The recent warm weather in St. Louis may soon come to an end as the first frost of the fall season is predicted to arrive next week. Frost typically occurs when temperatures fall between 32 and 36 degrees Fahrenheit, causing moisture to freeze on surfaces. Even if the air temperature is above freezing, frost can still form if surface temperatures cool enough.
FOX 2’s radars are forecasting lows near 38 degrees for Wednesday morning, which could potentially lead to the first frost of the season. This is earlier than the average first frost date of around October 23, based on data from the National Weather Service spanning from 1991 to 2020.
As the temperatures drop closer to freezing, the risk of frost damage to plants, flowers, and crops increases. To protect sensitive vegetation, experts suggest bringing potted plants indoors or using frost fabric covers for outdoor plants. Different areas of the St. Louis region may experience varying frost chances due to environmental factors. For example, areas near river valleys like Chesterfield may be more prone to frost compared to urbanized regions like the City of St. Louis.
Apart from Wednesday, the upcoming week is expected to have temperatures above 42 degrees Fahrenheit, reducing the likelihood of sustained frost. However, it is always a good idea to stay informed about changing weather conditions by using FOX 2’s news and weather apps.
In preparation for the potential frost, residents are advised to take necessary precautions to protect their plants and crops from the cold weather. By staying proactive and monitoring the weather closely, individuals can minimize the impact of the upcoming frost on their gardens and outdoor vegetation. Stay tuned for updates on the evolving weather conditions in the St. Louis area to ensure you are well-prepared for any upcoming frost events.
