Weather

*** Wet weather and some windy periods for the next few days, snow levels lowering ***

 

The second storm in a series of 3 will be moving across North Ops today. Precipitation amounts with this system are expected to be somewhat more than yesterday, but still fairly light overall. Snow levels today will drop to around 5000 ft give or take a few hundred feet. The third/last weather system will move ashore around midday Friday and inland overnight. That system will likely be the wettest of the series. Conditions will turn more showery Saturday in many areas and the snow level may drop to as low as 3000 ft near the Oregon border but be around 6000 ft in the Tahoe area. Higher pressure will start to move into the region Sunday, but it will be a few days before the high strengthens significantly and much warmer, dry weather is over the region for the middle of next week.

 

Many areas will have relatively light southerly winds today, although some of the higher elevations will have moderately strong winds through midday.  Wind speeds will pick up significantly later Friday afternoon and evening with the arrival of the next weather system. Many lower elevation areas can expect wind speeds of 8-18 mph with gusts around 25-35 mph, and the more exposed higher elevations may see speeds on the order of 12-25 mph with gusts 40-55 mph and possibly a bit stronger in some locations. By Sunday the winds will become northerly and much lighter, although still locally breezy/gusty. N to NE winds will continue Monday through next Wednesday and be fairly light at the lower elevations and somewhat breezy in some of the higher elevations.

Fuels/Fire Potential

All areas have already or will soon receive enough rain to hold overall fuel conditions in the "Moist" category through the 7 day period. North aspects and high country locations with lingering snow will see quite moist fuel conditions continue in spite of drying conditions expected under the high pressure ridge early next week.
