Quiet weather continues for Tuesday before rain chances return for Wednesday as a cold front comes through. Temperatures on Tuesday start around normal in the mid-40s and will rebound nicely into the low 70s in the afternoon. Winds will be calmer, making that outdoor lunch a little easier, too. Overall, no complaints for Tuesday (weather-wise, anyway).

Weekend forecast: Sunny Saturday, stormy start to Sunday

/ November 25, 2022 at 9:13 PM

We get a good break from the gray skies on Saturday as we find ourselves between storm systems. The lull will bring us a nice, seasonable day, with lows in the mid-40s followed by highs in the mid-to-upper 60s, right in the ballpark for where we should be at this point in the year. The only fly in the ointment will be the risk for minor to moderate salt water flooding around the 9:29am high tide.

Clouds build back up Saturday evening as the next storm system makes its approach to give us another round of rain for Sunday. A warm front will lift north across the area throughout the day, allowing temperatures to top out in the mid-70s despite showers and maybe a thunderstorm or two in the area. The best chance for rain will be in the morning through the early afternoon hours. Expect the front to get through by evening, which will shut off the rain and dry out the air. Winds will be a little breezy with sustained winds approaching 20 MPH with higher gusts.

Sunday will mark the end of this king tide cycle, with minor flooding possible with the 10:28am high tide. A few downpours will be possible with the storm system moving by on Sunday, and we’ll want to watch for any to coincide with the mid-morning high tide.

Improving weather returns to start the new work week; the next shower chance will be mid-week, followed by seasonable temperatures to start December.

Friday & the weekend: A sunshine sandwich

/ November 24, 2022 at 9:54 PM

I hope everyone had a great Thanksgiving Day! The next few days will be a “sunshine sandwich” — overcast and rain, followed by mostly sunny skies, followed by another round of overcast and rain. We will also continue to contend with coastal flooding with the morning high tides through Sunday.

A few showers for Thanksgiving, with more in store this weekend

/ November 23, 2022 at 5:49 PM

We have a relatively mild Thanksgiving Day ahead as temperatures start in the mid-50s, about 10° above normal for this point in the year. Pesky cloud cover will remain pesky with the coastal trough lingering offshore, and a few showers will be possible before rain chances increase further after sunset as more moisture makes its way ashore. Overall, don’t be surprised to dodge a shower or two, but I suspect that a lot of us get a majority of Thanksgiving in rain-free.

Friday & the weekend: Periods of showers with a nice day in the middle

Shower chances will peak on Friday as a warm front moves by followed by a cold front moving in from the north overnight. Lows will approach 15° above normal with cloud cover and a moist airmass in place. The warm front will help temperatures reach the low 70s in the afternoon despite shower activity that’s expected to be in the area. (A thunderstorm can’t be ruled out, either.) These showers will work their way out of here overnight with the aforementioned cold frontal passage.

Saturday should remain mostly dry with a mix of clouds and sun remaining in place. Temperatures will once again bottom out around 10°+ degrees above normal for another mild start followed by highs running right around 70° in the afternoon.

Showers return to the forecast Sunday as another cold front moves by the area. Once again, highs in the low 70s will follow a seasonably mild start to the day in the mid-50s. We should see showers begin to decrease later in the afternoon, paving the way for a cooler, drier, and sunnier Monday.

Coastal flooding remains a concern with morning high tides

This morning’s high tide peaked around 7.02′, which scraped minor coastal flooding thresholds. Expect additional rounds of minor to moderate salt water flooding around times of the morning’s high tide through Thanksgiving and the long weekend. High tide on Thanksgiving morning is forecast to peak around 7.5′, or moderate flood stage, around 7:43am. We should see similar results from Friday morning’s high tide which is predicted to peak around 8:34am. Minor coastal flooding is forecast for Saturday morning’s 9:29am high tide, while guidance indicates another round of flooding will be possible for Sunday morning’s 10:28am high tide. Stay tuned for Coastal Flood Advisories from the National Weather Service.
