Given such a strong signal for temperatures to overperform, have
used the 90th percentile of guidance for forecast highs for Tuesday
and Wednesday while the maximum of guidance for Thursday. Should
there be more sun than clouds on Thursday, would not be surprised to
see upper 60s or even a few 70 degree readings especially in the CT
River valley and Merrimack Valley, which tends to see temperatures
overperform due to downsloping. Forecast wise, we have mid to upper
50s on Tuesday, upper 50s to low 60s for Wednesday and low to mid 60
s for Thursday. As with a stout southwest flow, locations away from
the immediate coast will be warmest with coastal locations around 10
degrees cooler due to cold SSTs. Low temperatures overnight Tuesday
into Wednesday as well as overnight Wednesday into Thursday are also
adjusted using the 75th percentile of guidance as warm air advection
continues in earnest. It is not out of the question that we could
see 60s on Friday as well, especially locations in Eastern MA and
RI, especially if the wind shift does not occur till the afternoon
hours and the sun can break out following morning precipitation.
Then it looks like much cooler but seasonable temperatures for the
weekend.
