(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 klox 220316 afdlox area forecast discussion... Updated national weather service los angeles oxnard ca 816 pm pdt Mon aug 21 2017 Synopsis A weak upper low just west of point conception will maintain overnight low clouds and fog, along with cooler than normal temperatures through late in the week. As the upper low moves inland... A warming trend is expected starting Friday, with significant warming possible over the weekend. Update The marine layer has shrunk to about 1100 feet and the capping inversion is quite weak. There are 2 mb offshore trends both from the north and the east. There are no low clouds anywhere near coasts. All of the latest mdl guidance shows very little in the way of low clouds for Tuesday morning. Will not buy fully into this idea but did take low clouds out of all areas this evening and totally removed them from the vlys and the sba south coast. Coastal MAX temps were a little warmer than fcst today and with a weaker marine layer expect a little more warming tomorrow. The forecast has been updated to reflect these warmer temps and clearer skies. Short term (mon-thu) between the reduced marine lyr and another 1-2mb of offshore trends most areas should see a few degrees of warming Tuesday, especially the coasts and valleys. A slight onshore trend Wednesday and Thursday may bring a degree or two of cooling to coast and coastal valleys Wednesday but otherwise very little change. Low clouds will continue to push into the valleys overnight and clear to around the coast or just offshore during the afternoon. Monsoon moisture will remain well to the east so no convection expected. Long term (fri-mon) Friday will be the beginning of what appears to be a significant warming trend that will last at least through the middle of next week. Friday and Saturday will just be a couple degrees warmer with still some decent onshore flow in place and low clouds likely still reaching the coastal valleys overnight. By Sunday, however, high pressure is expected to strengthen from the southeast and onshore flow will be weakening quite a bit. Highs expected to reach the triple digits in the warmer valleys Sunday and even warmer Monday. And by next Tue or Wed we could be looking at some weak offshore flow in the morning and highs into the 90s for some coastal areas and well over 100 for the valleys. The door is open for monsoon moisture but models still not showing anything moving into our area at least through early next week. |
