...HOT, DRY, AND UNSTABLE CONDITIONS FOR MONDAY AND TUESDAY... .A strong ridge of high pressure will bring a period of hot and dry conditions to the central and northern Cascades of Washington early into the week. The ridge will shift east of the Cascades early next week with the atmosphere becoming more unstable at that time. Increased instability with hot and dry conditions will bring the potential for critical fire weather conditions. In addition, we are monitoring the potential for isolated thunderstorms on Monday and Tuesday afternoons that could result in new fire starts. * Affected Area: East Washington Central Cascades (Zone 696), East Portion of North Cascades National Park/Lake Chelan National Recreation Area (Zone 697), East Washington North Cascades (Zone 698) and Methow Valley (Zone 704). * Winds: East-southeast 3 to 7 mph in the afternoon becoming west 5 to 10 mph in the evening. * Timing: Afternoon and evening for both Monday and Tuesday * Relative Humidities: Below 4000 feet: 13 to 20 percent. Above 4000 feet: 20 to 30 percent. * Temperatures: Below 4000 feet: 90 to 102 degrees. Above 4000 feet: 75 to 90 degrees. * Lightning: Isolated thunderstorms over the higher terrain. * Impacts: Hot, dry, unstable conditions may lead to rapid fire growth on any new or existing fires. Isolated thunderstorms will bring the potential for new fire starts.
