Here's the latest on the approaching storm:
As of 9:00 Tuesday evening Skytracker Doppler Radar is indicating a line of showers just about to enter the northwest portion of our viewing area. I expect this line to continue moving to the southeast with the front (wind shift) moving through St. Louis about 4:00 AM. Showers and a few thunderstorms are likely overnight with temperatures dropping into the 50s. No severe storms expected.
During the day on Wednesday the rain should continue off and on. At sunrise the temperature should be in the low 50s and continue to fall through the day. Moderate winds of 10 to 15 mph will combine with the rain and cold to make for a very uncomfortable day. As early as 9:00 pm Wednesday evening the rain should begin to mix with or change over to snow. There may be a brief period of sleet at first but by late night (after midnight) we should see a few light snow showers. Temperatures should fall to near or just below freezing by Thursday morning. No significant accumulation of snow expected in the News 4 viewing area although if we do get a brief sleet event roads could become slick for a period.
On Thanksgiving Day we may see a few light flurries early in the day with temperatures only warming into the upper 30s by afternoon. Wind chills will be in the low 30s in the afternoon.
Travelers intending to head north on I-55 or HWY 61 should be prepared for accumulating snow late Wednesday.
