Weather to Watch
Weather to Watch: November 7, 2026
Five weather lessons for November 7: South Texas rain, Hawaii trade wind showers, Washington coastal winds and surf, South Dakota fog, and slow Caribbean showers.
Watch how terrain, fronts and local winds change where rain falls, how far fog spreads and when seas build. Here are five places to follow on Saturday, November 7.
1. South Texas: Why the heaviest rain may shift
When to watch: Saturday afternoon, November 7, through Monday morning, November 9 (CST).
Easterly winds rising over the Sierra Madre Oriental can help start showers near the Rio Grande and Edwards Plateau on Saturday. Early Sunday, a band of faster winds just above the ground and an approaching front add lift over the Brush Country. With deep moisture in place, repeated showers could produce locally heavy rain. Where the front stalls will help determine where the heaviest rain falls.
What to notice: Compare Saturday’s first echoes near the Rio Grande with Sunday’s radar loops farther east. Watch for successive showers crossing the same area, a pattern called training. NWS Corpus Christi has a Flood Watch for much of South Texas from noon Saturday through Monday morning.

2. Hawaii: Trade winds favor windward slopes
When to watch: Early Saturday, November 7, with fewer showers into Sunday (HST).
Moisture tied to Tropical Storm Pena, well south of Hawaii, had already brought heavy rain to windward Big Island. The deepest moisture had moved west by Friday evening, but easterly trades were still carrying bands of clouds and showers into windward Maui and Big Island. As high pressure builds north of the islands, sinking air strengthens a warmer layer aloft. That layer limits how high clouds can grow.
What to notice: On satellite, follow low cloud bands as they reach east-facing slopes. Compare windward and leeward radar loops as showers become briefer and less frequent.

3. Western Washington: Coastal winds rise before Puget Sound
When to watch: Saturday afternoon, November 7, through Sunday, November 8 (PST).
A strong cold front approaches the coast Saturday evening and is forecast to cross Puget Sound around midnight. Some of the fast southerly winds just above the ground can mix down in gusts. NWS Seattle has a High Wind Warning for the coast and advisories for parts of the interior. Offshore seas may build to 21 to 28 feet late Saturday night into Sunday, and a High Surf Warning starts at 10 p.m. Saturday on the northern Washington and Grays Harbor coasts.
What to notice: Compare coastal and Puget Sound wind reports to see the lag as the front moves inland. Use offshore buoy readings to track the rise in seas from home.

4. Central and northeastern South Dakota: Fog shifts east
When to watch: Saturday morning, November 7 (CST).
Fog formed near the Missouri River overnight and had reached Aberdeen by the early morning update. Near the ground, cooling can bring air to saturation, forming tiny droplets that reduce visibility. Southwest winds kept the fog from spreading west of the river and were expected to erode its western edge as it shifted east. Where temperatures are below freezing, fog droplets can leave patches of light icing.
What to notice: Compare visibility and temperature reports from Pierre and Aberdeen to see when the fog moved through each location. NWS Aberdeen expected dense fog mainly between the Missouri and James rivers through midmorning.

5. Puerto Rico and the U.S. Virgin Islands: Slow showers can linger
When to watch: Saturday and Sunday afternoons, November 7 and 8 (AST), with drier air arriving Monday.
Deep tropical moisture gives showers plenty of water to work with, while weak steering winds allow them to linger. Daytime heating, sea breezes and rising terrain can focus new storms over Puerto Rico’s interior, north and east. Showers can also cross the U.S. Virgin Islands, with a better chance of heavy showers around St. Croix on Saturday. NWS San Juan expects a drier air mass Monday, though localized showers can still develop.
What to notice: On a radar loop, watch whether a cell drifts slowly or new cells form along the same boundary. Either can prolong rain in one spot and raise the risk of localized flooding.
