Area Forecast Discussion National Weather Service Sacramento CA 1130 AM PDT Mon May 18 2026
KEY MESSAGES
- Red Flag warning expires this evening.
- Less wind rest of the week but above normal temperatures returning with widespread moderate heat risk Thursday.
DISCUSSION
Tonight and Tuesday
The upper trough/inside slider that brought us widespread gusty winds is quickly moving off to the east and causing severe weather in the central U.S. This will shift upper winds from the north to a more zonal westerly directions. In other words, less wind for the rest of the week. Relative humidities will remain low this week but not as dry as today.
Once the pattern settles in on Tuesday/Wednesday it looks to stay pretty consistent. Warmest day looks to be on Thursday with very little spread in maximum temperature in the NBM percentiles.
Currently looks like widespread moderate heat risk with temperatures in the 90s to approaching 100 in the north.
Confidence pretty high that temperature forecast shouldn't change too much. HeatRisk probabilities very low to reach above moderate risk but will keep an eye on this. Things look to cool down enough Friday into the weekend but still very warm. No rain in site right now in the 7 day forecast.
AVIATION
VFR conditions are expected over the next 24 hours. Northerly winds 15-20 kts with gusts 20-30 kts for the Valley and Delta until around 00z-03z Tuesday. Northeast to east wind gusts up to 20-35 kts through mid-day today.
