KEY MESSAGES
* Cool but pleasant weather today and Monday with morning lows near freezing in the Sierra valleys.
* Afternoon breezes return for the second half of next week with summer temperatures and dry conditions for the holiday weekend.
DISCUSSION
No change in the large scale pattern for the next few days. High pressure over the Pacific near 150W will allow cooler weather systems to drop into the Pacific Northwest the next few days.
The current system is moving across northern Nevada this morning with cool north to northwest breezes up to 20-30 mph in its wake. A few light showers extend from Lassen/Plumas Counties to Pyramid Lake and Pershing/Churchill Counties. Showers will either dissipate or move into northeast Nevada by mid-morning. There is a 10-15% chance of showers redeveloping over the Sierra Crest late this afternoon.
On Monday a second compact low pressure system moves south along the California coast. The system brings inside-slider instability and forcing mechanisms, but lacks moisture. It passes just west of the Sierra crest during peak afternoon heating, hard to rule out showers and thunderstorms in this scenario. Plan on a 10-20% chance of late afternoon activity.
For the rest of next week, a broad area of low pressure remains in place over the northern Great Basin and Pacific Northwest. This keeps the door open for energy and moisture to pass over northeast CA and northwest NV leading to 10-15% chances for showers and breezy afternoon winds. Ensembles are picking out Thursday as the best day (30-50% chance) of wind gusts reaching 30-35 mph leading to fire weather and recreation impacts.
Looking ahead to the holiday weekend, conditions will be dry with afternoon highs jumping up into the 80s for the Sierra and 90s across western NV by July 4th. Brong
AVIATION
Light showers from KSVE to KLOL will dissipate by 18z this morning as winds shift to the north and northwest. Peak gusts remain below 30 kts with some mountain wave activity. Afternoon cumulus build ups after 21z are possible along the Sierra between KTVL-KMMH with rain chances below 15%.
A second weather system arrives Monday with 10-20% chance of showers and thunderstorms KTRK-KMMH 21z-03z Tuesday. Brong
