DAYS 1-5 (JULY 31 – AUGUST 4)
It may be mid summer still, but this final day of July has started out almost with a hint of fall in the air with a nice cool air mass in place and a gusty breeze picking up again. The breeze will settle back down and the temperature will climb enough to remind you it’s still summertime, though it will be a cooler-than-normal day, but nice and dry for enjoying outdoors. A wind shift to south brings in more humidity and eventually we see more clouds on Sunday as two systems approach the region, a trough to the west and low pressure to the south. It looks like our greatest chance of rainfall comes Sunday night, but will be limited as we are basically between the two disturbances. The southern low brings the best chance of rainfall to the South Coast region while the western trough brings a shower threat to areas mostly north and west of I-95 Sunday night, but that trough line will swing through the region Monday and still may produce a brief shower or thunderstorm as it passes by. Otherwise Monday’s trend will be for slightly drier but seasonably warm air. High pressure is going to become more established off the US East Coast in the early days of August and by Tuesday and Wednesday we’ll find ourselves in a south southwesterly air flow of warmth and somewhat higher humidity, but likely absent of any rainfall.
TODAY: Mostly sunny to partly cloudy. Highs 72-79. Dew point middle to upper 40s. Wind W 5-15 MPH.
TONIGHT: Clear except fog patches forming over interior lower elevations. Lows 52-57. Dew point upper 40s to lower 50s. Wind SW under 10 MPH.
SUNDAY: Mostly sunny morning. Partly sunny afternoon. Highs 75-82. Dew point rising toward 60. Wind S 5-15 MPH.
SUNDAY NIGHT: Mostly cloudy. Chance of showers and possible thunderstorms. Areas of fog. Lows 61-68. Dew point lower to middle 60s. Wind SW 5-15 MPH.
MONDAY: Partly sunny. Chance of a brief passing shower or thunderstorm. Highs 77-84. Dew point near 60. Wind W up to 10 MPH.
MONDAY NIGHT: Mostly clear. Lows 61-68. Dew point near 60. Wind variable under 10 MPH.
TUESDAY: Mostly sunny. Highs 77-84, coolest coast. Dew point near 60. Wind variable up to 10 MPH with light coastal sea breezes.
TUESDAY NIGHT: Partly cloudy. Fog patches forming. Lows 62-69. Dew point lower 60s. Wind S up to 10 MPH.
WEDNESDAY: Partly sunny. Highs 76-83, coolest South Coast. Dew point middle 60s. Wind S 5-15 MPH.
DAYS 6-10 (AUGUST 5-9)
A southerly air flow and increased tropical moisture brings a better chance of shower activity during the August 5-6 period before high pressure strengthens and keeps us warm and fairly humid but with mostly rain-free weather for the August 7-8 weekend and on through period’s end.
DAYS 11-15 (AUGUST 10-14)
Transition back toward more westerly flow into the middle of August probably means another round of unsettled weather somewhere during this period, favoring early to mid period. No major temperature departures from normal are indicated at this time.
