This area will be the focus for isolated showers and thunderstorms this afternoon, although odds are only around 15%. Similar odds exist in this area Wednesday afternoon as low pressure lifts across the region. Elsewhere, dry weather will prevail through at least the weekend. An uptick in afternoon west breezes is expected Tuesday and Wednesday in response to the passing low. Winds are not expected to be unusually strong or prolonged, but will be more typical of our summertime zephyr. These breezy winds will overspread daytime RH reductions below 15%, resulting in a brief period of elevated to locally critical fire weather conditions across lower elevations each afternoon. Wednesday will be the windier of the two days, so there may be greater fire impacts over a longer duration compared to Tuesday. Broad high pressure amplifies over the region after Wednesday, allowing for widespread warming that culminates in a late week/weekend heatwave. Regional highs are expected to be near 90F and 100F Friday through Sunday in Sierra and western Nevada valleys, respectively. While this heat isn`t record-breaking, it will impact any outdoor weekend activities as moderate to locally major HeatRisk sets in. Be sure to plan your weekend accordingly, and practice your heat safety precautions if you will be in the heat for extended periods this weekend. -Salas && .AVIATION... Widespread VFR conditions with typical afternoon winds prevail today.
