KEY MESSAGES

* A dry, warm pattern continues through the end of the week with typical afternoon zephyr breezes.

* Temperatures warm through the weekend, with widespread Moderate HeatRisk by Friday through at least next Tuesday.

* No precipitation is forecast for at least the next 7 days.

DISCUSSION

* It's a pleasant Wednesday afternoon with mostly sunny skies, warm temperatures, and overall light winds. Looking at the larger scale pattern, we are under a light northwest flow aloft with an exiting trough to our east and a ridge in the eastern Pacific. * Looking at the evolution of the synoptic pattern through early next week, the high pressure ridge in the eastern Pacific will strengthen and slowly shift over the western US. This will allow for temperatures to increase each day, eventually to around 10 to 15 degrees above average by Friday. Daily high temperatures from Friday to at least Tuesday are currently forecast to be in the low to mid-90s for NE CA and W NV valleys and in the low to mid-80s for the Sierra communities. With these very warm temperatures, the latest NWS HeatRisk product shows widespread Minor to Moderate HeatRisk, especially in the valleys on Friday through Tuesday. By the middle of next week, ensembles show a possible break down of the upper ridge. But, uncertainty remains in whether we return to a trough or zonal pattern. At the moment, the we're dry for at least the next 7 days. -McKellar
