Cool Weekend Ending, Milder Start to Work Week

A warm end to the work week last week but cooler air came in for the weekend dropping temps from 50s on Friday to 40s on Saturday and Sunday. We are starting to see those warmer temperatures but unfortunately the way things have setup this month, we are currently running around 10° below normal. Only 2 times this month has the high been above normal while all the lows this month have been below normal. Here's a look at the actual observations so far this month.

NOTE: The average precipitation amount to date is 0.8". We are currently 0.51" below normal. The average snowfall amount to date is 1.10". We are currently 1.3" above normal.

Temperatures will climb for Monday and Tuesday thanks to a warm front and the southerly wind will kick into high gear ushering in those warmer temperatures. We are likely to see the highest temperatures of the year as temps looks to reach the lower 60s. Warmest in around 96 days when we reached 61° on December 4th. These are temperatures more typical for early to mid April. We should see more in the way for sunshine on Monday & 1st part of Tuesday. There could be some clouds streaming in Tuesday afternoon, thickening up in the evening as the next weather disturbance arrives. As colder air interacts with moisture being pulled in from the Gulf this will allow for a few snowflakes to fall Wednesday from a developing powerful low pressure system that would cut though the Tennessee & Ohio Valley and race up the eastern seaboard. There are a few unanswered questions but this storm doesn't appear to be all that complex. We will see rain, we will snow. What we don't know, is exactly where the (colder) northern branch of the jet stream and (wetter) southern subtropical branch of the jet stream will merge at and the speed of the developing low pressure system. Clarity would give an indication as to how much snow may fall. WPC has already outlined a 70% probability that St Louis will see snowfall exceeding 2" by Weds AM. This would shift East throughout the day with the best chance for snow in Indiana in the afternoon or evening hours. Will need to continue to watch trends and modeling data but as of Sunday morning there was some indication the city would see around 4" of snowfall accumulation. THIS IS NOT AN OFFICIAL SNOWFALL FORECAST THOUGHT!



System clears out and sunshine returns for Thursday and Friday. In wake of the passing system, temperatures will back into the lower teens for Thursday morning lows, some areas away from the city may see temperatures dipping in the single digits. Temps will spent the better part of the day below freezing Thursday only reaching a high of around 33°. We'll see a quick jump in temps on Friday only to be dropped back again on Saturday.
