Thursday: One more quiet, dry day before unsettled weather returns
Thursday should be generally quiet across the metro area for the vast majority of the day as dry air characterized by dewpoints in the mid-60s — about as good as it gets at this point in the year — hang around for one more day. Expect the day to start in the low 70s once again with highs warming to the upper 80s in the afternoon. Clouds will be on the increase throughout the day as a disturbance approaches, with a slight chance of showers after sunset, but again, the vast majority if not all of us get Thursday in rain-free.
Friday & the weekend: Unsettled weather resumes as moisture returns
Moisture makes a comeback overnight Thursday into Friday, and this combined with a front drifting south into the area and continued disturbances riding through within northwest flow will send rain chances up markedly to close the work week. The vast majority of us should measure rain at some point on Friday, and some of it may be quite heavy at times. Temperatures will be suppressed by the widespread rain, and we should only see highs top out in the mid-80s on Friday.
Saturday will continue to feature scattered coverage of showers and thunderstorms throughout the day as the aforementioned front hangs around. We should see enough breaks in the storms to allow temperatures to return to the low 90s in the afternoon, however. Heavy rain remains a concern but severe weather doesn’t look like a major issue at this point.
Storm coverage backs down a little more for Sunday, but there will still be potential for a decent scattering of storms particularly in the afternoon and evening hours as highs top out in the low 90s once again.
Coastal flooding concerns continue through Friday
Coastal flooding will continue to be a concern Thursday and Friday nights. Expect minor to moderate flooding with the 10:31 PM high tide Thursday and minor flooding with the 11:23 PM high tide Friday. Another couple rounds of Coastal Flood Advisories look likely, though impacts will get progressively later in the evening as the tides peak later. After Friday, we should be far enough from the astronomical effects of the full moon, and surface winds should also swing back around to an offshore trajectory.
