DAYS 1-5 (JULY 13-17)<\/p>\n\n\n\n
Your weekend features a split – with warm and muggy weather today, showers and possible thunderstorms until mid afternoon, then drying out. We have to wait for a disturbance to pass through while a quasi-stationary frontal boundary bisects the region. This front will begin an eastward drift, and its northeast-to-southwest orientation means that the bulk of the rainfall coverage from the main event this morning and midday will be generally from the I-95 belt southeastward, though areas west of there are seeing showers initially. The region southeast of I-95 and especially south of I-90 stands the greatest chance of some flooding issues from heavier rain as quite a swath of rain will be moving through between 9 a.m. and 1 p.m. While a drying trend takes place from west to east starting from midday on, one additional bit of instability combined with daytime heating can trigger a couple isolated scattered showers and thunderstorms over interior southern NH and MA later in the day, but odds are most locations will see nothing from this potential. Just keep an eye out if you are out and about. Tonight, drier air arrives. This isn’t genuine Canadian crispness but noticeably lower dew point air that will set up the second half of the “split” I referred to above regarding the weekend weather, and that is a Sunday with plenty of sun and lower humidity, but still quite warm to even hot, but very nice for outdoor summertime activities. Monday through Wednesday, the heat of summer, along with higher humidity, will be back as the Bermuda High re-takes control of the weather. I think the atmosphere will be unstable enough to allow for the potential for at least interior late-day thunderstorms Monday, too stable for anything Tuesday, and then we’ll have to watch for the approach of storms later Wednesday, which is going to be depending on the timing of an a cold front heading this way. This part of the forecast needs to be re-examined and fine-tuned in future updates. <\/p>\n\n\n\n
TODAY: Cloudy until midday with showers and embedded thunderstorms, most numerous and heaviest I-95 southeastward where local flooding is possible.

DAYS 6-10 (JULY 18-22)<\/p>\n\n\n\n
Canadian air – dry, lower humidity, seasonable temperatures July 18-20 (note that July 18 may be a transition day if we have a slower-moving front). Humidity and shower chances increase later in the period as high pressure shifts offshore.<\/p>\n\n\n\n
DAYS 11-15 (JULY 23-27)<\/p>\n\n\n\n
A weak zonal flow pattern keeps a similar pattern going. A shot of humidity with some heat, breaks mid period with another Canadian air mass.<\/p>\n","protected":false},"excerpt":{"rendered":"
