DAYS 1-5 (JUNE 25-29)<\/p>\n\n\n\n
It’s “warm front Friday”! While you were (probably) sleeping, clouds came up from the south during the night with areas of showers and drizzle. This will continue through midday today before we start to see some breaks in the clouds from south to north across the region as the front edges northward. This is the surface announcement of the door opening to a classic summer pattern, and rather early in the summer too. A Bermuda High will anchor itself off the US East Coast this weekend into next week and we’ll find ourselves in the classic hot & humid set-up starting Saturday and going at least through the beginning of next week. Initially, when this weekend and early next week were several days away, the medium range guidance was trying to bring a front into the region. This is not going to happen during this period, so the guidance was over-forecasting the ability of that front to get close to and get into the region – a reminder not to put too much stock in model forecast details more than a few days in advance. If we do see any rainfall after today, it would be from air mass pop-up showers and thunderstorms, though the risk of that in any one area during the period from Saturday through Tuesday is fairly low.<\/p>\n\n\n\n
TODAY: Mostly cloudy. Areas of fog and drizzle with scattered showers this morning. Highs 75-82, cooler in some coastal locations. Dew point rising into lower 60s. Wind E up to 10 MPH shifting to S.<\/p>\n\n\n\n
TONIGHT: Partly to mostly cloudy. Areas of fog. Lows 61-68. Dew point lower to middle 60s. Wind S up to 10 MPH.<\/p>\n\n\n\n
SATURDAY: Clouds gradually break for more sun. Areas of fog until mid morning. Highs 83-90, cooler South Coast \/ Cape Cod. Dew point middle 60s. Wind S to SW 5-15 MPH.<\/p>\n\n\n\n
SATURDAY NIGHT: Partly cloudy. Patchy fog interior lower elevations. Lows 65-72, warmest urban areas. Dew point lower to middle 60s. Wind SW up to 10 MPH.<\/p>\n\n\n\n
SUNDAY: Mostly sunny to partly cloudy. Slight chance of isolated afternoon showers or thunderstorms. Highs 85-92, cooler South Coast. Dew point middle 60s. Wind SW 5-15 MPH.<\/p>\n\n\n\n
SUNDAY NIGHT: Partly cloudy. Patches of fog forming interior lower elevations. Lows 65-72. Dew point middle to upper 60s. Wind SW under 10 MPH.<\/p>\n\n\n\n

MONDAY NIGHT: Mostly clear. Patchy fog lower elevations. Lows 66-73. Dew point upper 60s. Wind SW under 10 MPH.<\/p>\n\n\n\n
TUESDAY: Partly cloudy. Isolated afternoon showers and thunderstorms. Highs 88-95, cooler South Coast. Dew point upper 60s to 70. Wind SW 5-15 MPH.<\/p>\n\n\n\n
DAYS 6-10 (JUNE 30\u2013 JULY 4)<\/p>\n\n\n\n
There are conflicts between various medium range models at this time. Example: One model tends to keep a more of the same regime going with a gradual step-down in the heat as a weakening front brings some showers\/storms to the region as it slowly moves through the dissipates. Another model keeps the heat around through July 1 then brings a stronger front through followed by Canadian high pressure with still warm but not nearly as hot and humid weather for the Independence Day Weekend. Given previous “misguided guidance”, we’ll split the difference for now and basically go with the heat hanging around at first, then lessening somewhat, but at least some chance of isolated to scattered showers\/storms into mid period before a weekend drying trend for July 3-4. Tweaks will be needed.<\/p>\n\n\n\n
DAYS 11-15 (JULY 5-9)<\/p>\n\n\n\n
Low confidence forecast. Looking for a weak jet stream to the north and a regional pattern of moderate humidity, warm air, and limited shower and thunderstorm opportunities. <\/p>\n","protected":false},"excerpt":{"rendered":"
