Great Stretch of Weather!

Fri 7/11: Best stretch of weather so far this summer? Perhaps. We are smack in the middle of a 3 to 4 day stretch of mostly sunny and warm weather that will last through Sunday, with very low chances of rain, and clouds for that matter. Though the humidity will gradually creep back up over the course of the weekend, it should still be a nice summery Saturday and Sunday around Cape Cod.

Friday is about as good as it gets. A refreshing breeze, nearly 100 percent of the possible sunshine, low humidity and temperatures in the mid to upper 70s. It almost feels a bit like September, the month in which, by my opinion, Cape Cod enjoys its best weather of the year. If you can, get out and experience it as these kind of days are rare in July.

The high pressure cell bringing Friday's great weather will remain in control - and continue to bring fair weather - both Saturday and Sunday. However, with the surface high slipping offshore, a return flow of southerly wind will help boost the humidity over the course of the weekend, with dew points in the mid 60s on Saturday and in the upper 60s on Sunday. Saturday looks to be the nicest of the two days as Sunday will feature more humidity, a bit more haze, an active southerly wind and possibly some patches of fog early and late in the day along some south facing beaches. Though, overall, both days will be good with highs near 80F and virtually no threat for rain.

After a dry weekend, the chances of wet weather will increase as we head into the Sunday night through Tuesday period. A cold front will inch slowly into New England during this time frame, firing off lines of showers and thunderstorms. The slow movement of the front, combined with a well established southerly flow of warm and humid air means a good chance of showers at some point in that window - with the highest likelihood currently being Monday or Monday Night. We will also have to watch any area of low pressure that tries to form off the Carolinas, as it could bring a round of more organized wet weather - though computer guidance is becoming less enthusiastic about this idea with time.

As for Bertha, she will remain well away from the East Coast of the United States. She will meander near the island of Bermuda for the next few days, before gradually turning to the northeast and accelerating out into the central and north Atlantic as she is finally picked up by an advancing trough. The only impact we have to watch for, barring some major and highly unlikely shift in forecast track, is the potential for increased ocean swell later this weekend into the first part of next week. South and east facing beaches would be most prone. Larger swells can increase the chances for Rip Currents.
