March 15, 2019 – Dry and mild weather into early next week. Precipitation chances return by the middle of next week.
Clear skies across the region early this morning other than a few high clouds associated with a very weak system passing through. Current temperatures are a mixed bag with lighter winds across most of the region compared to 24 hours ago. Readings vary from the upper teens in the mountain valleys to the 40s and lower 50s across the Central Valley.
Ridging remains in place for the weekend into early next week with gradually milder temperatures expected. Highs are expected to finally reach the 70 degree mark for the first time this year in Sacramento over the weekend and early next week.
Extended Discussion (Tuesday through Friday)
Models continue to differ with progression of next weather system and precipitation timing into the forecast area. The oper GFS is now faster with progression of closed low, spreading precip into the CWA by Tuesday afternoon. EC is about 18 hours slower, developing mostly light precip over interior NorCal Wed morning into afternoon. Given typical slower progression with closed lows, forecast leans more towards the EC with timing. Threat of scattered showers continues Thursday. Another Pacific frontal system and associated polar jet spreads more precip into the area Friday. This storm has potential to produce more widespread moderate to heavy precipitation, but confidence is low this far out. Daytime high temperatures cool from about 5 degrees above normal Tuesday, to 5 or so degrees below normal by Friday.
