The high pressure that's been keeping it hot has moved south into Arizona. As a result, temperatures will be slightly lower today. Moisture has increased across Northern and Central Utah, which will bring a slight chance of dry thunderstorms this afternoon and evening. These are most likely over the mountains east of I-15 and across NE Utah. Gusty winds out of these storms will lead to high fire danger in those areas.
