Switching seasons

Yesterday was nice wasn’t it? I imply even if you happen to like the autumn like climate (myself included in that), the random summer season like days with the sunshine are exhausting to complain about. Temperatures yesterday have been extra typical of mid June. By Saturday, the temperatures will likely be extra like mid November. Opening the door for that dramatic drop in temperatures is a chilly entrance that can move by on Friday. Because it does, that storm system will contact of scattered showers by the day. It won’t rain all day. In truth, I believe the rain will are available two separate waves:

First, a interval of on and off showers all morning lengthy. They’ll get began round 6 am and final by midday. From there, we’ll dry out for a couple of hours earlier than spherical two arrives later within the night.

Second, a shorter-lived interval of rain will transfer by within the night. That may very well be heavier rain, however it doesn’t final as lengthy. This second wave is the precise chilly entrance passing by. As soon as that occurs, temperatures will fall shortly into Saturday.

Right here’s a radar snapshot of 7am. You may see the rain simply transferring into the realm:

As soon as that passes we might skinny the clouds a bit, however clouds will dominate by a lot of the day. Temperatures are gentle although, because of a southerly breeze. Highs ought to climb to the mid and higher 60s, which is above the conventional (now 62°).

Friday will likely be breezy by the day, however Saturday appears to be like to take the cake for robust wind gusts. Wind gusts Friday are manageable, topping out 20-30 mph. That’s just like what the wind gusts have been early this morning if you happen to have been outdoors early at present.

The showers will likely be spotty after that second wave Friday night, however they may grasp round for many of Friday night time. The final of the showers might not clear till very early Saturday morning. That is roughly 6-7am Saturday. A lot of the rain is gone, however a lingering bathe may be transferring out of southeastern Massachusetts and the Cape.

As soon as that entrance passes, the wind will shift to the northwest and push in cooler temperatures for Saturday. Saturday is a day the place I wouldn’t give attention to the only temperature quantity (like in your app) for a couple of causes.

First, Saturday will possible be a day with falling temperatures all night time Friday night time and early Saturday morning. So whereas low temperatures for a day are sometimes at dawn, that received’t be the case Saturday. The precise excessive temperature for Saturday may very well be the mid and higher 50s, however that will likely be between midnight and three am, falling from there. So for a lot of the day, temperatures will likely be within the 40s to close 50°. Right here’s a temperature snapshot at 2 pm Saturday.

Second, the gusty wind will make it really feel cooler than this. Saturday noon could have wind gusts 25-35 mph. That can take temperatures within the higher 40s and slash off 5-8° for the seems like temperatures within the afternoon. Right here’s a snapshot of wind gusts Saturday afternoon.

Saturday night, after 6pm the wind gusts will shut down fairly shortly. However with clear skies, a chilly air mass, and a considerably lighter wind, we’ll have a chilly night time Saturday night time/early Sunday morning. A couple of cities have hit freezing this yr — Bedford, the Winery (formally on the airport), and Nashua. Extra of us will hit the freezing mark by Sunday morning.

These are the approximate Sunday morning temperatures:

All of that behind us, Sunday finally ends up being a pleasant day. Chilly? Sure. However not as dangerous as Saturday. Temperatures will likely be somewhat hotter Sunday, however extra importantly the wind will shut off and the skies will keep sunny. That makes these cooler temperatures far more manageable to be out in. So if you’re planning any weekend fall actions, Sunday is your decide.
