*** More thunderstorms today, especially this afternoon and evening in the north ***

*** Gusty SW to W winds expected Wednesday ***

A small but active weather system will be moving across North Ops today. Plenty of moisture is available for this system to produce cloudiness and showers from the Bay Area northeastward across the Sacramento Valley. A few morning thunderstorms are also expected in those areas. Later this afternoon as the system moves further NE, conditions will stabilize and dry out somewhat in the southern portion of North Ops. Afternoon and evening thunderstorms are then likely develop in the northern areas as the system arrives there. Locally heavy rain, some possible hail and gusty, erratic winds will accompany those storms.

Starting Wednesday, a strong high pressure ridge will move over North Ops as it stretches NW out of the Desert SW over California into Saturday. Gusty SW to W winds will develop Wednesday afternoon behind this system and could significantly fan any ongoing or new fire starts.  The high will also bring much drier conditions with a marked warming trend. Warmest inland areas will be 100-105 by the weekend, which is pretty seasonable for this time of year. Relatively light northerly winds will also be in place.

The flow over the region will become more southerly Sunday into early next week for a return of monsoon moisture working its way northward with a chance of daily isolated afternoon and evening thunderstorms, especially over the eastern mountains and possibly the northern mountains as well.

Fuels/Fire Potential

Although humidity has been higher for the better part of a week now along with some areas getting some precipitaiton, the current fire danger numbers show things to be more dry than moist out there from a fuels perspective. Some areas are probably more in the DRY category for today and Wednesday, but overall conditions appear to be somehere in the VERY DRY category.

Although a lot of the thunderstorms of late have had some good rain amounts with them, holdover fires are an expected reality over the next few days or even for a week or more. The gusty winds Wednesday will help reveal lingering fires and are considered a low-end HIGH RISK event. More new starts are possible Sunday into early next week with the return of afternoon/evening thundestorms.

Most of North Ops is in Extreme to Exceptional drought:
