DAYS 1-5 (JUNE 12-16)
Quick update for your Sunday. No significant changes to yesterday’s ideas. Today’s not going to be as nice as yesterday, but it does start out very nice. High pressure offshore exerts enough influence to give us sun mixed with the clouds that are advancing ahead of a warm front. That front will eventually thicken up our cloudiness and increase the chance for showers, but while that chance does go up this afternoon, we see most of that activity tonight, along with the potential for embedded thunderstorms as the front crosses and we get into a wedge of warm, humid air. But that will be short-lived as a cold front crosses the region by midday Monday, putting an end to any rain threat. Will this be a beneficial rainfall? Not particularly. While some areas may see a moderate rainfall amount, the short-lived duration and lack of follow-up rain minimizes the benefit. High pressure brings fair weather to the region from late Monday through early Thursday as it slides slowly eastward across the Northeast. Tuesday, we’re on the cool/breezy side of it, Wednesday’s the tranquil day but has the coastal sea breezes, and Thursday we end up in the return-flow on the back side of the high and the region warms up (though not hot). By later Thursday, the next disturbance approaching from the west will at the very least increase our cloudiness, and brings a higher chance of shower and thunderstorm activity as well.
TODAY: Intervals of sun & clouds morning. Clouds dominate afternoon. Scattered light rain mid afternoon on but many areas stay mostly rain-free. Highs 74-81, coolest coast. Wind S-SE up to 10 MPH.
TONIGHT: Mostly cloudy. Showers likely. Chance of thunderstorms. Areas of fog. Lows 61-68. More humid – dew point 60+. Wind S-SW 5-15 MPH.
MONDAY: Variably cloudy with a chance of showers and thunderstorms morning to midday, then sun and passing clouds. Lowering humidity afternoon. Highs 77-84. Wind SW shifting to W 10-20 MPH.
MONDAY NIGHT: Mostly clear. Lows 55-62. Wind NW 5-15 MPH.
TUESDAY: Sun/cloud mix. Highs 71-78. Wind NW-N 5-15 MPH and gusty.
TUESDAY NIGHT: Clear. Lows 51-58. Wind N under 10 MPH.
WEDNESDAY: Sunny. Highs 72-79, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.
WEDNESDAY NIGHT: Partly cloudy. Lows 56-63. Wind variable under 10 MPH.
THURSDAY: Partly sunny. Late day showers and thunderstorms possible. Highs 77-84. Wind SW 5-15 MPH.
DAYS 6-10 (JUNE 17-21)
General northwesterly air flow between a low pressure trough in far eastern Canada and a ridge of high pressure across the central US, with not much movement of large-scale features. Our rain chances will be limited to disturbances traveling along this flow, with the one arriving late Thursday exiting early in this period, and perhaps another around June 20 (though the timing of these is very difficult as their formation is often dependent on thunderstorms far upstream and model guidance struggles to see these well more than a day or two in advance). The take-away, drier than average, no major heat.
DAYS 11-15 (JUNE 22-26)
At this point I don’t see enough evidence to go for a pattern change, so more of the same in the later days of June – but only moderate confidence in this outlook. Overall idea is near to below normal for both temperatures and precipitation.
