KEY MESSAGES

* A gradual warming trend continues, with highs reaching the 90s in lower elevations and 80s near the Sierra for the July 4th holiday weekend and next week.

* Typical afternoon breezes are expected each day through early next week, stay fire safe.

* Afternoon cumulus buildups are likely each day into next week, with a less than 10% chance for brief showers or thunder.

DISCUSSION

Showers with a few embedded lightning strikes developed yesterday afternoon over Mono County, then drifted east over Mineral County yesterday evening. Since the CAMs are favoring a similar outcome today, keep an eye on the sky this afternoon if you are recreating in the Sierra. Low end chances (less than 10%) for showers exist each day through the weekend across the Sierra as we see warmer temperatures. The troughing pattern that has kept us in a more seasonal airmass will try to become more zonal as the weekend approaches, allowing more heat to build in over the region. Daytime highs will reach into the mid 90s for western Nevada valleys this holiday weekend, reintroducing the Minor to Moderate HeatRisk. Elsewhere in the Sierra, 80s to near 90 are expected each day this holiday weekend. Overnights for western Nevada valleys will range 50s and 60s, while the Sierra valleys will see 40s to low 50s for their overnight lows. Daily afternoon gusts of 20-25 mph will increase only slightly this weekend as a shortwave brings gusts of 25-30 mph for Sunday and Monday afternoons. If recreating on area lakes, keep in mind the daily gusts may create choppy lake conditions. Additionally, recent dry conditions have made dry fuels receptive to sparks, so avoid activities that could create sparks, and leave the fireworks to the professionals this holiday weekend.
