Weather

***Isolated thunderstorms to continue through the end of the week***

A dominating ridge of high pressure over the Great Basin will produce hot, humid conditions with isolated mountain storms through the end of the week.  Southeasterly flow around this high is steering moisture into the area, and as a result, minimum RH readings will continue to range from 15-20% over many areas.  Yesterday, about 160 lightning strikes were recorded over the area, mainly across the western Inyo National Forest.  Convection today and Wednesday will be confined mostly to the Sierras, but one or two storms may occur across the Kern County Mountains and across the mountains along the eastern flank of Monterey and San Luis Obispo Counties.  Temperatures will be 10-15 degrees above normal with highs in the 80s along the coast and in the mountains, 100-105 in the valleys and up to 115 in the low deserts.  Winds will be light.  Friday and Saturday, slightly drier air will work into the area, resulting in a bit less thunderstorm activity.  A return of onshore flow will lead to a slow cooling trend Sunday into the first half of next week.  Thunderstorms will continue in the Sierras early next week, but the rest of the area should see more afternoon sunshine with no additional showers or thunderstorms

Fuels/Fire Potential

Very low fuel moisture will lead to high afternoon ignition components each day, despite abnormally high relative humidity.  All lightning strikes pose a threat of producing a new wildfire due to extremely dry fuels.  Dead fuel moisture readings are at or near record low readings in nearly the entire area.  The highest likelihood of seeing a new start will continue to be in the Sierras, the Sierra Foothills and the Inyo National Forest where most of the lightning activity will be.  Light winds and afternoon cloud cover should lead to moderate fire activity.  A bit less lightning can be expected late this week into the 4th of July holiday.  Moderate IA and resource demand will continue through the weekend.
