12/19 – Brittany’s “Almost Winter” Monday Night Forecast
Tonight, the surface low will approach the LA coast and ride along it as it progresses eastward. This is bringing a second round of showers, more to southern parts of the area, that will continue through Tuesday morning. This second round will have more instability to work with, so thunderstorms are likely to form right along the coast and in the nearshore Gulf waters. We could also see some heavy rainfall with these showers and storms, but it looks limited to coastal areas.
Tuesday afternoon and through Wednesday are expected to be mostly dry following the frontal boundary that passes. Some showers and thunderstorms are possible in the coastal waters Wednesday and lingering into Thursday, but onshore areas should remain dry. As we move into Thursday and Thursday night conditions will start to go downhill as our polar front approaches.
Heading into Thursday, temperatures take a nose dive. That said, winds will remain up through late week. That brings up another potential hazard which is the risk of exposure with wind chills dropping into the teens and perhaps single digits at times. A wind chill advisory may be needed for much of if not all of SE LA and S MS Friday, Friday Night and Saturday. Winds will remain elevated especially during the daytime hours Friday or Saturday if sky condition clear…more mixing could take place again keeping the need for a wind adv. This of course would also start to impact travel with cross winds impacts a large portion of our local highways.
