DAYS 1-5 (APRIL 15-19)
Three nice days together? Yes. This is going to be true. Today finishes up a holiday weekend for many people, and it’s a traditionally big spring day for our area with Patriots Day activities, the Boston Marathon, and the Red Sox hosting a late morning first pitch. And unless you are a marathon runner who likes it cooler than the 60s, it’s going to be a pretty perfect April day as high pressure builds in with fair, milder weather. Just watch for muddy pathways on unpaved surfaces if you’re trekking about outside, due to abundant rainfall in recent weeks. High pressure holds control through Tuesday, except a cooler center in eastern Canada will start to take over, and this will keep the next round of unsettled weather at bay through most of Wednesday, when we’ll just see an increase in cloudiness ahead of the next system. The wet weather threat from that holds off until Wednesday night or Thursday as a warm front approaches and a wave of low pressure forms on it, but the large scale pattern may hold this system far enough south that we never really even get into any appreciable rainfall from it. And this leads to a Friday forecast uncertainty – does the low, or its remains, drift back to the north as the pattern shifts a bit, or does it just keep on getting pushed away. As of today I’m opting for the former scenario, but this is far from certain, so check future updates.
TODAY: Clouds exit RI & southeastern MA early. Patchy clouds with plenty of sun otherwise. Highs 63-70, warmest interior valleys, and cooler Cape Cod. Wind W 5-15 MPH, higher gusts this afternoon.
TONIGHT: Mostly clear. Lows 45-52. Wind W up to 10 MPH.
TUESDAY: Sunny. Highs 58-65, coolest coast. Wind shifting to N then NE 5-15 MPH.
TUESDAY NIGHT: Clear. Lows 43-50. Wind NE under 10 MPH.
WEDNESDAY: Increasing clouds. Highs 56-63, coolest coast. Wind E 5-15 MPH.
WEDNESDAY NIGHT / THURSDAY: Cloudy. Chance of drizzle favoring eastern coastal areas. Chance of rain favoring southern coastal areas. Temperatures fall to 48-55 then hold nearly steady. Wind E 5-15 MPH.
THURSDAY NIGHT / FRIDAY: Cloudy. Chance of rain showers and drizzle. Lows 48-55. Highs 55-62. Wind E becoming variable 5-15 MPH.
DAYS 6-10 (APRIL 20-24)
Cold front swings through April 20 with rain showers at some point that day. Fair, cool, breezy weather expected as Canadian high pressure slides through the Great Lakes April 21. The April 22-24 period leaves us cool but also vulnerable to low pressure to our south that we’ll have to keep an eye on for potential impact.
DAYS 11-15 (APRIL 25-29)
The pattern heading down April’s home stretch looks cool to start, milder to finish, and trends drier.
