River valley fog and fog where rain occurred yesterday can be expected this morning. Warm, moist and humid air will allow for some showers and thunderstorms, with the better chances in the mountains. Afternoon temperatures will combine with the humidity to create heat indices at many locations in the lowlands in the upper 90s. Messaging today should stress taking breaks, drinking lots of water, and other tips for avoiding heat stress.-- End Changed Discussion --&& .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...-- Changed Discussion --As of 1235 AM Saturday... The warm, moist and humid air will remain over the region on Sunday, with upper level moisture also increasing as a cold front approaches from the northwest and moves into the region. The front will stall over the area while a wave forms along the front associated with an upper level trough. This wave will cross the area Sunday night into Monday, allowing for some storms outside the typical diurnal pattern. Drier air will move in behind the wave Monday night, although there is some discrepancies between the models on this.-- End Changed Discussion --&& .LONG TERM /TUESDAY THROUGH FRIDAY/...-- Changed Discussion --As of 1235 AM Saturday... A high pressure system will provide drier air for Tuesday. Even so, can`t rule out some afternoon and evening showers and thunderstorms in the mountains. As the high shifts eastward, a southerly wind flow will allow moisture to gradually increase Wednesday into the end of the work week. This will allow for an increasing chance afternoon and evening showers and thunderstorms.-- End Changed Discussion --&& .AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...-- Changed Discussion --As of 1230 AM Saturday...
