PM Update: Chilly tonight as winds diminish, then sunny and warm Wednesday

* Red flag warning until 8 p.m. for a combination of low humidity and gusty winds *

West winds, dry air and dry soils joined forces to send temperatures about 5 degrees higher than expected today. When there are lower humidity values — and today’s dropped very low — it’s easier to warm up the air. West winds also warm up as they come off the Appalachians. If only there was no pollen, it would be just about perfect.
