Boston dries up as 19-day rain streak nears record before a late-week shift

Boston is approaching a 19-day stretch without measurable rain, a dry run that could shatter recent local records if the weather holds through Wednesday. Meteorologists expect the streak to end when low pressure systems move in on Thursday, bringing a chance of precipitation in the afternoon.

The city has already recorded 15 consecutive days without measurable rain. If Sunday through Wednesday remain dry as forecast, the total will reach 19 days. This marks the longest current dry spell in the region since the streak began earlier this month.

Temperatures are running warmer than typical for early November. Today, Sunday, highs are expected to reach the mid to upper 50s and low 60s, which is close to the seasonal average. The warmth continues into the workweek, with forecasters predicting mid to upper 60s for Monday through Thursday.

Some areas may even hit 70 degrees between Monday and Thursday. This temperature range is about 10 degrees above the average for this time of year, giving the week a September-like feel rather than a standard November climate.

Sky conditions will shift from clear to cloudy as the week progresses. Monday will feature continued sunshine, while high clouds increase heading into Tuesday, which is Election Day. Commuters will likely need a jacket when polls open in the morning but may switch to short sleeves by the afternoon.

Wednesday will bring a mix of sun and clouds. The major change arrives Thursday, which is the next real chance for rain, particularly in the second half of the day. This event would officially close the 19-day dry period.

Late in the week, the weather becomes unsettled. Thursday, Friday, and Saturday all appear likely to see some instability as low pressure gains control of the forecast. While not a total washout, the models show some discrepancy for the latter part of the week, suggesting conditions may vary.
