The metro-east could set a record Wednesday for the lowest high temperature on record for May 14.
According to the National Weather Service, the high will be 56 degrees, 19 degrees lower than the average high temperature for this date in the St. Louis area. If the prediction is correct, that would tie the all-time low high temperature for the date which was set in 2006.
In contrast, last year the high temperature on May 14 in the St. Louis area was 93. That mark set the all-time high for the date.
The cold weather will come with a heavy dose of rain. A 90 percent chance of showers is expected to start after 10 am and last through the day and overnight when the low will drop to 44.
A 50 percent chance of thunderstorms is in the forecast for Thursday, when the high is expected to reach 62. Skies will turn mostly cloudy overnight and then clear to partly sunny by Friday, when the high will be 61.
