ST. LOUIS — Under a bright sky, temperatures warmed well into the 60s across the region Sunday afternoon. Now that the wind has turned to a more southerly direction, warmer weather can be expected for the next several days.
Due to several dry days and the warmer weather, there is an increase in fire danger for Monday afternoon. Relative humidity levels will drop to low levels and the brush is dry. A south to southwest breeze may gust above 20 m.p.h. Outdoor burning should be avoided Monday.
Temperatures will continue to warm through Tuesday with highs around 70. Average high temperatures this time of year are in the low 50s.
A developing weather system will bring an increase in moisture by Wednesday and several disturbances will move through the region into the weekend. The rain chances on Wednesday look limited with just a chance of a few scattered showers and thunderstorms.
By Thursday into the weekend, rain chances increase with the potential for widespread heavier rain increasing. Rainfall amounts will likely be from one to three inches from Thursday through Saturday with locally higher amounts.
After the front comes through later Thursday, temperatures will plummet into the mid 50s for Friday. Showers will continue into the weekend with more temperatures closer to average or perhaps even a bit below.
