From the National Weather Service office in LOX, issued 5 hrs ago
Synopsis
24/329 AM.
Weak northeast winds are expected to develop this weekend, bringing drier conditions and warmer temperatures to the region that will persist through the first half of next week. Cooler conditions to follow with a growing potential for a significant storm system towards the end of next week.
Long Term (tue-fri)
24/341 AM.
Northwest to northeast winds will increase Monday Night into Tuesday, then weaken into Wednesday. This will keep temperatures largely unchanged with highs in the 70s to lower 80s most common which is right around normal for this time of the year.
The pattern will start to change around Thursday, with onshore flow returning, temperatures dropping, and low pressure forming over the West Coast. This will open the storm window over California, with a growing chance of a significant storm impacting the local area as early as Friday but more so for the weekend. There is a 90+% chance for rain sometime in the Oct 30 through Nov 2 timeframe, likely lasting several hours. Halloween activities are likely to be impacted. There remains a range of outcomes in terms of rain amounts, rates, and winds. At this point, the most likely outcome is for a moderate- level storm in terms of strength and impacts, with a low but present risk for a higher level storm.
