun as already high and mid level clouds associated with the upper trough driving the frontal system into our region are already moving in as I write this. So expect some sun limitation from those. What we really need to watch for are developing cumulus \/ cumulonimbus clouds which will be a sign of the thunderstorms. Initially, I think a few isolated storms will pop in southern NH and perhaps north central MA, with eventually these increasing in number while the area moves southeastward, eventually forming a broken to solid line as it moves through the I-95 \/ I-90 belt and southeastward from there. The area with the best chance for the greatest coverage is southeast of the I-95 \/ I-90 region. Regardless, any storm can be strong to severe, so keep a close eye on the sky \/ radar especially if you have outdoor plans. I’m eyeing the possibility of a few more showers and storms, maybe even a small line, that can develop later in the afternoon and impact parts of southeastern NH and northeastern MA, which has been indicated by some reliable short range guidance. By tonight, the front sweeps through and the threat ends. High pressure builds in for Saturday which will be quite a nice day, but you’ll already notice some high clouds streaming across the sky during the day ahead of the next disturbance, which is set to bring more cloudiness back along with the chance for showers and thunderstorms at some point Sunday. Guidance varies on the timing of the shower \/ storm threat from this, but I’m leaning toward a dry morning and afternoon \/ evening unsettled weather. I’ll tweak and detail this on my weekend blog posts. Early next week, fair weather returns along with some July heat to go along with it as there’s no real delivery of Canadian air behind Sunday’s system. Later Tuesday, the next disturbance \/ front may be close enough to trigger late-day showers and storms to the west.<\/p>\n\n\n\n
