Morning fog gives way to warm, dry Monday

Fog dominates early Monday before a dry afternoon near 81, with high grass pollen and very high ragweed levels adding to the forecast.

Listen to the story

Monday starts with sunshine in some spots, but fog will be the bigger story through the morning, especially early. Temperatures are in the mid-50s to low 60s to start the day, and it can feel a little milder than the thermometer shows. As the fog lifts, clouds and sun will trade places into the late morning.

By afternoon, the day settles into a quiet stretch with a high near 81. Rain is not expected, with just a 3% chance, and east-southeast winds stay light at around 6 mph, with gusts near 8 mph. It may feel closer to 87 during the warmest part of the day, so the air will have a bit more bite than the actual temperature suggests.

During the evening, skies turn partly cloudy and temperatures ease back through the 70s. The dry pattern sticks around, and winds remain light out of the east-southeast.

Overnight, expect partly cloudy skies with a low around 61. It stays calm and quiet with little wind and almost no chance of rain, making for a comfortable end to the day.

The allergy index is worth noting Monday. Grass pollen is high, and ragweed is very high, so allergy-sensitive readers may want to keep that in mind before spending long stretches outside.

Tuesday looks a touch warmer, with a high near 84 and a low around 66. Expect intervals of clouds and sun with dry weather continuing through the day and into the night.
