Judging from the plunging dewpoints and jump in pressure a cold front passed through the city between 8 and 9 this morning. It is going to take a few hours for cooler air to arrive, meaning today's high may reach the upper 40s before cooling down after lunch. Clear skies tonight will allow for a lot of cooling and a strong westerly breeze will add to the chill. Tomorrow is looking sunny with seasonable temperatures.......
