Today will feature continued warm temps and moderate humidity as we remain stuck in between a few weather features without any individual entity strong enough or close enough to dominate our weather. As a result, skies are mostly sunny (except for a few clouds/showers drifting through southern NH) and will generally remain that way through the rest of the day. Some clouds will pop up this afternoon in response to some instability generated by our semi-humid airmass and warm temps.
A few of those clouds will become tall enough to produce showers and even a brief thunderstorm this afternoon. Without a strong frontal boundary to focus activity, most towns probably won’t see rain, but the few that do could see quite a bit of it over a relatively short time. One or two of the stronger cells could produce some gusty winds too. Overall, impacts from storms this afternoon are likely to be minimal.
High temps will range from the mid 70s up north to near 90 in southern NH.
I don’t usually do medium-range (3-7 day) forecasts on this blog, but I wanted to drop a quick note here about Tropical Storm Isaias which has formed near Puerto Rico this morning. Most model guidance suggests this storm will become a strong tropical storm or hurricane east of Florida tomorrow or Saturday before turning north in our general direction.
It’s way too early to hone in on exactly what this means for our forecast. We could see the system weaken and be little more than a source of moisture for thunderstorms along an approaching cold front. We could also see it remain strong and produce more significant rain/wind/storm surge impacts. I suspect we’ll have a much better idea by Saturday.
I mention this not because I think Isaias is a serious threat to northern New England, but so that you’re aware that it could be at some point early next week. There’s still too much uncertainty at the moment to warrant immediate action of any kind. That said, if you have a few spare minutes today, I’d suggest thinking about what your plan would be if a strong tropical storm or hurricane were to approach our area. What supplies you’d need, if you would need to evacuate and if so to where, and so on. It’s entirely possible (even likely) that you won’t need to implement that plan next week. But it’s good to have in the back of your head for when a storm does arrive (and one will, eventually whether it’s next week, next month, next year, or next decade).
